AI tool may help doctors select best drugs for COVID patients

pharmaphorum

Researchers in the US have developed an artificial intelligence-based tool that is able to predict COVID-19 symptoms and suggest which FDA-approved drugs might be used to treat patients. The tool meanwhile could also be applied to new outbreaks of other novel viral infections as they emerge, according to the scientists.

Quantitative approach on understanding how epigenetic switches control gene expression

Scienmag

Credit: Nucleic Acids Research Scientists at Tokyo Institute of Technology decipher how to quantitatively assess the effects of specific epigenetic changes on the rate of transcription by developing a mathematical model. For this, they successfully generated reconstituted chromatin bearing histone modifications in vitro.

Discovery of MicroRNA Genetic Regulation Leads American Scientists to Win 2024 Nobel Prize

XTalks

The 2024 Nobel Prize in Physiology or Medicine has been awarded to American scientists Victor Ambros and Gary Ruvkun for their groundbreaking discovery of microRNA (or miRNA) and its role in post-transcriptional gene regulation. A gene contains instructions within our DNA.

Scientists uncover a new approach for treating aggressive cancer

The Pharma Data

Researchers at the University of North Carolina at Chapel Hill and the UNC Lineberger Comprehensive Cancer Center have uncovered a new role of a chromatin-modulatory enzyme, termed EZH2, during cancer development. They then developed a new therapeutic approach with a potent small-molecule inhibitor of this enzyme.

Epigenetic Editing with CRISPR Might Be Easier Than We Thought

XTalks

Researchers at the University of California San Francisco (UCSF) and the Whitehead Institute have developed a novel CRISPR-based tool called “CRISPRoff” that can switch off genes in human cells through epigenetic editing without altering the genetic sequence itself. It’s a great tool for controlling gene expression.”.
