A sterol regulatory report system of LDLR gene expression in HEK-293 cell line was established.

Objective To establish a sterol regulatory report system of LDLR gene expression in HEK-293 cell line, and apply it for investigation on the lipid-lowering mechanism of Chinese Medicine curcumin.

Effects of antagonism of N-acetyl cysteine on human embryonic kidney cells apoptosis induced by cadmium;

Methods In human embryonic kidney cells (HEK293 cells), the intracellular Ca 2+ concentration ([Ca 2+ ] i) in response to thapsigargin and arachidonic acid were measured by using acetoxymethyl ester of Fura 2 (Fura 2/AM).

Two strains of identified as avian nephropathogenic infectious bronchitis virus (NIBV) produced cytopathic effect(CPE)after 7 passages in chicken embryo kidney cell ,and showed the syncytial type of CPE in which the infected cells coalesced with loss of cell boundaries and revealed multinucleated giant cells.

Studies in vitro with chicken embryo kidney cell (CEKC) cultures and tracheal orgsn cultures (TOC)were attempted to assess the pathogenicity of six strains of infectious bronchitis viruses (IBV) (M41, Connecticut, T,Gray, GIBV and NIBV).

3 was transfected into human embryonic kidney cells(HEK293) with lipofectamine2000.

Comparative study on protective effects of tea polyphenols and vitamin C on anoxia/hypoglycemia injury in cultured human embryonic renal cell 293;
