Non–Cell-Autonomous Regulation of Interneuron Specification Mediated by Extracellular Vesicles

[Scientific Reports] Scientists identified miRNA that were up-regulated in satellite cell-derived myoblasts treated with stromal derived factor-1 (SDF-1) and/or down-regulated in cells in which the expression of CXCR4 or CXCR7, that is, SDF-1 receptors, was silenced.

[Cell Death & Disease] Investigators revealed that Krüppel-like factor 4 (KLF4) played a critical role in skeletal muscle development and regeneration. Specific knockout of KLF4 in skeletal muscle impaired muscle formation further affecting physical activity and also defected skeletal muscle regeneration.

[Nature Structural & Molecular Biology] Scientists showed that the ability of SS18-SSX to occupy H2AK119ub1-rich regions was an intrinsic property of its SSX C terminus, which could be exploited by fusion to transcriptional regulators beyond SS18.
