KAT3B-p300 and H3AcK18/H3AcK14 levels are prognostic markers for kidney ccRCC tumor aggressiveness and target of KAT inhibitor CPTH2. Clin Epigenetics 2018; 10:44. [PMID: 29632619 PMCID: PMC5885315 DOI: 10.1186/s13148-018-0473-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2018] [Accepted: 03/14/2018] [Indexed: 12/26/2022] Open
Abstract
Background Kidney cancer and clear cell renal carcinoma (ccRCC) are the 16th most common cause of death worldwide. ccRCC is often metastasized at diagnosis, and surgery remains the main treatment; therefore, early diagnosis and new therapeutic strategies are highly desirable. KAT inhibitor CPTH2 lowers histone H3 acetylation and induces apoptosis in colon cancer and cultured cerebellar granule neurons. In this study, we have evaluated the effects of CPTH2 on ccRCC 786-O cell line and analyzed drug targets expressed in ccRCC tumor tissues at different grade. Results CPTH2 decreases cell viability, adhesion, and invasiveness in ccRCC cell line 786-O. It shows preferential inhibition for KAT3B-p300 with hypoacetilating effects on histone H3 at specific H3-K18. Immunohistochemical analysis of 70 ccRCC tumor tissues compared with peritumoral normal epithelium showed a statistical significant reduction of p300/H3AcK18 paralleled by an increase of H3AcK14 in G1 grade and an opposed trend during tumor progression to worst grades. In this study, we demonstrate that these marks are CPTH2 targets and significative prognosticators of low-grade ccRCC tumor. Conclusions ccRCC is substantially insensitive to current therapies, and the efficacy of clinical treatment is dependent on the dissemination stage of the tumor. The present study shows that CPTH2 is able to induce apoptosis and decrease the invasiveness of a ccRCC cell line through the inhibition of KAT3B. In a tumor tissue analysis, we identified new prognosticator marks in grade G1 ccRCC tumors. Low KAT3B/H3AcK18 vs. high H3AcK14 were found in G1 while an opposed trend characterized tumor progression to worst grades. Our collected results suggest that CPTH2 reducing KAT3B and H3AcK18 can be considered a promising candidate for counteracting the progression of ccRCC tumors.

Abstract
Cervical cancer (CC) is the second most common malignant cancer in women. CC is difficult to diagnose, has a high recurrence rate, and is resistant to systemic therapies; as a result, CC patients have a relatively poor prognosis. One potential link to CC is the Wnt signaling pathway and its downstream effectors, which regulate cell differentiation, proliferation, migration, and fate. The aberrant activation of Wnt signaling is associated with various cancers, including CC. Recent studies have shown that activating or inhibiting the intracellular signal transduction in this pathway can regulate cancer cell growth and viability. This review will summarize the experimental evidence supporting the significance of the Wnt signaling pathway in CC, and will also discuss the current clinical role of Wnt signaling in CC diagnosis, therapy, and prognosis.

Mol Med Rep 2017; 15:2511-2520. [PMID: 28447752 PMCID: PMC5428324 DOI: 10.3892/mmr.2017.6343] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2016] [Accepted: 02/09/2017] [Indexed: 12/18/2022] Open
Abstract
Previous studies from this group demonstrated that insulin gene enhancer binding protein ISL-1 (Islet-1) specifically induces the differentiation of mesenchymal stem cells (MSCs) into cardiomyocyte-like cells through histone acetylation. However, the underlying mechanisms remain unclear. In the present study, the role of the histone acetylation and DNA methylation on the regulatory mechanism of the Islet-1 was further investigated by methylation-specific polymerase chain reaction (PCR), chromatin immunoprecipitation quantitative PCR and western blot analysis. The results demonstrated that Islet-1 upregulated expression of general control of amino acid biosynthesis protein 5 (Gcn5) and enhanced the binding of Gcn5 to the promoters of GATA binding protein 4 (GATA4) and NK2 homeobox 5 (Nkx2.5). In addition, Islet-1 downregulated DNA methyltransferase (DNMT)-1 expression and reduced its binding to the GATA4 promoter. In contrast, the amount of DNMT-1 binding on Nkx2.5 did not match the expression trend. Therefore, it was concluded that Islet-1 may influence the histone acetylation and DNA methylation of GATA4 promoter region via Gcn5 and DNMT-1 during the MSC differentiation into cardiomyocyte-like cells, thus prompting the expression of GATA4. The Nkx2.5 was likely only affected by histone acetylation instead of DNA methylation. The present study demonstrated that Islet-1 induces the differentiation of mesenchymal stem cells into cardiomyocyte-like cells through a specific interaction between histone acetylation and DNA methylation on regulating GATA4.

Increased expression of SET domain-containing proteins and decreased expression of Rad51 in different classes of renal cell carcinoma. Biosci Rep 2016; 36:BSR20160122.

