We showed that KDM2A [20] and HP1γ (Figure 6 and Table 1) are expressed in breast cancer tissues, including TNBCs, and that KDM2A with HP1γ reduced rRNA transcription and cell proliferation on glucose starvation in a TNBC line MDA-MB-231 (Figure 7). This evidence concerns the gene KDM2A and breast carcinoma.
