To investigate the cell-killing effect and its possible mechanism of rClone30-hDR5 in combination with TRAIL on human hepatic carcinoma (HCC) cell line, first of all, recombinant plasmid pee12.4-hDR5 was introduced into HepG2 cells by liposome transfection. After five rounds of screening by flow cytometry, HepG2 cells expressing high levels of DR5 on cell surface were isolated.

Previous studies proposed that the synergistic effect of fibroblast growth factor-21 (FGF-21) and insulin may be due to the improvement of insulin sensitivity by FGF-21. However, there is no experimental evidence to support this. This study was designed to elucidate the mechanism of synergistic effect of FGF-21 and insulin in the regulation of glucose metabolism.

In order to enhance the antitumor efficacy of recombinant Newcastle disease virus, rNDV-IL15 was rescued in this study. Recombinant plasmid prNDV-IL15 was constructed, and BHK21 cells were transfected with the recombinant plasmid. Finally, the recombinant Newcastle disease virus rNDV-IL15 was successfully rescued.

Aim: To optimize antibody affinity of a humanized anti-hIL17A single-chain Fv (scFV) antibody through error-prone polymerase chain reaction (PCR) so as to develop a therapeutic humanized antibody for the treatment of rheumatoid arthritis (RA).

Methods: Variable regions of heavy chain and light chain were subjected to random mutation by error-prone PCR and a scFv library was constructed by overlapping PCR. The library was screened for improved mutants by the bacterial inner membrane display technique and flow cytometry (FCM).
