The von Hippel-Lindau (VHL) gene is often inactivated in sporadic renal cell carcinoma (RCC) by mutation or promoter hypermethylation. The prognostic or predictive value of VHL gene alteration is not well established. We conducted this meta-analysis to evaluate the association between the VHL alteration and clinical outcomes in patients with RCC. We searched PUBMED, MEDLINE and EMBASE for articles including following terms in their titles, abstracts, or keywords: 'kidney or renal', 'carcinoma or cancer or neoplasm or malignancy', 'von Hippel-Lindau or VHL', 'alteration or mutation or methylation', and 'prognostic or predictive'...

Over the past decade metastatic renal cell carcinoma (RCC) treatment landscape has dramatically evolved from the era of cytokines-based immunotherapy (which benefited very few patients, at the expenses of high toxicities) to the present era of targeted agents and novel immunotherapeutics, greatly improving the prognosis of our patients. Areas covered: Here we have reviewed the present status of the medical treatment of metastatic RCC. To do this, we interrogated the Medline database, as well as the proceedings of the main Oncological and Urological conferences for the relevant trials coducted so far...

BACKGROUND: The prevalence of sickle cell trait is extremely high in sub-Saharan Africa. Recent studies have reported the impact of sickle cell carriers on renal function. However, data on renal abnormalities in children with sickle cell trait in this part of the world are unknown. In this report, we assess the glomerular function of children with sickle cell trait (SCT). METHODS: A case control study was conducted to assess the glomerular function in 43 Congolese children with sickle cell trait (Hb-AS) matched for age to 65 children with sickle cell anemia in steady state (Hb-SS) and 67 normal controls (Hb-AA)...

BACKGROUND: Cystic fibrosis is a common life-shortening genetic disorder in the Caucasian population (less common in other ethnic groups) caused by the mutation of a single gene that codes for the production of the cystic fibrosis transmembrane conductance regulator protein. This protein coordinates the transport of salt (and bicarbonate) across cell surfaces and the mutation most notably affects the airways. In the lungs of people with cystic fibrosis, defective protein results in a dehydrated surface liquid and compromised mucociliary clearance...

BACKGROUND: The targeting of the prostate-specific membrane antigen (PSMA) is of particular interest for radiotheragnostic purposes of prostate cancer. Radiolabeled PSMA-617, a 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA)-functionalized PSMA ligand, revealed favorable kinetics with high tumor uptake, enabling its successful application for PET imaging ((68)Ga) and radionuclide therapy ((177)Lu) in the clinics. In this study, PSMA-617 was labeled with cyclotron-produced (44)Sc (T 1/2 = 4...

Human podoplanin (hPDPN), which binds to C-type lectin-like receptor-2 (CLEC-2), is involved in platelet aggregation and cancer metastasis. The expression of hPDPN in cancer cells or cancer-associated fibroblasts indicates poor prognosis. Human lymphatic endothelial cells, lung-type I alveolar cells, and renal glomerular epithelial cells express hPDPN. Although numerous monoclonal antibodies (mAbs) against hPDPN are available, they recognize peptide epitopes of hPDPN. Here, we generated a novel anti-hPDPN mAb, LpMab-21...

Patients with suspected hereditary renal cell cancer (RCC) are under-referred for genetic evaluation. Characterizing the prevalence and characteristics of suspected inherited RCC is a crucial step toward advancing personalized, genetically-based cancer risk management for patients and their families. To evaluate the prevalence and characteristics of suspected inherited RCC syndromes based on consensus criteria, we performed a cross-sectional analysis of patients with a diagnosis of RCC in SEER (2001-2011, n = 105,754) and in our institutional cancer registry (2004-2013, n = 998)...

Pregnancy-associated thrombotic microangiopathy is a very rare condition; however, it significantly increases fetal or maternal morbidity and mortality. Pregnancy may trigger atypical hemolytic uremic syndrome (aHUS) or thrombotic thrombocytopenic purpura. The risk for pregnancy-associated aHUS is highest during the second pregnancy. The outcome is usually poor with 50-60% mortality; renal dysfunction and hypertension are the rule in those who survive the acute episode. After the development of complement regulation mechanisms and aHUS pathogenesis, eculizumab has been widely used as a first-line treatment in aHUS...

Patients with gastrointestinal bleeding often require large volume blood transfusion. Among the various side effects of blood transfusion, the increase of potassium levels is a serious one which is often overlooked. We report a case of severe hyperkalemia in a patient with gastric bleeding after large volume transfusion of packed red blood cells. The patient had hyperkalemia at baseline associated with his receiving medication as well as acute renal failure following hypovolemia. The baseline hyperkalemia was further aggravated after massive transfusions of packed red blood cells in a short period of time...

