We explored the role of the Krebs cycle enzyme fumarate hydratase (FH) in glucose-stimulated insulin secretion (GSIS). Mice lacking Fh1 in pancreatic β cells (Fh1βKO mice) appear normal for 6-8 weeks but then develop progressive glucose intolerance and diabetes. Glucose tolerance is rescued by expression of mitochondrial or cytosolic FH but not by deletion of Hif1α or Nrf2. Progressive hyperglycemia in Fh1βKO mice led to dysregulated metabolism in β cells, a decrease in glucose-induced ATP production, electrical activity, cytoplasmic [Ca2+]i elevation, and GSIS. Fh1 loss resulted in elevated intracellular fumarate, promoting succination of critical cysteines in GAPDH, GMPR, and PARK 7/DJ-1 and cytoplasmic acidification. Intracellular fumarate levels were increased in islets exposed to high glucose and in islets from human donors with type 2 diabetes (T2D). The impaired GSIS in islets from diabetic Fh1βKO mice was ameliorated after culture under normoglycemic conditions. These studies highlight the
Fumarate Hydratase: An enzyme that catalyzes the reversible hydration of fumaric acid to yield L-malic acid. It is one of the citric acid cycle enzymes. EC 4.2.1.2.
Fumarase is one of the key enzymes in the TCA cycle and has been implicated in virulence and survival of some microorganisms under suboptimal environmental conditions. In this study, the fumC genes that encode fumarase C (FUMCs) from Neisseria meningitidis, N. gonorrhoeae and N. subflava were identified by homology-based analysis, cloned by polymerase chain reactions and fully sequenced. The inferred primary sequence of neisserial FUMCs showed a high degree of conservation with 97.8-98.7% amino acid identity. However, phylogenetic analysis revealed that these neisserial FUMCs are divergent from class II fumarases found in other microorganisms, rat and human. The putative fumC genes were subcloned into the expression vector, pGEX-6P-1 and efficiently expressed in Esherichia coli BL21. The purified recombinant fusion proteins obtained by affinity chromatography demonstrated high catalytic activities (120-180 U/mg), thus authenticating the identities and functionalities of the cloned genes.

Reeds syndrome (or familial leiomyomatosis cutis et uteri) is a rare inherited condition characterised by multiple cutaneous leiomyomas and, in women, uterine leiomyomas. It predisposes for renal cell cancer, an association denominated hereditary leiomyomatosis and renal cell cancer, and it is also associated with increased risk of uterine leiomyosarcoma. The syndrome is caused by a mutation in the fumarate hydratase gene, which leads to an accumulation of fumarate. The inheritance pattern is autosomal dominant. Almost all women present with uterine fibroids, approximately 76% with dermal manifestations and 10-16% with renal tumors. The uterine fibroids tend to occur at younger age and larger and more numerous than in general population. They may be distinguishable from sporadic fibroids by special histological features such as prominent nucleoli with perinucleolar halos. The skin presentation is of asymmetrical, reddish-brown nodules or papules with a firm consistency, predominantly located on ...
The nucleotide sequences of two segments of DNA (2250 and 2921 base-pairs) containing the functionally related fumarase (fumC) and aspartase (aspA) genes of Escherichia coli K12 were determined. The fumC structural gene comprises 1398 base-pairs (466 codons, excluding the initiation codon), and it encodes a polypeptide of Mr 50353 that resembles the fumarases of Bacillus subtilis 168 (citG-gene product), rat liver and pig heart. The fumC gene starts 140 base-pairs downstream of the structurally-unrelated fumA gene, but there is no evidence that both genes form part of the same operon. The aspA structural gene comprises 1431 base-pairs (477 codons excluding the initiation codon), and it encodes a polypeptide of Mr 52190, similar to that predicted from maxicell studies and for the enzyme from E. coli W. Remarkable homologies were found between the primary structures of the fumarase (fumC and citG) and aspartase (aspA) genes and their products, suggesting close structural and evolutionary ...
HLRCC is one of several familial syndromes involving kidney cancer. The HLRCC Family Alliance is the worldwide support organization for Families with HLRCC.
Many women can treat occasional pelvic pain or discomfort with over-the-counter pain medication. Mutations in the fumarate hydratase gene cause hereditary leiomyomatosis and renal cell cancer in families in North America. If her partners penis hits the cervix during intercourse, it can cause the muscles to contract, which causes the cramping. The cause of fibroids is unknown, but Womens Health notes that a combination of hormonal imbalances and genetics is believed what fibroid is in uterus tumors be involved.

