Clear cell renal cell carcinoma (ccRCC) is a common pathological subtype of renal cancer. Although the recent application of molecular-targeted agents has modestly improved the prognosis of ccRCC patients, their outcome is still poor. It is therefore important to characterize the molecular and biological mechanisms responsible for the development of ccRCC. Approximately 25% ccRCC patients involves the loss of RNA-binding protein QKI at 6q26, but the role of QKI in ccRCC is unknown. Here, we found that QKI-5 was frequently downregulated in ccRCC patients and its down-regulation was significantly associated with clinical features including T status, M status, and differentiation grade, and poorer patient prognosis...

The incidence and prevalence of paraneoplastic glomerulopathy, especially associated with carcinoma, are a matter of debate and the causal link between cancer and glomerular diseases remains unclear. The aim of this study was to evaluate renal biopsies of selected bitches with spontaneous mammary gland carcinoma. We hypothesized that dogs with mammary carcinomas would show histologic evidence of glomerular pathology. A prospective study was performed in dogs with naturally occurring mammary carcinoma that were undergoing tumor resection and ovariohysterectomy...

: An increase in the incidence of second primary cancers (SPC) is the late effect of greatest concern that could occur in differentiated thyroid carcinoma (DTC) patients treated with radioactive iodine (RAI). The decision to treat a patient with RAI should therefore incorporate a careful risk-benefit analysis. The objective of this work is to adapt the risk estimation models developed by the Biological Effects of Ionizing Radiation Committee (BEIR VII) to local epidemiological characteristics, to assess the carcinogenesis risk from radiation in a population of Brazilian DTC patients treated with RAI...

Calcitonin Gene-related Peptide (CGRP), Vasoactive Intestinal Peptide (VIP) and Substance P (SP) are sensory neuropeptides which may alter cancer growth through modulation of chronic inflammation. We recently reported that SP suppresses breast cancer growth and metastasis through neuroimmune modulation. These neuropeptides are hydrolyzed by Neprilysin (NEP) to bioactive fragments. Decreased activity of NEP was reported in clear cell and chromophobe type renal cell carcinoma (RCC). It is however not known how the levels of neuropeptides hydrolyzed with NEP changes in RCC...

The identification of markers for disease diagnostic, prognostic, or predictive purposes will have a great effect in improving patient management. Proteomic‑based approaches for biomarker discovery are promising strategies used in cancer research. In this study, we performed quantitative proteomic analysis on four patients including clear cell renal cell carcinoma (ccRCC) and paired adjacent non‑cancerous renal tissues using label‑free quantitative proteomics and liquid chromatography‑tandem mass spectrometry (LC‑MS/MS) to identify differentially expressed proteins...

Renal cell carcinoma (RCC) comprises 2‑3% of all malignant tumors in adults. Many studies have established the key roles of smoking, hypertension and other components of metabolic syndrome in the occurrence of RCC. Diabetes mellitus (DM), one of the main consequences of metabolic syndrome, appears much more often in patients with RCC. The prognosis for patients suffering from both diabetes and RCC is worse than for those with kidney cancer only. Diabetes is linked to higher rate of recurrence and a greater number of distant metastases...

AIMS: Sorafenib, which has been used extensively for the treatment of renal cell cancer and advanced hepatocellular carcinoma (HCC), has also been shown to have antifibrotic effects in liver fibrosis. However, the effects of sorafenib on renal fibrosis are unknown. Therefore, we investigated whether sorafenib inhibited renal fibrosis in a mouse model of unilateral ureteral obstruction (UUO) and further explored the potential mechanism. METHODS: Mice underwent UUO followed by vehicle or sorafenib treatment...

BACKGROUND: Due to demographic projections, and lack of an algorithm in the case of a prostate specific antigen (PSA)-positive donor, the loss of organ recovery may occur more frequently in the near future without approved procedures. In Poland in recent years it has been recommended to determine tumor markers in potential donors. In the first year of the recommendation 10% of potential deceased donors were disqualified in our transplantation center on the basis of the elevated PSA levels (high PSA >10 ng/mL)...

Multiple Endocrine Neoplasia (MEN) is a condition in which several endocrine organs of an individual are affected by adenoma, hyperplasia and less often carcinoma, either simultaneously or at different stages of life. Two existing syndromes, MEN1 and MEN2 (2A, 2B), in literature is also mentioned MEN4, are associated also with other non-endocrine disorders. MEN1 (Wermer syndrome) affects the pituitary, parathyroid, and pancreatic area. 95 % of patients show very early manifestation of hyperparathyroidism, often before 40 years of age...
