CCR7 and pancreatic ductal adenocarcinoma: Twist expression significantly correlated with CCR7 and CXCR4 levels, leading the authors to speculate that Twist might regulate CXCR4 and CCR7 expression, although it seems more likely to be the other way round since, at least for pancreatic ductal adenocarcinoma, it was shown that CCR7 regulates Twist [148].
