As I wish to bore my readers by endlessly repeating it, there’s nothing new beneath the solar in relation to antivaccine misinformation. Each single antivax trope about COVID-19 vaccines that so stunned lots of my colleagues when it first confirmed up has been immediately traceable to previous antivax tropes going again many years. That features claims that vaccines one way or the other “completely alter your DNA”—”homologous recombinaltion tiniker” and “molecular mimicry,” anybody?—and thereby trigger a bunch of issues, corresponding to autoimmune ailments and even most cancers. Final week, I mentioned how antivaxxers twisted a research to falsely blame COVID-19 vaccines for “accelerated growing old” resulting in—you guessed it!—most cancers. This week, I’m going to have a look at some extra of the “proof” being promoted by antivaxxers as “proof” that the evil COVID-19 vaccines are killing youthful folks left and proper by inflicting most cancers, a 14,000% enhance in “turbo most cancers,” even.
Earlier than I dig in, although, let me simply remind everybody that simply because within the realm of antivax disinformation “all the things previous is new once more” with COVID-19 doesn’t imply that the COVID-19 vaccine-related variations of previous antivax tropes haven’t gained new twists. Within the case of the antivax declare that vaccines trigger most cancers, the brand new COVID vaccine-related twist is that the brand new mRNA-based COVID-19 vaccines don’t simply trigger one thing as mundane as your run-of-the-mill cancers of the kind that, taken collectively, are the second main explanation for loss of life after heart problems. Oh, no. They’re too terrible to trigger simply run-of-the-mill common cancers. They’re such super-powerful magical carcinogens that they trigger “turbo cancers” described by antivaxxers as cancers that develop and develop so quickly as to be primarily untreatable or cancers, beforehand in remission, that spring again to life, because of the mRNA itself or minute portions of contaminant plasmid DNA fragments from the plasmid used to generate the mRNA left over from the manufacturing course of. By no means thoughts that we know from the atomic bombings at Hiroshima and Nagasaki that the shortest interval for the event of most cancers after publicity to some of the potent carcinogens identified (ionizing radiation) is round two years for leukemias and ten years for strong cancers. As compared, COVID-19 vaccines have solely been round somewhat greater than three years and the claims of “turbo cancers” began lower than two years after they had been first granted emergency use authorization (EUA). Tellingly, for probably the most half, it’s not “turbo leukemias” being blamed on the vaccines, however “turbo” strong cancers of the kind that take over 10 years to develop.
After all, this newest “proof dump” billed as “TURBO CANCER Literature is rising quickly – 6 new COVID-19 Vaccine Turbo Most cancers papers printed in April 2024 – 26 complete – the dam is breaking and it’ll take Pfizer & Moderna with it“) comes from disgraced and delicensed nuclear medication doc Dr. William Makis, one of many originators and now one of many foremost promoters of the “turbo most cancers” lie. I’m not going to cowl all the articles, though I observe that I’ve already mentioned a few of them and why they don’t seem to be good proof for a hyperlink between COVID-19 vaccines and most cancers, “turbo most cancers” or in any other case. A part of the rationale Makis’ publish received my consideration is as a result of one of many research is a preprint printed by somebody whom I’ve mentioned earlier than, a director of a most cancers heart who has demonstrated himself to be far too receptive to fancifully implausible claims of a “organic mechanism” to elucidate how COVID-19 vaccines can supposedly combine into genomic DNA and thereby trigger most cancers, despite the fact that he ought to actually, actually know higher. (Worse, he doubled down in response to even well mannered, respectful criticism.) I’m referring to Dr. Wafik El-Deiry, somebody whom I really fairly admired again within the Nineties as a graduate scholar and later postdoc, certainly, from then till comparatively lately, once I observed him granting an interview to an antivax propagandist. Let’s simply say that I’ll agree that the “turbo most cancers” literature is rising, slightly like maggots on a rotting wound of unhealthy science.
Et tu, Dr. El-Deiry?
