5-FU-based chemotherapy is recently most recommended as the first-line treatment for gastric cancer (GC). However, 5-FU resistance is common for many postoperative GC patients.
Homeobox A13
(
HOXA13
) is a member of homeobox genes highly expressed in many human tumors. Its potential roles and mechanisms of resistance to 5-FU in GC are poorly understood. In this study, we discovered that
HOXA13
played an oncogenic role in vivo and in vitro. The patients with
HOXA13
overexpression were closely related with poor prognosis and more prone to be resistant to 5-FU. Moreover, dehydrogenase/reductase 2 (DHRS2) was identified as a downstream gene of
HOXA13
.
HOXA13
played a role of carcinogenesis through directly down-regulating DHRS2 to increase MDM2. Furthermore,
HOXA13
conferred 5-FU resistance through MRP1 by a p53-dependent pathway. Therefore,
HOXA13
might serve as a potential signature that recognized patients who were insensitive to 5-FU, and timely recommended them to other chemotherapy regimens.
