Figure 1. The expression of HCG11 was decreased in HR-positive BC cells. (A, B) Expression of HCG11 in BC tissues according to the data from UALCAN database. (C) Relative expression of HCG11 in HR-positive BC tissues. (D) Relative expression of HCG11 in HR-positive BC cell lines. (E, F) Expression levels of cytoplasmic control transcripts (GAPDH), the nuclear control transcript (U6), and HCG11 were determined by qRT-PCR in the cytoplasmic and nuclear fractions of MCF-7 and BT-474. *p<0.05, **p<0.01, ***p<0.001, **** p<0.0001.
