In efforts to validate the genes and identify a reliable subset of candidate genes, the list of 21 genes were examined experimentally via PCR using MCF7 (luminal), MCF10A (triple negative, non-tumor), MDA MB468 (TNBC, basal A), (HCC70 (TNBC, lower IL32) and MDA MB231 (TNBC, higher IL32) cell lines. Here, IL32 is linked to neoplasm.
