Abstract Apoptosis and senescence are two mutually exclusive cell fate programs that can be activated by stress. The factors instruct cells to enter into or apoptosis not fully understood, but both regulated the stress kinase p38α. Using an inducible system specifically activates this pathway, we show sustained p38α activation suffices trigger massive autophagosome formation enhance basal autophagic flux. This requires concurrent effect of increased mitochondrial reactive oxygen species...
ABSTRACT The first hematopoietic stem and progenitor cells (HSPCs) emerge in the Aorta-Gonad-Mesonephros (AGM) region of mid-gestation mouse embryo. However, precise nature their supportive mesenchymal microenvironment remains largely unexplored. Here, we profiled transcriptomes laser micro-dissected aortic tissues at three developmental stages individual AGM cells. Computational analyses allowed identification several cell subpopulations within E11.5 mesenchyme, with presence a yet...
p38α (encoded by MAPK14) is a protein kinase that regulates cellular responses to almost all types of environmental and intracellular stresses. Upon activation, phosphorylates many substrates both in the cytoplasm nucleus, allowing this pathway regulate wide variety processes. While role stress response has been widely investigated, its implication cell homeostasis less understood. To investigate signaling networks regulated proliferating cancer cells, we performed quantitative proteomic...

Upon activation, phosphorylates many substrates both in the cytoplasm nucleus, allowing this pathway regulate wide variety processes. While role stress response has been widely investigated, its implication cell homeostasis less understood.
