靶點詳情

  • 功能:
    Flavoprotein (FP) subunit of succinate dehydrogenase (SDH) that is involved in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q). Can act as a tumor suppressor.
  • 基因功能參考文獻:
    1. The six index cases described here presented with a variety of clinical manifestations extending the known phenotypic spectrum in SDHA disease. PMID: 28500238
    2. Report left ventricular non-compaction associated with Barth Syndrome due to triple mutations in TAZ, DTNA, and SDHA genes in multiple members of one family. PMID: 29508483
    3. We used a yeast model to characterize 22 SDHA VUS. These data revealed 16 (73%) of SDHA VUS as loss of function (and therefore pathogenic), highlighting the importance of understanding such variants to provide better clinical recommendations for genetic counselors concerning family screening and early detection protocols. PMID: 28724664
    4. Germline SDHA mutations are relatively common (7.6%) in patients with genetically unexplained paraganglioma (PGL). Most index patients presented with apparently sporadic PGL. In this SDHA series, the largest assembled so far, we found the lowest penetrance of all major PGL predisposition genes. PMID: 29177515
    5. We found that microRNA 31 (miR-31) suppressed succinate dehydrogenase complex subunit A (SDHA) expression, vital for mitochondrial electron transport chain (ETC) complex II PMID: 27346679
    6. This is only the second report supporting the dominant nature of the SDHA c.1351C>T (p.Arg451Cys) mutation being causative for an autosomal dominantly inherited mitochondrial metabolic disorder expanding the phenotypic presentation to an earlier onset of disease with additional cardiac involvement. PMID: 27683074
    7. The SDHA, TMEM127, MAX, and SDHAF2 genes contribute to hereditary pheochromocytoma and paraganglioma. PMID: 28384794
    8. SDH-deficient gastrointestinal stromal tumors (GISTs) account for approximately 8% of gastric GISTs and are associated with a high rate of distant metastasis, regardless of conventional risk category. PMID: 27340750

    12. After indirect co-culture, OP was increased in the BxPc-3 and Panc-1 cells; correspondingly, succinate dehydrogenase, FH and MCT expression were increased. After the MCT1-specific inhibitor removed 'tumor-stromal' metabolic coupling, the migration and invasion abilities of the pancreatic cancer cells were decreased. PMID: 28260082
    13. Data suggest that succinate dehydrogenases SDHA and SDHB immunohistochemistry should be interpreted with caution, due to possible false-positive or false-negative results, and ideally in the setting of quality assurance provided by molecular testing. PMID: 28179334
    14. Combined blockade of CDK and SDH, both genetically and pharmaceutically, showed synergy and resulted in inhibited proliferation, migration, invasion and migration in A2780 cells Cyclin E-driven OvCa cells appeared addicted to glucose metabolism via TCA. Combined CDKi with modalities targeting TCA, like SDHA inhibition showed promising effects for this genotype. PMID: 26826064
    15. According to international guidelines, SDHB, SDHC, and SDHD genetic testing were performed in this patient, but not SDHA, which would have been prescribed only after surgery, in case of SDHA negative immunohistochemistry PMID: 26490314
    16. As a similar defect of succinate dehydrogenase is apparent in patient cell-derived cardiomyocytes, the authors conclude that these defects represent a molecular basis for the cardiac pathology in Barth syndrome. PMID: 26697888
    17. our findings provide further evidence that patients with KIT/PDGFRA wild-type SDH-deficient GIST harboring SDHA mutations experience good survival outcomes PMID: 25188872
    18. This study strengthens the etiological association of SDH genes with pituitary neoplasia, renal tumorigenesis, and gastric gastrointestinal stromal tumors. Also, pancreatic neuroendocrine tumor falls within the SDH-related tumor spectrum. PMID: 26259135
    19. Three novel mutations in SDHA were found in patients presenting Leigh syndrome (LS) and/or leukodystrophy. PMID: 24781757

    21. SDH deficiency may promote tumorigenesis through accumulation of succinate and inhibition of dioxygenase enzymes. Inhibition of TET activity may, in turn, alter global DNA methylation and gene expression in SDH-deficient tumors. PMID: 23743927
    22. Data indicate that SDH5 is protected from mitochondrial LON protease (LONM)-mediated degradation in mitochondria by its stable interaction with SDHA, a state that is dysregulated in hereditary paraganglioma 2 (PGL2). PMID: 24414418
    23. Electron transport complex-II and manganese superoxide dismutase (MnSOD) enzyme activities were decreased in obese compared with non-obese pregnant women. PMID: 23956348

    27. Studies indicate that mutations in the mitochondrial complex II structural subunit genes SDHB, SDHC and SDHD and the regulatory subunit gene SDHAF2 in many paraganglioma families. PMID: 23291190
    28. Loss of SDHA expression in gastrointestinal stromal tumor (GIST) reliably predicts the presence of SDHA mutations, which represent a relatively common cause of SDH-deficient GIST in adults. PMID: 22955521
    29. Studies indicate that the pH change leads to the dissociation of SDHA and SDHB subunits from the remaining membrane-anchored subunits and the consequent block of enzymatic succinate-ubiquinone reductase (SQR) activity. PMID: 23000077
    30. Studies indicate that an array of tumor syndromes caused by complex II-associated mutations in genes SDHA, SDHB, SDHC, SDHD, SDHAF1 and SDHAF2 have been identified over a decade. PMID: 23174333
    31. Studies indicate that the flavinylation factor Sdh5 (SDHAF2) provided insight into the possible mechanism associated with Sdh1 (SDHA) flavinylation. PMID: 23380393
    32. A germline p.Arg31X nonsense SDHA mutation was identified in one of the six wild-type gastrointestinal stromal tumors cases. An additional SDHA missense mutation was identified in the extended KIT/PDGFRA WT GIST patients cohort. PMID: 22974104

    37. Tumor-derived FH and SDH mutations accumulate fumarate and succinate, leading to enzymatic inhibition of multiple alpha-KG-dependent dioxygenases and consequent alterations of genome-wide histone and DNA methylation. PMID: 22677546
    38. First report describing germline and somatic loss-of-function mutations in SDHA that are linked to the development of sporadic KIT/PDGFRA wild-type GISTs. PMID: 21505157
