Reproduction disrupts stem cell homeostasis in testes of aged male Drosophila via an induced microenvironment
Stem cells rely on instructive cues from their environment. Alterations in microenvironments might contribute to tissue dysfunction and disease pathogenesis. Germline stem cells (GSCs) and cyst stem cells (CySC) in [...]
The COP9 signalosome converts temporal hormone signaling to spatial restriction on neural competence.
During development, neural competence is conferred and maintained by integrating spatial and temporal regulations. The Drosophila sensory bristles that detect mechanical and chemical stimulations are arranged in stereotypical positions. [...]
Proneural proteins Achaete and Scute associate with nuclear actin to promote formation of external sensory organs.
Basic helix-loop-helix (bHLH) proneural proteins promote neurogenesis through transcriptional regulation. Although much is known about the tissue-specific regulation of proneural gene expression, how proneural proteins [...]
Smurf-mediated differential proteolysis generates dynamic BMP signaling in germline stem cells during Drosophila testis development
Germline stem cells (GSCs) produce gametes throughout the reproductive life of many animals, and intensive studies have revealed critical roles of BMP signaling [...]
