WNT5A and breast cancer: However, it should be noted that WNT5A mRNA levels have been documented not to correlate to the WNT5A protein levels in breast cancer tissue, since the translation of WNT5A mRNA can be regulated via its untranslated 3′-region, thereby generating discrepancies between WNT5A mRNA levels and protein expression [3, 17, 19, 20].
