An analysis of more than 1,000 small molecules has identified dozens of compounds that could be effective to treat Marfan syndrome (MFS), an inherited disorder affecting connective tissue, primarily in the heart and blood vessels, the skeleton, and the eyes. In particular, the researchers from Cambridge University found that glycogen synthase kinase-3β (GSK-3β) could be a target to develop new therapies based on its inhibition.

Bacterial abortive infection is a defense mechanism by which an infected bacterial cell enters dormancy or dies to limit phage replication and protect the clonal population. Recent studies observed that CRISPR RNA-guided adaptive immune systems that target RNA also cause abortive-infection phenotypes by activating indiscriminate nucleases.

Myrtelle Inc. and Raaven Therapeutics AB have partnered on the development of novel recombinant adeno-associated virus (rAAV) vectors to advance gene therapy treatments for diseases of the central nervous system (CNS) in which myelin is affected.

Kronos Bio Inc. has entered into a discovery collaboration in the field of oncology with Genentech Inc., a member of the Roche Group, focused on discovering and developing small-molecule drugs that modulate transcription factor targets selected by Genentech.

Esperovax Inc. and Ginkgo Bioworks Inc. have established a partnership to develop circular RNAs (circRNAs) for a variety of therapeutic applications.

CRISPR, or clustered regularly interspaced palindromic repeats, is transforming biomedical research, and making rapid inroads into the clinic, with its ability to easily target specific DNA and RNA sequences. CRISPR itself is made of RNA. It recognizes target sequences and delivers CRISPR-associated (Cas) proteins, nucleases that cut the target sequence. In two papers published online in Nature on Jan. 4, 2023, researchers have demonstrated that a recently discovered type of Cas protein, Cas12a2, can degrade double-stranded DNA when its associated CRISPR guide RNA recognizes its target sequence.

Tucked into the 4,155-page, $1.7 trillion spending bill for fiscal 2023 that U.S. President Joe Biden signed into law Dec. 23 is a small provision that may have outsized impact on future biosimilar and other drug development. Championed by lawmakers on both sides of the political spectrum, the provision modernizes the data that can be used to support drug development, including alternatives to animal studies.

Ice, juice, the exact measure of liquor, a few drops of Angostura... What goes into a good New Year’s Eve cocktail? According to researchers working on vaccines for the most elusive viruses, it will be time soon to toast next-generation vaccines. If 2020 was the year of the COVID-19 pandemic, and in 2021 the year of mRNA vaccinations, 2022 brought polyvalent designs of antigens, evaluated highly neutralizing antibodies, and fine-tuned mRNA technology against SARS-CoV-2, HIV and the flu.
