"To understand further the role of upstream Wnt-1 signaling regulation in human colorectal cancer, we first examined the Wnt-1 expression at the protein level using a monoclonal anti-Wnt-1 antibody that we recently developed (He et al., 2004) in colorectal cancer cell lines: SW480 and HCT116 (containing mutations in APC and CTNNB1, respectively) (Korinek et al., 1997; Morin et al., 1997). We found overexpression of the Wnt-1 protein in both cell lines examined (Figure 1a)."
So HCT116:

and SW480:

Seems good candidates and both are easily available and widely used.
Jonas, Amos thanks for the answers! We have these cells on hands. I'm going to test qPCR oligos for wnt1. So far in most cells the wnt1 level was barely detected.
