HeLa and 16HBE14o(-) bronchial epithelium cells infected with human rhinovirus serotype 14 (HRV14) were found to exhibit typical apoptotic morphological alterations, such as cell contraction and nuclear condensation. These events coincided with high-molecular-weight DNA fragmentation, activation of caspase-9 and caspase-3 and poly(ADP-ribose) polymerase cleavage. Caspase activation was preceded...

We report here that activation of the caspase-3 apoptotic cascade in spinal cord injury is regulated, in part, by calcineurin-mediated BAD dephosphorylation. BAD, a proapoptotic member of the bcl-2 gene family, is rapidly dephosphorylated after injury, dissociates from 14-3-3 in the cytosol, and translocates to the mitochondria of neurons where it binds to Bcl-x(L). Pretreatment of animals with...

The study aimed to investigate the effects of FSH and eCG on the ovarian and follicular development, expression levels of FSHR and caspase-9 of ovaries in vivo. One hundred and five prepuberty mice were allocated into FSH-1, FSH-2, FSH-3, eCG-1, eCG-2, eCG-3 groups and control group (CG). Mice in FSH-1, FSH-2 and FSH-3 were intramuscularly injected with 5, 10 and 20 IU FSH twice (on day 0 and 4...

Evodiamine (EVO; 8,13,13b,14-tetrahydro-14-methylindolo[2'3'-3,4]pyrido[2,1-b]quinazolin-5-[7H]-one derived from the traditional herbal medicine Evodia rutaecarpa was reported to possess anticancer activity; however, the anticancer mechanism is still unclear. In this study, we investigated the anticancer effects of EVO on human colon COLO205 and HT-29 cells and their potential mechanisms. MTT a...

Adelicate balance exists between cell growth and cell death. In the context of the adult myocardium, inappropriate or inordinate cell loss through an apoptotic process, coupled with the limited regenerative ability of the heart to repair after injury, has been suggested to be a contributing factor to the decline in ventricular performance in patients with heart failure. The ability to prevent o...

introduction: neurodegenerative diseases are progressive disorders that could impair neuronal functions and structures. oxidative stress and mitochondrial dysfunction are involved in the etiology of neurodegenerative diseases such as alzheimer’s disease, parkinson’s disease and etc. gemfibrozil is used as a therapeutic drug for hyperlipidemia. it has been shown that gemfibrozil is neuroprotecti...

objective(s): renal cell carcinoma (rcc) is insensitive to conventional chemotherapy. ginkgetin effectively treats several carcinoma cells. however, little is known about effects of ginkgetin on rcc. in the present study, using 786-o cells, we evaluate whether ginkgetin exerts anticancer effects against rcc. materials and methods: 786-o cells suspended in the medium containing ginkgetin were cu...

Ulcerative colitis (UC) is a common inflammatory disease of the gastrointestinal tract. Traditional Chinese medicine (TCM) has long been used in Asia as treatment for UC and Puerariae Radix (PR) reliable anti-diarrheal therapy. The aims this study were to investigate protective effect PR using dextran sulfate sodium salt (DSS)-induced model mice and identify molecular mechanisms action...

Background and Aim: Smoking has been extensively investigated in oncology, controversial associations with brain tumor incidence have reported. Caspase-3 matrix metalloproteinases (MMPs) belong to an important cascade vasculogenesis. We aim study the smoking impact on these signaling molecules nontumoral rat tissue. Methods Materials/Patients: A total of 60 Wistar rats were divided into two gro...

OBJECTIVE During hypoinsulinemia, when cardiac glucose utilization is impaired, the heart rapidly adapts to using more fatty acids. One means by which this is achieved is through lipoprotein lipase (LPL). We determined the mechanisms by which the heart regulates LPL after acute hypoinsulinemia. RESEARCH DESIGN AND METHODS We used two different doses of streptozocin (55 [D-55] and 100 [D-100] ...
