Over-expression of mir-124 inhibits MMP-9 expression and decreases invasion of renal cell carcinoma cells.

CONCLUSIONS: MiR-124 down-regulation was associated with renal cancer cell OS-RC-2 invasion enhancement. Over-expression of miR-124 attenuated OS-RC-2 cell invasion by down-regulating STAT3 and MMP-9. PMID: 30338828 [PubMed - in process]

This study provides definitive evidence and possible mechanisms of intra-familial phenotypic heterogeneity in VHL families, which is helpful to the update of surveillance guidelines. Introduction von Hippel-Lindau (VHL) disease (MIM 193300) is a rare autosomal dominant cancer syndrome caused by germline mutations in the VHL tumor suppressor gene (Latif et al., 1993; Lonser et al., 2003). Generally, the first VHL-related manifestation occurred in the third decade of patient’s life, and the penetrance is more than 90% by 70 years old (Ong et al., 2007; Nordstrom-O’brien et al., 2010). Patients may develop...

AbstractIntroductionBased on the observation of beneficial effects on cancer metabolism, microenvironment, or VEGF-signaling, several non-anticancer drugs have been discussed as useful in renal cell carcinoma (RCC). In the present study, we investigated the prognostic impact of concomitant medication in RCC and correlated comedication with cell-cycle and proliferation activity in corresponding surgical specimen.MethodsA total of 388 patients who underwent surgery for localized RCC were included. The individual medication was evaluated according to substance classes. Tissue microarrays from corresponding tumor specimen were...

This study aimed to investigate whether CD18 affects renal carcinoma cell proliferation. MATERIALS AND METHODS: Thirty mice with renal cell carcinoma were constructed using gene-engineering mouse with CD18 deficiency, and another 30 normal C57 mice were used as control. Ki67 and micro-vessel density were detected by using immunohistochemistry (IHC) and immunofluorescence, respectively. The expression of CD3, CD4 and CD8 were detected in blood and spleen by quantitative PCR (q-PCR). Flow cytometry was used to detect the changes of Treg cells. RESULTS: The expression of Ki67 in C57 was significantly higher than that in CD18-/- mice (p

Authors: Maleckaite R, Zalimas A, Bakavicius A, Jankevicius F, Jarmalaite S, Daniunaite K Abstract Metallothioneins are low‑weight cysteine‑rich proteins responsible for metal ion homeostasis in a cell and, thus, capable of regulating cell proliferation and differentiation. Deregulation of metallothionein genes has been reported in various human tumors. However, their role in renal cell carcinoma (RCC) has been poorly investigated. In the present study, we aimed to evaluate the importance of promoter DNA methylation of selected metallothionein genes for RCC. Based on the initial analysis of kidney renal clear c...

Authors: Wei W, Lv Y, Gan Z, Zhang Y, Han X, Xu Z Abstract Clear cell renal cell carcinoma (ccRCC) is the most common and lethal renal malignant tumor in adults. The aim of the present study was to identify the key genes involved in ccRCC metastasis. Expression profiling data for ccRCC patients with metastasis and without metastasis were obtained from The Cancer Genome Atlas database. The datasets were used to identify differentially expressed genes (DEGs) between the metastasis group and the non-metastasis group using the DESeq2 package. Function enrichment analyses of DEGs were performed. The protein-protein inte...

CONCLUSIONS: sE-cadherin is overexpressed in serum of RCC patients and provides a functional cellular switch from sessility to aggressive dissemination. While sE-cadherin is not tumor-specific and thus inappropriate for population-based screening, further studies are warranted to investigate its role in monitoring RCC and employing it as a therapeutic target.

In this study, we evaluated whether the combination of focused ultrasound (FUS) and microbubbles can improve adoptively NK-92MI cell infiltration into ovarian tumors through biodistribution, immunofluorescence, and flow cytometry. The treatment effects of using this strategy twice a week were explored. The potential molecular mechanism of FUS assisting NK cell therapy was also initially explored through evaluating the expression of ICAM1 and CX3CL1 by qRT-PCR. Our results indicated that FUS and microbubbles can improve NK-92MI cells’ infiltration into tumors, and the combination of FUS and NK-92MI cells had a better ...
