Adjacent normal breast tissue was used as control.p = ns (control vs. cases) for both molecules.High levels of IE were increased in BC compared to control (p < 0.001), and it was related with low levels of ERα expression in BC samples.High levels (>50% cells) of LA were increased in BC compared to DCIS (p = 0.01). The gene discussed is ESR1; the disease is ductal breast carcinoma in situ.
