Abstract Breast cancer is one of malignant severe diseases that cause cancer death in women. Although research about the pathogenesis and studies about treatment mechanisms in breast cancer have become clear focuses, we have no clear conclusion yet. Therefore, this research is based on a modular approach to explore key factors and molecular mechanisms that affect breast cancer metastasis. First of all, it is necessary to download breast cancer-related data on the GEO database, and we analyzed the difference between primary tumors and metastatic lesions to obtain differential gene expression profiles. On this basis, a series… More >

Abstract Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. MicroRNA (miRNA), a class of noncoding single-stranded RNA molecules, is involved in regulating cancer cell proliferation, metastasis, migration, invasion, and apoptosis. We showed that the expression of miR-346 was significantly increased in HCC tissues and cell lines, compared with noncancerous controls, and was associated with poor prognosis. Overexpression of miR-346 promoted proliferation and inhibited apoptosis of SMMC-7721 cells, while knockdown of miR-346 significantly suppressed proliferation and induced apoptosis of HepG2 cells. Then we identified breast cancer metastasis suppressor 1 (BRMS1) as a direct More >
