BATF2 and gastric cancer: Both multidrug resistance (MDR)-related proteins and Wnt/β-catenin pathway markers were upregulated in gastric cancer drug-resistant cells, overexpression of the novel tumor suppressor basic leucine zipper ATF-like transcription factor 2 (BATF2) inhibited the Wnt/β-catenin pathway to improve drug sensitivity and attenuate gastric cancer drug resistance (73).
