Statistical analysis comparing ABCF1 reduction and siRNA control treated HBEC-6KT confirmed ABCF1 gene was down-regulated (Figure 2F) which was associated with only one other significantly differentially expressed (up or down) gene, C12orf75, which encodes overexpressed in colon carcinoma-1 (OCC-1) protein. This evidence concerns the gene C12orf75 and colon carcinoma.
