Significance of intratissue estrogen concentration coupled with estrogen receptors levels in colorectal cancer prognosis. Oncotarget 2017; 8:115546-115560. [PMID: 29383180 PMCID: PMC5777792 DOI: 10.18632/oncotarget.23309] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2017] [Accepted: 12/05/2017] [Indexed: 12/17/2022] Open
Abstract
Dysregulation of estrogen related pathways is implicated colorectal cancer (CRC) development. However, significance of intratissue concentration of estrone (E1) and 17β-estradiol (E2) in relation to estrogen receptor (ESR) expression level was not addressed so far. Herein, we measured E1 and E2 intratissue concentration using liquid chromatography electrospray ionization tandem mass spectrometry (ESI LC/MS) and mRNA levels of ESR1 and ESR2 using RT-qPCR in cancerous and histopathologically unchanged tissue from 75 and 110 CRC patients, respectively. The obtained results were associated with clinicopathological factors, expression of estrogen dependent genes (CTNNB1, CCND1) and prognostic significance. We found no statistically significant differences in E1 or E2 concentration between cancerous tissue and histopathologically unchanged counterparts. Moreover, mRNA levels of ESR1 and ESR2 were significantly decreased in cancerous tissue compared with histopathologically unchanged (p=0.00001). Log rank analysis revealed no benefit of low E1 to E2 ratio, high E1, E2 concentration or ESR1, ESR2 mRNA level for patients’ overall (OS) and disease free survival (DFS). Interestingly, we have observed that patients with low ESR1 mRNA level coupled with low E1 intratissue concentration had a significant decrease in DFS compared with group of patients with high ESR1 mRNA level and high E1 concentration (HR=0.16, 95% CI 0.02-1.05; p=0.06). Furthermore, patients with low E1 concentration and low ESR1 transcript had significantly higher CTNNB1 and CCND1 mRNA level compare with subgroup with high level of both grouping factors. Our study indicates a potential value of estrogen intratissue concentration and its receptor expression level for CRC patients’ prognosis.

Abstract
Epidemiological and experimental findings suggest that the development of gastric cancer (GC) is regulated by steroid hormones. In postmenopausal women and older men, the majority of steroid hormones are produced locally in peripheral tissue through the enzymatic conversion of steroid precursors. Therefore, using reverse transcription-quantitative polymerase chain reaction analysis, the mRNA expression of genes encoding steroidogenic enzymes, including steroid sulfatase (STS), hydroxy-delta-5-steroid dehydrogenase 3 beta- and steroid delta-isomerase 1 (HSD3B1), 17β-hydroxysteroid dehydrogenase type 7 and aromatase (CYP19A1), was investigated in primary tumoral and adjacent healthy gastric mucosa from 60 patients with GC. Furthermore, the mRNA levels for estrogen receptor α, estrogen receptor β (ESR2) and androgen receptor (AR), along with their coregulators, including proline, glutamate and leucine rich protein 1, CREB binding protein, nuclear receptor coactivator 1 (NCOA1), nuclear receptor corepressor 1 (NCOR1) and nuclear receptor subfamily 2 group F member 1 (NR2F1), were investigated. Additionally, the association between the mRNA expression of these genes and the clinicopathological features of patients with GC was examined. Significantly decreased levels of STS, HSD3B1, ESR2, AR, NCOA1 and NCOR1 mRNA, in addition to significantly increased levels of CYP19A1 mRNA were demonstrated in tumoral tissue samples compared with adjacent healthy gastric tissue samples. Deregulated expression of these genes in the analyzed tissue samples was associated with certain clinicopathological features of GC, such as age and localization of the tumor. The results of the current study suggest that all of the genes analyzed are expressed in tumoral and adjacent healthy gastric mucosa. In addition, the results indicate that abnormal expression of STS, ESR2, AR, NCOA1 and NCOR1 may serve a role in the development and progression of GC, and may be associated with specific clinicopathological features in patients with GC.

Abstract
Colorectal cancer (CRC) is one of the most prevalent malignant tumors and the second cause of cancer-related mortality worldwide. Due to increased morbidity and mortality rates, there is an urgent need to understand the pathogenesis of CRC, discover strategies that can improve diagnosis, and ultimately identify therapies targeting this disease. Over the past several years, research into tumor progression mechanisms has been devoted to identifying and understanding various coding and non-coding regions of the genome and how these genetic variants may affect tumorigenesis and progression. Recently, long non-coding RNAs (lncRNAs), which are non‑protein coding transcripts longer than 200 nucleotides, have emerged as a key aspect in tumor pathogenesis. In the present study, we examined the lncRNA and mRNA expression profiles in 4 patients with colon adenocarcinoma, with paired adjacent normal tissues as controls. Microarray data showed that a total of 3,523 lncRNAs and 2,515 mRNAs were consistently differentially expressed in the CRC tissues compared to adjacent normal tissues. Upon comparison of the differentially expressed transcripts between the groups, we identified 22 pathways which were related to the upregulated transcripts and 24 pathways that corresponded to the downregulated transcripts. Gene ontology analysis revealed that the upregulated transcripts were predominantly enriched in DNA metabolic processes, and the downregulated transcripts were predominantly enriched in organic hydroxyl compound metabolic processes. Coding-non-coding gene co-expression analysis showed that these differentially expressed lncRNAs were closely correlated with 'Wnt signaling pathway' components, whose aberrant activation plays a central role in CRC, indicating that a functional correlation exists between them. In conclusion, the results of the microarray and informatic analysis strongly suggest that lncRNA dysregulation is involved in the complicated process of CRC development, and may represent a novel class of diagnostic markers or therapeutic targets for CRC.

Biomed Pharmacother 2015; 74:233-42.

Abstract
Epidemiological studies indicate that 17β-estradiol (E2) prevents colorectal cancer (CRC). Organic anion transporting polypeptides (OATPs) are involved in the cellular uptake of various endogenous and exogenous substrates, including hormone conjugates. Because transfer of estrone sulfate (E1-S) can contribute to intra-tissue conversion of estrone to the biologically active form -E2, it is evident that the expression patterns of OATPs may be relevant to the analysis of CRC incidence and therapy. We therefore evaluated DNA methylation and transcript levels of two members of the OATP family, OATP3A1 and OATP4A1, that may be involved in E1-S transport in colorectal cancer patients. We detected a significant reduction in OATP3A1 and a significant increase in OATP4A1 mRNA levels in cancerous tissue, compared with histopathologically unchanged tissue (n=103). Moreover, we observed DNA hypermethylation in the OATP3A1 promoter region in a small subset of CRC patients and in HCT116 and Caco-2 colorectal cancer cell lines. We also observed increased OATP3A1 transcript following treatment with 5-aza-2-deoxycytidine and sodium butyrate. The OATP4A1 promoter region was hypomethylated in analyzed tissues and CRC cell lines and was not affected by these treatments. Our results suggest a potential mechanism for OATP3A1 downregulation that involves DNA methylation during colorectal carcinogenesis.
