Alltrna Inc. has presented new preclinical data on the company’s first transfer RNA (tRNA) development candidate, AP-003.

Researchers from E-Therapeutics plc presented preclinical data for ETX-312, a GalNAc-conjugated short interfering RNA (siRNA), produced using the Galomic platform and being developed for the treatment of metabolic dysfunction-associated steatohepatitis (MASH).

A ketone body, a molecule derived from the metabolism of acids to obtain energy when glucose is not available, could become an effective ally in treating Alzheimer’s or preventing the effects of aging on the brain. A group of scientists at the Buck Institute for Research on Aging have studied the role of β-hydroxybutyrate (βHB) as a signaling metabolite of misfolded proteins by interacting with them and altering their solubility, a mechanism that allows their elimination, as observed in preclinical models.

A U.K. study has uncovered distinctive genetic drivers of type 2 diabetes in South Asians that lead to faster development of complications, the need for earlier insulin replacement therapy and a weaker response to some widely prescribed drugs. That points to the need to refine care pathways. But in addition, the research provides a potent illustration of how the under-representation in genomics databases of people who are not of white European origin can skew results and be a source of discrimination.

Potent siRNAs against B4GALT1 were designed in silico and screened in vitro (Huh7 cells, primary mouse, human hepatocytes) as well as in vivo (C57BL/6 mice) for the selection of a lead Galomic siRNA.

Researchers at the University of Copenhagen have identified a signaling pathway that simultaneously increased energy expenditure and decreased food intake. In both human and primate studies, agonists of the tachykinin NK2 receptor (NK2R) led to both decreased food intake and increased energy expenditure. And in behavioral tests, they were not aversive, suggesting they do not cause the nausea that is a major side effect of GLP-1 agonists.
