JNK-dependent cell cycle stalling in G2 promotes survival and senescence-like phenotypes in tissue stress.

abstract：:Forebrain precursor cells are dynamic during early brain development, yet the underlying molecular changes remain elusive. We observed major differences in transcriptional signatures of precursor cells from mouse forebrain at embryonic days E8.5 vs. E10.5 (before vs. after neural tube closure). Genes encoding protein ...