Combination therapy with S-1 and cisplatin (CDDP) is the standard chemotherapy for advanced gastric cancer in Japan; however, its administration requires hospitalization for hydration to prevent nephrotoxicity from CDDP. By contrast, NC-6004 appears to reduce the renal toxicity of CDDP and may be used on an outpatient basis. Thus, the effects of combined treatment with S-1 and NC-6004 were compared with those of S-1 and CDDP in a human gastric cancer model. In vitro cytotoxic effects were investigated in 44As3Luc, MKN45 and MKN74 human gastric cancer cell lines...

Deficiency in vitamin D and its active metabolite is a characteristic of chronic kidney diseases (CKDs). Previous studies have reported that 1α,25-dihydroxyvitamin D3 [1,25(OH)2D3], the active form of vitamin D, can attenuate renal interstitial fibrosis. The present study aimed to explore the effect of 1,25(OH)2D3 on the transdifferentiation of NRK-52E rat renal tubular epithelial cells (RTECs) induced by high glucose, as well as the expression of vitamin D receptor (VDR) and production of angiotensin (Ang) II...

Acyclovir has been a frequently used antiviral agent in the clinical treatment of leukemia, acute encephalitis, malignant tumor and herpes simplex. The adverse effects of this drug have been widely described in clinical practice. In the present study, a case of a 35-year-old female patient diagnosed with herpes simplex, who developed acute renal injury following treatment with valacyclovir hydrochloride, is described. Kidney biopsy, light microscopy and laboratory examination were performed, and all findings revealed the signs of evident vacuolar degeneration of capillary endothelial and renal tubular epithelial cells, erythrocyte aggregation in partial renal tubule and microvilli exfoliation from epithelial cells...

Soluble ligands have commonly been targeted by antibody therapeutics for cancers and other diseases. While monoclonal antibodies targeting such ligands can block their interactions with their cognate receptors, they can also significantly increase the half-life of their ligands by FcRn-mediated antibody recycling, thereby evading ligand renal clearance and requiring increasingly high antibody doses to neutralize the increasing pool of target. To overcome this issue, we generated a bispecific/biparatopic antibody (BiSAb) that targets two different epitopes on IL-6 to block IL-6 mediated signaling...

It is well-recognized that Murine Double Minute gene 2 (MDM2) plays a critical role in cell proliferation and inflammatory processes during tumorigenesis. Also it is reported that MDM2 is expressed in glomeruli and involved in podocyte injury. However, whether MDM2 is implicated in renal fibrosis remains unclear. Here we investigated the role of MDM2 in tubulointerstitial fibrosis (TIF). By immunohistochemical staining and western blotting we confirmed that MDM2 is up-regulated in tubulointerstitial compartment in TIF patients and Unilateral Urethral Obstruction (UUO) mice, which mainly originates from myofibroblasts...

In 2015, as part of the Reproducibility Project: Cancer Biology, we published a Registered Report (Kandela et al., 2015) that described how we intended to replicate selected experiments from the paper "Discovery and Preclinical Validation of Drug Indications Using Compendia of Public Gene Expression Data" (Sirota et al., 2011). Here we report the results of those experiments. We found that cimetidine treatment in a xenograft model using A549 lung adenocarcinoma cells resulted in decreased tumor volume compared to vehicle control; however, while the effect was in the same direction as the original study (Figure 4C; Sirota et al...

Cardiac glycosides are well known in the treatment of cardiovascular diseases; however, their application as treatment option for cancer patients is under discussion. We showed that the cardiac glycoside digitoxin and its analog AMANTADIG can inhibit the growth of renal cell carcinoma (RCC) cell lines and increase G2/M cell cycle arrest. To identify the signaling pathways and molecular basis of this G2/M arrest, microRNAs were profiled using microRNA arrays. Cardiac glycoside treatment significantly deregulated two microRNAs, miR-2278 and miR-670-5p...

The most efficient sequence of targeted agents for metastatic renal cell carcinoma patients has yet to be identified. Whether the sequence of sorafenib and sunitinib really matters is controversial and not answered clearly until now. This meta-analysis aims to estimate the efficacy of receptor tyrosine kinase inhibitors sorafenib-sunitinib and sunitinib-sorafenib for metastatic renal cell carcinoma, on the outcome of first-line progression-free survival, second-line progression-free survival, total progression-free survival and overall survival...
