it is widely thought that bcl-2 family proteins regulate commitment to apoptosis primarily through their capacity to control the permeability of the mitochondrial outer membrane permeabilization (momp) triggers the release of multiple apoptogenic factors into the cytosol and, thereby apoptosis. various bcl-2 family members affect this key event of the apoptotic cascade in different ways, determ...

The objective of this study was to investigate the responses of meat ducks of 15 to 35 d of age to free gossypol (FG) from cottonseed meal (CSM) and to establish the maximum limits of dietary FG concentration based on growth performance, blood parameters, and tissue residues of gossypol. Nine hundred 15-d-old ducks were randomly allocated to 5 treatments with 10 cages/treatment and 18 ducks/cag...

The genus Gossypium is a globally important crop that is used to produce textiles, oil and protein. However, gossypol, which is found in cultivated cottonseed, is toxic to humans and non-ruminant animals. Efforts have been made to breed improved cultivated cotton with lower gossypol content. The delayed gland morphogenesis trait possessed by some Australian wild cotton species may enable the wi...

Kinetic analyses of the mechanisms of patulin- and gossypol-induced cellular toxicity in an immortalized rat hepatocyte cell line were examined using a battery of vital fluorescence bioassays. Intracellular glutathione (GSH) content and intracellular Ca2+ ([Ca2+])i were monitored simultaneously using fluorescent probes requiring uv excitation (351-363 nm); reactive oxygen species (ROS) producti...

Babesia microti is an emerging zoonotic protozoan organism that causes "malaria-like" symptoms that can be fatal in immunocompromised people. Owing to lack of specific therapeutic regiment against the disease, we cloned and characterized B. microti lactate dehydrogenase (BmLDH) as a potential molecular drug receptor. The in vitro kinetic properties of BmLDH enzyme was evaluated using nicotinami...

Adipocytes account for more than 90% of human breast volume and secrete adipocytokines, which play a role in breast cancer development. Among the adipocytokines is leptin, which is secreted mainly by adipocytes and plays a key role in breast cancer development. Leptin expression is up-regulated in both obese and breast cancer patients, and promotes breast cancer cell growth. Exposure to environ...