That Dr. William Makis is an antivax quack is a degree that I’ve made a number of occasions right here and at my not-so-super-secret different weblog, bringing the receipts, after all, that led me to that unlucky conclusion. As for Prof. Wafik El-Deiry, I’ve famous earlier than how he is an surprising supply to have been so credulous about claims of somebody like Phillip Buckhauts, who has been furiously selling claims that fragments of the SV40 promoter within the fragments of plasmid DNA left over from the vaccine manufacturing course of are “integrating” with genomic DNA and inflicting most cancers. That’s as a result of Dr. El-Deiry is an oncologist and most cancers biologist whose work influenced me as a graduate scholar 20 years in the past and who’s now the director of the Legorreta Most cancers Middle at Brown College. He’s been an enormous identify in p53 analysis for 30 years. I hadn’t heard a lot from him for a number of months, however now apparently he’s making an attempt to publish an article describing experiments that, properly, take a look at the title of his preprint: SARS-CoV-2 spike S2 subunit inhibits p53 activation of p21(WAF1), TRAIL Loss of life Receptor DR5 and MDM2 proteins in most cancers cells, posted per week in the past to the bioRxiv preprint server.
In equity, one may argue that this research isn’t concerning the vaccine in any respect, however slightly SARS-CoV-2 an infection, and that that is simply one other instance of an antivaxxer like Dr. Makis willfully misinterpreting a research to hyperlink it to the “turbo most cancers” narrative, an instance of which I simply mentioned final week. Perhaps, though antivaxxers appear to interpret the paper in any other case, given the solutions to his Tweet concerning the preprint:
Once more, this might simply be antivaxxers willfully misinterpreting, however…
Earlier than I get into the experiments, let’s simply unpack a few of the summary:
Extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and COVID-19 an infection has led to worsened outcomes for sufferers with most cancers.
That is, after all, true sufficient, however, I believe, not for the explanations that Dr. El-Deiry goes to argue. Fairly, any extreme infectious illness goes to result in poorer outcomes for sufferers with most cancers, if solely due to the disruption of therapy and by making them sick from a trigger apart from the most cancers. Nonetheless, do go on, Dr. El-Deiry:
SARS-CoV-2 spike protein mediates host cell an infection and cell-cell fusion that causes stabilization of tumor suppressor p53 protein
On condition that p53 is a tumor suppressor, the “guardian of the genome,” even, one may assume that this could really make one much less vulnerable to most cancers; that’s, if it actually occurs. That’s why I needed to go to the precise textual content to see what Dr. El-Deiry meant:
An in-silico evaluation utilizing HADDOCK 2.2 software program beforehand steered that p53 and BRCA1/2 might work together with the heptic repeat-2 area of the S2 subunit by way of C-terminal area [6]. DNA harm or therapy-induced tumor suppressor p53 protein transcriptionally prompts genes resulting in a number of results preserving genome integrity, altering metabolism, immune response, cell cycle, DNA restore, cell progress and cell apoptosis to stop or eradicate reworked cells [7]. Lack of p53 perform will increase the incidence of carcinogen-induced tumorigenesis and drives chemo-resistance [8]. SARS-CoV-2 an infection has been discovered to change p53 stabilization. The earlier research have proven that SARS-CoV-2 spike particularly performs a job to stabilize and activate p53 by mediating cell-cell fusion or induction of ROS in host cells throughout SARS-CoV-2 virus an infection [9, 10]. In response to mobile stress, activated p53 regulates particular gene expression, together with MDM2 (E3 ligase). MDM2, in flip, binds to p53 and triggers p53 ubiquitination and proteasomal degradation [11], whereas interruption of MDM2-p53 interplay results in p53 stabilization. Thus, a putative interplay between SARS-CoV-2 spike, p53 and p53 associated signaling pathways following SARS-CoV-2 an infection may influence mobile homeostasis, tumorigenic pathways, and/or response to most cancers therapeutics.
I observe that the research dates again to 2020 and that I’ve beforehand famous that the findings of this research, even when the research pans out, mentioned nothing concerning the vaccine; slightly, it was about persistent SARS-CoV-2 an infection, not vaccination. The vaccine solely transiently produces the spike protein, which is quickly externalized. If it weren’t externalized, then it wouldn’t have the ability to provoke an immune response. p53 isn’t just an intracellular protein, however, not like the spike protein, is primarily a protein of the nucleus. Vaccination is transient by nature, and, even when this proposed interplay had been related, would require extended interplay between spike and p53. In equity, at this level, Dr. El-Deiry hasn’t talked about the vaccine…but. He’s solely talked about SARS-CoV-2 an infection. Furthermore, what he appears to be saying is that the spike protein prompts p53, not deactivates it, the latter of which being obligatory for most cancers formation. Actually, nearly nowhere does Dr. El-Deiry even point out the vaccine. Nevertheless, the place he does point out it, I believe he provides the sport away, as you will notice.
