TWO NEW SPECIES OF PARENTIA HARDY, 1935 (DIPTERA: DOLICHOPODIDAE) FROM SOUTH AFRICA


Microtubules oppose cortical actomyosin-driven membrane ingression during C. elegans meiosis I polar body extrusion.

During C.elegans oocyte meiosis I cytokinesis and polar body extrusion, cortical actomyosin is locally remodeled to assemble a contractile ring that forms within and remains part of a much larger and actively contractile cortical actomyosin network.This network both mediates contractile ring dynamics and generates shallow ingressions throughout the

Gene expression regulation by retinoic acid

Over the last quarter century, more Shampoos than 532 genes have been put forward as regulatory targets of retinoic acid.In some cases this control is direct, driven by a liganded heterodimer of retinoid receptors bound to a DNA response element; in others, it is indirect, reflecting the actions of intermediate transcription factors, non-classical
