Okra (A.esculentus) is an antidiabetic plant that it's beneficial effects on ovarian dysfunction in diabetes condition has not been clarified. The present study was designed to examine the effect of Okra powder on serum oxidant/antioxidant status, ovarian structure and expression of apoptotic/antiapoptotic related genes in ovary of experimentally induced high fat diet diabetic rats. Diabetes wa...
PURPOSE Members of the Bcl-2 family act as master regulators of mitochondrial homeostasis and apoptosis. We analyzed whether ERBB2 influences the prognosis of breast cancer by influencing the proapoptotic versus antiapoptotic balance of Bcl-2 family members. EXPERIMENTAL DESIGN ERBB2-regulated Bcl-2 family members were identified by inducible expression of ERBB2 in MCF-7 breast cancer cells a...
TNF is implicated in the attenuation of neutrophil constitutive apoptosis during sepsis. Antiapoptotic signaling is mediated principally through the TNF receptor-1 (TNFR-1). In adherent neutrophils, when beta-integrin signaling is activated, TNF phosphorylates TNFR-1 and activates prosurvival and antiapoptotic signaling. Previously, we identified the delta-PKC isotype and phosphatidylinositol (...
Apoptosis is a process that can occur normally, such as during tissue remodeling, embryogenesis or abnormally during certain pathologies, such as cancer. The identification of the Bcl2 as well as IAP family members has suggested that excessive inhibition of apoptosis may constitute a common feature of all known human cancers-the ability to influence their onset, progression and outcome. Bcl2 fa...
Increased circulating and tissue levels of plasminogen activator inhibitor 1 (PAI-1) are often present in severe inflammatory states associated with neutrophil activation and accumulation and correlate with poor clinical outcome from many of these conditions. The mechanisms by which PAI-1 contributes to inflammation have not been fully delineated. In the present experiments, we found that addit...
The contribution of basophils in allergic disease and other Th2-type immune responses depends on their persistence at sites of inflammation, but the ligands and molecular pathways supporting basophil survival are largely unknown. The comparison of rates of apoptosis and of the expression of antiapoptotic proteins in different human granulocyte types revealed that basophils have a considerably l...
Sustained engagement of the B-cell receptor (BCR) increases apoptosis resistance in chronic lymphocytic leukemia (CLL) B cells, whereas transient stimulation usually has an opposite effect. The antiapoptotic BCR signal has been associated with prolonged activation of the PI3K/Akt and MEK/ERK pathways, which are key regulators of survival and proliferation in various cell types. To further defin...
PURPOSE In the current study, we investigate the activation of antiapoptotic signaling pathways in response to proteasome inhibitor treatment in pancreatic cancer and evaluate the use of concomitant inhibition of these pathways to augment proteasome inhibitor treatment responses. EXPERIMENTAL DESIGN Pancreatic cancer cell lines and mouse flank xenografts were treated with proteasome inhibitor...
