The DNA damage response can be initiated in response to a variety of stress signals that are encountered during physiological processes or in response to exogenous cues, such as ionizing radiation or DNA-damaging therapeutic agents. A number of methods have been developed to examine the morphological, biochemical, and molecular changes that take place(More)
Exposure to genotoxic agents, such as irradiation produces DNA damage, the toxicity of which is augmented when the DNA repair is impaired. Poly (ADP-ribose) polymerase (PARP) inhibitors were found to be "synthetic lethal" in cells deficient in BRCA1 and BRCA2 that impair homologous recombination. However, since many tumors, including prostate cancer (PCa)(More)
Macroautophagy is a catabolic process that can mediate cell death or survival. Apo2 ligand (Apo2L)/tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) treatment (TR) is known to induce autophagy. Here we investigated whether SQSTM1/p62 (p62) overexpression, as a marker of autophagic flux, was related to aggressiveness of human prostate cancer(More)
Previously, we showed that inhibition of the protein kinase C β (PKCβ)/AKT pathway augments engagement of the histone deacetylase inhibitor (HDI)-induced apoptosis in lymphoma cells. In the present study, we investigated the cytotoxicity and mechanisms of cell death induced by the delta isoform-specific phosphatidylinositide 3-kinase (PI3K) inhibitor,(More)
UNLABELLED MTOR complex-1(mTORC1) activation occurs frequently in cancers, yet clinical efficacy of rapalogs is limited because of the associated activation of upstream survival pathways. An alternative approach is to inhibit downstream of mTORC1; therefore, acquired resistance to fludarabine (Flu), a purine analogue and antimetabolite chemotherapy, active(More)
Factor IX is a vitamin K-dependent serine protease, which exists as a zymogen in the blood. On activation to factor IXa, by factor XIa or tissue factor-factor VIIa complex, it forms tenase complex with factor VIIIa, in the presence of Ca2+. This tenase complex enzymatically converts factor X to factor Xa, thereby bringing about the coagulation cascade.(More)
