Targeted Protein Posttranslational Modifications by Chemically Induced Proximity for Cancer Therapy

Post-translational modifications (PTMs) regulate all aspects of protein function. Therefore, upstream regulators of PTMs, such as kinases, acetyltransferases or methyltransferases, are potential therapeutic targets for human diseases, including cancer. To date, multiple inhibitors and/or agonists of these PTM upstream regulators are in clinical use, while others are still in development. However, these upstream regulators control not only the PTMs of disease-related target proteins, but also other disease-irrelevant substrate proteins.

Application Management

On #scienceTwitter, my favourite thing was reading and, on rare occasions, writing "paper/preprint threads". From the researchers I followed and through the #Twitter algorithm, this became my most important source for new #research.

While people start to do the same on #Mastodon, I have the feeling that I miss important work bc no algorithm "saves" it for me if I don't watch my timeline constantly.

Two simple solutions would be: a commonly accepted hashtag that everybody uses when writing "paper threads" or an [...] @ a.gup.pe group with a similar adaptation rate.

#Question 1: is there already a mechanism for this that I missed?
#Question 2: What hashtag or group name?
I saw #TootPrint before. Maybe #PaperInAToot? #PaperInAPost? #PaperInAThread? #PaperPost? #MastoPrint?

Suggestions and boosts, please, we need reach for this! 🤓​

Brilliant new paper by Naomi #Oreskes, concluding that "our overall situation suggests that it does not suffice for scientists simply to supply #factual #information, and leave it at that. Scientists need as well to engage actively with the recipients of that information." https://link.springer.com/article/10.1007/s43538-022-00121-1
The trouble with the supply-side model of science - Proceedings of the Indian National Science Academy

Many scientists operate under a mental model that I label the “supply side model of science.” It assumes that the job of scientists is to supply information that governments and citizens can use to make good decisions, and that governments and citizens will use that information once they have it in hand. Therefore, scientists need only do their job—which is to supply accurate, high quality, well vetted information—and all will be well. Events of the past few decades have challenged this model severely. Across the globe, governments and citizens have rejected established scientific findings on climate change, on evolutionary biology, on the safety and efficacy of vaccines, and other issues. Typically, this rejection is ‘implicatory rejection.’ That is to say, people reject or deny science not because the science is weak, unsettled or too uncertain to inform decision-making, but because they and don’t like the actual or perceived implications of that science. In some cases, for example evolutionary biology, the perceived implications are erroneous; in these cases, scientists can help to clear up misunderstandings by engaging seriously (and not dismissively) with people’s concerns. In other cases, for example climate change, the perceived implications may be partly true. In these cases, scientists may help by suggesting ways in which the negative implications might be mitigated or redressed. Often, this will require collaborating with other experts, such as experts in communication, religion, or public health. But whatever the details of the particular case, our overall situation suggests that it does not suffice for scientists simply to supply factual information, and leave it at that. Scientists need as well to engage actively with the recipients of that information.

_ We found that unlike canonical CD8+ #TCell activation seen against viral infections where T cells rapidly acquire effector function, #tumor -specific CD8+ T cells proliferate in TDLNs but fail to express effector molecules. _

_ In human TDLNs, these cells could have been in this state for years. These undifferentiated cells instead turn on co-stimulatory receptors and several chemokine receptors and slowly migrate to the tumor._

Nice addition to the #targetedproteindegradation literature but I wouldn't describe it as "a new strategy of targeted protein degradation through direct substrate recruitment to the 26S proteasome" since Janse and Church first described this approach in 2004. https://pubmed.ncbi.nlm.nih.gov/15039430/ #PROTACs
Targeted degradation via direct 26S proteasome recruitment - Nature Chemical Biology

Discovery of macrocyclic ligands to the 19S regulatory particle protein PSMD2 enables the synthesis of heterobifunctional molecules that demonstrate proof-of-concept, targeted degradation of BRD4 through direct engagement of the 26S proteasome.
