Elephantopus scaber Linn. was used traditionally for treating various diseases. Previous studies found the cytotoxicity of this herb against different cell lines. This study aimed to determine the effectiveness of the ethanolic extract of E.scaber in inducing apoptosis by observing itseffect on caspase cascade. This ethanolic extract was obtained by maceration method using 96% ethanol. It was f...

Since publication of our article [1], we have realised that the legend of Figure one needs to be corrected and should read as follows: “Photomicrograph of Gc-5spg and Gc-6spg stained with an anti-activated caspase 3 antibody and counterstained with Haemaluin as described in Materials and Methods. A, Gc-5spg culture treated with 200 uM CAP for 24 h B, Gc-6spg culture treated with 250 uM CAP duri...

Photodynamic therapy (PDT) is an innovative and perspective antineoplastic therapy. Tetra-α-(4-carboxyphenoxy) phthalocyanine zinc (TαPcZn)-mediated PDT (TαPcZn-PDT) has shown antitumor activity in some tumor cells, but the manner which caspase-1 involved regulation of apoptosis pyroptosis TαPcZn-PDT-treated breast cancer MCF-7 cells unclear. Therefore, effects TαPcZn-PDT on cytotoxicity, cell ...

caspase-3, one of the dominant effectors caspases, is activated in almost every model of apoptosis with various signaling pathways. hence, inhibition of caspase-3 has become an attractive target in the treatment of neurodegenerative diseases. caspase-3 inhibitory activities of some 1,2-benzisothiazol-3-one derivatives were modeled by quantitative structure–activity relationship (qsar) using ste...

background: in this study, the protective effect of thymoquinone (tq) and nigella sativa seeds oil (nso) was evaluated against oxidative damages induced by ethanol in rats. methods: animals were treated with ethanol 40% daily by gavages once a day for 4 weeks. nso and tq were injected intraperitoneal once a day for 4 weeks. the histopathological examination of liver, kidney, brain and heart was...

Apoptosis of murine and human macrophages induced by group B Streptococcus agalactiae (GBS) is likely an important virulence mechanism that is used by the bacteria to suppress the host immune response and to persist at sites of infection. The mechanisms by which GBS induces apoptosis are, however, largely unknown. In this study, we report that in murine macrophages GBS induces unique changes in...

background: metformin is used to lower blood sugar in patients with type ii diabetes. recent research showed that metformin has effects on cancer cell growth. studies show that metformin can induce apoptosis in certain cancer cell lines. in this study, we examined the effect of metformin on apoptosis in the t47d breast cancer cell line. methods : the t47d breast cancer cell line was selected an...

the pathogenesis of equine grass sickness (egs) has not fully understood. a better understanding of the exact pathogenesis of diseases can help to make an accurate diagnosis. previous studies reported some pathological damage of neuronal cells in egs patients. in this study, primarily cytotoxicity of serum from three clinically egs-diagnosed horses on pc12 tet-off (pto) cells was assessed. subs...
