Abstract:
:The analgesic buprenorphine hydrochloride (Bph) induced apoptosis-like cell death in the caspase-3-deficient human breast cancer cell line, MCF-7. This apoptosis-like cell death activated key molecules in the mitochondrial apoptotic pathway: cytochrome c, caspase-9, caspase-7, and caspase-6. Bph caused the release of fluorescent protein from the mitochondria of MCF-7 cells transfected with the pDsRed2-Mito-vector in a time-dependent manner, suggesting disruption of the mitochondrial membrane. Zn(2+) as high as 2 mM did not inhibit the DNase that took part in this apoptosis. Thus, this unidentified DNase might resemble other DNases involved in apoptosis-like cell death whose activity is not inhibited by zinc ion.

LIFE SCIENCES文献大全abstract:AIMS:Constant development of chemotherapeutic strategies has considerably improved the efficiency of tumor treatment. However, adverse effects of chemotherapeutics enforce premature treatment cessation, which leads to the tumor recurrence and accelerated death of oncologic patients.
