Abstract Cancer is the leading cause of death worldwide. Current anticancer drugs involve various toxic side effects; efforts are ongoing to develop new anticancer agents especially from the screening of natural compounds. Present study investigated cytotoxic effects and mode of cell death induced by the Caspian cobra venom in some human cancer cell lines. Cytotoxic effects of snake venom toxin...

Objective (s): Gravity could affect some system features and perform directly as an organizing field factor. Recent investigations have examined the titanium dioxide nanoparticles (TiO2 NPs) in biomedical applications, mostly in the cancer treatment field. This study aimed to evaluate the effects of simulated microgravity combined with TiO2 NPs in MDA-MB-231 cells proliferation for the first tim...

Androgens stimulate myogenesis, but we do not know what cell types within human skeletal muscle express the androgen receptor (AR) protein and are the target of androgen action. Because testosterone promotes the commitment of pluripotent, mesenchymal cells into myogenic lineage, we hypothesized that AR would be expressed in mesenchymal precursor cells in the skeletal muscle. AR expression was e...

We have developed a novel reporter for the analysis of gene expression using a Drosophila prophenoloxidase (proPO) gene. We have expressed proPO in transgenic flies using the GAL4-UAS system and characterized ectopic expression in imaginal discs. proPO staining is fast and robust, requiring only inexpensive reagents, and performs similarly to β-galactosidase (β-gal) staining. Double staining us...

Adult skeletal muscle regeneration is orchestrated by a specialized population of adult stem cells called satellite cells, which are localized between the basal lamina and the plasma membrane of myofibers. The process of satellite cell-activation, proliferation, and subsequent differentiation that occurs during muscle regeneration can be recapitulated ex vivo by isolation of single myofibers fr...

Nihill, M. R., Wilson, D. S., and Hugh-Jones, K. (1970). Archives of Disease in Childhood, 45, 122. Generalized glycogenosis type II (Pompe's disease). The characteristic clinical features of 2 cases of Pompe's disease are presented, namely, signs of a cardiomyopathy with skeletal hypotonia and a characteristic ECG with a short PR interval and high voltage QRS complexes. Glycogen storage diseas...

Hyperhomocysteinemia (HHcy) is known for causing inflammation and vascular remodeling, particularly through production of reactive oxygen species (ROS) and matrix metalloproteinase-9 (MMP-9) activation. Although its effect on the skeletal muscle is unclear, HHcy can cause skeletal muscle weakness and functional impairment by induction of inflammatory mediators and macrophage mediated injury. Ex...

Myostatin, a member of the transforming growth factor-beta superfamily, is a negative regulator of skeletal muscle growth. Cattle with mutations that inactivate myostatin exhibit a remarkable increase in mass of skeletal muscle called double muscling that is accompanied by an equally remarkable decrease in carcass fat. Although a mouse knockout model has been created which results in mice with ...
