Adipose‑derived mesenchymal stem cell‑facilitated TRAIL expression in melanoma treatment in vitro.

Adipose-derived stem cells (ADSCs) may be useful as an efficient vehicle in cell-based gene therapy of human diseases due to their ability to migrate to disease lesions. This study investigated the ability of ADSC‑harbored human tumor necrosis factor‑related apoptosis‑inducing ligand (TRAIL) cDNA to facilitate TRAIL expression and induce A375 melanoma cell apoptosis as observed using a Transwell co‑culture system. A cell migration assay was used to observe ADSC migration ability.

[Purification and identification of recombinant varicella-zoster virus glycoprotein E].

Objective: To purify and identify recombinant Varicella-Zoster Virus Glycoprotein E.

Methods: The recombinant plasmid pGEX-VZVgE was induced by isopropyl-beta-D-thiogalactoside (IPTG), the fusion protein was purified with affinity chromatography column; then the purified fusion protein was cleaved by thrombin, and the product's antigenicity was examined by Western blot.

Results: The product of pGEX-VZVgE induced by IPTG was separated from the mixture proteins by the affinity chromatography column, the expressed fusion protein's relative molecular mass was about 98 x 10(3).
