Abstract The gene solute carrier family 34 (sodium phosphate), member 2 (SLC34A2), is a member of the SLC34 family. Increasing evidence suggests that SLC34A2 is involved in the development of many human carcinomas. However, its role in hepatocellular carcinoma (HCC) is still unclear. Therefore, in this study we investigated the role of SLC34A2 in HCC and explored the underlying mechanism. We found that the expression of SLC34A2 is upregulated in HCC cell lines. Knockdown of SLC34A2 obviously inhibited HCC cell proliferation, migration/invasion, and the epithelial–mesenchymal transition (EMT) phenotype. Furthermore, knockdown of SLC34A2 significantly inhibited the expression 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 Ovarian cancer is a malignancy with high mortality among women. Multiple reports show that microRNAs (miRs) act as regulators in ovarian cancer inhibition, while the role of miR-1284 in ovarian cancer is still unknown. This study aimed to investigate the effects of miR-1284 on ovarian cancer cells. Human ovarian cancer cell line OVCAR3 was cultured and transfected with miR-1284 mimics, inhibitors, or control. Viability and apoptosis of transfected cells were then determined by MTT assay, BrdU assay, and flow cytometry. Expression changes of p27, p21, and PI3K/Akt pathway-related proteins were measured by Western blot. Results More >

Abstract Tripartite motif 44 (TRIM44), a member of the TRIM protein family, has been shown to play a role in tumor development and progression. However, the potential involvement of TRIM44 in prostate cancer has not been fully explored. Therefore, in the present study, we analyzed the expression of TRIM44 in prostate cancer and assessed the role of TRIM44 in the progression of prostate cancer. Our results showed that the expression of TRIM44 was significantly upregulated in human prostate cancer cell lines. In addition, knockdown of TRIM44 significantly inhibited the proliferation, migration, and invasion of prostate cancer More >

Abstract Homeobox B7 (HOXB7), a member of the HOX gene family, plays a role in tumorigenesis. However, until now the expression status and role of HOXB7 in osteosarcoma remain unclear. Therefore, the present study aimed to investigate the functional role and mechanism of HOXB7 in osteosarcoma. Our results demonstrated that HOXB7 was overexpressed in osteosarcoma cell lines. Downregulation of HOXB7 significantly inhibited osteosarcoma cell proliferation in vitro, as well as attenuated xenograft tumor growth in vivo. Downregulation of HOXB7 also inhibited the migration and invasion of osteosarcoma cells. Furthermore, downregulation of HOXB7 significantly suppressed the protein More >

Abstract Ribosomal protein L34 (RPL34) belongs to the L34E family of ribosomal proteins and contains a zinc finger motif. Aberrant expression of RPL34 has been reported in several human malignancies. However, the precise role and potential underlying mechanisms of RPL34 in human esophageal cancer remain largely unknown. Thus, the objective of this study was to investigate the role of RPL34 in esophageal cancer progression. Our results showed that the expression of RPL34 at both the mRNA and protein levels was frequently upregulated in esophageal cancer cell lines. Knockdown of RPL34 efficiently inhibited esophageal cancer cell proliferation, More >

Abstract Pediatric glioma is a devastating brain tumor. Serine threonine tyrosine kinase 1 (STYK1) is a member of the protein tyrosine kinase family and plays a significant role in the formation of several malignant tumors. However, the expression pattern and role of STYK1 in glioma are not yet clear. The aim of this study was to investigate the role and molecular mechanism of STYK1 in glioma. The results showed that STYK1 was highly expressed in glioma cell lines. We also found that knockdown of STYK1 inhibited cell proliferation, migration, and invasion in vitro as well as More >

Abstract Latent transforming growth factor-b (TGF-b)-binding protein 2 (LTBP2) is one of four proteins in the LTBP family of proteins (LTBP1–4) and was shown to play a vital role in tumorigenesis. However, little is known regarding the functional role of LTBP2 in thyroid carcinoma. Therefore, the current study aimed to evaluate the effect of LTBP2 expression on the proliferation, invasion, and tumorigenesis in thyroid carcinoma cells and to explore the molecular mechanism of LTBP2 in tumor progression. Our results showed that the expression of LTBP2 is upregulated in human thyroid carcinoma and cell lines. Knockdown of More >

Abstract DDX46, a member of the DEAD-box (DDX) helicase family, is involved in the development of several tumors. However, the exact role of DDX46 in osteosarcoma and the underlying mechanisms in tumorigenesis remain poorly understood. Thus, in the present study, we explored the role of DDX46 in osteosarcoma and the underlying mechanisms. Our results demonstrated that the expression levels of DDX46 in both mRNA and protein were greatly elevated in human osteosarcoma tissues and cell lines. Knockdown of DDX46 obviously inhibited osteosarcoma cell proliferation and tumor growth in vivo. In addition, knockdown of DDX46 also significantly More >
