Since GATA3-AS1 expression correlates with GATA3 expression in breast tumors [27], we analyzed GATA3-AS1 and GATA3 expression levels by RT–qPCR of cDNA from paraffin-embedded tissue from 49 pre-NAC Hispanic LABC luminal subtype B tumors using two different housekeeping genes (RPLP0, Figure 8A,B. The gene discussed is GATA3; the disease is breast neoplasm.
