However, it is unclear at this time the role that MITF in particular plays in renal tumors. By studying a range of melanoma cell lines, the authors demonstrate a large variation in hypoxic response. The E318K mutation in the MITF gene has been associated with a high risk of melanoma, renal cell carcinoma, and pancreatic cancer; the risk of other cancers has not been evaluated so far. The main risk factors associated with melanoma are sun exposure and skin pigmentation, whereas kidney cancer risk is associated with common cancer-predisposing phenotypes such as obesity and smoking. In the current issue Sturm et al. Unlike other cancer predisposition syndromes, melanoma is not linked to a single gene, but several high- and intermediate-penetrance melanoma susceptibility genes have been identified to date ( Table 1 ).Penetrance relates to the lifetime risk for a mutation carrier of developing melanoma and reflects the overall contribution of a specific gene alteration to the risk of melanoma. Gene Lifetime Cancer and/or Tumor Risks* Newer Genes AIP Pituitary adenomas (benign pituitary tumors) ANKRD26 Thrombocytopenia, Acute myeloid leukemia (AML) among others, Myelodysplastic syndrome (MDS), Chronic myeloid leukemia (CML) AXIN2 Colorectal, Colon polyps BAP1 Renal, Melanoma-cutaneous and uveal, Mesothelioma, Basal cell carcinoma BARD1 Female breast However, melanoma and renal cell carcinoma (RCC) have been observed in the same patients and families often enough for a common underlying genetic factor to be suggested. Context: The microphthalmia-associated transcription factor (MITF) regulates the survival, proliferation, and differentiation of neural crest-derived lineages. We identified seven carriers (five patients with sporadic PCCs, two with PGLs). MITF recruits histone acetyltransferases p300 and CBP to activate gene transcription. CrossRef Medline Web of Science Google Scholar ↵ Fitzpatrick TB; Fitzpatrick TB. For example, when analyzing melanoma patient groups, the high risk group shows decreased STAT3, CEBPA and CEBPB, but increased MITF levels, indicating also higher proliferation for a certain time period. This means that an individual with this variant has a 50% chance of passing it on to their offspring. Pathogenic variants in newer genes, such as BAP1 and MITF, have been identified in families with renal cancer and may increase the risk for other cancers as well. Recent studies have shown that the same MITF mutation associated with increased risk of melanoma (E318K) also leads to increased risk of renal cell carcinoma (Bertolotto et al., 2011). The role of pigmentation in modulating human skin cancer risk continues to be incompletely understood. MITF belongs to a subfamily of bHLH-LZ transcription factor, called the MiT family, which also includes TFE3 and TFEB. In a French cancer-free and Italian control population, the frequency of carriers was 0.6% (14 of 2205). Herein, we examined the possible association of E318K and a novel variant of the MITF gene, V320I, with the risk of cancers of different sites of origin in a Polish population. MD Anderson Cancer Center, Houston, TX, USA 1Department of Medical Oncology, ... “MiTF/TFE translocation carcinomas family” [2]. La mutation E318K de MITF altèrerait la réponse au stress oxydant. Collectively, MITF might be the missing link between melanoma and kidney cancer and as the first common inherited factor between these two cancers (Bertolotto et al., 2011). 1988. Future studies will have to address the role of STAT3 and MITF in senescence programs of melanocytes, telomere stability, sex hormone, cytokine and growth factor action as well … However, a clear phenotypic characterization of nevi and tumor patterns in MITF E318K melanoma patients has been lacking so far. The frequency of adult TFE3 tRCC has been reported to range between 1 and 5% of all RCCs [3–5]. Our study objective, therefore, was to develop HuR-targeted therapy for melanoma. MITF family and renal cancer. Recent studies reported an increased risk of melanomain individuals carrying the rare variant MITF, p.E318K (rs149617956). “This MITF variant doubles the background risk for melanoma, which is approximately the same risk increase conferred by severe sunburns; however, an important aspect of this study is the elegant demonstration of how the E318K change affects MITF function,” says Tsao, who is an associate professor of dermatology at HMS. Cancer Cell 6: 565 – 576. Herein, we examined the possible association of E318K and a novel variant of the MITF gene, V320I, with the risk of cancers of different sites of origin in a Polish population. The p.K182R mutation introduced within the second MITF The pooled group of Mi-E318K carriers had a greater than fivefold risk SUMOylation site led to complete disappearance of the 120-kDa MITF of developing melanoma, RCC or both cancers, as compared to controls form, but had little effect on the 95-kDa doublet. MITF-M is the melanocyte-specific isoform of Microphthalmia-associated Transcription Factor (MITF) in human melanoma. Methods. Once such a variant is detected, it is possible to identify at-risk relatives who can pursue testing. We aim to evaluate the influence of this SNP on the risk and prognosis of CM, clinical and tumor characteristics, and MITF, SF1 and HNRNPA1 levels. tRCC usually occurs in children, adolescents and young adults, with a high female predominance [3–5]. The aim of this study was to test the prevalence of the MITF E318K mutation in 667 Italian melanoma patients. Yokoyama et al. MITF genotypes of 262 CM patients and 280 controls were identified in DNA by RT-PCR. These studies may show that the people who develop cancer are more or less likely to behave in certain ways or to be exposed to certain substances than those who do not develop cancer. Finally, we briefly discuss the role of MITF in kidney cancer, where it also plays a key role, and in immune cells, establishing MITF as a central mediator in the regulation of immune responses in melanoma and other cancers. associated with breast‑cancer risk have been identified through large‑scale genotyping studies. Most cancer risk (and protective) factors are initially identified in epidemiology studies. However, the role of this SNP in the risk and prognosis of CM patients is still unknown. Les rayonnements ultraviolets et l’hypoxie, qui sont impliqués dans le développement du mélanome et du cancer du rein respectivement, conduisent à la formation d’espèces réactives de l’oxygène (ROS). The prevalence of the MITF, p.E318K variant, was higher in the PCC/PGL cohort than in controls, and appears to be a significant risk factor (odds ratio, 3.19; 95% confidence interval, 1.34–7.59; P = .005). The evidence available to date may be derived from a small number of patients with wide confidence intervals or is based upon an ethnic cohort with one specific variant. Whether this variant plays a role in other neural crest-derived tumors is unknown. It may be that this mutation leads to disrupted interaction with TFE3. The E318K mutation in the MITF gene has been associated with a high risk of melanoma, renal cell carcinoma, and pancreatic cancer; the risk of other cancers has not been evaluated so far. ©2021, CANCER-RISKS - Mentions légales site Internet par TRIOTECH Chers amis de votre SANTE et de celle de tous les membres de votre FAMILLE, Ce portail "CANCER-RISKS" a pour objectif de vous aider à réduire les risques de cancers liés à des comportements contraires à votre santé. Somatic translocations involving TFE3, TFEB, and, in rare cases, MITF that result in fusion proteins have been shown to be driver alterations in sporadic RCC.17, 18, 19 While, a specific germline activating variant of MITF, p.E318K, has been shown to be a risk factor for the development of melanoma and RCC. Compared with the control group, MITF mRNA and protein levels were inhibited significantly to 42.9 ± 12.0% and 38.2 ± 9.8%, respectively, in miR-137 mimic-transfected MMQ cells. We observed significant associations between histological subtypes and family cancer history. These data indicate that the variant is very likely to be associated with disease. pancreatic cancer and kidney patients seemed to suffer from a significantly higher risk of developing melanoma (Ghiorzo et al., 2012). This work has implications for the understanding of intra-tumour heterogeneity in response to low oxygen and the efficacy of cancer treatments. MITF co-regulates a subset of hypoxia response genes with HIF and alters cellular metabolism to suppress pseudo-hypoxia. However, ... Critical role of CDK2 for melanoma growth linked to its melanocyte-specific transcriptional regulation by MITF. Similarly, the carriers of this variant were reported to have a 5 fold increased risk of developing melanoma, renal cell carcinoma or both these cancers (OR = 5.55 (95% CI 2.59-12.91, Bertolotto_2011). HuR is overexpressed in several human cancers, including melanoma, and is a molecular target for cancer therapy. In these studies, scientists look at large groups of people and compare those who develop cancer with those who don’t. (2011) independently identified the E318K mutation in the MITF gene (isoform MITF-M) as increasing the risk of melanoma in both families and sporadic cases. In approximately 5% of cancers, constitutional mutations that activate oncogenes or inactivate tumor suppressor genes (known as major genes or strong effect genes) confer a high risk (>50% lifetime risk) of developing cancer to the individuals who carry them, and are responsible for familial forms of cancer, cancers with an early age of onset, or multiple primary cancers. Hereditary predisposition to cancer due to the MITF E318K variant has autosomal dominant inheritance. Carriers with a personal and/or family history of pancreatic cancer and kidney cancer had a nearly 31‐ and eightfold higher risk of developing melanoma compared with wt patients. Carriers exhibited a nearly threefold higher risk of developing melanoma compared with controls. Some commercial genetic panels include a subset of these SNPs. The MC1R/cAMP/MITF pathway is a key determinant for growth, differentiation, and survival of melanocytes and melanoma. To determine if MITF was a direct target of miR-137, mRNA and protein expression of MITF were detected when miR-137 mimics were transfected into MMQ and GH3 cells. These variants typically have minor allele frequencies higher than 1%, and all confer risks that are less than 1.5 times as high as those in the general population; almost all these polymorphisms occur in noncoding sequences. Our findings further support MITF as a medium‐penetrance melanoma susceptibility gene, highlight a potential association with histological subtypes and suggest that MITF may predispose to pancreatic cancer.
