Abstract Background: Clear cell renal cell carcinoma (ccRCC) is the most common form of adult kidney cancer. USP44 has been reported to be involved in various cancers. This study aimed to investigate the function role and molecular mechanism of USP44 in ccRCC. Methods: Data obtained from TCGA data portal and GSO database were analyzed to uncover the clinical relevance of USP44 expression and tumor development. The function of USP44 in cell proliferation and migration was assessed by cellular and molecular analysis. Results: USP44 was lowly expressed in the ccRCC cancer tissues compared to the normal tissue. Further, USP44 expression was negatively correlated with tumor stage, tumor grade, and patient survival . USP44 overexpression significantly inhibited tumor cell proliferation and migration of 786-O cell as well as Caki-1 cell. In addition, USP44 overexpression also prohibited cell proliferation by up-regulating P21, down-regulating Cyclin D1 expression, and inhibited cell migration by up-regulating MMP2 and MMP9 expression. In contrast, USP44 knockdown enhances ccRCC cell proliferation and migration. Furthermore, the USP44 function in inhibiting ccRCC cell proliferation and migration is associated with the phosphorylation level of JNK. Conclusion: In summary, this study showed that USP44 may be a marker in predicting the ccRCC progression and USP44 inhibits ccRCC cell proliferation and migration dependent on the JNK pathway.

Abstract Background: Despite the improvement of relapse-free survival mediated by anti-angiogenic drugs like sunitinib (Sutent ®), or by combinations of anti-angiogenic drugs with immunotherapy, metastatic clear cell Renal Cell Carcinoma (mccRCC) remain incurable. Hence, new relevant treatments are urgently needed. The VEGFs coreceptors, Neuropilins 1, 2 (NRP1, 2) are expressed on several tumor cells including ccRCC. We analysed the role of the VEGFs/NRPs signaling in ccRCC aggressiveness and evaluated the relevance to target this pathway.Methods: We correlated the NRP1, 2 levels to patients’ survival using online available data base. Human and mouse ccRCC cells were knocked-out for the NRP1 and NRP2 genes by a CRISPR/Cas9 method. Their proliferation and migration were evaluated by XTT or impedance tests and by wound closure. Production of VEGFA and VEGFC was evaluated by ELISA. Experimental ccRCC were performed in immuno-competent/deficient mice. The effects of a competitive inhibitor of NRP1, 2, NRPa-308, was tested in vitro and in vivo with the above-mentioned tests and on experimental ccRCC. NRPa-308 docking on both NRPs was performed.Results: Invalidation of the NRP1 and NRP2 genes inhibited cell proliferation and migration and stimulated the expression of VEGFA or VEGFC, respectively. NRPa-308 presented a higher affinity for NRP2 than for NRP1. It decreased cell proliferation and migration more efficiently than sunitinib and the commercially available NRP inhibitor EG00229. NRPa-308 presented a robust inhibition of experimental ccRCC growth in immunocompetent and immunodeficient mice in a reverse dose dependent manner. Such inhibition was associated with a decreased expression of several pro-tumoral factors. Analysis of the TCGA database showed that NRP2, more than NRP1 correlates with tumor aggressiveness only in metastatic patients.Conclusion: Our study strongly suggests that inhibiting NRP is a good therapeutic strategy for mccRCC patients in therapeutic impasses and NRPa-308 represents a relevant hit.

Abstract Background Previous studies reported that BATF played an important role in the progression of various cancers, but no report had been found on clear cell renal cell carcinoma(ccRCC). So we investigated the effects of BATF on the progression of ccRCC. Methods In this study, using TCGA-KIRC database from the Cancer Genome Atlas to analyze the differential genes of BATF in ccRCC ; using immunohistochemistry to detect BATF expression in 75 ccRCC tumorous and 28 nontumorous tissues, and investigate its relationship with clinicopathological parameters. Moreover, we constructed the cell lines of BATF overexpression and knockout in Caki-1and 786-0 ccRCC cell lines and confirmed by western blot. CCK8 assay was used to evaluated the cell viability and using EdU staining to detect cell proliferation; using Transwell experiment to investigate the affection of BATF in ccRCC cell migration. Westernblot was used to detect the phosphorylation of PI3K/AKT/mTOR. Results These results revealed that BATF expression in ccRCC tumorous was significantly higher compared with that in adjacent nontumorous tissues and was significantly correlated with T stage, Fuhrman grade, Tumor necrosis and status. In addiditon, BATF overexpression significantly inhibited the viability, proliferation and migration of the two cell lines. More importantly, using westernblot showed that silencing BATF significantly increased the level of phosphorylated AKT, PI3K and mTOR, while BATF overexpression decreased phosphorylation that involved in the PI3K/Akt/mTOR signaling pathway. Conclusions Our findings demonstrate that BATF plays an important role in the progression of ccRCC and it may act as an tumor supressor gene to inhibit the progression of ccRCC through regulating the PI3K/Akt/mTOR signaling pathway.

To investigate the underlying molecular mechanism of tripartite motif-containing 58 (TRIM58) in the development of clear cell renal cell carcinoma (ccRCC), we explored TRIM58 expression and methylation in tumor tissues and the association with clinicopathological features and prognosis of tissue samples; Moreover, we examined the direct gene transcription of TRIM58-specific DNA demethyltransferase (TRIM58-TET1) by the CRISPR-dCas9 fused with the catalytic domain of TET1 and the biological functions in RCC cells. In this study, we demonstrate that TRIM58 is frequently downregulated by promoter methylation in ccRCC tissues, associated significantly with tumor nuclear grade and poor patient survival. TRIM58-TET1 directly induces demethylation of TRIM58 CpG islands, and activates TRIM58 transcription in RCC cell lines. Besides, DNA demethylation of TRIM58 by TRIM58-TET1 significantly inhibits cell proliferation and migration Overall, our results demonstrate that TRIM58 is inactivated by promoter methylation, associates with tumor nuclear grade and poor survival, and TRIM58 DNA demethylation could directly activate TRIM58 transcription and inhibit cell proliferation and migration in RCC cell lines.
