Constitutive photomorphogenic 1 (COP1) belongs to the COP‑de-etiolated (DET)‑fusca (FUS) protein family and has been demonstrated to suppress prostate adenocarcinomas and other types of tumor, such as liver and gastric cancer. The present study investigated the expression of COP1 and its downstream factor, ets variant 1 (ETV1) in renal cell carcinoma (RCC) tissue samples, and evaluated the corr...

This aim of the present study was to observe the effect of high mobility group AT‑hook 2 (HMGA2) on the proliferation and invasion ability of ACHN renal cell carcinoma (RCC) cells. Human ACHN cells, an RCC cell line, and HKC normal human renal tubular epithelial cells were cultured. HMGA2 small interfering (si)RNA, Mock‑siRNA and their negative control group were designed and synthesized. Subse...

BACKGROUND Paclitaxel, a widely used chemotherapeutic drug, can induce apoptosis in variety of cancer cells. A previous study has shown preferential toxicity of paclitaxel to FLCN-deficient kidney cancer cell line, UOK257. In this report, we investigate the cellular and molecular mechanism of paclitaxel-induced autophagy and apoptosis in renal cancer cells with and without FLCN expression. ME...

Apigenin, a natural flavonoid found in vegetables and fruits, has antitumor activity in several cancer types. The present study evaluated the effects and mechanism of action of apigenin in renal cell carcinoma (RCC) cells. We found that apigenin suppressed ACHN, 786-0, and Caki-1 RCC cell proliferation in a dose- and time-dependent manner. A comet assay suggested that apigenin caused DNA damage...

PBRM1 is a novel tumor suppressor gene that can inhibit cancer cell proliferation and predict the outcome of renal cell carcinoma (RCC), but its biological role needs further elucidation. We examined expression of the PBRM1 gene in RCC cell lines and the effect of PBRM1 on cell proliferation and cell cycle in RCC ACHN cells. Microarray processing and analysis was used to explore novel pathways ...

The in vitro activity of ACHN-490, a novel aminoglycoside ("neoglycoside"), was evaluated against 102 multidrug-resistant (MDR) Klebsiella pneumoniae strains, including a subset of 25 strains producing the KPC carbapenemase. MIC50 values for gentamicin, tobramycin, and amikacin were 8 microg/ml, 32 microg/ml, and 2 microg/ml, respectively; MIC90 values for the same antimicrobials were > or = 64...

ACHN-490 was tested alone and in combination with cefepime, doripenem, imipenem, or piperacillin-tazobactam in a synergy time-kill analysis against 25 Pseudomonas aeruginosa strains with different resistance phenotypes. Each combination was synergistic against most isolates at 24 h, and antagonism was not observed. Combinations of ACHN-490 with cefepime, doripenem, imipenem, or piperacillin-taz...

BACKGROUND the emergence of carbapenemases in Enterobacteriaceae is driving a search for therapeutic alternatives. We tested ACHN-490, a sisomicin derivative that evades all plasmid-mediated aminoglycoside-modifying enzymes, against 82 carbapenem-resistant Enterobacteriaceae isolates. Comparators included internationally and locally available aminoglycosides. Methods The isolates variously had ...

Heat shock proteins (Hsps) are protective in models of transplantation, yet practical strategies to upregulate them remain elusive. The heat shock protein 90-binding agent (HBA) geldanamycin and its analogs (17-AAG and 17-DMAG) are known to upregulate Hsps and confer cellular protection but have not been investigated in a model relevant to transplantation. We examined the ability of HBAs to upr...

Abnormal expression of miRNAs contributed to cancers through regulation of proliferation, apoptosis and drug resistance of cancer cells. The present study was designed to investigate the effect of miR-497 on renal cell carcinoma (RCC) and its possible mechanism. Forty paired clear cell RCC (ccRCC) tissues and adjacent normal kidney tissues were obtained from patients, who were not treated by ch...
