TY - JOUR ID - 28776 TI - Differential Wnt11 Expression Related to Wnt5a in High- and Low-grade Serous Ovarian Cancer: Implications for Migration, Adhesion and Survival JO - Asian Pacific Journal of Cancer Prevention JA - APJCP LA - en SN - 1513-7368 Y1 - 2014 PY - 2014 VL - 15 IS - 3 SP - 1489 EP - 1495 KW - Epithelial Ovarian Cancer KW - Wnt11 KW - Wnt5a KW - Adhesion KW - migration KW - viability DO - N2 - Wnt is a powerful signaling pathway that plays a crucial role in cell fate determination, survival, proliferationand motility during development, in adult tissues and cancer. The aims of the present study were three fold: i) toassess Wnt11 immunoexpression and its possible relationship with Wnt5a in high- and low-grade human serousovarian cancer (HGSC and LGSC) specimens; ii) to assess Wnt11 expression levels in Wnt5a overexpressingSKOV-3 cells; iii) to reveal the role of Wnt11 in viability, adhesion, migration and invasion of SKOV-3 cellsusing recombinant human Wnt11 (rhWnt11). Immunohistochemistry revealed a significant difference in Wnt11expression between HGSC and LGSC groups (p=0.001). Moreover, a positive correlation was observed betweenWnt5a and Wnt11 expression in the HGSC (r=0.713, p=0.001), but not the LGSC group. The expression of Wnt11was decreased by 35% in Wnt5a overexpressing cells (SKOV-3/Wnt5a) compared to mock controls. SimilarlyWnt11 expression levels were decreased by 47% in the presence of exogenous Wnt5a compared to untreated cells.In the presence of rhWnt11, 31% increased cell viability (p<0.001) and 21% increased cell adhesion to matrigel(p<0.01) were observed compared to control. Cell migration was increased by 1.6-fold with rhWnt11 as revealedby transwell migration assay (p<0.001). However, 45% decreased cell invasion was observed in the presenceof rhWnt11 compared to control (p<0.01). Our results may suggest that differential Wnt11 immunoexpressionin HGSC compared to LGSC could play important roles in serous ovarian cancer progression and may bemodulated by Wnt5a expression levels.
