The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a member of cytokine superfamily, induces apoptosis in a number of tumor cells through the activation of extrinsic apoptotic pathway but shows little or no cytotoxicity toward normal cells. However some tumor cells are inherently
Many anticancer drugs are obtained from phytochemicals and natural products. However, some phytochemicals have mutagenic effects. Safrole, a component of Piper betle inflorescence, has been reported to be a carcinogen. We have previously reported that safrole induced apoptosis in human oral cancer
Safrole, a component of Piper betle inflorescence, is a carcinogen which has been demonstrated to induce apoptosis on human oral cancer HSC-3 cells in vitro and to inhibit HSC-3 cells in xenograft tumor cells in vivo. In our previous study, safrole promoted phagocytosis by macrophages and natural
The deregulated activity of the Bcr-Abl tyrosine kinase provides a rational basis for the development therapeutics in all phases of Chronic Myelogenous Leukemia (CML). Although a well studied imatinib therapy has clinical success against CML, resistance to imatinib due to mutations in the kinase
The role of c-Jun N terminal Kinase (JNK) has been well documented in various cellular stresses where it leads to cell death. Similarly, extracellular signal-regulated kinase (ERK) which was identified as a signalling molecule for survival pathway has been shown recently to be involved in apoptosis
Scientists are constantly searching for phytochemical compounds with anti-cancer activity. In this study, activity of plant extract NPB001-05 from Piper betle was tested on human chronic myelogenous leukemia (CML) xenograft models. NPB001-05 was active when dosed orally (500 mg/kg) once or twice a
Bornyl cis-4-hydroxycinnamate, an active compound isolated from Piper betle stems, was investigated in terms of its effects on A2058 and A375 melanoma cell proliferation and protein expression in this study. We used flow cytometric analysis to examine the early stages of apoptosis induced by bornyl
