Circulating miRNAs have shown great promises as non-invasive diagnostic and predictive biomarkers in several solid tumors. While the miRNA profiles of renal tumors have been extensively explored, knowledge of their circulating counterparts is limited. Our study aimed to provide a large-scale genome-wide profiling of plasma circulating miRNA in clear-cell renal cell carcinoma (ccRCC). Plasma samples from 94 ccRCC cases and 100 controls were screened for 754 circulating micro-RNAs (miRNA) by TaqMan arrays. Analyses including known risk factors for renal cancer, namely age, sex, hypertension, obesity, diabetes, tobacco smoking and alcohol consumption, highlighted that circulating miRNA profiles were tightly correlated with the stage of the disease...

Prostate-specific membrane antigen (PSMA) continues to be an active biomarker for small-molecule PSMA-targeted imaging and therapeutic agents for prostate cancer and various non-prostatic tumors that are characterized by PSMA expression on their neovasculature. One of the challenges for small-molecule PSMA inhibitors with respect to delivering therapeutic payloads is their rapid renal clearance. In order to overcome this pharmacokinetic challenge, we outfitted a (177)Lu-labeled phosphoramidate-based PSMA inhibitor (CTT1298) with an albumin-binding motif (CTT1403) and compared its in vivo performance with that of an analogous compound lacking the albumin-binding motif (CTT1401)...

The loss of the von Hippel-Lindau (VHL) tumor-suppressor is a major driver of Clear Cell Renal Cell Carcinoma (CC-RCC) resulting in the stabilization and overactivation of hypoxia inducible factors (HIFs). ROCK 1 is a well-known protein serine/threonine kinase which is recognized as having a role in cancer including alterations in cell motility, metastasis and angiogenesis. As a function of the later effect, we recently investigated and identified a synthetic lethal interaction between VHL loss and ROCK1 inhibition in CC-RCC that is dependent on HIF overactivation...

T-cell immunoglobulin and mucin domain (TIMD) family genes are related to innate immune responses. TIMD4 is a receptor for phosphatidylserine and is involved in the phagocytosis of apoptotic cells by macrophages. In the present study, we found that TIMD4 is expressed on the cancer cells of patients with clear cell renal cell carcinoma (ccRCC). TIMD4 was immunostained in the resected samples of 89 patients diagnosed as ccRCC. High expression of TIMD4 in cancer cells was closely related to short progression free survival time; however, it was not correlated with other clinicopathological factors...

Cancer stem cells (CSCs) are responsible for tumor initiation, progression, and resistance to therapeutic agents; they are usually less sensitive to conventional cancer therapies, and could cause tumor relapse. An ideal therapeutic strategy would therefore be to selectively target and destroy CSCs, thereby preventing tumor relapse. The aim of the present study was to evaluate the effectiveness of dendritic cells (DCs) pulsed with antigen derived from CD105+ human renal cell carcinoma(RCC) CSCs against renal cancer cells in vitro and in vivo...

The von Hippel-Lindau (VHL) tumor suppressor gene is often deleted or mutated in ccRCC (clear cell renal cell carcinoma) producing a non-functional protein. The gene encodes two mRNA, and three protein isoforms (pVHL213, pVHL160 and pVHL172). The pVHL protein is part of an E3 ligase complex involved in the ubiquitination and proteasomal degradation of different proteins, particularly hypoxia inducible factors (HIF) that drive the transcription of genes involved in the regulation of cell proliferation, angiogenesis or extracellular matrix remodelling...

Renal cell carcinoma (RCC) is a highly prevalent disease worldwide with many cases being metastasised to various organs during the time of initial presentation. Metastatic RCC to the breast is a rare entity and can mimic primary breast carcinoma. In this article, we present a 63-year-old Caucasian woman presented with a breast mass that was detected by screening mammography and found to have a biopsy proven grade-II clear RCC in the breast tissue. Despite the high incidence and prevalence of primary breast cancer, metastasis from extramammary should be suspected in patients with a prior history of other cancers...

Inversin, encoded by NPHP2, is one of the 10 NPHP proteins known to be involved in nephronophthisis (an autosomal recessive cystic kidney). Although the previous reports showed that inversin played an important role in embryonic development and renal diseases, its function in cancer was not revealed clearly so far. As measured by immunohistochemical staining, inversin was highly expressed in the cytoplasm of lung cancer samples (63.4%, 161/254) compared with adjacent normal lung tissues (22.0%, 11/50, p < 0...

