Researchers from TYK Medicines Inc. presented the discovery and preclinical evaluation of a new cyclin-dependent kinase 274/6 (CDK2/4/6) inhibitor, TY-0540, being developed as an anticancer agent.
Researchers from Senelix Co. Ltd. described the preclinical characterization of the novel adiponectin receptor protein 1/2 (ADIPOR1/2) agonist SL-100, which is being developed for the treatment of dry eye disease (DED).
Blocking signaling through the ectodysplasin A2 receptor (EDA2R), a member of the TNF receptor family, protected tumor-bearing mice from developing muscle atrophy associated with cancer cachexia. Upstream and downstream of EDA2R, “we identified two distinct pathways and we demonstrated their involvement in muscle wasting,” Serkan Kir told BioWorld. Kir is a professor at the Koç University Center for Translational Medicine and corresponding author of the paper reporting the findings, which appeared in Nature on May 10, 2023.
A new mouse model of an inherited form of dystonia has shown the spinal cord is the driver of the condition, overturning previous understanding that the movement disorder is caused by disruption of neural circuits in the brain. The connection was demonstrated by selectively deleting torsin family 1 member A (TOR1A), the gene that causes dystonia, in the neurons of the spinal cord only.
The aqueous supernatants resulting from ultracentrifugation of brain samples from patients with Alzheimer’s disease (AD) contain aggregates so far described as soluble oligomers of amyloid-β protein (Aβ), which are responsible for the neurotoxicity underlying AD and thus considered targets to watch in this devastating condition. Now, a group of scientists from Harvard Medical School have determined that these aggregates are in fact insoluble diffusible fibrils with the same atomic structure as plaque fibrils.
The human genome, the sequence that represents the DNA of our species, was built with a single individual as a model. This all-in-one standard didn’t include the gene variations that make us different or explain why some people develop certain diseases. Four simultaneous studies from the Human Pangenome Reference Consortium have published a sequence based on 47 individuals, beginning to capture the genetic diversity that defines humans.
