Abstract
BACKGROUND Mosaic loss of Y chromosome (LOY) is the most common chromosomal alteration in aging men. Here, we use single-cell RNA and ATAC sequencing to show that LOY is present in the kidney and increases with age and chronic kidney disease. RESULTS The likelihood of a cell having LOY varies depending on its location in the nephron. Cortical epithelial cell types have a greater proportion of LOY than medullary or glomerular cell types, which may reflect their proliferative history. Proximal tubule cells are the most abundant cell type in the cortex and are susceptible to hypoxic injury. A subset of these cells acquires a pro-inflammatory transcription and chromatin accessibility profile associated with expression of HAVCR1, VCAM1, and PROM1. These injured epithelial cells have the greatest proportion of LOY and their presence predicts future kidney function decline. Moreover, proximal tubule cells with LOY are more likely to harbor additional large chromosomal gains and express pro-survival pathways. Spatial transcriptomics localizes injured proximal tubule cells to a pro-fibrotic microenvironment where they adopt a secretory phenotype and likely communicate with infiltrating immune cells. CONCLUSIONS We hypothesize that LOY is an indicator of increased DNA damage and potential marker of cellular senescence that can be applied to single-cell datasets in other tissues.

Abstract
BACKGROUND Intra-operative cell salvage (IOCS) and leukocyte-depleted filter (LDF) are widely used and effective in saving blood. However, the safety issue concerning reinfusion of IOCS-LDF processed blood to renal cell carcinoma (RCC) patients with inferior vena cava (IVC) thrombus were inconclusive for fear of increased risk of cancer metastases. This study intends to analyze the circulating tumor cell (CTC) eliminating effect of IOCS-LDF in 5 RCC-IVC thrombus patients. METHODS A novel strategy integrating negative enrichment by immunomagnetic beads and immunostaining-fluorescence in situ hybridization with probes identifying aneuploid of 8 and/or 7 were used to detect CTCs from salvages blood. Blood samples were collected from 4 stages in each patient. RESULTS Of the 5 RCC patients, the number of CTCs decreased (from 3, 4, 10, 7, 3, respectively, to all zero) after IOCS-LDF treatment. The triploid of chromosome 7 and/or chromosome 8 were most common karyotype for RCC patients with IVC thrombus. Tetraploid of chromosome 8 occurred in only one sample and no polypoid (number of chromosome > 4) were found. CONCLUSION IOCS-LDF might be a promising way of reducing of allogeneic product transfusion based on current preliminary outcome. More convincing conclusions are to be drawn with enlarged sample size and long-term follow-up for patients prognosis.

Abstract
Clear cell renal cell carcinoma (ccRCC) and papillary renal cell carcinoma (pRCC) are the 2 most common RCCs. However, some RCCs can have both clear cell and papillary features, including clear cell papillary RCC (ccpRCC). They can be a diagnostic challenge in daily practice. Accurate diagnosis of these tumors is important for both patient prognosis and appropriate treatment. Fourteen RCCs with papillary architecture, clear cytoplasm and low Fuhrman grade were analyzed by SNP-based chromosome microarray (CMA). Seven cases had pathologic features of ccpRCC, and all had normal genomic profiles except one that had copy neutral loss of heterozygosity (cnLOH) of chromosome 3 and loss of one copy of the X chromosome. The remaining 7 cases also had papillae and clear cytoplasm. Two of these cases showed losses of chromosome 3 which are typically found in ccRCC. One had a gain of chromosome 7, which is commonly seen in pRCC. The remaining 4 had no alterations of chromosome 3 or 7. However, 3 of these 4 had monosomy 8, which are consistent with RCC with monosomy 8. The remaining case had no copy number alterations. This study shows that low-grade RCC with papillae and clear cell phenotype represents a heterogeneous group, including ccpRCC, ccRCC, pRCC, and RCC with monosomy 8. CMA analysis can be useful for the differential diagnosis of these neoplasms.

