Nkx3.1 functions as para-transcription factor to regulate gene expression and cell proliferation in non-cell autonomous manner.
Nkx3.1 is a homeoprotein transcription factor (TF) that inhibits proliferation of prostate epithelial cells (PECs) and acts as a tumor suppressor for prostate cancer (PCa). Because TFs classically function within the cells that produce them, Nkx3.1-induced growth inhibition was considered to occur in a cell-autonomous manner. We, however, found that Nkx3.1 protein can be secreted from cultured ...
متن کاملStem cell factor Sox2 and its close relative Sox3 have differentiation functions in oligodendrocytes
Neural precursor cells of the ventricular zone give rise to all neurons and glia of the central nervous system and rely for maintenance of their precursor characteristics on the closely related SoxB1 transcription factors Sox1, Sox2 and Sox3. We show in mouse spinal cord that, whereas SoxB1 proteins are usually downregulated upon neuronal specification, they continue to be expressed in glial pr...
متن کاملVEGFA family isoforms regulate spermatogonial stem cell homeostasis in vivo.
The objective of the present study was to investigate vascular endothelial growth factor A (VEGFA) isoform regulation of cell fate decisions of spermatogonial stem cells (SSC) in vivo. The expression pattern and cell-specific distribution of VEGF isoforms, receptors, and coreceptors during testis development postnatal d 1-180 suggest a nonvascular function for VEGF regulation of early germ cell...
متن کاملI-1: Spermatogonial Ontogeny in Mice
Background:Spermatogenesis is maintained by a pool of the spermatogonia. The group formed by As, Apr and Aal is known as undifferentiated type a spermatogonia (Aund). The Aal spermatogonia will differentiate, with no mitotic division, to the differentiating type A1 spermatogonia. The type A1 spermatogonia undergo 6 successive mitotic divisions to yield A2, A3, A4, intermediate-type (In), and ty...
متن کاملThe RXRalpha gene functions in a non-cell-autonomous manner during mouse cardiac morphogenesis.
Germline mutation in mice of the retinoic acid receptor gene RXRalpha results in a proliferative failure of cardiomyocytes, which leads to an underdeveloped ventricular chamber and midgestation lethality. Mutation of the cell cycle regulator N-myc gene also leads to an apparently identical phenotype. In this study, we demonstrate by chimera analysis that the cardiomyocyte phenotype in RXRalpha-...
