Abstract
BACKGROUND Clear cell renal cell carcinoma (ccRCC) is the most common subtype of renal cancer. The molecules (proteins, metabolites) secreted by tumors affect their extracellular milieu to support cancer progression. If secreted in amounts detectable in plasma, these molecules can also serve as useful, minimal invasive biomarkers. The knowledge of ccRCC tumor microenvironment is fragmentary. In particular, the links between ccRCC transcriptome and the composition of extracellular milieu are weakly understood. In this study, we hypothesized that ccRCC transcriptome is reprogrammed to support alterations in tumor microenvironment. Therefore, we comprehensively analyzed ccRCC extracellular proteomes and metabolomes as well as transcriptomes of ccRCC cells to find molecules contributing to renal tumor microenvironment. METHODS Proteomic and metabolomics analysis of conditioned media isolated from normal kidney cells as well as five ccRCC cell lines was performed using mass spectrometry, with the following ELISA validation. Transcriptomic analysis was done using microarray analysis and validated using real-time PCR. Independent transcriptomic and proteomic datasets of ccRCC tumors were used for the analysis of gene and protein expression as well as the level of the immune infiltration. RESULTS Renal cancer secretome contained 85 proteins detectable in human plasma, consistently altered in all five tested ccRCC cell lines. The top upregulated extracellular proteins included SPARC, STC2, SERPINE1, TGFBI, while downregulated included transferrin and DPP7. The most affected extracellular metabolites were increased 4-hydroxy-proline, succinic acid, cysteine, lactic acid and downregulated glutamine. These changes were associated with altered expression of genes encoding the secreted proteins (SPARC, SERPINE1, STC2, DPP7), membrane transporters (SLC16A4, SLC6A20, ABCA12), and genes involved in protein trafficking and secretion (KIF20A, ANXA3, MIA2, PCSK5, SLC9A3R1, SYTL3, and WNTA7). Analogous expression changes were found in ccRCC tumors. The expression of SPARC predicted the infiltration of ccRCC tumors with endothelial cells. Analysis of the expression of the 85 secretome genes in > 12,000 tumors revealed that SPARC is a PanCancer indicator of cancer-associated fibroblasts' infiltration. CONCLUSIONS Transcriptomic reprogramming of ccRCC supports the changes in an extracellular milieu which are associated with immune infiltration. The proteins identified in our study represent valuable cancer biomarkers detectable in plasma.

Abstract
Type 1 iodothyronine deiodinase (DIO1) regulates peripheral metabolism of thyroid hormones that control cellular proliferation, differentiation and metabolism. The significance of DIO1 in cancer is unknown. In this study we hypothesized that diminished expression of DIO1, observed in renal cancer, contributes to the carcinogenic process in the kidney. Here, we demonstrate that ectopic expression of DIO1 in renal cancer cells changes the expression of genes controlling cell cycle, including cyclin E1 and E2F5, and results in inhibition of proliferation. The expression of genes encoding collagens (COL1A1, COL4A2, COL5A1), integrins (ITGA4, ITGA5, ITGB3) and transforming growth factor-β-induced (TGFBI) is significantly altered in renal cancer cells with induced expression of DIO1. Finally, we show that overexpression of DIO1 inhibits migration of renal cancer cells. In conclusion, we demonstrate for the first time that loss of DIO1 contributes to renal carcinogenesis and that its induced expression protects cells against cancerous proliferation and migration.