Abstract
AIMS The Cancer Genome Atlas (TCGA) provides an integrated resource for investigating the genetic, phenotypical and clinical characteristics of cancer. In this study, we aimed to define distinct subsets of clear cell renal cell carcinoma (ccRCC) through differential expression and principal component analyses. METHODS AND RESULTS We used DESeq2 to examine the expression profiles of 472 cases in TCGA. After a process of segregation and regrouping, we compared the mutation and copy number variation landscapes to discern two major clusters: cluster 1, composed mainly of classic ccRCC, and cluster 2, which was associated with gains at chromosomes 7 and 12. Gene set enrichment analysis disclosed that cluster 2 tumours were enriched in genes involving epithelial-mesenchymal transition. Histologically, cluster 2 tumours frequently exhibited cell elongation or spindling. Patients with cluster 2 tumours or tumours harbouring chromosomes 7 or 12 gains had a significantly greater cumulative incidence of mortality. We then employed fluorescence in-situ hybridisation with probes against chromosomes 7 and 12 in a cohort of 119 cases of ccRCC from our institute for validation. Chromosomes 7 and 12 gains were associated with lower survival rates in both univariate and multivariate analyses. CONCLUSIONS Our study demonstrates that genetic data obtained through appropriate molecular methodologies can be a useful adjunct to help predict prognosis. It also provides an example of exploring TCGA to extract meaningful information that can eventually contribute to precision medicine.

Clear cell renal carcinoma synchronous with dedifferentiated liposarcoma: a case report and review of the literature. J Med Case Rep 2020; 14:4.

Abstract
BACKGROUND Multiple primary malignant neoplasms are not frequent but are increasing in incidence. Some of them are associated with genetic syndromes such as von Hippel-Lindau syndrome and Li-Fraumeni syndrome. Dedifferentiated liposarcoma is one of the rarest soft tissue tumors, and clear cell renal carcinoma is the most frequent kidney cancer. The concomitant presence of these tumors is extremely rare; however, some cases have been reported, none of them presenting with liposarcoma of the limbs. We report an interesting case of a patient with synchronous multiple primary tumors presenting with a very rare liposarcoma associated with renal cell carcinoma (a very rare association). A review of the literature and a collection of similar cases published previously are also provided. CASE PRESENTATION We report a case of a 62-year-old Hispanic man who presented to our institution with a left thigh mass compatible with dedifferentiated liposarcoma synchronous with metastatic clear cell renal carcinoma. Multiple treatment lines were provided with no response, with a further metastatic transformation. Genetic analysis by liquid biopsy showed some mutations that were not susceptible to targeted therapy. At the time of this report, the patient is undergoing palliative care because his nonresponsive metastatic disease persists. CONCLUSIONS We present the first reported case of clear cell renal carcinoma synchronous with dedifferentiated liposarcoma of a limb. The association between renal cell carcinoma and dedifferentiated liposarcoma is unusual, and there are few reports of this presentation in the literature. More research about these tumors along with genetic tests needs to be performed to seek a better understanding of the fundamental basis of this rare association.

Tubulocystic renal cell carcinoma: a distinct clinicopathologic entity with a characteristic genomic profile. Mod Pathol 2019; 32:701-709. [PMID: 30622286 PMCID: PMC7549436 DOI: 10.1038/s41379-018-0185-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2018] [Revised: 11/06/2018] [Accepted: 11/07/2018] [Indexed: 11/09/2022]
Abstract
Tubulocystic renal cell carcinoma, a unique tumor, was recently included as a new entity in the World Health Organization classification of renal tumors. It has variably been reported to be related to other renal cell carcinomas, including papillary renal cell carcinoma, fumarate hydratase-deficient carcinoma, and others, likely because many such carcinomas may show variable amounts of tubulocystic architecture. The published data characterizing the molecular features of these tumors are inconsistent. We studied nine "pure" tubulocystic renal cell carcinomas, as defined by International Society of Urologic Pathologists (ISUP) and World Health Organization (WHO), by targeted next-generation sequencing, and fluorescence in situ hybridization for X and Y chromosomes, to investigate if these show any unique characteristics or any overlap with known mutational/molecular profiles or copy number alterations in other subtypes of renal cell carcinoma. All nine tubulocystic carcinomas demonstrated combined losses at chromosome 9 and gains at chromosome 17, as well as, loss of chromosome Y (in 5/5). None of the tumors showed mutational profiles characteristic of other renal neoplasms, including those seen in fumarate hydratase-deficient renal cell carcinoma. Recurrent mutations in chromatin-modifying genes, KMT2C and KDM5C, were detected in two of nine tumors. Thus, tubulocystic renal cell carcinoma, if defined strictly, at the clinical and pathologic level, demonstrates genomic features distinct from other subtypes of renal cell carcinoma. These findings support the contention that tubulocystic renal cell carcinoma should be diagnosed only using strict morphological criteria and only when presenting in a "pure" form; presence of variable papillary, poorly differentiated, or other architectural patterns most likely do not belong to the category of tubulocystic renal cell carcinoma.

