Serum Hsp90α level was positively correlated with ALT (r = 0.827, p = 0.000), liver mass (r = 0.800, p = 0.000), the area of hepatic steatosis (r = 0.695, p = 0.006), the score of steatosis grade in the NAS (r = 0.668, p = 0.013), and the NAS (r = 0.661, p = 0.010) (Figures 6G–M). Here, HSP90AA1 is linked to fatty liver disease.