Abstract
PURPOSE Renal cell carcinoma is the most common highly metastatic kidney malignancy. Adhesion has a crucial role in the metastatic process. TGF (transforming growth factor)-β1 is a pleiotropic cytokine that influences cancerous transformation. We hypothesized that 1) changes in the expression of adhesion related genes may influence survival rate of patients with renal cell carcinoma and 2) TGF-β1 may contribute to changed expression of adhesion related genes. MATERIALS AND METHODS Two-step quantitative real-time polymerase chain reaction arrays were used to analyze the expression of adhesion related genes in 77 tumors and matched pair controls. The prognostic significance of genes was evaluated in TCGA (The Cancer Genome Atlas) data on 468 patients with renal cell carcinoma. Quantitative real-time polymerase chain reaction and Western blot were applied for TGF-β1 analysis. TGF-β1 mediated regulation of gene expression was analyzed by TGF-β1 supplementation of Caki-2 cells and quantitative real-time polymerase chain reaction. RESULTS The expression of 19 genes related to adhesion and extracellular matrix remodeling was statistically significantly disturbed in renal cell carcinoma compared with controls. The 10-gene expression signature (COL1A1, COL5A1, COL11A1, FN1, ICAM1, ITGAL, ITGAM, ITGB2, THBS2 and TIMP1) correlated with poor survival (HR 2.85, p = 5.7e-10). TGF-β1 expression was 22 times higher in renal cell carcinoma than in controls (p <0.0001). TGF-β1 induced expression of TGFBI, COL1A1, COL5A1, COL8A1, FN1, ITGA5, ITGAM and TIMP1 in a renal cell carcinoma derived cell line. CONCLUSIONS Disturbed expression of genes involved in adhesion and extracellular matrix remodeling develops early during renal cell carcinoma carcinogenesis and correlates with poor survival. TGF-β1 contributes to changed expression of extracellular matrix and adhesion related genes. Bioinformatic analysis performed on a broad panel of cancers of nonkidney origin suggests that disturbed expression of genes related to extracellular matrix and adhesion may be a universal feature of cancerous progression.

Abstract
Thyroid hormone receptor beta (THRB) gene is commonly deregulated in cancers and, as strengthened by animal models, postulated to play a tumor-suppressive role. Our previous studies revealed downregulation of THRB in clear cell renal cell carcinoma (ccRCC), but the culpable mechanisms have not been fully elucidated. Since epigenetic regulation is a common mechanism influencing the expression of tumor suppressors, we hypothesized that downregulation of THRB in renal cancer results from epigenetic aberrances, including CpG methylation and microRNA-dependent silencing. Our study revealed that ccRCC tumors exhibited a 56% decrease in THRB and a 37% increase in DNA methyltransferase 1 (DNMT1) expression when compared with paired non-neoplastic control samples. However, THRB CpG methylation analysis performed using BSP, SNaPshot and MSP-PCR consistently revealed no changes in methylation patterns between matched tumor and control samples. In silico analysis resulted in identification of four microRNAs (miR-155, miR-425, miR-592, and miR-599) as potentially targeting THRB transcript. Luciferase assay showed direct binding of miR-155 and miR-425 to 3′UTR of THRB, and subsequent in vivo analyses revealed that transfection of UOK171 cell line with synthetic miR-155 or miR-425 resulted in decreased expression of endogenous TRHB by 22% and 64%, respectively. Finally, real-time PCR analysis showed significant upregulation of miR-155 (354%) and miR-425 (162%) in ccRCC when compared with matched controls. Moreover, microRNA levels were negatively correlated with the amount of THRB transcript in tissue samples. We conclude that CpG methylation is not the major mechanism contributing to decreased THRB expression in ccRCC. In contrast, THRB is targeted by microRNAs miR-155 and miR-425, whose increased expression may be responsible for downregulation of THRB in ccRCC tumors.

Abstract
microRNAs, short non-coding RNAs, influence key physiological processes, including hormonal regulation, by affecting the expression of genes. In this study we hypothesised that the expression of microRNAs targeting thyroid hormone pathway genes may be in turn regulated by thyroid hormone signalling. It is known that the expression of DIO1, a gene contributing to triiodothyronine (T3) signalling, is regulated by miR-224. Thus, we analysed mutual regulation between triiodothyronine pathway and miR-224/miR-452/GABRE cluster. Firstly, we found that miR-452 directly regulates the expression of thyroid hormone receptor TRβ1 in renal cancer cells. In turn, the expression of miR-224/452/GABRE cluster and other microRNAs targeting TRβ1 was influenced by T3 treatment and/or TR silencing. miR-452 expression correlated with intracellular T3 concentrations in renal tumours. In conclusion, we propose a new mechanism of feedback regulation, by which in renal cancer microRNAs regulate the expression of T3 pathway genes, while T3 in turn regulates expression of microRNAs.

