MAGI1 mediates tumor metastasis through c-Myb/miR-520h/MAGI1 signaling pathway in renal cell carcinoma

In this study, we demonstrated that MAGI1 was markedly decreased in the RCC and indicated poor survival. Furthermore, we found that MAGI1 suppressed the invasion and migration of human RCC cells. Mechanistic investigations revealed that MAGI1 stabilized the PTEN/MAGI1/ β-catenin complex to inhibit β-catenin signaling pathway. Moreover, MAGI1 was targeted by miR-520h which was transcriptionally activated by c-Myb. Collectively, our findings suggested that MAGI1mediated tumor metastasis through c-Myb/miR-520h/MAGI1 signaling pathway in RCC.

Conclusion Review of literature and our case strengthens the idea of meningioma as a favorable premetastatic niche. Considering that the patient lived with a stable disease for many years, a sudden progress of tumor size in association with neurological deterioration was highly suspected for malign involvement, including the possibility of tumor-to-tumor metastasis. Physicians should be aware about this phenomenon and treat patients accordingly to the underlying disease.

Chiu Lin : Clear cell renal cell carcinoma (ccRCC) is the main type of RCC, which is the most common type of malignant kidney tumor in adults. A subpopulation (>30%) of ccRCC patients develop metastasis; however, the molecular mechanism remains largely unknown. Here, we found that LTF, the gene encoding lactotransferrin, is dramatically downregulated in primary tumors compared to normal tissues derived from ccRCC patients deposited in The Cancer Genome Atlas (TCGA) database and is a favorable prognostic marker. Moreover, LTF downregulation appears to be more dominant in metastatic ccRCC. LTF overexpression s...

This study aims to evaluate the oncological and functional results of open partial nephrectomy (OPN) and laparoscopic partial nephrectomy (LPN) at the T1b clinical stage, which constitutes 25% of renal cell carcinomas (RCC) at diagnosis. Materials and Methods: The characteristics of 63 patients with stage T1b solitary tumor who underwent OPN (41) or LPN (22) were compared. The survival analysis was performed using the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were performed to determine the factors affecting disease-free survival. Potential predictive factors, which might affect the postopera...

This study was approved by the review board (NO.XYFY2019-KL032-01). Between 2007 and 2016, a total of 384 consecutive patients who underwent curative surgery for sRCC at our institution were evaluated. Patients were divided into high NLR and low NLR groups by plotting the NLR receiver operating characteristic curve. The Kaplan-Meier method was utilized to graphically display survivor functions. Univariate and multivariate Cox proportional hazards regression analysis addressed time to overall survival (OS) and cancer-specific survival (CSS). Results: Of the 384 patients, 264 (68.8%) were males and 120 (31.2%) were fema...

ConclusionsIntegration of HLA ligandomics, transcriptomics, genetic, and epigenetic data leads to the identification of novel functionally relevant therapeutic targets for ccRCC immunotherapy. Validation of the identified targets is recommended to expand the treatment landscape of ccRCC.

ConclusionsWe find sufficient cause to suggest that the predictive clinical value of TMB should not be overstated or oversimplified. While it is readily quantified, TMB is at best a limited surrogate biomarker of immunotherapy response. The data do not support isolated use of TMB in renal cell carcinoma.

Authors: Li R, Wang L, Wang X, Geng RX, Li N, Liu XH Abstract Clear cell renal cell carcinoma (ccRCC) is one of the most common tumor types of the urinary system. Bioinformatics tools have been used to identify new biomarkers of ccRCC and to explore the mechanisms underlying development and progression of ccRCC. The present study analyzed the differentially expressed genes (DEGs) associated with RCC using data obtained from Gene Expression Omnibus datasets and GEO2R software. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of these DEGs was performed and analyzed us...

Conclusions: The results of the present retrospective study demonstrate the suitability of the MSKCC model in mRCC patients treated with first-line sunitinib and suggest different outcomes between patients with one or two risk factors.
