ARAF and colorectal carcinoma: Recent studies on colon organoids have shown that short-term infection with pks+ E. coli promoted the generation of organoids that, due to endogenous Wnt production, which is normally required for cell determination and proliferation [77], grew independently of Wnt supplementation in the culture medium [78], thus resembling aberrant Wnt signalling, which is observed in the majority of colorectal carcinoma (CRC) patients [79,80].
