Your mRNA and Cancer Suppression – mRNA vaccine ‘teaches our bodies to make a protein” ?
On a theme of viruses, vaccines and cancer..
Common Cold Virus Kills Off Cancer- As Do Other Viruses- Interesting!
To this interesting report:
Most people think of cancer as a disease of disorderly DNA. Changes, or mutations, in the sequence of DNA alter the function of the proteins made from that DNA, leading to uncontrolled cell division.
But between DNA and proteins is another layer of information, called messenger RNA (mRNA), which serves as a crucial link between the two. New research suggests that mRNA itself may carry cancer-causing changes. And, because genetic tests don’t usually look at mRNA, those changes have so far gone undetected by cancer doctors.
“New research suggests that mRNA itself may carry cancer-causing changes.“
From DNA to mRNA
If DNA is the genetic blueprint for life, as is often said, then it’s a fairly cumbersome set of instructions. The information in DNA is encoded in the particular sequence of some 3 billion nucleotide “letters” — varying combinations of A, T, G, and C. Blocks of these letters — genes — are used to make particular proteins, a cell’s main workhorses. But DNA lives in the nucleus of a cell, while proteins are made in the surrounding cytoplasm. To bridge this gap, a cell must first make an RNA copy of a gene’s DNA. This RNA copy, called messenger RNA, is then transported out of the nucleus. It is this mRNA copy that cells read and translate into a protein.
Usually, the mRNA copy is a bit shorter than its DNA precursor. That’s because the useful pieces of information in DNA, called exons, are often separated by blocks of sequences that are not needed. These unnecessary parts, called introns, must be cut out to make a final product. After the introns are removed, the remaining exons are spliced together, not unlike splicing together pieces of film and leaving some on the cutting room floor.
These findings help explain a long-standing conundrum, which is that CLL cells have relatively few known DNA mutations.
If the mRNA copy doesn’t include all of the exons in a gene or is cut short, then the protein made from that mRNA will also be truncated. It may no longer function properly. And if that protein is a tumor suppressor — one that protects against cancer — then that could spell problems.
What Dr. Mayr and her colleagues, including postdoctoral fellow Shih-Han (Peggy) Lee, graduate student Irtisha Singh, and SKI computational biologist Christina Leslie, found is that many of the mRNAs in cancer cells produce these truncated tumor-suppressor proteins. The changes occur not only in known tumor-suppressor genes but also in previously unrecognized ones.
“The changes to the mRNA make proteins that are very similar to the proteins that are made when you have a mutation in the DNA that causes a truncated protein to be made,” she says. “In the end, the outcome for the cell is very similar, but how it happened is very different.”
Found: Missing Cancer Mutations
Dr. Mayr’s team looked specifically at chronic lymphocytic leukemia (CLL), a type of blood cancer. A colleague at MSK, Omar Abdel-Wahab, supplied them with blood samples from people with the condition. Using a method that Dr. Mayr’s lab developed to detect these particular mRNA changes, they found that a substantially greater number of people with CLL had an inactivation of a tumor-suppressor gene at the mRNA level than those who had it at the DNA level.
These findings help explain a long-standing conundrum, which is that CLL cells have relatively few known DNA mutations. Some CLL cells lack even known mutations. In effect, the mRNA changes that Dr. Mayr’s team discovered could account for the missing DNA mutations.
Because CLL is such a slow-growing cancer and people with CLL often live for many years, it’s too early to say whether these mRNA changes are associated with a poorer prognosis.
There are some important differences between the mRNA changes and a bona fide DNA mutation. Most important, the inactivation of tumor suppressors through mRNA is usually only partial; only about half of the relevant protein molecules in the tumor cells are truncated. But in many cases this is enough to completely override the function of the normal versions that are present. And because this truncation could apply to 100 different genes at once, the changes can add up.
Lessons for Cancer Diagnostics
Though Dr. Mayr’s team identified the mRNA changes in CLL, they’re likely not limited to this blood cancer. The team found them in samples of T cell acute lymphocytic leukemia too, for example. Other researchers have found them in breast cancer. Dr. Mayr hopes that scientists will be inspired to explore the significance of mRNA changes in these and other types of cancers.
