Tumor growth and metastasis are dependent on angiogenesis. The overexpression of integrin αvβ3 on angiogenic vessels and on numerous malignant human tumor cells suggests that these labeled ligands of integrin are potentially suitable for molecular imaging and in targeted therapy of tumors. In previous studies, we added a β-lactamase variant with reduced immunogenicity to the cyclic peptide RGD4C, resulting in the fusion protein RGD4CβL, which is suitable for use in targeted enzyme prodrug therapy (TEPT), a promising treatment for tumors...

Melanoma is an aggressive malignancy that is increasingly common and exhibits a poor patient survival rate. Radiotherapy is the primary option for patients with melanoma, particularly those who are not candidates for surgery; however, the therapeutic effect is limited due to the relative radioresistance of melanoma to ionizing radiation (IR). It has been reported that microRNAs (miRNAs) serve a vital role in determining the radiosensitivity of tumors; however, little is known concerning the radiosensitization of melanoma using miRNA...

The aim of the present study was to explore use of the acridine orange fluorescence (AO-F) staining method for screening of circulating tumor cells (CTCs) in renal cell carcinoma (RCC) patients. The AO-F positive staining rate of live and dead tumor cells was calculated. The positive staining rate in the live group was 93.4±3.0%, while the dead group failed to emit specific fluorescence. A known number of tumor cells were added to peripheral blood, and the detection sensitivity of the four groups (50, 100, 200 and 500 cells/tube) was 10...

An accumulation of driver mutations is important for cancer formation and progression, and leads to the disruption of genes and signaling pathways. The identification of driver mutations and genes has been the subject of numerous previous studies. The present study was performed to identify cancer-driving mutations and genes in renal cell carcinoma (RCC), prioritizing noncoding variants with a high functional impact, in order to analyze the most informative features. Sorting Intolerant From Tolerant (SIFT), Polymorphism Phenotyping version 2 (Polyphen2) and MutationAssessor were applied to predict deleterious mutations in the coding genome...

Clear cell renal cell carcinoma (ccRCC) is the most common type of neoplasm affecting the adult kidney. Previous studies on ccRCC have focused on microRNAs, a class of small non-coding RNAs that are important in cancer development and progression. The present study aimed to investigate the potential role of microRNA (miR)-30e-3p in ccRCC. The results revealed that overexpression of miR-30e-3p in the A498 and 786O ccRCC cell lines was able to inhibit cell invasion and migration. The expression level of Snail1, a potential target gene of miR-30e-3p, was inversely correlated with miR-30e-3p expression in ccRCC tissues and cell lines...

Sarcomatoid urothelial carcinoma of the urinary tract is associated with poor prognosis. The majority of sarcomatoid urothelial carcinomas are found in the urinary bladder, while a small minority have been shown to arise from the ureter. In the present case, a 72-year-old male patient was diagnosed with sarcomatoid urothelial carcinoma with chondrosarcomatous differentiation of the left ureter, and subsequently underwent nephroureterectomy and retroperitoneal lymph node dissection. Two lymph nodes from the renal hilum and one paraaortic lymph node were also found to have metastatic involvement; however, the patient refused to receive chemotherapy or radiotherapy and succumbed to bone and omentum metastasis at 6 months after the initial diagnosis...

Gemcitabine is frequently used for the treatment of a number of different cancer types. Gemcitabine-related thrombotic microangiopathy (TMA) has rarely been described, but it is a life-threatening complication. The incidence of the complication varies between 0.015 and 1.4%. The present study reports the case of a 63-year-old Caucasian male who was treated with 3 cycles of carboplatin plus gemcitabine, followed by 7 cycles of gemcitabine only, and developed clinical symptoms that, together with laboratory findings, were compatible with a diagnosis of hemolytic uremic syndrome TMA...

Mixed cryoglobulinemia syndrome (MC) is a systemic vasculitis involving kidneys, joints, skin, and peripheral nerves. While many autoimmune, lymphoproliferative, and neoplastic disorders have been associated with this disorder, hepatitis C virus (HCV) is known to be the etiologic agent in the majority of patients. Therefore, clinical research has focused on anti-viral drugs and, more recently, on the new, highly potent Direct-acting Antiviral Agents (DAAs). These drugs assure sustained virologic response (SVR) rates >90%...

Peroxiredoxin 6 (PRDX6) is a member of the PRDX family of antioxidant enzymes and correlated with inflammatory response. Therefore, we investigated the role of PRDX6 during lipopolysaccharide (LPS)-induced acute kidney injury. Both 3 months aged PRDX6-overexpressing transgenic mice (PRDX6 mice) and wild type (WT) mice had acute renal injury induced by intraperitoneal injection of LPS (10 mg/kg)., PRDX6 mice showed decreased mortality and renal injury following LPS challenge compared to WT mice. Furthermore, infiltration of macrophages, T-cells and neutrophils, and the number of apoptotic cells were more decreased by LPS treatment in PRDX6 mice than in WT mice...

METHODS: Between 2003 and 2014, 11 MRI were performed on fetuses (between 28-32 weeks) in whom second trimester sonography suggested severe bilateral urinary tract anomalies, suspected of PUV. RESULTS: The ADC of the 11 fetuses ranged from 1.3 to 2.86 mm2 s - 1 (median = 1.79 mm2s - 1, normal range for fetal kidney: 1.1-1.8). Two pregnancies with ADC > 2.6 mm2s - 1 were interrupted; the autopsy confirmed PUV and Potter syndrome. For the remaining nine babies, the follow-up was 5...