Abstract
Because of scant availability of tissue samples, we did not perform elaborate examination of chromatin immunoprecipitation and specific binding of SET domain-containing proteins to the promoters of Rad51. These remain avenues for future investigations. In the present study, we aimed to examine whether SET domain-containing methyltransferases are up-regulated in different classes of renal cell carcinoma. We immunoblotted against SET domain and quantified the expression of these modular domains. Furthermore, we examined the expression of Rad51, the key protein that confers genomic stability. There was enhanced expression of SET domain-containing histone methyltransferases in whole lysates of all classes of renal carcinoma. In metastatic high grade clear cell carcinoma, this expression was more pronounced. Though we could not demonstrate direct correlation, we showed that epigenetic modification by methylation is associated with decreased genomic translation of Rad51.

Detection of global hypermethylation in well-differentiated thyroid neoplasms by immunohistochemical (5-methylcytidine) analysis. J Endocrinol Invest 2015; 38:725-32. [PMID: 25740063 DOI: 10.1007/s40618-015-0246-2] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2014] [Accepted: 01/20/2015] [Indexed: 12/13/2022]
Abstract
PURPOSE While global hypomethylation of DNA has been found in several malignancies, studies on thyroid tumours have shown controversial results using different techniques. To help resolve this issue, we assessed methylation status using two different techniques in papillary thyroid carcinomas (PTC) and follicular adenomas (FA) and carcinomas (FTC), comparing adjacent non-neoplastic thyroid tissue. METHODS A series of 15 FA, 18 FTC and 17 PTC were assessed by: (1) measurement of methylation levels of long interspersed nuclear elements (LINE-1) using a combined bisulfite restriction analysis polymerase chain reaction protocol and (2) immunostaining with an anti-5-methylcytidine antibody that detects methylated DNA regardless of the DNA sequence. Immunostaining was scored by image analysis. RESULTS Methylation levels of LINE-1 in FA, FTC and PTC were not significantly different from adjacent normal tissue. There was no significant difference in methylation levels of LINE-1 between FA, FTC and PTC (p = 0.44). By immunohistochemical staining for methylation, the 5-methylcytidine score was significantly higher in tumours than in normal tissue counterparts, for FA (p < 0.001), FTC (p = 0.04) and PTC (p = 0.02). PTC showed the highest 5-methylcytidine expression amongst all tumours which was significantly different from FTC (p = 0.015), but not FA (p = 0.09). There was no correlation in methylation level between LINE-1 and 5-methylcytidine scores for each group and overall. CONCLUSIONS Well-differentiated thyroid neoplasms (FA, FTC and PTC) were not found by two independent methods to undergo global hypomethylation as part of an oncogenic sequence from normal tissue to carcinoma. Instead, hypermethylation was detected in all types of tumours, implying that this epigenetic event may contribute to oncogenic development of thyroid neoplasms (both benign and malignant).

Abstract
In 2012, an estimated 64,770 men and women were diagnosed with malignancy of the kidney and renal pelvis, of which 13,570 succumbed to their disease. Common genetic aberrations in renal cell carcinomas (RCCs) include loss of function of the VHL gene in clear-cell RCC, overexpression of the c-MET gene in papillary RCC type I, deficiency in the FH gene in papillary RCC type II and loss of heterozygozity of the BHD gene in chromophobe RCC. Recent studies illustrate epigenetic silencing of VHL, as well as alterations in histone modifications and their governing enzymes. The possibility of reversing these epigenetic marks has resulted in efforts to target these changes by utilizing inhibitors of HDACs, DNA methyltransferases and, recently, histone methyltransferases in preclinical and clinical studies. This article focuses on potential therapeutic interventions, and the implications of histone modifications and related enzyme alterations in RCC.

Abstract
CONTEXT The diagnosis of primary renal cell carcinomas (RCCs) with both papillary architecture and cells with clear cytoplasm can be diagnostically challenging for practicing pathologists. The 4 main neoplasms in the differential diagnosis are clear cell RCC, papillary RCC, clear cell papillary RCC, and Xp11 translocation RCC. Accurate diagnosis has both prognostic and therapeutic implications. OBJECTIVE To highlight the helpful cytomorphologic, immunohistochemical, and cytogenetic features of each of these entities to enable reproducible classification. DATA SOURCES Published peer-reviewed literature was reviewed, accompanied by the authors' personal experiences. CONCLUSIONS Key morphologic clues and a focused immunohistochemical panel, including CK7, α-methylacyl coenzyme A racemase (AMACR), TFE3, cathepsin K, and carbonic anhydrase IX (CAIX), now allow most resected RCCs with papillary architecture and clear cells to be accurately classified. In other cases, cytogenetic and molecular findings can establish the diagnosis. Despite these tools, some RCCs with papillary architecture and clear cells do not fit into any of the described entities and currently remain unclassified.