Honokiol inhibits c-Met-HO-1 tumor-promoting pathway and its cross-talk with calcineurin inhibitor-mediated renal cancer growth. Sci Rep 2017; 7:5900.

Abstract
Honokiol (HNK) is a small molecule with potent anti-inflammatory and anti-tumorigenic properties; yet the molecular targets of HNK are not well studied. Hyperactivation of the receptor tyrosine kinase c-Met and overexpression of the cytoprotective enzyme heme oxygenase-1 (HO-1) play a critical role in the growth and progression of renal cell carcinoma (RCC). Interestingly, the calcineurin inhibitor (CNI) cyclosporine A (CsA), an immunosuppressant used to prevent allograft rejection, can also increase the risk of RCC in transplant patients. We studied the potential role of c-Met signaling axis on CNI-induced renal tumor growth and tested the anti-tumor efficacy of HNK. Importantly, CNI treatment promoted c-Met induction and enhanced c-Met-induced Ras activation. We found that HNK treatment effectively down-regulated both c-Met phosphorylation and Ras activation in renal cancer cells. It inhibited the expression of both c-Met- and CNI-induced HO-1, and promoted cancer cell apoptosis. In vivo, HNK markedly inhibited CNI-induced renal tumor growth; and it decreased the expression of phospho-c-Met and HO-1 and reduced blood vessel density in tumor tissues. Our results suggest a novel mechanism(s) by which HNK exerts its anti-tumor activity through the inhibition of c-Met-Ras-HO-1 axis; and it can have significant therapeutic potential to prevent post-transplantation cancer in immunosuppressed patients.

Abstract
In human tumors of distinct origin including renal cell carcinoma (RCC), the non-classical human leukocyte antigen G (HLA-G) is frequently expressed, thereby inhibiting the cytotoxic activity of T and natural killer (NK) cells. Recent studies demonstrated a strong post-transcriptional gene regulation of the HLA-G by miR-152, -148A, -148B and -133A. Standard methods were applied to characterize the expression and function of HLA-G, HLA-G-regulatory microRNAs (miRs) and the immune cell infiltration in 453 RCC lesions using a tissue microarray and five RCC cell lines linking these results to clinical parameters. Direct interactions with HLA-G regulatory miRs and the HLA-G 3' untranslated region (UTR) were detected and the affinities of these different miRs to the HLA-G 3'-UTR compared. qPCR analyses and immunohistochemical staining revealed an inverse expression of miR-148A and -133A with the HLA-G protein in situ and in vitro. Stable miR overexpression caused a downregulation of HLA-G protein enhancing the NK and LAK cell-mediated cytotoxicity in in vitro CD107a activation assays revealing a HLA-G-dependent cytotoxic activity of immune effector cells. A significant higher frequency of CD3+/CD8+ T cell lymphocytes, but no differences in the activation markers CD69, CD25 or in the presence of CD56+, FoxP3+ and CD4+ immune cells were detected in HLA-G+ compared to HLA-G- RCC lesions. This could be associated with higher WHO grade, but not with a disease-specific survival. These data suggest a miR-mediated control of HLA-G expression in RCC, which is associated with a distinct pattern of immune cell infiltration.

