Caerts D, Garmyn M, Güvenç C. A Narrative Review of the Role of Estrogen (Receptors) in Melanoma. Int J Mol Sci 2024; 25:6251. [PMID: 38892441 PMCID: PMC11173079 DOI: 10.3390/ijms25116251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 05/27/2024] [Accepted: 06/03/2024] [Indexed: 06/21/2024] Open
Abstract
In this narrative review, we attempt to provide an overview of the evidence regarding the role of estrogen (receptors) in cutaneous melanoma (CM). We reviewed 68 studies and 4 systematic reviews and meta-analyses published from 2002 up to and including 2022. The prevailing presence of estrogen receptor β (ERβ) instead of estrogen receptor α (ERα) in CM is notable, with ERβ potentially playing a protective role and being less frequently detected in progressive cases. While men with CM generally experience a less favorable prognosis, this distinction may become negligible with advancing age. The role of oral contraceptives (OC) and hormone replacement therapy (HRT) in CM remains controversial. However, recent studies tend to associate the use of these exogenous hormones with a heightened risk of CM, mostly only when using estrogen therapy and not in combination with progesterone. On the contrary, the majority of studies find no substantial influence of in vitro fertilization (IVF) treatment on CM risk. Reproductive factors, including younger age at first childbirth, higher parity, and shorter reproductive life, show conflicting evidence, with some studies suggesting a lower CM risk. We suggest an important role for estrogens in CM. More research is needed, but the integration of estrogens and targeting the estrogen receptors in melanoma therapy holds promise for future developments in the field.

(4-Picolylamino)-17β-Estradiol derivative and analogues induce apoptosis with death receptor trail R2/DR5 in MCF-7. Chem Biol Interact 2023; 369:110286. [PMID: 36460128 DOI: 10.1016/j.cbi.2022.110286] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 11/07/2022] [Accepted: 11/24/2022] [Indexed: 11/30/2022]
Abstract
In order to discover more effective and less toxic drugs in the field of anti-tumor, the backbone structure of 17β-estradiol was modified, and 11 target compounds were synthesized. Compounds 5 and 10, which exhibited better anti-tumor activity and higher selectivity (more than 10-fold), were chosen for further biological investigation. Flow cytometry results indicated that 5 and 10 could arrest MCF-7 cells in the G2 phase and induce apoptosis. Immunohistochemical analysis revealed that 5 and 10 could bind to the estradiol receptor alpha in MCF-7 cells. Western blotting and real-time PCR assays were performed to detect the effects of compounds on apoptosis-related targets at the protein and gene levels. These results showed that both 5 and 10 could dosed-dependently increase the expression of Apaf-1, Bax, caspase-3,8,9 and reduce the expression levels of the anti-apoptotic factors Bcl-2 and Bcl-xL. Besides, the Human apoptosis array assay demonstrated the expression level of death receptor Trail R2/DR5 was upregulated obviously while the expression of TNF R1, IAPs and Hsp27/60/70 were downregulated. On the whole, 5 induced MCF-7 cell death through the endogenous pathway in mitochondria and the exogenous pathway with death receptor Trail R2/DR5.

Mutat Res 2021; 823:111763. [PMID: 34710701 DOI: 10.1016/j.mrfmmm.2021.111763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 09/24/2021] [Accepted: 10/17/2021] [Indexed: 11/20/2022]
Abstract
We previously reported that intronic single nucleotide variations (SNVs) in MITF (c.938-325G>A, rs7623610) and CREB1 (c.303+373G>A, rs10932201) genes were associated with risk, aggressiveness, and prognosis of cutaneous melanoma (CM). In this study, we investigated the influence of the above SNVs in splicing patterns and efficiency. We constructed minigenes with wild type and variant alleles from MITF and CREB1 to assess the effect of the SNVs on splicing. The minigenes were transfected in the human melanoma cell line (SK-MEL-28). RT-PCR and DNA sequencing investigated the constructs' splicing patterns. Minigenes constructs' splicing efficiency and HNRNPA1 and SF1 splicing genes' expression were investigated by qPCR. We found that MITF and CREB1 SNVs did not alter the splicing pattern, but they influenced the splicing efficiency. MITF-A (p= 0.03) and CREB1-A (p= 0.005) variant minigenes yielded an increase of mRNA generated from the constructions. Additionally, lower mRNA levels of HNRNPA1 and SF1 were seen in the variant minigenes MITF-A (p= 0.04) and CREB1-A (p= 0.005). We described for the first time the potential importance of MITF rs7623610 and CREB1 rs10932201 SNVs in splicing efficiency and its relationship with CM.

Abstract
MDM2 proto-oncogene, E3 ubiquitin protein ligase (MDM2) is a well-known oncogene and has been reported to be closely associated with epithelial-to-mesenchymal transition (EMT). The present study first demonstrated that the expression levels of MDM2 were markedly increased in TGF-β-induced EMT using quantitative PCR and western blotting. In addition, MDM2 was demonstrated to be associated with pathological grade in clinical glioma samples by immunohistochemical staining. Furthermore, overexpression of MDM2 promoted EMT in glioma, lung cancer and breast cancer cell lines using a scratch wound migration assay. Subsequently, the present study explored the mechanism by which MDM2 promoted EMT and revealed that MDM2 induced EMT by upregulating EMT-related transcription factors via activation of the B-Raf signaling pathway through tyrosine 3-monooxygenase activation protein ε using RNA sequencing and western blotting. This mechanism depended on the p53 gene. Furthermore, in vivo experiments and the colony formation experiment demonstrated that MDM2 could promote tumor progression and induce EMT via the B-Raf signaling pathway. Since EMT contributes to increased drug resistance in tumor cells, the present study also explored the relationship between MDM2 and drug sensitivity using an MTT assay, and identified that MDM2 promoted cell insensitivity to silibinin treatment in an EMT-dependent manner. This finding is crucial for the development of cancer therapies and can also provide novel research avenues for future biological and clinical studies.

