Cell colonic

Studies by Hudson et al, (2000) have demonstrated the presence of eight polyphenols in rice bran by using high-pressure liquid chromatography. They are protocatechuic acid, p-coumaric acid, ferulic acid, sinapic aci vanillic acid, caffeic acid, which is a methoxycirmamic acid derivative, and tricin. The effect of these polyphenols on cell viability and on the colony-forming ability of human-derived MDA MB 468 and HBL 100 breast cells, colon-derived SW 480 and human colonic epithelial cells was assessed. These authors concluded that rice bran polyphenols have putative cancer chemopreventive properties.

The core part of a hollow-fiber bioreactor is the hollow-fiber membrane module, also simply known as the cartridge. It consists of a plastic cylinder containing hundreds of semi-permeable capillary tubes, known as hollow fibers. The cells are inoculated in the extracapillary space (ECS). The cells colonize the external surface of the fibers and grow in this region. The culture medium is pumped through the lumen of the fibers, known as the intracapillary space (ICS), as shown in Figure 9.11.

An illustrative experimental example of a cell exposed to an oxidant was carried out by Kirlin et al. (1999). When they used HT29 cells (colon adenocarcinoma) and exposed them to sodium butyrate, it was found that there was an oxidant reaction that caused a drop from 260 to —200 mV in h. The 60 mV decrease resulted in a 100-fold change in protein dithiols disulfide ratio. A correlation was noted between h, GST, and NADPH quinone reductase Kirlin further indicated that the h provides two additional pieces of information (1) in reactions that use GSH as a reductant to maintain protein thiol/disulfides in their reduced form, it is an indicator of the reducing power quantitatively and (2) if the redox state is controlled by a GSH redox couple, it is an indication of the functional state of the protein (Kirlin et al., 1999).
