Wild Type p53 Gene Transfer Increases Chemosensitivity and Apoptotic Response of PANC-1 Pancreatic Tumor Cell Line
The effect of p53 gene therapy on chemosensitivity and apoptotic response of PANC-1 tumor cells, which express high amount of mutant p53, to cancer chemotherapeutic agents of Etoposide and Doxorubicin was investigated. Comparison of the chemosensitivity of PANC-1 cells to its wild type p53 transfectants showed that wt-p53 expressing transfectants are more sensitive to both Etoposide and Doxorub...
متن کاملHypoxia-Inducible Factor 1α Determines Gastric Cancer Chemosensitivity via Modulation of p53 and NF-κB
BACKGROUND Reduced chemosensitivity of solid cancer cells represents a pivotal obstacle in clinical oncology. Hence, the molecular characterization of pathways regulating chemosensitivity is a central prerequisite to improve cancer therapy. The hypoxia-inducible factor HIF-1alpha has been linked to chemosensitivity while the underlying molecular mechanisms remain largely elusive. Therefore, we ...
متن کاملThe p53 family protein p73 provides new insights into cancer chemosensitivity and targeting.
The p53 tumor suppressor is part of a small family of related proteins that includes two other members, p73 and p63. Interest in the p53 family members, their functions and their complex interactions and regulation, has steadily grown over recent years and does not show signs of waning. p73 is a major determinant of chemosensitivity in humans, and mutant p53 proteins carrying specific polymorph...
متن کاملEffects of p53-expressing adenovirus on the chemosensitivity and differentiation of anaplastic thyroid cancer cells.
We investigated the p53 status and the ability of exogenous wildtype (wt) p53 to affect chemosensitivity in three anaplastic thyroid carcinoma cell lines (BHT-101, SW-1736, and KAT-4). All three cell lines had nonfunctional p53. Treatment with mitomycin C or adriamycin did not result in accumulation of p53 or induction of p21WAF1/CIP1 or Mdm-2 and did not cause Rb dephosphorylation. BHT-101 and...
متن کاملDecoy receptor 2 (DcR2) is a p53 target gene and regulates chemosensitivity.
Decoy receptor 2 (DcR2) is one of the tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) receptors and suppresses TRAIL-induced apoptosis. Its expression, like the other three TRAIL receptors (i.e., DR4, DR5, and DcR1), is regulated by p53. Here, we report that DcR2 is a p53 target gene and regulates chemosensitivity. In this study, we identified a p53-binding site (p53BS) in the f...
