Article Synopsis
- Autocrine motility factor (AMF), a version of phosphoglucose isomerase secreted by tumors, promotes cancer cell growth, survival, and movement, as well as angiogenesis.
- A study showed that inhibiting AMF with targeted antibodies can reduce cancer growth, demonstrated by experiments that tested cancer cell movement and tumor weight in mice.
- The findings suggest that a specific antibody against AMF could serve as a potential treatment for gastric cancer, showing similar effectiveness to existing cancer antibodies like trastuzumab.
A long-lasting recombinant human albumin-linker-erythropoietin (EPO) is a human albumin gene fused to the N-terminal of EPO with a (GGSGG)(n)-repeated linker inserted between albumin and EPO. Albumin-EPO fusion genes were co-transfected with the dhfr gene. Albumin-EPO fusion protein has three kinds of sub-types (IALE, AD2LE, AD1LE).

Gankyrin binds to Mdm2, which results in accelerated ubiquitylation via degradation of p53, and it also plays an important role in cell proliferation. However, little is known about the relationships between p53 levels, cell proliferation, and gankyrin over-expression.

Methods: HepG2 and Huh7 cells were treated with NS-398. Its effects on cell viability, cell proliferation, cell cycles, and gene expression were respectively evaluated by water-soluble tetrazolium salt (WST-1) assay, 4'-6-diamidino-2-phenylindole (DAPI) staining, flow cytometer analysis, and Western blotting, with dimethyl sulfoxide (DMSO) as positive control.
Liver cirrhosis is one of the major complications of hepatitis C virus (HCV) infection, but the mechanisms underlying HCV-related fibrogenesis are still not clear. Although the roles of HCV core protein remain poorly understood, it is supposed to play an important role in the regulation of cellular growth and hepatocarcinogenesis. The aim of this study was to examine the role of HCV core protein on the hepatic fibrogenesis.

In the present study, we investigated whether or not HCV core protein is directly related to liver fibrogenesis through stimulation of hepatic stellate cells (HSC).
Methods: Human and rat HSC were isolated and we established an in vitro co-culture system of a stable HepG2-HCV core cell line which was transfected with HCV core gene and primary HSC.
