In conclusion, the results of the current study present evidence emphasizing the significance of the interactions between miR-539 and TWIST1 in the development of and progression of PC, highlighting its potential as a therapeutic target in the treatment of PC patients.
In addition, we confirmed that the overexpression of HIF-2α increased Twist1 expression and promoted tumor growth and VM formation in pancreatic cancer xenografts in nude mice.
ASX was identified to upregulate human equilibrative nucleoside transporter 1 (hENT1) and downregulate ribonucleoside diphosphate reductase (RRM) 1 and 2 to enhance gemcitabine-induced cell death in GR-HPCCs treated with gemcitabine, and also downregulates TWIST1 and ZEB1 to inhibit the gemcitabine-induced epithelial-mesenchymal transition (EMT) phenotype in GR-HPCCs and to mediate hENT1, RRM1 and RRM2.
In addition, our results showed that miR-1271 expression levels were decreased while ZEB1 and TWIST1 expression levels were increased in detected PC cell lines.
These data indicate that MSX2 plays a crucial role in pancreatic cancer development by inducing changes consistent with epithelial to mesenchymal transition through enhanced expression of Twist 1.
