Abstract
During development, progenitor cell survival is essential for proper tissue functions, but the underlying mechanisms are not fully understood. Here we show that ERCC6L2, a member of the Snf2 family of helicase-like proteins, plays an essential role in the survival of developing chick neural cells. ERCC6L2 expression is induced by the Sonic Hedgehog (Shh) signaling molecule by a mechanism similar to that of the known Shh target genes Ptch1 and Gli1. ERCC6L2 blocks programmed cell death induced by Shh inhibition and this inhibition is independent of neural tube patterning. ERCC6L2 knockdown by siRNA resulted in the aberrant appearance of apoptotic cells. Furthermore, ERCC6L2 cooperates with the Shh signal and plays an essential role in the induction of the anti-apoptotic factor Bcl-2. Taken together, ERCC6L2 acts as a key factor in ensuring the survival of neural progenitor cells.
期刊介绍：
Development Growth & Differentiation (DGD) publishes three types of articles: original, resource, and review papers.
Original papers are on any subjects having a context in development, growth, and differentiation processes in animals, plants, and microorganisms, dealing with molecular, genetic, cellular and organismal phenomena including metamorphosis and regeneration, while using experimental, theoretical, and bioinformatic approaches. Papers on other related fields are also welcome, such as stem cell biology, genomics, neuroscience, Evodevo, Ecodevo, and medical science as well as related methodology (new or revised techniques) and bioresources.
Resource papers describe a dataset, such as whole genome sequences and expressed sequence tags (ESTs), with some biological insights, which should be valuable for studying the subjects as mentioned above.
Submission of review papers is also encouraged, especially those providing a new scope based on the authors’ own study, or a summarization of their study series.
