Rutin inhibits the proliferation of murine leukemia WEHI-3 cells in vivo and promotes immune response in vivo.

Flavonoids are polyphenolic compounds found in various foods of plants. Rutin, one of the flavonoids, had been showed induced apoptosis in cancer cells. There is no available information to address rutin affects murine leukemia cells in vivo.

Curcumin-induced cell cycle arrest and apoptosis in human acute promyelocytic leukemia HL-60 cells via MMP changes and caspase-3 activation.

Curcumin (diferuloylmethane), is a natural product derived from the root of the plant Curcuma longa. For centuries, it has been used as a spice and as a herbal medicine in Chinese populations. Curcumin has been shown to inhibit cell proliferation, cell cycle arrest, cyclooxygenase (COX)-1 and -2 expression and apoptosis in several human cancer cell lines.

Capsaicin induced cell cycle arrest and apoptosis in human esophagus epidermoid carcinoma CE 81T/VGH cells through the elevation of intracellular reactive oxygen species and Ca2+ productions and caspase-3 activation.

Capsaicin (N-vanillyl-8-methyl-1-nonenamide) is found in pungent fruits, especially in red pepper. Many studies have focused on the anticarcinogenic, antimutagenic or chemopreventive activities of capsaicin. However, the effects of capsaicin on human esophagus epidermoid carcinoma cells have never been investigated.

The role of Ca2+ on the DADS-induced apoptosis in mouse-rat hybrid retina ganglion cells (N18).

Diallyl disulfide (DADS), a component of garlic, has been shown to induce growth inhibition and apoptosis in human cancer cell types. The present studies were designed to investigate the effects of DADS on mouse-rat hybrid retina ganglion cells (N18) to better understand its effect on apoptosis and apoptosis-related genes in vitro. Cell viability, cell cycle analysis, reactive oxygen species (ROS), Ca2+ production, mitochondria membrane potential, apoptosis induction, associated gene expression and caspases-3 activity were examined by flow cytometric assay and/or Western blot.
