XIST and neoplasm: Interestingly, the highly metastatic Lovo cell line showed the topmost XIST expression and the minimum miR‐30a‐5p expression (P < 0.05), yet the non‐metastatic and tumour‐generating SW480 cell line was correlated with the highest miR‐30a‐5p expression and yet the lowest XIST expression among the CRC cell lines studied (P < 0.05).
