Rocaglamide has been reported to sensitize several cell types to TRAIL-induced apoptosis. In recent years, advances in synthetic techniques have led to generation of novel rocaglamide analogs. However, these have not been extensively analyzed as TRAIL sensitizers, particularly in TRAIL-resistant renal cell carcinoma cells. Evaluation of rocaglamide and analogs identified 29 compounds that are able to sensitize TRAIL-resistant ACHN cells to TRAIL-induced, caspase-dependent apoptosis with sub-µM potency which correlated with their potency as protein synthesis inhibitors and with loss of cFLIP protein in the same cells...

Metastatic renal cell carcinoma (mRCC) is a tumor entity with poor prognosis due to limited therapy options. Tyrosine kinase inhibitors (TKIs), the novel targeted agents have been used for the treatment of mRCC and have shown efficacy. Interferon (IFN)-α is also one of the most frequently used agents in immunotherapy. However, drug resistance needs to be overcome to achieve a sufficiently positive effect. Interleukin-6 (IL-6), which induce suppressor of cytokine signaling-3 (SOCS3) expression, is one of the factors associated with poor prognosis of patients with renal cell carcinoma (RCC)...

Recently, long noncoding RNA have been identified as new gene regulators and prognostic biomarkers in various cancers, including renal cell carcinoma (RCC). The expression and biological roles of LINC00961 have been reported in many human cancers. However, up to date, no study of LINC00961 has been shown in RCC. Currently, we aimed to investigate the function of LINC00961 in RCC progression. Interestingly, we observed that LINC00961 could act as a novel biomarker in predicting the diagnosis of RCC. Then, we found that LINC00961 was greatly downregulated in RCC cell lines (Caki-1, Caki-2, 786-O, A498, and ACHN cells) compared with normal renal cell lines (HK-2 cells)...

The majority of clear cell renal cell carcinomas (ccRCCs) are caused by an accumulation of hypoxia‑inducible factor (HIF) and the overexpression of downstream genes in response to the von Hippel‑Lindau (VHL) gene becoming inactivated. In the present study, our hypothesis was that BNIP3, a gene positioned downstream of HIF, would be expressed at a higher level in ccRCC; however, instead, lower levels of BNIP3 expression were identified in RCC tumor tissues compared with adjacent non‑tumor tissues. These changes were associated with lower levels of VHL, and higher levels of HIF and vascular endothelial growth factor...

The aim of the present study was to investigate the role of microRNA (miR)‑222‑3p in renal cell carcinoma (RCC). The expression level of miR‑222‑3p was detected in RCC tissues and cell lines (ACHN, 786‑O, Caki‑1 and 769‑P) and was identified to be significantly upregulated compared with the level in adjacent normal renal tissues and HK‑2 cells. Further in vitro experiments demonstrated that the over-expression of miR‑222‑3p promoted the migration and invasion, and attenuated the apoptosis of 786‑O cells, whereas the knockdown of miR‑222‑3p suppressed the migration and invasion and induced the apoptosis of 786‑O cells...

Metastatic Renal cell carcinoma (RCC) remains a difficult oncologic challenge. Salinomycin is a monocarboxylic polyether antibiotic, which has been proved to possess anti-tumor activities in multiple types of cancer cells. However, its effects on RCC cells remains unclear. In our study, salinomycin could inhibit the proliferation and viability of RCC cell lines 786-O and ACHN. The TUNEL assay revealed that treatment with salinomycin induced DNA breaking in RCC cells. Consistently, Western blotting showed up-regulation of pro-apoptotic biomarkers (cleaved caspase3/9 and cleaved PARP1) and down-regulation of anti-apoptotic biomarker (survivin) in RCC cells after salinomycin treatment, suggesting that salinomycin could induce RCC cell apoptosis...

Thymoquinone (TQ, 2-methyl-5-isopropyl-1,4-benzoquinone), a bioactive constituent extracted from the seeds of Nigella sativa, has been proved to exert anti-tumor efficiency in various cancers. Autophagy is a self-digestion phenomenon, and its role in tumor formation and progression remains controversial. In the present study, we investigated the effects of TQ on renal cell cancer (RCC) cell lines (786-O and ACHN) using wound healing assay, transwell assay and western blot analysis. We found that TQ effectively inhibited the metastatic capacity of RCC cells in vitro, which was also verified in a xenograft model...

Renal cell carcinoma (RCC) is the third most common urological malignancy in the USA and represents 2‑3% of all adult malignancies. Furthermore, the incidence of RCC has been progressively increasing over recent years. Although the morbidity of treatment has decreased with the use of multidisciplinary synthetic therapy, the prognosis of terminal cancer remains poor, with a 5‑year survival rate of 5‑10%. MicroRNAs (miRs) have been correlated with the regulation of 30‑60% of the protein-coding genes and act as oncogenes or anti‑oncogenes in RCC...
