Renal cell carcinoma (RCC) is the most common kidney malignancy with poor prognosis. Recently, long noncoding RNAs (lncRNAs) have been demonstrated as important regulators in multiple cancers including RCC. LOC653786 is a lncRNA, but its role in cancer remains unclear. In this study, we for the first time found that LOC653786 was upregulated in RCC tissues and cell lines, and this lncRNA promoted growth and cell cycle progression of RCC cells. Moreover, we showed that LOC653786 elevated the expression of forkhead box M1 (FOXM1) and its downstream target genes cyclin D1 and cyclin B1 in RCC cells...

Cutaneous melanoma is one of the cancers with the fastest rising incidence and in its advanced metastatic form is a highly lethal disease. Despite the recent approval of several new drugs, the 5-year overall survival rate for advanced cutaneous melanoma is still below 20% and therefore, the development of novel treatments remains a primary need. Antibody-Drug Conjugates are an emerging novel class of anticancer agents, whose preclinical and clinical development has recently seen a remarkable increase in different tumors, including melanoma...

BACKGROUND: Early postoperative acute kidney injury (AKI) is associated with increased morbidity and mortality following major surgery. Only few reports exist on postoperative AKI and specifically its risk factors after radical cystectomy (RC) and urinary diversion (UD). We aimed to identify risk factors for AKI in patients undergoing RC and UD. METHODS: In an observational single-center cohort study, 912 consecutive bladder cancer patients undergoing RC and UD from 2000 to 2016 were evaluated for risk factors for AKI...

Apatinib, a highly selective small-molecule inhibitor of vascular endothelial growth factor receptor-2 (VEGFR-2), has attracted many attentions due to its anticancer activity in various malignancies containing non-small-cell lung cancer (NSCLC). Our previous preclinical study confirmed the enhanced anti-tumor efficacy of combined treatment between apatinib and docetaxel for NSCLC. However, the effects of docetaxel on pharmacokinetics and tissue distribution of apatinib are not clear. In present study, a reliable HPLC-MS/MS method was established for determination of apatinib...

OBJECTIVES: A small subset of patients treated with immune checkpoint inhibitors manifest atypical patterns of response, the so-called pseudoprogression (PP) and hyperprogression (HP). Their prevalence in urothelial (UC) and renal cancer (RCC) remains, to date, mostly uninvestigated. Therefore, we aimed to provide a summary of the current knowledge about PP and HP during immune checkpoint inhibitor therapy in UC and RCC patients. METHODS AND MATERIALS: A systematic medline/pubmed© literature search was performed...

Organic anion-transporting polypeptides (OATPs; gene symbol SLCO) are membrane transporters that mediate the transport of wide ranges of compounds. Expression of different OATP members has been reported in the kidney, liver, placenta, brain, and intestine. Due to their broad substrate spectra and wide distribution within human body, these transporters have been proposed to play key roles in the influx transport of many oral drugs. Inflammation is known to regulate the expression and functions of many drug-metabolizing enzymes and drug transporters...

BACKGROUND: Birt-Hogg-Dubé syndrome is a genetic syndrome caused by mutations in the FLCN gene. The main symptoms are lung bullae and pneumothorax, benign and malignant kidney tumors, and facial fibrofolliculoma. The risk of pneumothorax is considerable between ages 20-40 years, but decreases markedly after this age range and first-time pneumothorax after age 50 years is rare. Fibrofolliculomas usually occur between ages 35 and 45 years, while the risk for kidney cancer increases steadily with age, starting in young adulthood...

Tumour lysis syndrome (TLS) is a rare oncological emergency in solid tumours. Because it is associated with bad short-term prognosis, early recognition and treatment are mandatory. This case refers to a middle-aged woman who presented with stage IV colon cancer, with massive hepatic involvement. After three cycles of first-line FOLFOX (folinic acid, 5-fluorouracil and oxaliplatin), she developed acute kidney injury and hyperkalaemia that did not respond to standard measures. High suspicion of TLS prompted further corroborating investigations and early intensive care unit admission...

BACKGROUND: Endoglin (CD105) is overexpressed on tumor cells and tumor vasculatures, making it a potential target for diagnostic imaging and therapy of different neoplasms. Therefore, studies on nanocarrier systems designed for endoglin-directed diagnostic and drug delivery purposes would expose the feasibility of targeting endoglin with therapeutics. METHODS: Liposomes carrying high concentrations of a near-infrared fluorescent dye in the aqueous interior were prepared by the lipid film hydration and extrusion procedure, then conjugated to single chain antibody fragments either selective for murine endoglin (termed mEnd-IL) or directed towards human endoglin (termed hEnd-IL)...

