MORC2 and cancer: The results indicated that the overexpressed MORC2 group developed markedly heavier tumor weight (supplementary Figure 3a), larger volume (supplementary Figure 3b) and accelerated PCNA staining (supplementary Figure 3c, right panel) than vector control group, which is consistent with the result of SGC-7901 cell lines [20], indicating that the increased MORC2 expression and low level of C/EBPα contribute to proliferation and tumorigenesis of cancer cells.
