Vitamin E succinate (VES) and all-trans-retinoic acid (RA) were determined to be growth inhibitory for B lymphoma cells in vitro. RL, an Epstein-Barr virus-negative human cell line, was growth suppressed 87% with VES (5 micrograms/ml) and 58% with RA (10(-6) M); both agents blocked the cells in G1 of the cell cycle. The antiproliferative effect of VES seems(More)
The effect of synthetic human calcitonin gene-related peptide (hCGRP) on the isolated and electrically driven left atria of rats were investigated. The peptide at concentrations of 3 X 10(-9)-3 X 10(-7) M produced positive inotropic effects on the left atria in a dose-dependent manner. Verapamil (10(-5) M) and adenosine (10(-4) M) reduced the positive(More)
A rat islet amyloid polypeptide (amylin), 37-residue peptide amide was synthesized by the Fmoc-based solid phase method and the biological activity of synthetic rat amylin on exocrine pancreas was evaluated for the first time in conscious rat. Amylin (1, 10 nmol/kg/h) stimulated pancreatic exocrine secretion and plasma gastrin concentration. CR-1409, a CCK(More)
Memory B cells (MBCs) and long-lived plasma cells (LLPCs) are responsible for immunological "memory", which can last for many years. The long-term survival niche for LLPCs in the bone marrow is well characterized; however, the corresponding niche for MBCs is unclear. BILL-cadherin/cadherin-17 (CDH17) is the only member of the cadherin superfamily that is(More)
Effects of synthetic human pancreastatin-52 and human pancreastatin-29 on pancreatic secretion and blood flow were examined in rats and dogs. Synthetic human pancreastatin-52 and human pancreastatin-29 were equally potent in suppressing the release of amylase stimulated by cholecystokinin in rats in vivo. However, neither human pancreastatin-52 nor human(More)
Effects of synthetic rat pancreastatin C-terminal fragment on both exocrine and endocrine pancreatic functions were examined in rats, in vivo and in vitro. Pancreastatin (20, 100 pmol, 1 nmol/kg/h) significantly inhibited CCK-8-stimulated pancreatic juice flow and protein output in a dose-related manner, in vivo. The inhibitory effect on bicarbonate output(More)
