For breast cancers, the statistical correlation analysis for HITS expression and the clinicopathological parameters of human epidermal growth factor 2 (HER2), estrogen receptor, progesterone receptor (PR), Ki-67 and p53 revealed that HITS expression intensity was positively correlated with the expression of HER2 and Ki-67, but was inversely correlated with PR expression. Here, PGR is linked to breast cancer.
