- An extracellular matrix protein promotes anillin-dependent processes in the Caenorhabditis elegans germline
The extracellular matrix protein Hemicentin (HIM-4) is an extracellular factor that regulates anillin (ANI-1) for germ cell membrane stabilization and contractile ring formation in C. elegans germline cells.
- Inhibition of the deubiquitinase USP8 corrects a Drosophila PINK1 model of mitochondria dysfunction
Aberrant mitochondrial dynamics contribute to disease conditions. Genetic and pharmacological inhibition of USP8 ameliorates mitochondrial phenotypes deriving from loss of function of Drosophila PINK1 and Parkin.
- Competition in the chaperone-client network subordinates cell-cycle entry to growth and stress
Growth and cell-cycle entry compete for multifunctional chaperones subjugating the critical size and proliferation to the growth potential of the cell.
- Mitotic replisome disassembly depends on TRAIP ubiquitin ligase activity
Analysis of the mitotic replisome disassembly pathway in X. laevis egg extract shows that any replisomes retained on chromatin past S-phase are unloaded through formation of K6- and K63-linked ubiquitin chains on Mcm7 by TRAIP ubiquitin ligase and p97/VCP activity.
- Human CST suppresses origin licensing and promotes AND-1/Ctf4 chromatin association
This study suggests a novel role of the telomere-associated human CST complex in suppressing origin licensing, through interactions with MCM, while promoting the recruitment of AND-1 and DNA polymerase alpha for replisome formation.
- A network of human functional gene interactions from knockout fitness screens in cancer cells
The function of human genes can be strongly inferred from their knockout fitness profiles across hundreds of CRISPR screens, illuminating the modular organization of the cell.
- CXXC5 mediates growth plate senescence and is a target for enhancement of longitudinal bone growth
Inhibition of the CXXC5–DVL interaction is a potential therapeutic strategy for height enhancement of children with growth retardation.
- m6A-mRNA methylation regulates cardiac gene expression and cellular growth
This study provides evidence that m6A methylation is dynamically regulated during human and murine cardiac disease and highlights an important role of the m6A methylase Mettl3 in regulating cardiac growth by gene expression control.
- Constitutive STAT5 activation regulates Paneth and Paneth-like cells to control Clostridium difficile colitis
STAT5 controls the intestinal epithelial stem cell niche by regulating Wnt/β-catenin signaling, and lack of active pYSTAT5 induces Clostridium difficile infection. STAT5 may be a transcription factor that restricts niche cell differentiation.
- ROS amplification drives mouse spermatogonial stem cell self-renewal
Although reactive oxygen species (ROS) are required for spermatogonial stem cell (SSC) self-renewal, the mechanism has remained unknown. We show that SSC self-renewal signals activate MAPK14/MAPK7 pathway to induce nuclear translocation of BCL6B and activation of NOX1.
