RNF43 and colorectal carcinoma: Additionally, the RING finger gene FLJ20315/RNF124, possibly encoding a novel E3 ubiquitin ligase, and the suppressor of Ty 4 homologue 1 (SUPT4H1), a putative human chromatin regulator that alters transcription, are genes that are strongly up-regulated and could have the potential to contribute to development of CRC.
