  • Phellinus linteus (Hymenocaetaceae) is a member of Basidiomycotinae, which has been used for the treatment of gastric cancer, non-insulin-dependent diabetes mellitus, diarrhea, and menstrual irregularity. To investigate the diuretic action of Phellinus linteus, urinary volume, serum parameters and urinary electrolytes in HgCl$_2$-induced acute renal failure rats in vivo were measured. The results showed that its MeOH extract produced significant increases on urinary volume, sodium and potassium excretion, and revealed lowering effects of the abnormally elevated BUN, creatinine and uric acid value in acute renal failure rats.

  • Aconiti Tuber is a traditional medicinal plant generally used in Oriental medicine therapy. In this study, we investigated the biochemical mechanisms of anti-proliferative effects by the methanol extract of Aconiti tuber (MEBJ) in Caki-1 human renal cell carcinoma cells. It was found that MEBJ could inhibit, in a dose-dependent manner, cell growth which was associated with apoptotic cell death such as formation of apoptotic bodies, DNA fragmentation and increased populations of apoptotic-sub G1 phase. Apoptosis of Caki-1 cells by MEBJ was associated with an up-regulation of pro-apoptotic Bax expression, and a down-regulation of anti-apoptotic Bcl-2 in a dose-dependent manner; however, the levels of IAP family were not affected. MEBJ treatment also induced the proteolytic activation of caspase-3 and -8, and a inhibition of poly(ADP-ribose) polymerase (PARP) and $PLC{\gamma}1$ protein. Furthermore, MEBJ treatment caused a dose-dependent inhibition of iNOS and cyclooxygenase-2 (Cox-2). Though further studies will be needed to identify the active compounds that confer the anti-cancer activity of MEBJ, the present findings provide important new insights into the possible molecular mechanisms of the apoptotic activity of MEBJ in cancer cells.

  • Background: Relatively little is known with certainty about the status and role of p53 or MDM2 in predicting prognosis and survival of renal cell carcinoma. The present study aimed to determine the value of P53 and MDM2 over-expression, alone and simultaneously, to predict five-year survival of patients with kidney cancer in Iran. Materials and Methods: Patients with kidney cancer referred to Hasheminejad Kidney Center between 2007 and 2009, underwent radical nephrectomy and had pathology reports of clear cell, papillary or chromophobe renal cell carcinoma were included in our cohort study. Other histological types of renal cell carcinoma were not included. The patients with missed, incomplete or poor quality paraffin blocks were also excluded. Overall ninety one patients met the inclusion and exclusion criteria. To assess the histopathological features of the tumor, immunohistochemical (IHC) staining of formalin fixed, paraffin-embedded tumor samples were performed. The five-year survival was determined by the patients' medical files and telephone following-up. Results: In total, 1.1% of all samples were revealed to be positive for P53. Also, 20.8% of all samples were revealed to be positive for MDM2.The patients were all followed for 5 years. In this regard, 5-year mortality was 30.5% and thus 5-year survival was 85.3%. According to the Cox proportional hazard analysis, positive P53 marker was only predictor for patients' 5-year survival that the presence of positive p53 increased the risk for long-term mortality up to 2.8 times (HR=2.798, 95%CI: 1.176-6.660, P=0.020). However, the presence of MDM2 could not predict long-term mortality. In this regard, analysis by the ROC curve showed a limited role for predicting long-term survival by confirming P53 positivity (AUC=0.610, 95%CI: 0.471-.750, P=0.106). The best cutoff point for P53 to predict mortality was 0.5 yielding a low sensitivity (32.0%) but a high specificity (97.9%). In similar analysis, measurement of MDM2 positivity could not predict mortality (AUC=0.449, 95%CI: 0.316-.583, P=0.455). Conclusions: The simultaneous presence of both P53 and MDM2 markers in our population is a rare phenomenon and the presence of these markers may not predict long-term survival in patients who undergoing radical nephrectomy.

  • Lin28a has diverse functions including regulation of cancer, reprogramming and regeneration, but whether it promotes injury or is a protective reaction to renal injury is unknown. We studied how Lin28a acts in unilateral ureteral obstruction (UUO)-induced renal fibrosis following unilateral ureteral obstruction, in a mouse model. We further defined the role of Lin28a in transforming growth factor (TGF)-signaling pathways in renal fibrosis through in vitro study using human tubular epithelium-like HK-2 cells. In the mouse unilateral ureteral obstruction model, obstruction markedly decreased the expression of Lin28a, increased the expression of renal fibrotic markers such as type I collagen, α-SMA, vimentin and fibronectin. In TGF-β-stimulated HK-2 cells, the expression of Lin28a was reduced and the expression of renal fibrotic markers such as type I collagen, α-SMA, vimentin and fibronectin was increased. Adenovirus-mediated overexpression of Lin28a inhibited the expression of TGF-β-stimulated type I collagen, α-SMA, vimentin and fibronectin. Lin28a inhibited TGF-β-stimulated SMAD3 activity, via inhibition of SMAD3 phosphorylation, but not the MAPK pathway ERK, JNK or p38. Lin28a attenuates renal fibrosis in obstructive nephropathy, making its mechanism a possible therapeutic target for chronic kidney disease.