Tantengco OAG, Richardson LS, Menon R. Effects of a gestational level of estradiol on cellular transition, migration, and inflammation in cervical epithelial and stromal cells. Am J Reprod Immunol 2020; 85:e13370.

Abstract
PROBLEM Estrogen (E2) is one of the main steroid hormones associated with pregnancy and parturition. High levels of E2 increase uterine contractions, promote fetal membrane weakening, and induce degradation of the cervical extracellular matrix (ECM). Current evidence supports the role of E2 in epithelial-to-mesenchymal transition (EMT) and inflammation in different cell types; however, its effects on the cellular components of the cervix are still unknown. METHOD OF STUDY In this study, we assessed the effects of gestational levels of E2 in: (a) the cellular transition of endocervical epithelial cells (EEC) and cervical stromal cells (CSC) in vitro using immunocytochemical staining and Western blot analyses for EMT markers (cytokeratin-18, E-cadherin, N-cadherin, SNAIL, and vimentin); (b) cell migration using in vitro scratch assays; (c) inflammatory cytokine (interleukin 1β and TNF-α) and MMP9 production under untreated and lipopolysaccharide (LPS)-treated conditions using immunoassays. RESULTS E2 treatment and co-treatment with LPS as a proxy for infection maintained the metastate of EEC (expression of both cytokeratin and vimentin) and the mesenchymal state of CSC. E2 delayed wound healing, which mimics the tissue remodeling process, in EEC and CSC. E2 led to persistently elevated levels of vimentin throughout the EEC wound healing process. E2 did not affect inflammatory cytokine production by EEC and CSC but increased MMP9 production by EEC. CONCLUSION Collectively, these results show that third trimester levels of E2 may permit localized inflammation, increase MMP-9 production, and cause an EMT-mediated impairment of the remodeling process in the cervix in vitro. These data suggest a potential contribution of E2 in cervical ripening.

Abstract
Background Drug repurposing is a swift, safe, and cheap drug discovery method. Melanoma disorders present low survival and high mortality rates and are challenging to diagnose and treat. Moreover, there is a high volume of worldwide investigations that are attempting to find melanoma-related genes of influence, which can be identified as responsive targets for reliable treatment. Method In this study, we used a wide range of data analyses to analyze over 1100 genes and proteins of influence with respect to cutaneous malignant melanoma. Our analysis included various investigational results from genome- and phenome-wide association studies (GWAS and PheWAS, respectively), biomedical, transcriptomic, and metabolomic datasets. We then researched the DrugBank for potential melanoma targets from the selected list. We excluded known melanoma targets to obtain a list of druggable proteins. We performed a precise analysis of the drugs’ pathogenesis and checked the expression profiles of the selected drugs having high associations with known anti-melanoma drugs. Result We found 35 drugs that interacted with 20 unique targets. These drugs appear to have high melanoma treatment potentials. We confirmed our results with previous studies and found supporting references for 30 of these drugs. In conclusion, this investigation can be applied to various diseases for the efficient and economical repurposing of various drug compounds. For further validation, the results may be applicable for in vivo tests and clinical trials.

In Vitro Effect of Estradiol and Progesterone on Ovine Amniotic Epithelial Cells. Stem Cells Int 2019; 2019:8034578. [PMID: 31049069 PMCID: PMC6458847 DOI: 10.1155/2019/8034578] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 01/30/2019] [Accepted: 02/05/2019] [Indexed: 01/26/2023] Open
Abstract
Amniotic epithelial cells (AECs), an emerging source of extrafoetal stem cells, have recently attracted attention for their great regenerative potential. Since AEC amplifications are accompanied by the loss of their native epithelial phenotype and by the progressive reduction of relevant biological properties, the issue to be addressed is the development of effective culture protocols. In this context, recently, it has been demonstrated that progesterone (P4) supplementation during ovine AEC (oAEC) expansion could prevent the undesirable epithelial-mesenchymal transition (EMT). In contrast, there is no information to date on the role of the other pregnancy steroids in culture. With this aim, the present study has been designed to clarify the impact of estradiol (E2), alone or in combination with P4 (12.5 μM and 25 μM), during oAEC amplification. Steroid supplementations were assessed by testing oAEC proliferation, stemness, EMT, and osteogenic or chondrogenic plasticity. The results indicated that EMT can be prevented exclusively in the presence of high doses of P4, while it occurred rapidly in cells exposed to E2 as denoted by protein (cytokeratin-8 and alpha-SMA) and gene expression (vimentin and snail) profiles. Moreover, steroid exposure was able to influence highly oAEC plasticity. Particularly, P4-treated cells displayed a precommitment towards osteogenic lineage, confirmed by the upregulation of OCN, RUNX2, and the greater deposition of calcium nodules. Conversely, P4 exposure inhibited oAEC chondrogenic differentiation, which was induced in E2-treated cells as confirmed by the upregulation of chondrogenesis-related genes (SOX9, ACAN, and COL2A1) and by the accumulation of Alcian blue-positive extracellular matrix. Simultaneously, E2-treated cells remained unresponsive to osteogenic inductive stimuli. In conclusion, media supplementation with high doses of steroids may be adopted to modulate phenotype and plasticity during oAEC amplification. Relevantly, the osteo or chondro steroid-induced precommitment may open unprecedented cell-based therapies to face the unsolved orthopaedic issues related to osteochondral regeneration.
