In the Drosophila ovary, germline stem cells (GSCs) are maintained primarily by bone morphogenetic protein (BMP) ligands produced by the stromal cells of the niche. This signaling represses GSC differentiation by blocking the transcription of the differentiation factor Bam. Remarkably, bam transcription begins only one cell diameter away from the GSC in the(More)
AIM We studied the mechanisms of estrogen/androgen involvement in the induction of NASH by treating Sprague-Dawley (SD) rats fed with a normal or high fat (HF) diet by depriving them of endogenous estrogens/androgens. METHODS Male adult SD rats (n = 10/group) on normal or HF diets were treated for 75 days either with tamoxifen (Tam) or flutamide (Flu) or(More)
