... very dry skin applied the moisturizer or vehicle twice daily to their volar forearms for 2 weeks. Then, suction blister samples were obtained for gene expression analysis using RT-PCR. Results: Application of the actives led to significantly improved skin hydration and barrier function at all points...

.... Here, we investigated the effects of oral CP administration on gene expression in hairless mouse skin and of prolyl-hydroxyproline (Pro-Hyp), a collagen-derived dipeptide, on gene expression in a coculture of mouse skin keratinocytes and fibroblasts. Using microarray analysis, we found that oral...

... and digital imaging during a 9-month double-blind placebo-controlled study involving 48 volunteers. Finally, epidermal cell proliferation was evaluated using tryptophan fluorescence spectroscopy. Our results demonstrate that 0.1% ROL induced CRABP2 and HBEGF gene expression and increased keratinocyte...

...Raik Böckelmann; Bernd Bonnekoh; Harald Gollnick The differential display of cDNA species defined by a combination of so-called anchored and arbitrary primers has been acknowledged as a powerful complex strategy to identify differences in gene expression, and depends in its original version...
