HOXA3 and colorectal carcinoma: For example, we found two CpG islands of the HOXA3 gene as the top 1 (chr7:27,147,589-27,148,389; hereafter HOXA3_CGI 7) and 2 (chr7:27,146,069-27,146,600; hereafter HOXA3_CGI 6) candidates that satisfied our criteria, but we failed to determine whether the expression of HOXA3 was significantly changed in CRC patients (Table 1, Supplementary Figs. 5 and 10).