Abstract
The receptor tyrosine kinase c-Met is overexpressed in renal cancer cells and can play major role in the growth and survival of tumor. We investigated how the c-Met-mediated signaling through binding to its ligand hepatocyte growth factor (HGF) can modulate the apoptosis and immune escape mechanism(s) of renal cancer cells by the regulations of novel molecules heme oxygenase-1 (HO-1) and programmed death-1 ligand 1 (PD-L1). We found that HGF/c-Met-mediated signaling activated the Ras/Raf pathway and down-regulated cancer cell apoptosis; and it was associated with the overexpression of cytoprotective HO-1 and anti-apoptotic Bcl-2/Bcl-xL. c-Met-induced HO-1 overexpression was regulated at the transcriptional level. Next, we observed that c-Met induction markedly up-regulated the expression of the negative co-stimulatory molecule PD-L1, and this can be prevented following treatment of the cells with pharmacological inhibitors of c-Met. Interestingly, HGF/c-Met-mediated signaling could not induce PD-L1 at the optimum level when either Ras or HO-1 was knocked down. To study the functional significance of c-Met-induced PD-L1 expression, we performed a co-culture assay using mouse splenocytes (expressing PD-L1 receptor PD-1) and murine renal cancer cells (RENCA, expressing high PD-L1). We observed that the splenocyte-mediated apoptosis of cancer cells during co-culture was markedly increased in the presence of either c-Met inhibitor or PD-L1 neutralizing antibody. Finally, we found that both c-Met and PD-L1 are significantly up-regulated and co-localized in human renal cancer tissues. Together, our study suggests a novel mechanism(s) by which c-Met can promote increased survival of renal cancer cells through the regulation of HO-1 and PD-L1.

Abstract
A 67-year-old woman with a history of hypertension and type 2 diabetes mellitus was admitted to the hospital due to aphasia and left-sided hemiparesis during the past 5 h with resolution of symptoms within 24 h. On admission laboratory analysis showed haemoglobin 19.2 g/dL and haematocrit 55.1%. Cerebral CT scan was also performed on admission revealing periventricular leucoaraiosis. Studies to investigate the cause of erythrocytosis were started and elevated erythropoietin levels were found. In order to investigate a secondary cause of erythrocytosis an abdominal ultrasound was conducted revealing a left renal mass. CT scans of thorax, abdomen and pelvis confirmed renal mass 8 × 8 cm of diameter, suggestive of neoplasm without associated lymphadenopathy or metastases. Radical nephrectomy was performed and a pathological diagnosis demonstrated clear cell renal cell carcinoma and was staged as T2aN0M0.

Abstract
Clear cell renal cell carcinoma (ccRCC) is the most common type of renal cancer. The aim of this study was to define specific chromosomal imbalances in ccRCC that could be related to clinical or histologic prognostic factors. Tumors and karyotypes of 89 patients who underwent nephrectomy for ccRCC were analyzed from April 2009 to July 2012. The mean number of chromosomal aberrations was significantly higher (7.8; P < .05) in Fuhrman grade 4 (F4) than in F3 (4) and F2 (3.4) cases. The results were similar, considering separately the mean number of chromosomal losses and gains. The F4 cases had a distinct pattern with more frequent losses of chromosomes 9, 13, 14, 18, 21, 22, and Y and gains of chromosome 20. Necrosis was associated with losses of chromosomes 7, 9, 18, and 22; sarcomatoid component, losses of chromosomes 7, 9, and 14 and gains of 20; and T stage, losses of chromosomes 18 and Y. After multivariate analysis, renal fat invasion, renal vein emboli, and microscopic vascular invasion were, respectively, associated with losses of chromosomes 13 and Y, loss of chromosome 13, and loss of chromosome 14 and gains of chromosomes 7 and 20. F4 was independently associated with losses of chromosomes 9 and Y; sarcomatoid component, loss of chromosome 9 and gain of 20; necrosis, loss of chromosome 18; and T stage, loss of chromosome Y. These chromosomal imbalances can be detected routinely by karyotype or fluorescence in situ hybridization analyses to stratify patients for risk of progression.