I may even observe that this preprint is a bit skinny in that it solely has 4 figures. That doesn’t imply that it’s flawed and even not good science, simply that not a whole lot of info is there. Personally, I really want extra journals would publish shorter, punchier papers with just one or two key findings, slightly than insisting on ten-figure, many thousand phrase epics. Be that as it could, let’s summarize the important thing findings. First, nevertheless, observe that we are able to’t describe the findings with out inspecting the strategies first, beginning with the cell traces used: human lung most cancers cells H460, breast most cancers cells MCF7, colorectal most cancers cells HCT116 (p53 wild-type or p53-null), and sarcoma cells U2OS with p53-knockout (U2OS-P53KO). One can see why he would select a few of these cell traces, notably those missing p53, if one needs to check whether or not SARS-CoV-2 spike protein interacts with p53. In any occasion, these cells had been transfected with a plasmid designed to supply the S2 unit of the spike protein:
The plasmids pcDNA3.1-SARS2-spike (#145032) and p-CMV-Neo-Bam-p53wt (#16434) had been obtained from Addgene.
Earlier than I even take a look at the outcomes of the experiments during which this plasmid is used, I had questions. Perhaps a few of my extra superior molecular biology colleagues extra acquainted with SARS-CoV-2 than I may help out. Even a surgeon-molecular biologist like myself is aware of that the SARs-CoV-2 spike protein is product of two subunits, S1 and S2. The S1 subunit incorporates a receptor-binding area that acknowledges and binds to the host receptor angiotensin-converting enzyme 2 (ACE2), whereas the S2 subunit mediates viral cell membrane fusion. Furthermore, the inactive S protein exists as a single peptide, however is activated by cleavage into S1 and S2 by mobile proteases throughout an infection.
If you happen to take a look at the assemble on the corporate’s web site, it states that it encodes the complete size spike protein, which makes me marvel: When the protein is made in most cancers cells, is it processed and cleaved into its subunits S1 and S2 at its furin cleavage website the best way {that a} regular spike protein is? The explanation I ask it is because at some factors within the manuscript the product made by the plasmid is described as S2, whereas in different components it’s described as spike. We all know that the spike protein is 1,273 amino acids in size. A virologist whom I requested about this talked about that all through the paper there are references to “S2 expression,” questioning whether or not this was simply sloppy terminology or whether or not one other reagent was used. He additionally puzzled whether or not most cancers cells—bear in mind, all of the cell traces used are most cancers cells—can proteolytically course of the S protein into S1 and S2? I don’t know the reply to that query, but when I had been reviewing the paper I’d require that the authors reply the query, both with the literature or with further management experiments.
Let’s simply describe what the research exhibits as described by its authors. The authors did an immunoprecipitation experiment, which entails utilizing antibodies to precipitate a protein, however used a considerably extra complicated model that may decide if different proteins are connected to the precipitated protein. For easy IP, in short, an antibody (monoclonal or polyclonal) towards a selected goal protein is used to kind an immune complicated with that focus on in a pattern, corresponding to a cell lysate. The immune complicated is then captured, or precipitated, on a beaded assist to which an antibody-binding protein is immobilized (corresponding to Protein A or G). Any proteins not precipitated on the beads are then washed away. Lastly, the protein is separated from the antibody and run by way of a polyacrylamide gel for Western blot detection.
Briefly, First, right here’s a diagram describing the essential idea of immunoprecipitation (IP):
However what about co-precipitation? The primary distinction is that what’s precipitated and analyzed are complexes of the 2 totally different proteins:
You don’t must know the superb particulars, however slightly to grasp the co-IP is a take a look at to see if two proteins bind to one another and, in that case, by how a lot. As I realized myself throughout graduate college and later throughout my fellowship analysis, IP is usually a difficult approach, co-IP much more so. It may be influenced by a whole lot of issues and the co-precipitation of two proteins doesn’t essentially in and of itself show that two proteins bodily work together with one another. For instance, they might simply be in the identical subcellular fraction.
