Expression of human pancreatic polypeptide in heterologous cell lines.

Expression of Human Pancreatic Polypeptide in Heterologous

Pancreatic polypeptide (PP) is initially synthesized as a larger precursor that requires post-translational processing to produce the biologically active hexatriacontapeptide. These steps include tryptic cleavage at paired basic residues, their subsequent removal by a carboxypeptidase B-like enzyme, and formation of a carboxyl-terminal amide moiety via the action of peptidyl-glycyl a-amidating ...

The Expression of Heme Oxygenase-1 in Human-Derived Cancer Cell Lines

Background: Heme oxygenase-1 (HO-1) is a cytoprotective and antiapoptotic enzyme, which has been involved in maintaining cellular homeostasis, and plays an important protective role by modulating oxidative injury. Up-regulation of (HO-1) has contributed to tumorogenicity of some cancers. In this study we investigated the expression pattern of the HO-1, in five different human-derived cancer cel...

ZJRMS 2015 Sep; X(X): XX-XX Background: Genes are involved in the control of stem cell self-renewal as a new class of molecular markers of cancer. In this study, the expression of Oct4, Nanog and Sox2 in cell lines MIA Paca-2, PA-TU-8902 and AsPC-1 and pancreatic cancer tissue were examined. M...

Induction of apoptosis in human tumor cell lines by platelets

Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...