  • Measurement of quality of life among prostate cancer patients helps the health care providers to understand the impact of the disease in the patients' own perspective. The main aim of this study is to measure the quality of life among prostate cancer patients at University Malaya Medical Center (UMMC) and Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and to ascertain the association factors for physical coefficient summary (PCS) and mental coefficient summary (MCS). A hospital based, cross sectional study using the Short Form-36 (SF-36) questionnaire was conducted over a period of 6 months. A total of 193 respondents were recruited. Their total quality of life score was $70.1{\pm}14.7$ and the PCS score was lower compared to MCS. The factors associated for PCS were: age, living partner, renal problem, urinary problem of intermittency, dysuria and hematuria. Factors associated for MCS were: age, living partner, renal problem, presenting prostatic specific antigen and urinary problem of intermittency and dysuria. Our prostate cancer patients had moderate quality of life in the physical health components but their mental health was less affected.

  • Non small cell lung cancer (NSCLC) frequently metastasizes to brain, bone, liver, and adrenal glands. While an autopsy of NSCLC reveals some cases of metastasis to the kidney, clinical detection of renal metastases is extremely rare. Furthermore, metastases to the kidney usually present as multifocal or bilateral lesions and solitary renal metastases are usually suspected to be renal cell carcinoma. We now report a case of asymptomatic solitary renal metastasis from a primary squamous cell carcinoma, which was detected by routine surveillance with abdominal CT after curative surgery.

  • Cisplatin is often effective in cancer treatment, but its clinical use is limited because of its nephrotoxicity. We have synthesized new platinum(II) coordination complexes (PC-1 & PC-2) containing trans-${\iota}$ and cis-1,2-diaminocyclohexane (DACH) as carrier ligands and L-3 -phenyllactic acid (PLA) as a leaving group with the aim of reducing nephrotoxicity but maintaining its anticancer activity. In this study, new platinum(II) complex compounds were evaluated for selective cytotoxicity on cancer cell-lines and normal kidney cells. The new platinum complexes have demonstrated high efficacy in the cytotoxicity against human bladder carcinoma cell-lines (T-24/HT-1376). The cytotoxicity of these compounds against rabbit proximal renal tubular cells and human renal cortical tissues, was determined by MTT assay, the [3H]-thymidine uptake and glucose consumption test, and found to be quite less than those of cisplatin. Based on our results, these novel platinum compounds appear to be valuable lead compounds with high efficacy and low nephrotoxicity.

  • Aims: To evaluate anti-cancer activity of Asparagus racemosus (AR) leaf extract on UOK146, a renal cell carcinoma cell line, and explore its mechanism of action. Materials and Methods: Dried AR leaves were extracted with chloroform and dissolved in DMSO. This extract was applied to UOK146 and cell death was estimated by MTT assay. In addition PRCC-TFE3 fusion transcripts were detected by real time PCR. Results: Extract was found to be cytotoxic with an $IC_{50}$ of 0.9 mg/ml as estimated by dose response curve. Antitumor activity of the permissible doses of the extract was assessed by the down regulation of PRCC-TFE3 fusion transcript (38%) responsible for oncogenicity of the UOK146 cell line. No increment in the BAX, a proapoptotic marker level was observed. Conclusions: Evidence of antiproliferative effect, PRCC-TFE3 fusion transcript inhibition and static BAX level clearly indicate that AR extract provides or elicits an apoptosis independent anticancer effect on RCC cells by some specific mechanism of regulation.

  • Patients in end-stage renal disease (ESRD) and chronic renal failure present a number of challenges to the anesthesiologist. They may be chronically iii and debilitated and have the potential for multiorgan dysfunction. A 65-year-old male patient with ESRD was scheduled for oral cancer surgery under general anesthesia. He was in regular hemodialysis three times a week and secondary hypertension with left ventricular hypertrophy was accompanied. He also had chronic metabolic acidosis and hyperkalemia. The day after hemodialysis, general anesthesia was carried out. Uneventful anesthetic induction using thiopental and vecuronium and nasotracheal intubation were carried out. General anesthesia was maintained with isoflurane for 9 hours. During the anesthesia, he did not have any problem but persistently increasing serum potassium level. After anesthetic emergence, he was transferred to intensive care unit for mechanical ventilation. So we report this successful case of anesthetic management in a patient with ESRD for oral cancer surgery, which massive bleeding and long anesthetic time were inevitable in, from the preoperative preparation to anesthetic emergence.