AIMS: Heat shock proteins (HSPs) are a group of molecules induced by a variety of environmental and pathophysiologic stresses, including cancer. HSPs are implicated in the regulation of apoptosis and immunity in neoplasm. Transcription factor heat shock factor1 (HSF1) acts as the master regulator to control HSP expression, and therefore is involved in tumorigenesis. The purpose of this study was to evaluate the expression and clinicopathologic relevance of HSPs and HSF1 in clear cell renal cell carcinoma (ccRCC)...

Cancer cells can inhibit effector T cells (Teff) through both immunomodulatory receptors and the impact of cancer metabolism on the tumor microenvironment. Indeed, Teff require high rates of glucose metabolism, and consumption of essential nutrients or generation of waste products by tumor cells may impede essential T cell metabolic pathways. Clear cell renal cell carcinoma (ccRCC) is characterized by loss of the tumor suppressor von Hippel-Lindau (VHL) and altered cancer cell metabolism. Here, we assessed how ccRCC influences the metabolism and activation of primary patient ccRCC tumor infiltrating lymphocytes (TIL)...

Stauffer's syndrome is a rare paraneoplastic syndrome classically associated with renal cell carcinoma. It presents as abnormal hepatic panel in the absence of hepatic disease, which improves with treatment of the cancer and worsens with recurrence. Here, we describe a case of hepatic panel abnormalities in a patient with pancreatic cancer with no evidence of metastatic disease to the liver, primary hepatobiliary etiology, or clear offending medications. We believe this to be the first reported case of Stauffer's syndrome in patients with pancreatic cancer...

While the presence of multiple primary malignancies in the same patient is a well described phenomenon, there is no clear association between various histological subtypes of renal cell carcinoma (RCC) and the synchronous presence of colon malignancies. We present the rare case of an 81-year-old female patient suffering from chromophobe renal cell carcinoma (chRCC) and an angiomyolipoma of her left kidney, synchronous with an adenocarcinoma of the caecum. While there is an established connection between RCC and colon cancer, a literature review is performed to specify this association in regard to chRCC and the synchronous presence of colon malignancies...

Background: Clear cell renal cell carcinoma (CCRCC) is presumed to be associated with adipogenic differentiation. Histone modification is known to be important for adipogenesis, and the function of histone demethylase plant homeodomain finger 2 (PHF2) has been noted. In addition, PHF2 may act as a tumor suppressor via epigenetic regulation of p53 and is reported to be reduced in colon cancer and stomach cancer tissues. In this study, we examined PHF2 expression in CCRCC specimens by immunohistochemistry...

MicroRNA (miR)-125b has been identified as deregulated in a number of types of cancer. Previous studies have detected the expression of miR-125b in clear cell renal cell carcinoma (ccRCC) tissues by in situ hybridization and revealed that miR-125b was upregulated in ccRCC tissues, and was associated with recurrence and survival of patients with ccRCC. However, the function of miR-125b in RCC remains unclear. Thus, the expression of miR-125b was detected with quantitative polymerase chain reaction (qPCR) in 24 paired RCC and adjacent normal tissues...

The availability of tyrosine kinase inhibitors (TKI) during the past ten years has led to improved response and overall survival of patients suffering from metastatic clear cell renal cell carcinoma (ccRCC). However, most of these tumors will eventually progress due to resistance evolving under therapy. The objective of this pilot study was to determine whether molecular alterations in ccRCC tissues sampled over the course of the disease might be suggestive of potential therapies. We performed whole exome sequencing of nine samples from four patients in the MORE (Molecular Renal Cancer Evolution) trial...

Clear cell renal cell carcinoma (ccRCC) represents the most common type of kidney cancer with high mortality in its advanced stages. Our study aim was to explore the correlation between tumor epithelial-to-mesenchymal transition (EMT) and patient survival. Renal biopsies of tumorous and adjacent nontumorous tissue were taken with a 16 g needle from our patients (n = 26) undergoing partial or radical nephrectomy due to ccRCC RNA sequencing libraries were generated using Illumina TruSeq(®) Access library preparation protocol and TruSeq Small RNA library preparation kit...
