Hao et al. detected the CIAPIN1 distribution in a series of cultured cell lines, such as mouse fibroblast cell line NIH3T3, human tumor cell lines, and immortalized cell lines by the use of molecular techniques of immunofluorescence staining, immunohistochemistry, and EGFP-CIAPIN1 fusion protein [12]. This evidence concerns the gene CIAPIN1 and neoplasm.
