Clear cell renal cell carcinoma (ccRCC) is the most common renal malignancy in adults, the incidence of which continues to increase. The lipid droplet protein perilipin 2 (PLIN2), which was originally considered an RNA transcript, is markedly expressed during adipocyte differentiation. In addition, it has been observed to be elevated in numerous types of cancer, including ccRCC; however, its essential function remains unclear in ccRCC. The present study examined the expression of PLIN2 in ccRCC, and aimed to determine the association between PLIN2 expression and patient survival...

Melanotic Xp11 translocation renal cancer is a rare category of MiTF/TFE3 neoplasms morphologically resembling Xp11 translocation renal cell carcinoma, Xp11 translocation perivascular epithelioid cell tumor, and melanoma. The diagnosis requires demonstration of TFE3 gene rearrangement, by either fluorescence in situ hybridization (FISH) at the Xp11.2 locus or by TFE3 immunohistochemistry. As cytology smears can be useful adjuncts in cytogenetic and molecular testing, we demonstrate TFE3 rearrangement by FISH analysis on cytologic smears in melanotic Xp11 translocation renal cancer...

Both Xp11 translocation renal cell carcinomas and the corresponding mesenchymal neoplasms are characterized by a variety of gene fusions involving TFE3. It has been known that tumors with different gene fusions may have different clinicopathologic features; however, further in-depth investigations of subtyping Xp11 translocation-associated cancers are needed in order to explore more meaningful clinicopathologic correlations. A total of 22 unusual cases of Xp11 translocation-associated cancers were selected for the current study; 20 cases were further analyzed by RNA sequencing to explore their TFE3 gene fusion partners...

PURPOSE OF REVIEW: Large-scale genomic profiling has shed new light on the molecular underpinnings of renal cell carcinoma (RCC), spurring a much needed refinement of RCC subclassification based on an integrative assessment of histopathologic features and molecular alterations. At the same time, renal mass biopsies have become increasingly commonplace, necessitating ancillary tools to help guide clinical management. Herein, we briefly review our current understanding of RCC genomics, highlighting areas of possible clinical utility, as well as potential limitations, for renal mass biopsies...

Aldolase A (fructose-bisphosphate aldolase A, ALDOA) is a glycolytic enzyme that catalyzes reversible conversion of fructose‑1,6-bisphosphate to glyceraldehyde 3-phosphate and dihydroxyacetone phosphate. ALDOA has been revealed to be related with many carcinomas, but its expression and function in renal cell carcinoma (RCC) remain unknown. This study aimed to detect expression of ALDOA in human RCC tissue samples and to explore its function in RCC cell lines. Reverse transcription-polymerase chain reaction was used to quantify ALDOA in human RCC samples...

Cutaneous and intraoral metastasis from any malignancy is not common. Cutaneous spread is usually noted in 5%-10% of high-grade malignancies, as in carcinoma breast, lung, colon, ovary, and malignant melanoma. Only 4.6% cases of cutaneous spread are from renal cell carcinoma (RCC). Intraoral spread from RCC is much rarer with an incidence of approximately 1% of all malignant oral tumors, noted sometimes in tongue, palate, buccal mucosa, gingiva, and lips. RCC is a highly aggressive tumor which requires early diagnosis for increasing the chance of cure...

Clear cell renal cell carcinoma (ccRCC) is the most common type of renal cell carcinoma, and anti-angiogenic treatment is currently first line therapy for metastatic ccRCC (mccRCC). Response rates and duration of response show considerable variation, and adverse events have a major influence on patient quality of life. The need for predictive biomarkers to select responders to receptor tyrosine kinase inhibitors upfront is urgent. We investigated the predictive value of immunohistochemical biomarkers associated with angiogenesis and systemic inflammation in mccRCC...

Immunohistochemistry is a basic routine in establishing the diagnosis of many tumors. However, immunomarkers are often irregularly distributed across different regions of the same tumor, alternating positive and negative areas without any apparent cause. Full identification of this type of intratumor heterogeneity is crucial for patients since the expression of many markers is linked to the prognosis and/or treatment of some tumors. We have quantified this variability testing 406 tumor samples from eight clear cell renal cell carcinomas using four epithelial-mesenchymal transition markers (vimentin, ZEB-1, β-catenin, and E-cadherin) and two different sampling protocols...

BACKGROUND: The mediator complex consists of 33 subunits and plays a central role in transcription. Studies have already described the involvement of individual subunits, especially in carcinogenesis. With regard to the subunit MED30, this has, so far, only been confirmed in gastric and breast carcinoma. The role of MED30 in urological tumours is unknown. MATERIALS AND METHODS: First, a database analysis using cBioPortal was performed for the mRNA expression and survival analysis of MED30 in clear cell renal cell carcinoma (ccRCC) and papillary RCC (pRCC)...

BACKGROUND: Improved diagnostic methods, including gene expression profiling, allow identification of the tissue of origin in most patients with carcinoma of unknown primary site (CUP). Patients with an occult renal cell carcinoma (RCC) are of particular interest, because effective treatment for advanced RCC has no overlap with the empiric chemotherapy used traditionally for CUP. We report the clinical characteristics, pathologic features, and response to RCC-specific treatment in CUP patients identified as RCC using a molecular cancer classifier assay (MCCA)...

BACKGROUND: The G protein-coupled bile acid receptor (TGR5) is a cell surface receptor which induces the production of intracellular cAMP and promotes epithelial-mesenchymal transition in gastric cancer cell lines. TGR5 is found in a wide variety of tissues including the kidney. However, the patterns of TGR5 expression have not been well characterized in physiologic kidney or renal neoplasms. We explore the expression of TGR5 in benign renal tissue and renal neoplasms and assess its utility as a diagnostic marker...