The immunoprecipitation experiments reported seem to indicate that there was lowered interplay between p53 and a protein known as MDM2 following SARS-CoV-2 spike S2 overexpression in these cell traces. Extra particularly, the IP assay confirmed that MDM2 protein sure to p53 within the cells, whereas cells with “SARS-CoV-2 spike S2 subunit” overexpression displayed lowered quantities of MDM2 sure to p53 when in comparison with what was noticed with the empty vector transfection management. In some experiments, most cancers cells had been uncovered to cis-platinum compounds, which induce double-stranded DNA breaks and activate the DNA restore system in cells, as evidenced by elevated activated p53. Since MDMs and p53 are identified to work together with one another, the query of whether or not MDM2 really binds to p53 itself is just not a lot a problem. Nevertheless, what’s fascinating is that the paper itself exhibits that p53 and the S2 protein localize in numerous components of the cell, and p53 doesn’t co-preciptate with SARS-CoV-2 spike S2:
Our observations from lack of co-immunoprecipitation between p53 and the SARS-CoV-2 spike S2 protein subunit are according to totally different mobile areas of SARS-CoV-2 spike S2 and p53 within the most cancers cells handled with cisplatin (Determine 1C). The immunofluorescence imaging confirmed that almost all of p53 was localized within the nuclei, whereas nearly all of SARS-CoV-2 spike S2 subunit was localized within the cytoplasm in H460 cells handled with cisplatin (Determine 1C). These outcomes don’t show SARS-CoV-2-spike S2 subunit protein binding to wild-type p53 in most cancers cells both within the absence or presence of cisplatin therapy. As it is a protein subunit, and a few small quantity of nuclear staining is noticed, we can’t exclude that spike S2 can acquire entry to the nucleus or that intact spike may accomplish that as properly.
In further experiments, it was proven that transfection of cells that don’t specific any p53 with the plasmid expressing p53 ± pcDNA3.1-SARS2-spike (the plasmid making spike) resulted in decreased transcriptional exercise by p53, particularly as measured by co-transfection with a PG13-luciferase reporter gene. This explicit plasmid incorporates 13 copies of the p53 binding website connected to the gene for luciferase. Principally, the extra lively p53 in a cell, the extra bioluminescence might be measured. Now, I do know from private expertise that these experiments are additionally difficult to do, however I’ll admit that this determine is pretty convincing that, nevertheless it does it, the presence of S2/spike does seem to lower the exercise of p53 within the cell:
However what does this must do with most cancers? Effectively, Dr. El-Deiry takes it again to p21, one of many genes turned on by p53 whose perform is to induce cell cycle arrest, and finds that p21 doesn’t enhance almost as a lot in response to cis-platinum chemotherapy in cells transfected with pcDNA3.1-SARS2-spike because it does in cells transfected with management empty vector despite the fact that p53 ranges enhance by the identical quantity. Comparable outcomes had been proven with TRAIL Loss of life Receptor DR5 (which contributes to apoptosis or programmed cell loss of life), and MDM2.
So what does all of it imply? Hell if I do know. To start with, these research had been all executed in most cancers cells, not regular cells. The authors observe that their outcomes differ from different stories:
Our findings differ from earlier stories which have proven that SARS-CoV-2 spike stabilized p53 and activated p53 [9, 10]. Within the earlier research, the p53 activation and stabilization was brought on by the spike-ACE2 mediated cell-cell fusion and a rise in ROS in most cancers or regular cells [9, 10].
One of many research cited was executed in retinal pigment epithelial (RPE) cells, which aren’t most cancers cells, which may make a distinction, whereas the different research included human tissue from postmortem examinations, however did embrace most cancers cell traces and non-cancer cell traces. In any occasion, there are additionally quite a lot of weaknesses on this research as properly, which, in equity, the authors acknowledge. One is a biggie:
We’ve not performed in vivo experiments and a few of our experiments lack further controls corresponding to in movement evaluation or by kinetics of cell cycle checkpoint regulation. We’ve not evaluated regular cells corresponding to airway, muscle, immune, mind or intestinal cells. Biking vs quiescent cells are additionally essential to analyze for potential differential results of spike or different SARS-CoV-2 proteins. We’ve not investigated immune cell interactions corresponding to NK or T-cells in our experiments the place spike S2 protein was overexpressed in tradition. These would all be cheap early future instructions.
“A few of our experiments lack further controls”? Maybe these controls ought to have been executed for this manuscript. Maybe the authors ought to have checked out biking versus quiescent (non rising) cells. Perhaps the authors ought to have checked out some regular cells, corresponding to airway, muscle, immune, mind, or intestinal cells. Maybe in vivo mouse experiments ought to have been executed. Perhaps a few of these experiments are being executed for the submitted model and, for some motive, Dr. El-Deiry was anxious for as many individuals as potential to see this.
