Description
Winged bean (WB), Psophocarpus tetragonolobus, is a tropical legume, the potential of which is not yet been understood. We found that a 5 week-oral administration of WB seed extract inhibited wrinkle formation induced by repeated tape stripping (TS), which is a model of lichenification in human chronic eczematous dermatitis.

Lactic acid bacteria confer a variety of health benefits. Here we investigate the mechanisms by which Lactobacillus brevis KB290 enhances cell-mediated cytotoxic activity. We fed a diet containing KB290 (3 10^9 colony-forming units/g) , or potato starch, to 9-week-old female BALB/c mice for 1, 4, 7, or 14 days and examined the cytotoxic activity of splenocytes was measured. RNA was extracted from the spleen and analyzed for gene expression by DNA microarray.

Aquaporin-11 (AQP11), a new member of the aquaporin family, is localized in the endoplasmic reticulum (ER). Aqp11/ mice neonatally suffer from polycystic kidneys derived from the proximal tubule. Its onset is proceeded by the vacuolization of ER. However, the mechanism for the formation of vacuoles and the development of cysts remain to be clarified. Here, we show that Aqp11/ mice and polycystic kidney disease animals share a common pathogenic mechanism of cyst formation.

Description
Dietary collagen hydrolysate has been conjectured to improve skin barrier function. To investigate the effect of long-term collagen hydrolysate administration on the skin, we evaluated stratum corneum water content and skin elasticity in intrinsic aged mice. Female 9-week-old hairless mice were fed a control diet, or a collagen hydrolysate-containing diet, for 12 weeks. The stratum corneum water content and skin elasticity were sequentially decreased by chronological aging in control mice. Intake of collagen hydrolysate significantly suppressed such changes. Moreover, we comprehensively analyzed gene expression in the skin of mouse, which had been administered collagen hydrolysate, using DNA microarray. Twelve weeks after start of collagen intake, no significant differences appeared in gene expression profile compared to that of control group. However, 1 week after administration, 135 genes were up-regulated and 448 genes were down-regulated in collagen group compared to control group. It is indicate that gene changes preceded changes of barrier function and elasticity. We focused on several genes correlated with functional changes in the skin. Gene Ontology terms, especially related to epidermal cell development, were signicantly enriched in up-regulated genes. These skin function-related genes had properties that facilitate epidermal production and differentiation and suppress dermal degradation. Thus, dietary collagen hydrolysate induced positive gene changes. In conclusion, our results suggest that alteration of gene expression at early stages after collagen administration affect skin barrier function and mechanical properties. Long-term oral intake of collagen hydrolysate improves skin dysfunction by regulating genes related to production and maintenance of the skin tissue.

Description
Ingestion of collagen peptide elicits beneficial effects on the body. Improvement of blood lipid is one of the effects, but its mechanism remains unclear. Male BALB/cCrSlc mice were bred with the AIN-93M diet containing 14% casein or AIN-93M-based low-protein diet containing 10% casein or diet containing 6% casein+4% collagen peptide (n=12/group) for 10 weeksTotal, free, and esterified cholesterol levels in the blood decreased in the collagen peptide group. DNA microarray analysis of the liver revealed that expression of the genes related to lipid metabolic process, such as PPAR signaling pathway and fatty acid metabolism, increased in the collagen peptide group compared to the 10% casein group. In contrast, expression of the genes related to unfolded protein response (UPR) and protein level of phospho-IRE1 decreased. Our data suggest that lipid metabolism in the liver was altered by collagen ingestion, which probably results in the decreased levels of blood cholesterol.
