In vitro and in vivo androgen regulation of Dendropanax morbiferus leaf extract on late-onset hypogonadism.

Late-onset hypogonadism (LOH) is associated with advancing age and is caused by a deficiency in serum testosterone levels. The aim of this study was to examine the effect of a Dendropanax morbiferus H.Lév.

Cynanchum wilfordii Ameliorates Testosterone-Induced Benign Prostatic Hyperplasia by Regulating 5α-Reductase and Androgen Receptor Activities in a Rat Model.

Benign prostatic hyperplasia (BPH) is characterized by uncontrolled proliferation of the prostate gland. has been reported to improve sexual behavior in male rats. In this study, we investigated the protective effect of an aqueous extract of (CWW) against BPH development in a testosterone-induced BPH rat model.

Proteomic Analysis between U87MG and U343MG-A Cell Lines: Searching for Candidate Proteins for Glioma Invasion.

Background: To investigate the molecular basis for invasion of malignant gliomas, proteomic analysis approach was carried out using two human glioma cell lines, U87MG and U343MG-A that demonstrate different motility and invasiveness in in vitro experiments.

Methods: High-resolution two-dimensional gel electrophoresis and matrix-assisted laser-desorption/ionization time-of-flight mass spectrometry analysis were performed.

Results: Nine distinct protein spots that were recognized with significant alteration between the two cell lines.

Contribution of six flagellin genes to the flagellum biogenesis of Vibrio vulnificus and in vivo invasion.

Vibrio vulnificus is a halophilic pathogenic bacterium that is motile due to the presence of a single polar flagellum. V. vulnificus possesses a total of six flagellin genes organized into two loci (flaFBA and flaCDE).

Effect of Salmonella treatment on an implanted tumor (CT26) in a mouse model.

The use of bacteria has contributed to recent advances in targeted cancer therapy especially for its tumor-specific accumulation and proliferation. In this study, we investigated the molecular events following bacterial therapy using an attenuated Salmonella Typhimurium defective in ppGpp synthesis (ΔppGpp), by analyzing those proteins differentially expressed in tumor tissues from treated and untreated mice. CT26 murine colon cancer cells were implanted in BALB/c mice and allowed to form tumors.

A zinc finger-containing glycine-rich RNA-binding protein, atRZ-1a, has a negative impact on seed germination and seedling growth of Arabidopsis thaliana under salt or drought stress conditions.

Despite the fact that glycine-rich RNA-binding proteins (GRPs) have been implicated in the responses of plants to changing environmental conditions, the reports demonstrating their biological roles are severely limited. Here, we examined the functional roles of a zinc finger-containing GRP, designated atRZ-1a, in Arabidopsis thaliana under drought or salt stress conditions. Transgenic Arabidopsis plants overexpressing atRZ-1a displayed retarded germination and seedling growth compared with the wild-type plants under salt or dehydration stress conditions.
