Expression of COL6A1-A3 and FN1 was high both in primary tumor and metastatic tissues, pre- and post-chemotherapy, while COL6A5-A6 and VTN expression was lower (Fig. 5b; primary tumor pre-chemo n = 32/post-chemo n = 13; metastatic tissues n = 55/n = 38; Supplementary Data 26). The gene discussed is VTN; the disease is neoplasm.