To this point, a case may be made that that is simply one other paper being deliberately misinterpreted by antivaxxers as proof for “turbo most cancers.” In actuality all this paper exhibits is that, in cell tradition, it’s potential that SARS-CoV-2 an infection may intrude with p53 exercise. After all, in cancers during which p53 is already inactivated or mutated, these findings would possible have little applicability. In spite of everything, p53 is already mutated and nonfunctional in these cancers. Would these findings inform us something about how SARS-CoV-2 may have an effect on most cancers response to chemotherapy? Perhaps to cis-platinum in sure cell varieties, however that’s about it to date. Principally, general it’s a research in most cancers cells in dishes utilizing a man-made system during which plasmids coding the related proteins utilizing a liposome-based system to introduce the DNA into the cells, after which the cells had been damaged open and the extracts subjected to immunoprecipitation.
Taking probably the most charitable view of the research, I discover it mildly fascinating, however far too preliminary to make a lot of a conclusion about and lacking related controls, which might be one motive why it’s a preprint slightly than submitted to the top quality journals during which Dr. El-Deiry has normally printed over the past 30 years. I’m undecided that it provides a lot to what we already find out about spike protein and SARS-CoV-2 an infection.
Nevertheless:
Our outcomes have implications for the organic results of spike S2 subunit in human cells whether or not spike is current as a result of major COVID-19 an infection or as a result of mRNA vaccines the place its expression is used to advertise anti-viral immunity. A perturbed p53 pathway is regarding but in addition difficult in finding out since mobile transformation and most cancers are a multi-step course of that evolves over time. Additional detailed research can extra totally characterize the consequences of spike, in addition to structural determinants throughout the protein for interplay between the DNA harm sensing and response pathways in addition to the p53 tumor suppressing pathway. With respect to the p53 pathway, additional research are wanted to unravel how much less MDM2 is sure to p53 within the presence of spike and the mechanisms underlying lowered p21(WAF10), TRAIL Loss of life Receptor DR5 in addition to MDM2 beneath situations the place there’s much less degradation of p53 as a result of lowered interplay with MDM2.
“Whether or not spike is current as a result of major COVID-19 an infection or as a result of mRNA vaccines the place its expression is used to advertise anti-viral immunity”? Antivaxxers have observed:
In the meantime:
The remainder of the Tweet:
However clearly lack of p53 is related to most cancers over time. It’s a troublesome space when one discusses “causes.” It’s like explanation for loss of life. There’s a right away trigger however there may be many contributing elements.
We’d like extra science and analysis to have a strong information base and concrete plans to deal with dangers. Analysis takes time, prices cash, and must be higher supported within the US to proceed to have growing influence on well being, high quality of life and even prices of healthcare.
So did Dr. El-Deiry imply his point out of the vaccine, which was nearly a throwaway, as a canine whistle to the antivax motion blaming the COVID-19 for “turbo most cancers”? Who is aware of? Solely he can reply that for certain. I do know that, given his previous historical past of credulity to the concept that minute quantities of contaminating DNA from the COVID-19 vaccine, SV40 particularly, trigger most cancers, antivaxxers had been assured to latch onto this paper as extra proof for “turbo most cancers,” whether or not Dr. El-Deiry meant it that approach or not.
However what concerning the different “proof”?
I spent longer than I had anticipated discussing Dr. El-Deiry’s paper, primarily as a result of it’s precise primary bench science and I don’t get to debate primary bench science as a lot as I like. One different paper that I positively haven’t mentioned earlier than was cited by Dr. Makis that I’d properly have to debate, though the dialogue may be executed at my not-so-super secret different weblog. As for the opposite “proof,” it largely consists of case stories, corresponding to this preprint (leukemia in a younger girl after the second dose of the Moderna vaccine, as if younger folks by no means received leukemia earlier than the vaccine) this paper (hemophagocytic lymphohistiocytosis with intravascular massive B-cell lymphoma after her second dose within the presence of immunosuppression as a result of lupus), and this case report (Main Cutaneous Adenoid Cystic Carcinoma in a Uncommon Location With an Immune Response to a BNT162b2 Vaccine), none of which really present that the vaccine precipitated the most cancers.
Once more, I’m not saying that each scientifically cheap concern about vaccines which have been distributed to billions of individuals now shouldn’t be the topic of scientific investigation. What I differ about is what constitutes a scientifically cheap concern. Dr. Makis’ “considerations” are something however cheap, whereas I’ve discovered Dr. El-Deiry to be both willfully or simply painfully naive. Both approach, he nonetheless appears totally unaware of the well-funded networks that exist to unfold misinformation and/or he’s sympathetic to the misinformation being unfold. Worse, his newest research doesn’t actually present any new info of worth with respect to the query of whether or not SARS-CoV-2 an infection has any impact on most cancers threat or improvement.
