HSP90AA1 and gastric cancer: Moreover, Liu et al. found that an increased Hsp90 expression in gastric cancer cells correlated with elevated EMT-related markers—specifically N-cadherin, E-cadherin, vimentin, and Snail—and a greater proportion of CD90+ proliferative and CD44+ metastatic stem cells when compared to cells with blocked Hsp90 expression [112].
