The chorda tympani nerve (CT), one of three nerves that convey gustatory information to the nucleus of the solitary tract (NTS), displays terminal field reorganization after postnatal day 15 in the rat. Aiming to gain insight into mechanisms of this phenomenon, CT axon projection field and terminal morphology in NTS subdivisions were examined using tract tracing, light microscopy, and immunoele...
Mechanisms of tissue stem cell (SC) quiescence control are important for normal homeostasis and for preventing cancer. Cyclin-dependent kinase inhibitors (CDKis) are known inhibitors of cell cycle progression. We document CDKis expression in vivo during hair follicle stem cell (HFSC) homeostasis and find p21 (cyclin-dependent kinase inhibitor 1a, Cdkn1a), p57, and p15 up-regulated at quiescence...
Transcription elongation is stimulated by positive transcription elongation factor b (P-TEFb), for which activity is repressed in the 7SK small nuclear ribonucleoprotein (7SK snRNP) complex. We show here a critical role of 7SK snRNP in growth control of primordial germ cells (PGCs). The expression of p15(INK4b), a cyclin-dependent kinase inhibitor (CDKI) gene, in PGCs is selectively activated b...
Humoral immune response to ectropic leukemia viruses in AKR and C57BL/6 mice was controlled by a gene that mapped in linkage group IX. Mice of the AKR strain had an immune nonresponsive allele of this gene, whereas mice of the C57BL/6 strain had an immune responsive allele. Antibody against murine leukemia virus (MuLV) reacted primarily with p15 protein of the viral envelope. It was concluded t...
