Chang et al. (2021) found in a study of triple-negative breast cancer (TNBC) cohort that a high expression of IGLC2 was related to a favorable prognosis for TNBC patients, which is consistent with our results. In addition, IGLC2 is linked with the proliferation, migration, and invasion of MDA-MB-231 cells. Pathway enrichment analysis showed that IGLC2 is related to the extracellular matrix–receptor interaction (Chang et al., 2021). This evidence concerns the gene IGLC2 and triple-negative breast carcinoma.
