MicroRNA-154 functions as a tumor suppressor and directly targets HMGA2 in human non-small cell lung cancer

H. C. Zhuo, Song, Y. F., Ye, J., Lai, G. X., and Liu, D. L., MicroRNA-154 functions as a tumor suppressor and directly targets HMGA2 in human non-small cell lung cancer, vol. 15, p. -, 2016.

MicroRNA-154 (miR-154) is dysregulated in some human malignancies and is correlated with tumor progression. However, its expression and function in non-small cell lung cancer (NSCLC) remain unclear. Therefore, we explored the effects of miR-154 on NSCLC tumorigenesis and development. Using quantitative reverse transcription-polymerase chain reaction, we detected miR-154 expression in NSCLC cell lines and primary tumor tissues.

NDC80 promotes proliferation and metastasis of colon cancer cells

X. K. Xing, Wu, H. Y., Chen, H. L., Feng, H. G., Xing, X. K., Wu, H. Y., Chen, H. L., and Feng, H. G., NDC80 promotes proliferation and metastasis of colon cancer cells, vol. 15, p. -, 2016.

Chromosome instability is a common feature of tumor cells, and may be an important mechanism in tumor formation. Nuclear division cycle 80 (NDC80) is closely associated with the stability of chromosomes. Therefore, we investigated the relationship between NDC80 and development of colon cancer using a range of methods.

Inhibition of subcutaneously implanted human pituitary tumor cells in nude mice by LRIG1

X. Wang, He, X. J., Xu, H. Q., Chen, Z. W., Fan, H. H., Wang, X., He, X. J., Xu, H. Q., Chen, Z. W., and Fan, H. H., Inhibition of subcutaneously implanted human pituitary tumor cells in nude mice by LRIG1, vol. 15, p. -, 2016.

The aim of this study was to explore the inhibition of subcutaneously implanted human pituitary tumor cells in nude mice by LRIG1 and its mechanism. For this study, athymic nude mice were injected with either normal pituitary tumor RC-4B/C cells or LRIG1-transfected RC-4B/C cells. We then calculated the volume inhibition rate of the tumors, as well as the apoptosis index of tumor cells and the expression of Ras, Raf, AKt, and ERK mRNA in tumor cells. Tumor cell morphological and structural changes were also observed under electron microscope.

MicroRNA-32 functions as a tumor suppressor and directly targets EZH2 in uveal melanoma

Y. B. Ma, Song, D. W., Nie, R. H., and Mu, G. Y., MicroRNA-32 functions as a tumor suppressor and directly targets EZH2 in uveal melanoma, vol. 15, p. -, 2016.

MicroRNA-32 (miR-32) has been shown to be dysregulated in some human malignancies and this has been found to be correlated with tumor progression. However, its role in uveal melanoma formation and progression remains largely unknown. Thus, the aim of this study was to explore the expression and function of miR-32 in human uveal melanoma. Using quantitative reverse transcription-polymerase chain reaction, we detected miR-32 expression in uveal melanoma tumor tissues and cell lines. The effects of miR-32 on the biological behavior of uveal melanoma cells were also investigated.

Tristetraprolin: a novel mediator of the anticancer properties of resveratrol

C. Li, Tang, C., He, G., Li, C., Tang, C., and He, G., Tristetraprolin: a novel mediator of the anticancer properties of resveratrol, vol. 15, p. -, 2016.

Resveratrol is a natural compound that exhibits anticancer properties. Previous studies have proved that it can inhibit the proliferation of breast cancer cell lines and upregulate some cytokines such as cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF). The initiation and progression of cancer are associated with the abnormal expression of multiple cytokines. Tristetraprolin (TTP), an mRNA-binding protein, is one of the key proteins that participate in regulating cytokine expression.

Receptor for advanced glycation end-products (RAGE) is overexpressed in human osteosarcoma and promotes the proliferation of osteosarcoma U-2OS cells in vitro

Q. Zhang, Jin, Y., Zhao, C. F., Wang, W. J., Liu, G. Y., Zhang, Q., Jin, Y., Zhao, C. F., Wang, W. J., and Liu, G. Y., Receptor for advanced glycation end-products (RAGE) is overexpressed in human osteosarcoma and promotes the proliferation of osteosarcoma U-2OS cells in vitro, vol. 15, p. -, 2016.

Osteosarcoma (OS) is an aggressive cancer of the long bones, and usually affects children and young adults. The receptor for advanced glycation end-products (RAGE) has recently been recognized as an oncogenic receptor that binds to different ligands, and promotes the progression of various cancers. However, little is known about the association between RAGE and the pathogenesis of OS. In this study, we first examined the expression of RAGE in OS tissues using immunohistochemical staining, western blotting, and reverse transcription quantitative polymerase chain reaction.

Propofol inhibits proliferation and accelerates apoptosis of human gastric cancer cells by regulation of microRNA-451 and MMP-2 expression

Z. Peng, Zhang, Y., Peng, Z., Zhang, Y., Peng, Z., and Zhang, Y., Propofol inhibits proliferation and accelerates apoptosis of human gastric cancer cells by regulation of microRNA-451 and MMP-2 expression, vol. 15, p. -, 2016.

Propofol is an extensively used intravenous anesthetic agent. The aim of the present study was to evaluate the effects of propofol on the behavior of human gastric cancer cells and the molecular mechanisms associated with this activity. The effects of propofol on proliferation and apoptosis in the SGC-7901 gastric cancer cell line were detected by an MTT assay and measurement of caspase-3 activity. The protein expression levels of matrix metalloproteinase-2 (MMP-2) were detected by western blotting.
