The expression of Col1 (COL1A1) and FN (FN1) were detected by western blotting (WB), quantitative real time-polymerase chain reaction (qRT-PCR), immunofluorescence (IF), and confocal laser scanning microscopy (CLSM) in cells and tumor tissue sections from mice xenografts, while the transcription of COL1A1 was detected by luciferase reporter gene assay. This evidence concerns the gene COL1A1 and neoplasm.
