Basal-cell carcinomas (BCCs) are the commonest human cancer. Insight into their genesis came from identification of mutations in the PATCHED gene (PTCH) in patients with the basal-cell nevus syndrome, a hereditary disease characterized by multiple BCCs and by developmental abnormalities. The binding of Sonic hedgehog (SHH) to its receptor, PTCH, is thought(More)
Physiological evidence suggests that SK-type Ca2+-activated K+ channels participate in ACh-induced hyperpolarization of OHCs (outer hair cells). Based on the sequences published by Kohler et al. [(1996), Science, 273: 1709), we designed degenerated primers recognizing cDNA subunits of rSK1, rSK2 and rSK3. Using this consensus set of primers, we probed by(More)
To study the role of the metabotropic glutamate receptor 8 (mGluR8), mice lacking this receptor were generated by homologous recombination. Homozygous mGluR8-deficient mice are about 8% heavier than their wild-type age-matched controls after reaching 4 weeks of age. This weight difference is not caused by an altered food intake and is not exacerbated by(More)
1. Effects of microinjection of cholecystokinin-8 (CCK-8) into the rat ventral tegmental area were studied on dopamine (DA) release from nucleus accumbens (Acb), using fast cyclic voltammetry and carbon fibre microelectrode. 2. DA release was evoked by electrical stimulation of the medial forebrain bundle (MFB). DA release from Acb was increased with(More)
PURPOSE To detail, by DNA microarrays and cellular structure labeling, the in vitro responses of retinal pigment epithelial (RPE) cells to a nonlethal dose of the oxidant agent hydroquinone (HQ). METHODS The viability of growth-quiescent ARPE-19 cells after treatment with HQ was measured by XTT conversion, (3)H-leucine incorporation, trypan blue(More)
PURPOSE The neonatal Fc receptor (FcRn) has been known to modulate IgG transport and protect against IgG catabolism, resulting in extension of the serum half-life of IgG. The goal of this study was to localize FcRn receptor expression in the rat's eye. METHODS The cornea, retina, conjunctiva, ciliary body and iris, retinal pigment epithelium and choroid,(More)
OBJECTIVE Interleukin-4 (IL-4) can induce macrophages to undergo alternative activation and polarize toward an M2-like or wound healing phenotype. Tumor associated macrophages (TAMs) are thought to assume M2-like properties, and it has been suggested they promote tumor growth and metastasis through effects on the tumor stroma, including extracelluar matrix(More)
