In studies that give new insights into both developmental biology and the origins of melanoma, investigators at Memorial Sloan-Kettering Cancer Center and Weill Cornell Medical College have identified the activity of chromatin remodeling protein ATAD2 as necessary for cells with the oncogenic mutation V600E to give rise to melanomas.
Investigators at MIT have identified a protein capable of delivering its own mRNA to cells, and engineered that protein to deliver mRNA sequences of their choosing. In a mouse model, the team used their approach to deliver the mRNA for two different proteins.
Researchers from Denali Therapeutics Inc. have identified new functional links between progranulin, lysosomal function, and a subtype of frontotemporal dementia caused by progranulin deficiency (FTD-GRN) that suggest progranulin-mediated FTD could be conceptualized as a lysosomal storage disorder (LSD). They also showed that delivery of their experimental therapeutic PTV:PGRN, also known as DNL-593, reduced cell damage and symptoms of FTD in cell and animal models.
A team of researchers has created peptide-like molecules – "peptoids" – with antiviral properties that could circumvent the naturally occurring antimicrobial peptides' shortcomings.
For most people, neither polyglutamine disorders nor neuromuscular disorders are likely to be among the things they associate with androgen receptor (AR) dysfunction. But the three are indeed linked. And researchers have reported new insights into the nature of those links that could lead to a treatment for spinal and bulbar muscular atrophy, and possibly other disorders linked to AR signaling dysfunction.

When SARS-CoV-2 first emerged in 2020, with respiratory symptoms as the most obvious feature of infection, the most obvious comparison was to influenza. COVID-19, of course, was never just another flu.
Researchers have shown that glucocorticoids, a type of steroid hormones, target both neuroplasticity-related genes and genes related to ciliary function in the brain. However, the effects on the different processes are mediated via different receptors, and in response to different stimuli. A study investigated the specific targets of glucocorticoids, giving new insights into the biological mechanisms of stress adaptations, and how they are linked to neural plasticity.