Abstract
Background Clear cell renal cell carcinoma (ccRCC) is the most common type of renal cancer. One of the processes disturbed in this cancer type is alternative splicing, although phenomena underlying these disturbances remain unknown. Alternative splicing consists of selective removal of introns and joining of residual exons of the primary transcript, to produce mRNA molecules of different sequence. Splicing aberrations may lead to tumoral transformation due to synthesis of impaired splice variants with oncogenic potential. In this paper we hypothesized that disturbed alternative splicing in ccRCC may result from improper expression of splicing factors, mediators of splicing reactions. Methodology/Principal Findings Using real-time PCR and Western-blot analysis we analyzed expression of seven splicing factors belonging to SR proteins family (SF2/ASF, SC35, SRp20, SRp75, SRp40, SRp55 and 9G8), and one non-SR factor, hnRNP A1 (heterogeneous nuclear ribonucleoprotein A1) in 38 pairs of tumor-control ccRCC samples. Moreover, we analyzed splicing patterns of five genes involved in carcinogenesis and partially regulated by analyzed splicing factors: RON, CEACAM1, Rac1, Caspase-9, and GLI1. Conclusions/Significance We found that the mRNA expression of splicing factors was disturbed in tumors when compared to paired controls, similarly as levels of SF2/ASF and hnRNP A1 proteins. The correlation coefficients between expression levels of specific splicing factors were increased in tumor samples. Moreover, alternative splicing of five analyzed genes was also disturbed in ccRCC samples and splicing pattern of two of them, Caspase-9 and CEACAM1 correlated with expression of SF2/ASF in tumors. We conclude that disturbed expression of splicing factors in ccRCC may possibly lead to impaired alternative splicing of genes regulating tumor growth and this way contribute to the process of carcinogenesis.

Abstract
Background Triiodothyronine regulates proliferation acting as stimulator or inhibitor. E2F4 and E2F5 in complexes with pocket proteins p107 or p130 stop cells in G1, repressing transcription of genes important for cell cycle progression. p107 and p130 inhibits activity of cyclin/cdk2 complexes. Expression of all those proteins could be regulated by triiodothyronine. In clear cell renal cell carcinoma many disturbances in T3 signaling pathway was described, in that type of cancer also expression of some key G1 to S phase progression regulators was shown. Methods We investigated role of T3 and its receptors in regulation of proliferation of HK2, Caki-2, Caki-1 cell lines (cell counting, cytometric analysis of DNA content) and expression of thyroid hormone receptors, E2F4, E2F5, p107 and p130 (western blot and semi-quantitative real time PCR). Statistical analysis was performed using one-way ANOVA. Results and Conclusion We show that T3 inhibits proliferation of HK2, and stimulates it in Caki lines. Those differences are result of disturbed expression of TR causing improper regulation of E2F4, E2F5, p107 and p130 in cancer cells.

Abstract
The expression of cyclin E gene (CCNE) in relation to the expression of its major regulatory protein, E2F1, was examined in clear cell renal cell carcinomas (ccRCC). We show that the overexpression of E2F1 is accompanied by the significant increase of the mean amounts of cyclin E mRNA, as well as of total cyclin E protein and its low molecular weight forms in cancer tissues as compared to peritumoral controls. A significant increase of the mean amount of total cyclin E was found in peritumoral tissues compared to cancer-free kidneys, suggesting that cancer cells might secrete factors having a profound influence on the metabolism of neighbouring tissues. A significant, positive correlations between E2F1 protein and total cyclin E mRNA, as well as between E2F1 protein and full length cyclin E protein were found in cancer-free kidneys and in peritumoral tissues, but not in ccRCCs. The overexpression of cyclin E positively correlated with the decreasing degree of tumor differentiation, implicating a role for cyclin E in the promotion of tumorigenesis.

