In the IHC analysis using a tissue microarray of ovarian cancer including 80 tumor samples and 10 adjacent normal tissues, nearly three-quarters (n = 59, 73.8%) of tumor samples had a medium to high IHC scores of ACTL6A, whereas little positive staining was detected in the adjacent non-tumor tissues (Fig. 1f, g). This evidence concerns the gene ACTL6A and neoplasm.
