Pectin and pectic-oligosaccharides induce apoptosis in in vitro human colonic adenocarcinoma cells.

Background: Dietary fibres have been associated with decreased risk of various cancers, although the mechanisms are unclear. Induction of apoptosis in tumour cells is thought to be an important protective mechanism against colorectal cancer. This work investigates the effects of pectins and pectic-oligosaccharides (POS) on the human colonic adenocarcinoma cell line HT29.

Effects of an antioxidant-rich juice (sea buckthorn) on risk factors for coronary heart disease in humans.

There is increasing evidence to support the hypothesis that free radical-mediated oxidative processes contribute to atherogenesis. More recently the ability of antioxidant nutrients to affect cell response and gene expression has been reported in vitro, providing a novel mechanistic perspective for the biological activity of antioxidants. Sea buckthorn (Hippophaë rhamnoides L.