PURPOSE: PSMA-targeted PET in patients with prostate cancer (PCa) has a significant impact on treatment decisions. By far the most frequently used PSMA ligand is68 Ga-labelled PSMA-11. However, due to the availability of larger amounts of activity,18 F-labelled PSMA ligands are of major interest. The aim of the present study was to evaluate the biodistribution and performance of the novel18 F-labelled ligand PSMA-1007 at two different time points. METHODS: This retrospective analysis included 40 consecutive patients (mean age 68...

Although gastric metastases have been estimated to occur in less than 2% of cancer patients, an increased use of upper digestive tract endoscopy allows for a higher detection of secondary gastric tumors. We describe the case of a 66-year-old male patient presenting with mild pain in the sternum and upper abdominal area. Physical examination revealed a right parietal skull tumor, with no other significant clinical changes. Upon exclusion of an acute coronary syndrome, upper digestive tract endoscopy was performed, showing the presence of an ulcerated tumor located in the gastric fundus...

Background: Asparaginyl endopeptidase, also known as legumain (EC shows strong activity in the mouse kidney. Legumain is also highly expressed in tumors. DJ-1/PARK7 is a Parkinson's disease- and cancer-associated protein. DJ-1 is a coactivator of various transcription factors. Recently, we reported that transcription of the legumain gene is regulated by p53 through DJ-1. Methods: We measured the secretion levels of legumain in a conditioned medium of DJ-1 knockout cells and in serum from DJ-1 knockout mice using Western blotting and ELISA...

Cancer stem cells (CSCs) are essentially responsible for tumor initiation, growth, progression, metastasis and recurrence, and cigarette smoke (CS) is closely involved in the occurrence and development of kidney cancer. However, the effect of CS on renal CSCs has not been elucidated yet. In the present study, tumorsphere formation assay was used to enrich renal CSCs from 786-O and ACHN cells. We illustrated that CS effectively promoted renal CSCs stemness by enhancing tumorsphere formation, increasing the expression of renal CSCs markers (CD133, CD44, ALDHA1, Oct4, and Nanog) and elevating CD133+ cell population...

Fibroblast growth factor (FGF)/FGF receptor (FGFR) signaling facilitates tumor initiation and progression. Although currently approved inhibitors of FGFR kinase have shown therapeutic benefit in clinical trials, over-expression or mutations of FGFRs eventually confer drug resistance and thereby abrogate the desired activity of kinase inhibitors in many cancer types. In this study, we report that loss of myristoylation of fibroblast growth factor receptor substrate 2 (FRS2α), a scaffold protein essential for FGFR signaling, inhibits FGF/FGFR-mediated oncogenic signaling and FGF10-induced tumorigenesis...

Endometriosis and adenomyosis are histologically defined. The frequency of endometriosis cannot be precisely estimated in the general population. Endometriosis is considered a disease when it causes pain and/or infertility. Endometriosis is a heterogeneous disease with three well-recognized subtypes that are often associated with each other: superficial endometriosis (SUP), ovarian endometrioma (OMA), and deep infiltrating endometriosis (DIE). DIE is frequently multifocal and mainly affects the following structures: the uterosacral ligaments, the posterior vaginal cul-de-sac, the bladder, the ureters, and the digestive tract (rectum, recto-sigmoid junction, appendix)...

Fatigue, a commonly reported symptom, is defined as an overwhelming, debilitating, and sustained sense of exhaustion that decreases the ability to function and carry out daily activities. To date, cancer researchers have been in the forefront in investigating the possible biological mechanisms of fatigue, identifying inflammation, dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, and activation of the autonomic nervous system. The purpose of this systematic review is to describe fatigue and what is known about the biological mechanisms described in cancer in five chronic, noninfectious illnesses: heart failure, multiple sclerosis, chronic kidney disease, rheumatoid arthritis, and chronic obstructive pulmonary disease...

Papillary renal cell carcinomas (PRCC) are a histologically and genetically heterogeneous group of tumors that represent 15-20% of all kidney neoplasms and may require diverse therapeutic approaches. Alteration of the NF2 tumor suppressor gene, encoding a key regulator of the Hippo signaling pathway, is observed in 22.5% of PRCC. The Hippo signaling pathway controls cell proliferation by regulating the transcriptional activity of Yes-Associated Protein, YAP1. Loss of NF2 results in aberrant YAP1 activation...
