Dickkopf AND Dihydromyricetin

Ellagic acid (EGA) and dihydromyricetin (DHM) are both found in fruits and vegetables are used for anti-aging treatment for the skin. The anti-photoaging efficacy of EGA and DHM was investigated in UV-B irradiated skin in vivo and the involvement of transforming growth factor (TGF)-β1 and wnt signaling pathways were examined in vitro. HaCaT cells were treated with either 50μM EGA, 50μM DHM or 25μM EGA+25μM DHM before 100mJ/cm2 UV-B exposure, and then oxidative stress and inflammation was measured...

Substantial evidence has demonstrated that the decreased osteogenic differentiation of bone mesenchymal stem cells (BMSCs) is closely related to bone metabolic diseases. Thus, it is very important to develop several potentially useful therapeutic agents to enhance BMSC osteogenesis. Flavonoids show promise in enhancing bone mass. Dihydromyricetin (DMY), a type of flavonoid, has not yet been investigated regarding its effects on BMSC osteogenesis. To investigate the effects of DMY on osteogenesis, human BMSCs were induced with or without DMY...
