In particular, COL3A1 and MYH11 aroused our attention, because, according to the Gene Ontology (GO) analysis in DAVID, it was shown that COL3A1 was involved in the biological process of skeletal system development and cell-matrix adhesion, and MYH11 was involved in the biological process of elastic fiber assembly, which were similar to the findings of previous studies that they could promote metastasis in breast cancer. The gene discussed is COL3A1; the disease is breast cancer.
