Abstract Although astragaloside IV exhibits anti-inflammation, immunoregulatory, and anticancer properties, the chemosensitization effects of astragaloside IV in colorectal cancer have never been reported. Our study tested whether astragaloside could increase cisplatin sensitivity in colorectal cancer. CCK-8 assay was used to measure the cell viability of colorectal cancer cells. Quantitative real-time PCR and Western blot were performed to determine the mRNA and protein expression, respectively. Our data revealed that astragaloside IV administration significantly suppressed the cell growth of colorectal cancer cells, whereas no obvious cytotoxicity of astragaloside IV was observed in nonmalignant colonic cells. In addition, combined… More >

Abstract Sparc/osteonectin, cwcv, and kazal-like domains proteoglycan (testican) 1 (SPOCK1), known as testican-1, were found to be involved in the development and progression of tumors. However, in colorectal cancer (CRC), the expression pattern of SPOCK1 and its functional role remain poorly investigated. In the present study, we explored the role of SPOCK1 in CRC. Our results demonstrated that SPOCK1 is overexpressed in CRC cell lines. SPOCK1 silencing significantly inhibited the proliferation in vitro and the tumor growth in vivo. Furthermore, SPOCK1 silencing significantly attenuated the migration/invasion by reversing the EMT process in CRC cells. Finally, knockdown More >

Abstract Hepatocyte cell adhesion molecule (hepaCAM), a new type of CAM, belongs to the immunoglobulin superfamily. Recently, hepaCAM was reported to be implicated in cancer development, and many researchers investigated its biological function in the tumorigenesis of various cancers. However, what kind of role hepaCAM plays in colorectal cancer (CRC) remains unknown. In this study, we found that hepaCAM was downregulated in CRC tissues and cell lines. Overexpression of hepaCAM inhibited CRC cell proliferation, migration, and invasion in vitro. Furthermore, the tumorigenesis assay showed that increased expression of hepaCAM suppressed CRC tumor growth and metastasis in More >

Abstract Colorectal cancer (CRC) is one of the most common malignancies in the world, with a high incidence and a high mortality. However, the pathogenesis of CRC carcinogenesis is still unexplored. In this study, we investigated the role of miR-107 in the regulation of CRC cell proliferation and apoptosis. First, the expression of miR-107 was observed to be aberrantly increased in human CRC tumor tissues and cell lines when compared to the colonic control tissues and colon epithelial cells. Further study showed that the proliferative and apoptotic capacities of human CRC SW480 and LoVo cells were… More >

Abstract Forkhead box R2 (FOXR2), a member of the FOX gene family, has not been very well investigated for its role in cancer. A recent study has shown that FOXR2 is highly expressed in breast cancer samples and is associated with poor prognosis. In addition, FOXR2 was identified as an oncogene in medulloblastoma. Nevertheless, whether FOXR2 plays a role in colorectal cancer (CRC) remains unclear. In the present study, we conducted several in vitro and in vivo studies to investigate the expression and effect of FOXR2 in CRC. The study results demonstrated that FOXR2 was upregulated More >

Abstract Cancer cell-derived exosomes have been actively released into the tumor microenvironment with pleiotropic roles in tumor growth and metastasis, including angiogenesis and immune modulation. However, the functions and underlying mechanisms of exosomes shed by colorectal cancer (CRC) cells under hypoxic conditions remain unknown. Here we found that exosomes derived from hypoxic CRC cells promoted the proliferation and migration of endothelial cells. Suppression of exosome secretion through RAB27a knockdown in CRC cells inhibited exosomal-induced proliferation and migration of endothelial cells. Furthermore, we discovered that these exosomes enriched with Wnt4 were dependent on HIF1α. Exosomal Wnt4 increased More >

Abstract Empty spiracles homeobox 2 (EMX2) is a homeodomain-containing transcription factor that plays an essential role in tumorigenesis. However, to the best of our knowledge, the role of EMX2 in human colorectal cancer (CRC) is still unclear. Thus, the aim of this study was to investigate the expression and role of EMX2 in CRC. Our results demonstrated that the expression of EMX2 was greatly decreased in CRC tissues and cell lines. Overexpression of EMX2 significantly inhibited the proliferation in vitro and CRC tumor growth in nude mice. In addition, EMX2 also inhibited the migration and invasion More >

Abstract Tripartite motif-containing protein 37 (TRIM37), a new member of the RING-B-box-coiled-coil (RBCC) subfamily of zinc finger proteins, was found to be involved in the development and progression of several cancers. However, the expression pattern and biological functions of TRIM37 in colorectal cancer (CRC) remain unknown. Therefore, in the present study, we examined the expression pattern of TRIM37 in CRC and investigated the function of TRIM37 in the progression of CRC. Our results showed that TRIM37 expression was upregulated in CRC cell lines. Knockdown of TRIM37 inhibited CRC cell proliferation and tumor growth in vivo. Furthermore, More >

Abstract Previous study indicates that long noncoding RNA NORAD could serve as a competing endogenous RNA to pancreatic cancer metastasis. However, its role in colorectal cancer (CRC) needs to be investigated. In the present study, we found that the expression of NORAD was significantly upregulated in CRC tissues. Furthermore, the expression of NORAD was positively related with CRC metastasis and patients’ poor prognosis. Knockdown of NORAD markedly inhibited CRC cell proliferation, migration, and invasion but induced cell apoptosis in vitro. In vivo experiments also indicated an inhibitory effect of NORAD on tumor growth. Mechanistically, we found More >

Abstract Accumulated studies have strongly implicated aberrantly expressed microRNAs (miRNAs) in carcinogenesis and cancer progression of various cancers, including colorectal cancer (CRC). Hence, a comprehensive study of miRNAs and their association with CRC may be a promising therapeutic method for patients with this malignancy. MicroRNA-744 (miR-744) is abnormally expressed in several types of human cancer. Thus far, little is known about the expression, biological roles, and exact mechanisms of miR-744 in CRC. Thus, the present study measured the expression level of miR-744 and investigated its roles and associated molecular mechanisms in CRC. This study demonstrated that… More >