Abstract
Despite recent advances in the understanding of the biology of renal cell carcinoma (RCC) and the implementation of novel targeted therapies, the overall 5 years' survival rate for RCC patients remains disappointing. Late presentation, tumor heterogeneity and in particular the lack of molecular biomarkers for early detection and classification represent major obstacles. Global, untargeted comparative analysis of RCC vs tumor adjacent renal epithelium (NN) samples by high throughput analyses both at the transcriptome and proteome level have identified signatures, which might further clarify the molecular differences of RCC subtypes and might allow the identification of suitable therapeutic targets and diagnostic/prognostic biomarkers, but none thereof has yet been implemented in routine clinical use. The increasing knowledge regarding the functional role of noncoding microRNA (miR) in physiological, developmental, and pathophysiological processes by shaping the protein expression profile might provide an important link to improve the definition of disease-relevant regulatory networks. Taking into account that miR profiling of RCC and NN provides robust signatures discriminating between malignant and normal tissues, the concept of evaluating and scoring miR/protein pairs might represent a strategy for the selection and prioritization of potential biomarkers and their translation into practical use.

Abstract
Background Deletions within the short arm of chromosome 7 are observed in approximately 25% of adult and 10% of Wilms pediatric renal tumors. Within Wilms tumors, the region of interest has been delineated to a 2-Mb minimal region that includes ten known genes. Two of these ten candidate genes, SOSTDC1 and MEOX2, are particularly relevant to tumor development and maintenance. This finding, coupled with evidence that SOSTDC1 is frequently downregulated in adult renal cancer and regulates both Wingless-Int (Wnt)- and bone morphogenetic protein (BMP)-induced signaling, points to a role for SOSTDC1 as a potential tumor suppressor. Methods To investigate this hypothesis, we interrogated the Oncomine database to examine the SOSTDC1 levels in adult renal clear cell tumors and pediatric Wilms tumors. We then performed single nucleotide polymorphism (SNP) and sequencing analyses of SOSTDC1 in 25 pediatric and 36 adult renal tumors. Immunohistochemical staining of patient samples was utilized to examine the impact of SOSTDC1 genetic aberrations on SOSTDC1 protein levels and signaling. Results Within the Oncomine database, we found that SOSTDC1 levels were reduced in adult renal clear cell tumors and pediatric Wilms tumors. Through SNP and sequencing analyses of 25 Wilms tumors, we identified four with loss of heterozygosity (LOH) at 7p and three that affected SOSTDC1. Of 36 adult renal cancers, we found five with LOH at 7p, two of which affected SOSTDC1. Immunohistochemical analysis of SOSTDC1 protein levels within these tumors did not reveal a relationship between these instances of SOSTDC1 LOH and SOSTDC1 protein levels. Moreover, we could not discern any impact of these genetic alterations on Wnt signaling as measured by altered beta-catenin levels or localization. Conclusions This study shows that genetic aberrations near SOSTDC1 are not uncommon in renal cancer, and occur in adult as well as pediatric renal tumors. These observations of SOSTDC1 LOH, however, did not correspond with changes in SOSTDC1 protein levels or signaling regulation. Although our conclusions are limited by sample size, we suggest that an alternative mechanism such as epigenetic silencing of SOSTDC1 may be a key contributor to the reduced SOSTDC1 mRNA and protein levels observed in renal cancer.

Abstract
Recently, renal angiomyoadenomatous tumor (RAT) has been identified. However, there are no descriptions about clear cell renal cell carcinoma (RCC) with focal RAT-like features. A 33-year-old Japanese man was found to have a tumor in the left kidney. Macroscopically, the tumor extended into the perinephric fat tissue, and the cut surface showed the yellowish color. The histologic examination of the tumor consisted of 2 components of clear cell RCC and RAT-like area. The RAT-like area showed the admixture of epithelial cells with basophilic or clear cytoplasm and stromal component containing leiomyomatous stroma, fine capillary network, and pericytic network. Immunohistochemically, epithelial neoplastic cells in RAT-like area were diffusely positive for CD10 and RCC Ma. G-band karyotype showed the structural abnormality of chromosome 3 and both components of clear cell RCC and RAT-like area revealed the identical VHL gene mutation. Finally, pathologists should pay attention to the presence of clear cell RCC focally resembling RAT.
