HOXA9 and colorectal carcinoma: The restoration of HOXA9 expression in cells expressing miR-133b mimic blocked the miR-133b-induced suppression of migration and invasion (Figure 6A) and knockdown of HOXA9 abolished migration and invasion elevation in miR-133b inhibited cells (Figure 6B), indicating that HOXA9 mediated the suppressive effects of miR-133b on CRC migration and invasion.
