Hepatosellüler karsinom (HCC), kansere bağlı ölüm sıralamasında ikinci sırada yer alır ve dünya genelinde sıklığı artmaktadır. Papain proteolitik bir enzimdir potansiyel antikanser ajanıdır. Çalışmanın amacı, papainin insan hepatom HepG2 hücre hattındaki sitotoksik etkisinin apoptoz üzerinden değerlendirilmesidir. Papainin sitotoksisitesi MTT yöntemi ile belirlendi. uygulanan hücrelerinin morfo...

Abstract Many drugs have been developed for anticancer chemotherapy. However, more anti-cancer should be from potential chemicals to circumvent the disadvantages of existing drugs. Most induce apoptosis in cancer cells. This study tested efficiency a new chemical, piperazine derivative 1-[2-(Allylthio) benzoyl]-4-(4-methoxyphenyl) (CB01), on glioblastoma (U87) and cervix (HeLa) CB01 was highly ...

We have previously shown that caspase-2 (Nedd-2) is required for apoptosis induced by withdrawal of trophic support from PC12 cells and sympathetic neurons. Here, we examine the relationship of caspase-2 processing and cell death to induction of caspase-3 (CPP32)-like activity in PC12 cells. Caspase-2 processing, at a site tentatively identified as D333, led to the formation of an N-terminal 37...

Alternative splicing of caspase-3 produces a short isoform caspase-3s that antagonizes caspase-3 apoptotic activity. However, the mechanism of apoptosis inhibition by caspase-3s remains unknown. Here we show that exogenous caspase-3 sensitizes MCF-7 and HBL100 breast cancers cells to chemotherapeutic treatments such as etoposide and methotrexate whereas co-transfection with caspase-3s strongly ...
