'The endothelin (ET) family of peptides acts via two subtypes of guanine nucleotide-binding regulatory protein (G protein)-coupled receptors termed ETA and ETB. ET-1 stimulated cAMP formation in Chinese hamster ovary (CHO) cells stably expressing human wild-type ETA (CHO/hETA cells) while it inhibited cAMP formation in CHO cells expressing human wild-type ...

Molecular cloning and functional analysis of the promoter of the human squalene synthase gene.
Authors: Guan G; Jiang G; Koch R L; Shechter I;
Journal:J Biol Chem
PubMed ID:7665618
'We have cloned and characterized the 5''-flanking region of the gene encoding human squalene synthase. We report here the promoter activity of successively 5''-truncated sections of a 1 kilobase of this region by fusing it to the coding region of a luciferase reporter gene. DNA segments of 200 base pairs ... More
Identification of a minimum enhancer sequence for the type II collagen gene reveals several core sequence motifs in common with the link protein gene.

'The type II collagen gene (Col2a1) is expressed primarily in chondrocytes. Transcription of Col2a1 is mediated by cell-specific regulatory elements located within the promoter and first intron. Here, we map a minimal enhancer and identify elements that determine cartilage-specific Col2a1 expression by analyzing the activity of a series of chimeric ... More

'Interferon gamma (IFN-gamma) signals through a multimeric receptor complex consisting of two different chains: the IFN-gamma receptor binding subunit (IFN-gamma R, IFN-gamma R1), and a transmembrane accessory factor (AF-1, IFN-gamma R2) necessary for signal transduction. Using cell lines expressing different cloned components of the IFN-gamma receptor complex, we examined the ... More
Isolation, characterization, and differentiation of human multipotent dermal stem cells.

PubMed ID:23483399
Skin, as the body's largest organ, has been extensively used to study adult stem cells. Most previous skin-related studies have focused on stem cells isolated from hair follicles and from keratinocytes. Here we present a protocol to isolate multipotent neural crest stem-like dermis-derived stem cells (termed dermal stem cells or ... More
