Regulation of electrogenic anion secretion in normal and cystic fibrosis gallbladder mucosa.

Fluid and ion transport across biliary epithelium contributes to bile flow. Alterations of this function may explain hepatobiliary complications in cystic fibrosis (CF). We investigated electrogenic anion transport across intact non-CF and CF human gallbladder mucosa in Ussing-type chambers.

Sheep gene mapping: synteny between COL2A1 and the LDHB-PEPB-TPI-GAPD-LALBA-IGF1 group.

DNA extracted from 21 hamster-sheep hybrid cell lines was subjected, after Southern blotting, to hybridization with a type-II alpha 1 collagen genomic probe (COL2A1). The corresponding locus was found to be syntenic with the LDHB-PEPB-TPI-GAPD-LALBA-IGF1 group in sheep.
