Abstract. Increasing evidence indicates that dysregulation of miR-195 may contribute to the occurrence and development of multiple types of human malignancies. However, the function and the mechanism of miR-195 in clear cell renal cell carcinoma (ccRCC) are still not fully understood. In the present study, we used qRT-PCR to detect the expression of miR-195 in ccRCC tissues and normal kidney tissues. MTT assay was performed to detect the cell viability of miR-195. Migration and invasion were evaluated by Transwell migration and Matrigel invasion assays, respectively. Additionally, apoptosis levels were evaluated using TUNEL assays, and signaling pathway changes were determined by western blot analysis. We observed that miR-195 was downregulated in clear cell renal cell carcinoma samples compared with normal renal samples. We identified that overexpression of miR-195 inhibited ACHN cell viability, migration, invasion, and it also induced cell apoptosis by targeting VEGFR2 via PI3K/Akt and Raf/MEK/ERK signaling pathways. These findings indicate that miR-195 has a tumor suppressive role in ACHN cells and miR-195 may be a promising candidate target for prevention and treatment of renal cell carcinoma.

Typical industrial remote monitoring and control systems are usually based on PC, but it can hardly be applied to fields that need mobile communication. Along with the developing of wireless communication technology and mobile device, using mobile devices to realize wireless remote monitoring and control becomes possible and has vast development space. But the generally wireless remote monitoring and control can hardly realize a real time and continues control. In this paper we design a wireless monitoring and control system base on Android tablet PC for OGSTSS (oil and gas storage and transportation simulation system) to realize a real time and continues control.
