PURPOSE Most colon cancers show low sensitivity to treatment with oxaliplatin and a specific strategy is needed to overcome this problem. Our approach uses RNA interference to silence the expression of target genes responsible for the development of oxaliplatin resistance. Profile analysis of genes related to the regulation of apoptosis allowed identification of target genes showing the greates...

Apoptosis is a process, which involves a sequence of cellular changes, which ultimately lead to cell death. This programmed cell death is a normal phenomenon required for growth of an organism. Inhibition of apoptosis can result in a number of cancers, inflammatory and autoimmune diseases and viral infections. Inhibitors of apoptosis proteins (IAPs) are a family of structurally and functionally...

BACKGROUND Resveratrol increases nitric oxide (NO) production via increased expression and activation of endothelial-form-NO-synthase (eNOS) in endothelial cells. However, the role of downstream cGMP/protein kinase G (PKG) signaling, a pathway activated by NO/eNOS, in pro- and anti-angiogenic effects of resveratrol is still unclear. MATERIALS AND METHODS Endogenous NO/cGMP/PKG pathway and dow...

Mapatumumab and lexatumumab (targeting death receptor 4 (DR4) and 5 (DR5), respectively) are agonistic TRAIL receptor antibodies that induce apoptosis in a wide range of cancer cells. The potency of mapatumumab and lexatumumab was assessed in mono therapy protocols, and the ability to sensitize for dacarbazine (DTIC) treatment was explored in ten different melanoma cell lines. Our data indicate...

Liver cancer is one of the most common digestive malignancies. Conventional therapies such as surgical resection and chemotherapy are ineffective, and it is rare to achieve complete remission or cure. Application of RNA interference (RNAi) to reduce oncogene expression and thereby change the biology of tumor cells is one of the most important methods in tumor therapy (Sibley et al., 2010). Livi...
