WNT11
Protein Wnt-11 precursor
Publications[править]
WNT signaling pathways play important roles in the behavior of human bone marrow stromal cells. Although WNT expression has been examined in human bone marrow stromal cells (hMSCs) with limited numbers of subjects or from commercial sources, there are conflicting results on WNT gene expression in hMSCs. Furthermore, the effects of age and gender on WNT expression in hMSCs are largely unknown. In this study, we evaluated RNA expression of all the WNT genes in hMSCs from 19 subjects, 12 women and 7 men, aged from 36 to 85 years. Analysis of WNT gene expression in young and old groups indicated that WNT7B and 14 were expressed significantly higher in the young group. WNT2 and WNT13 showed a trend of higher expression in young group. WNT7B, 13, and 14 were inversely correlated with age. Further analysis for gender-specific difference indicated that WNT16 was expressed significantly higher in men than in women. WNT11 showed a trend of higher expression in hMSCs from women. For the hMSCs from women, WNT13 was inversely correlated with age and WNT4 was positively correlated with age. For the hMSCs from men, WNT7B and WNT14 were inversely correlated with age. These data indicated that most of the age-related WNT genes belong to the canonical WNT signaling pathway. Further, there are gender-specific differences in the expression of WNT4, 7B, 13, 14, and 16 in hMSCs. Age and gender account for many of the sample-to-sample variations in WNT gene expression in human marrow stromal cells.
