Objective: Alcohol use offers social benefits for young adults, but also carries risk of significant negative consequences. Better understanding of processes driving alcohol use for those who experience negative consequences can prevent these harms. These at-risk young adults likely have drinking patterns in common and patterns unique to each individual.

Diplodia sapinea (Fr.) Fuckel is a widespread fungal pathogen affecting conifers worldwide. Infections can lead to severe symptoms, such as shoot blight, canker, tree death, or blue stain in harvested wood, especially in Pinus species.

Cryptosporidiosis is a diarrheal disease caused by the parasite resulting in over 100,000 deaths annually. Here, we present a structure-activity relationship study of the benzoic acid position (R) of pyrazolo[3,4-]pyrimidine lead SLU-2815 (), an inhibitor of parasite phosphodiesterase PDE1, resulting in the discovery of benzoxaborole SLU-10906 () as a benzoic acid bioisostere. Benzoxaborole is 10-fold more potent than against the parasite in a cell-based infection model (EC = 0.

Article Synopsis
  • FSHD is a muscle-wasting disease caused by the misexpression of the DUX4 transcription factor, leading to progressive muscle weakness starting from facial and shoulder muscles and eventually affecting the lower limbs.
  • The study utilized siRNAs to investigate the role of SIX family transcription factors in regulating DUX4 expression in patient-derived FSHD muscle cells, revealing that SIX1, SIX2, and SIX4 are essential for DUX4 induction during muscle differentiation.
  • Additionally, the research indicated that DUX4 actually downregulates SIX RNA levels, suggesting a negative feedback loop in the regulation of these transcription factors in FSHD contexts.

Facioscapulohumeral muscular dystrophy (FSHD) is a degenerative muscle disease caused by loss of epigenetic silencing and ectopic reactivation of the embryonic double homeobox protein 4 gene (DUX4) in skeletal muscle. The p38 MAP kinase inhibitor losmapimod is currently being tested in FSHD clinical trials due to the finding that p38 inhibition suppresses DUX4 expression in preclinical models. However, the role of p38 in regulating DUX4 at different myogenic stages has not been investigated.