“Current cancer diagnostic efforts predominantly focus on the sequencing of DNA in order to identify mutations,” Dr. Mayr says. “But our research suggests that changes at the mRNA level might be as frequent.”
In other words, cancer diagnostics may need to change to include these previously unknown cancer drivers.
If you’ve been paying attention to the way the experimental covid vaccine is supposed to work, then you are or should be aware, that the vaccine, as claimed by the CDC alters our mRNA
“MRNA vaccines teach our cells how to make a protein—or even just a piece of a protein—that triggers an immune response inside our bodies.”
Keeping in mind there are no long term studies for this vaccine. It was not approved, only authorized for emergency use.
Why bring this post back from more than 2 years ago? mRNA can cause cancer changes. This RNA copy, called messenger RNA, is then transported out of the nucleus. It is this mRNA copy that cells read and translate into a protein. mRNA changes may trigger cancer cells. Noticing cases of cancer, rapid onset and demise being connected to mRNA jab recipients.

The idea of viruses having medical benefits reminds me of something I ran across a couple of years ago after the scamdemic started and i was doing some reading of Microbiology.
Bacteriophages are viruses that, as the names implies, eat bacteria. they have potential medical benefits as they are specific to particular bacteria, thus naturally only targeting the “pathogen.”
Make of it what you will, conspiracy or not, but let me present some very interesting excerpts from the Forward to “The Bacteriophages (2nd edition)” (Oxford University Press, 2006):
“In a real sense, the field of bacteriophage biology died, was buried and plowed under, but is now arising again as vigorous fresh green shoots from the soil so thoroughly enriched. The evidence of its death is indisputable. If you do a search of the NIH CRISP database for grants with bacteriophage in the title in the years of 1972 and 2002, the numbers come up approximately the same, above 200. However, a closer look reveals that most of the projects funded by NIH in 1972 involved research in which plaques were generated every week in the natural course of experimentation.”
This paragraph in particular I found EXTREMELY interesting:
“It should be a topic of some interest for science historians to explain how a field with so much momentum and so many talented practitioners suddenly turned its own lights off and just walked out the door. It was an exodus of talent and leadership of a scale, breadth, and suddenness never seen before in any field of biology, and perhaps in any field of modern science.”
“It also turns out, mirabile dictu, that phage are involved in many aspects of bacterial evolution and pathogenesis. Indeed, many diseases and most dissemination of virulence factors are basically phage phenomena, despite the decades-long aversion of funding agencies to consider phage as relevant to human disease.”
“Moreover, phage are now being found to be sources of genetic information useful in combating drug-resistant pathogens, which should have been obvious long ago.”
Let me emphasize that last bit, “should have been obvious long ago.”
“In fact, much of this volume is written by members of the new wave. And, not least, phage are now being tamed and harnessed themselves as therapeutic agents, more than half a century after d’Herelle’s lonely, ostracized demise.”
“Which brings us back to this book. Have you ever tried to find an up-to-date, comprehensive compendium of phage biology? Well, until now, you had very few choices, and most of them were out of print. As you will see, many of the chapters of this book are written by recognizable veterans of the classical phage years, but also many are written by new practitioners, some of whom didn’t arrive at this juncture intentionally. They simply followed the science, and the science of microbiology is now coming back, full circle, to bacteriophage.”
thanks dan quixote! and that’s an enthusiastic thank you too.
First thanks for reading the post on viruses and their ability to kill cancer– that was the first I had come across that type of information. And now you bring a bit more interesting info to the table, so to speak.
I would expect, based on my knowledge gained through life experience (reading too much) that the reason this field, though promising, met it’s demise is because another path was chosen, the path of every bit of virus and bacteria being bad (non beneficial) and needing to be killed off- which happened to be a profitable path as well, very profitable.
“However, a closer look reveals that most of the projects funded by NIH in 1972 involved research in which plaques were generated every week in the natural course of experimentation.”
So, if I’m understanding this sentence correctly as experimentation was conducted these plaques generated themselves as a natural response?
Interesting- bacteriophage-? I’ll keep an eye out for any information of this type
