RNA-sequencing analysis of wild-type, mych mut and mycb mut fish revealed that Mycb and Mych regulate ∼40% and ∼16%, respectively, of the genes contributing to the regeneration-associated...

...Jimei Xu; Yanwen Jiang; Ryan Sherrard; Kyoko Ikegami; Barbara Conradt ABSTRACT During C. elegans development, 1090 somatic cells are generated, of which 959 survive and 131 die, many through apoptosis. We present evidence that PUF-8, a C. elegans ortholog of the mammalian RNA-binding proteins PUM1...

This pathway, coupled with apoptosis, the cleavage division pattern and cell cycle duration controlling the size of the embryonic stem cell...

Here, we show that this process is apoptosis dependent, and clustered apoptosis, groove formation, and wounding sensitize EGFR mutant epithelia...

In this study, we report that Fra is required in the Drosophila female germline for the progression of egg chambers through mid...

... is largely unknown. Here, we show that Exosc10, a RNA exonuclease subunit of the RNA exosome complex, is indispensable for forebrain development. We report that cortical cells undergo overt apoptosis, culminating in cortical agenesis upon conditional deletion of Exosc10 in mouse cortex. Mechanistically...

... that is suppressed by Hx. Interestingly, GCs with lower expression of GDF9/BMP15 receptors appear to be more sensitive to Hx-induced G2/M arrest and become easily detached from the follicular wall. Importantly, Hx-mediated inhibition of G2/M progression instigates GC apoptosis, which is ameliorated in the presence...

... analysis implicates p53 signaling; moreover, p53 ablation in Magoh haploinsufficient progenitors rescues apoptosis, completely recovering interneuron number. In striking contrast, in Magoh homozygotes, p53 loss fails to rescue interneuron number and mitotic delay, further implicating mitotic defects...

Loss of LTK in the cranial neural crest impairs migration and results in increased levels of apoptosis. Conversely, midkine, previously proposed as a ligand for ALK...

A single INP can make both astrocyte-like and ensheathing glia, which co-occupy a relatively restrictive subdomain. Blocking apoptosis uncovers further lineage distinctions in the specification...

It is known that mutation of Zeb1 , one of the retinoblastoma 1 (Rb1) target genes, results in a decrease in the number of immature T cells in mice. E2F1, an RB1-interacting protein, has been shown to regulate mature T cell development by interfering...