Abstract
The expression of cyclin E gene (CCNE) in relation to the expression of its major regulatory protein, E2F1, was examined in clear cell renal cell carcinomas (ccRCC). We show that the overexpression of E2F1 is accompanied by the significant increase of the mean amounts of cyclin E mRNA, as well as of total cyclin E protein and its low molecular weight forms in cancer tissues as compared to peritumoral controls. A significant increase of the mean amount of total cyclin E was found in peritumoral tissues compared to cancer-free kidneys, suggesting that cancer cells might secrete factors having a profound influence on the metabolism of neighbouring tissues. A significant, positive correlations between E2F1 protein and total cyclin E mRNA, as well as between E2F1 protein and full length cyclin E protein were found in cancer-free kidneys and in peritumoral tissues, but not in ccRCCs. The overexpression of cyclin E positively correlated with the decreasing degree of tumor differentiation, implicating a role for cyclin E in the promotion of tumorigenesis.

Abstract
The effect of melatonin on glucose metabolism in the presence and absence of insulin has been investigated in the primary cultures of renal tubules grown in a defined medium. In the absence of glucose in the medium containing 5 microg/mL of insulin and 2 mm alanine + 5 mm glycerol + 0.5 mm octanoate, 100 nm melatonin stimulated both glucose and lactate synthesis, while in the medium devoid of insulin melatonin action was negligible. Melatonin-induced increase in glucose and lactate synthesis was accompanied by an enhancement of alanine and glycerol consumption. In view of measurements of [U-14C]L-alanine and [U-14C]L-glycerol incorporation into glucose, it is likely that melatonin increased alanine utilization for glucose production, while accelerated lactate synthesis was because of an enhanced glycerol consumption. As (i) 10 nm luzindole attenuated the stimulatory action of melatonin on glucose formation and (ii) the indole induced a decrease in intracellular cAMP level, it seems likely that in renal tubules melatonin binds to ML1 membrane receptor subtype. In view of a decline of intracellular fructose-1,6-bisphosphate content accompanied by a significant rise in hexose-6-phosphate and glucose levels, melatonin might result in an acceleration of flux through fructose-1,6-bisphosphatase probably because of an increase in the active, dephosphorylated form of this enzyme. Thus, the administration of melatonin in combination with insulin might be beneficial for diabetic therapy because of protection against hypoglycemia.

Abstract
AIMS The effect of ethanol on glucose synthesis in kidney-cortex tubules of control and diabetic rabbits has been investigated. METHODS Both freshly isolated and grown in primary cultures, kidney-cortex tubules were incubated with alanine or aspartate plus lactate or glycerol plus octanoate in the absence and presence of 100 mmol/l ethanol. RESULTS In freshly isolated renal tubules incubated in the presence of alanine plus lactate or glycerol plus octanoate, and in tubules grown in primary culture in the medium containing alanine plus lactate plus octanoate alcohol, resulted in about 30% decrease in glucose formation. A diminished glucose production in freshly isolated tubules was accompanied by: (i) a decrease in alanine utilization, (ii) an increase in lactate or glycerol consumptions and (iii) a decline in GSH:GSSG ratio. The ethanol action was not abolished by 4-methylpyrazole, an inhibitor of alcohol dehydrogenase (ADH). In view of ethanol-induced changes in gluconeogenic intermediates it is likely that in the presence of alanine plus glycerol plus octanoate ethanol causes a decline in flux through phosphoenolpyruvate carboxykinase, probably due to either an increase in intracellular content of 2-oxoglutarate, inhibitor of this key gluconeogenic enzyme and/or an enhanced flux through pyruvate kinase, as concluded from an increased lactate formation in the presence of glycerol in the incubation medium. In renal tubules grown in primary cultures in the presence of alanine plus lactate plus octanoate a decrease in GSH:GSSG ratio was accompanied by elevated generation of reactive oxygen species (ROS). Upon replacement of alanine by aspartate ethanol affected neither glucose production, substrate uptake, ROS accumulation nor GSH:GSSG ratio. CONCLUSIONS In the presence of alanine ethanol-induced decrease in glucose production and elevation of ROS might cause a limited NADPH generation resulting in a decrease in the intracellular GSH:GSSG ratio. On the contrary, aspartate might protect against ROS generation, so intensive gluconeogenesis supports NADPH generation and in consequence high values of the intracellular GSH:GSSG ratio are maintained.
