Stimulation of HEK293, HeLaS3 or KKLS gastric cancer cells with WNT5A promotes the internalization of FZD2, FZD5 and ROR2. Internalization is required for RAC activation downstream of WNT5A and subsequent activation of laminin gamma 2 gene expression which is associated with metastasis and invasion in gastric cancer (Sato et al, 2010; Hanaki et al, 2012; Yamamoto et al, 2009). Knockdown or inhibition of clathrin abrogates receptor internalization and RAC activation suggesting that clathrin-mediated endocytosis is required for this WNT5A-dependent signaling (Sato et al, 2010; Hanaki et al, 2012).