The preliminary outcome of the combination of immunotherapy and targeted therapy after recurrence and metastasis for hereditary leiomyomatosis and renal cell cancer-a case report
The Chinese had a somewhat different series of elements, namely Fire, Earth, Metal (literally gold), Water and Wood, which were understood as different types of energy in a state of constant interaction and flux with one another, rather than the Western notion of different kinds of material. Although it is usually translated as "element", the Chinese word xing literally means something like "changing states of being", "permutations" or "metamorphoses of being".[14] In fact Sinologists cannot agree on any single translation. The Chinese elements were seen as ever changing and moving - one translation of wu xing is simply "the five changes". The Wu Xing are chiefly an ancient mnemonic device for systems with five stages; hence the preferred translation of "movements", "phases" or "steps" over "elements." In the bagua, metal is associated with the divination figure 兌 Duì (☱, the lake or marsh: 澤/泽 zé) and with 乾 Qián (☰, the sky or heavens: 天 tiān). Wood is associated with 巽 ...

The effects of nicotinamide (NIC) and its natural plant metabolites nicotinic acid (NIA) and trigonelline (TRIG) were studied with respect to defense in plant cell cultures. NIC and NIA could protect against oxidative stress damage caused by 2,2′-azobis(2-amidinopropane) dihydrochloride (AAPH), which generates free radicals. Damage was analyzed as DNA strand breaks in cell cultures of Pisum sativum (garden pea), Daucus carota (carrot), Populus tremula L. × P. tremuloides (hybrid aspen) and Catharanthus roseus (Madagascar periwinkle), monitored by single cell gel electrophoresis (comet assay), and assays of cell leakage in C. roseus. The activities of aconitase and fumarase enzymes, which have key roles in energy metabolism, were analyzed in P. sativum cultures after treatment with NIC or NIA. Aconitase activity was increased by NIA, and fumarase activity was increased by both compounds. These compounds were shown to promote glutathione metabolism in P. sativum cultures, and NIC was shown to ...
Nuclear factor erythroid 2-related factor 2 (Nrf2) is involved in cell proliferation by promotion of metabolic activity. It is also the major regulator of antioxidants and has a pivotal role in tumor cell proliferation and resistance to chemotherapy. Accordingly, we investigated the role of Nrf2 in renal cell carcinoma (RCC). In 50 patients who had metastatic RCC and received cytoreductive nephrectomy, we performed Nrf2 gene mutation analysis using targeted next-generation sequencing, as well as investigating a specific single nucleotide polymorphism (SNP; rs6721961) in the Nrf2 promoter region and Nrf2 protein expression. Targeted next-generation sequencing revealed that five tumors had SNPs of Nrf2 associated with amino acid sequence variation, while 11 tumors had SNPs of Kelch-like ECH-associated protein 1 gene, 35 had SNPs of von Hippel-Lindau gene, and none had SNPs of fumarate hydratase gene. The three genotypes of rs6721961 showed the following frequencies: 60% for C/C, 34% for C/A, and 6% for A
Fumarase deficiency is extremely rare. Until a few years ago scientists knew of only thirteen cases worldwide. However, recently twenty additional cases have been documented in the border towns of Colorado City, Arizona, and Hildale, Utah. These two towns constitute a closed and controlled community, and were settled in the 1930s by the Fundamentalist Church of Jesus Christ of Latter Day Saints, which is a breakaway sect of The Church of Jesus Christ of Latter-day Saints. As such, many of the surrounding communities refer to this disease as "Polygamists Downs"[1] The fumarase deficiency gene has become very common in this community, due to the practice of inbreeding. It is believed that either Joseph Smith Jessop or one of the founders of the communities, or his wife carried the gene and passed it on to their descendants. The populations of Colorado City and Hildale are examples of the founder effect. ...

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) is an autosomal dominant tumor susceptibility syndrome, and the disease-related gene has been identified as fumarate hydratase (fumarase, FH). HLRCC-associated kidney cancer is an aggressive tumor characterized by early metastasis to regional lymph nodes and distant organs. Since early diagnosis and provision of definitive therapy is thought to be the best way to reduce the tumor burden, it is widely accepted that germline testing and active surveillance for an at-risk individual from a family with HLRCC is very important. However, it still remains controversial how we should treat HLRCC-associated kidney cancer. We successfully treated the patient with locally advanced HLRCC-associated kidney cancer, who has received active surveillance because of at-risk individual, by radical nephrectomy and extended retroperitoneal lymph node dissection, and examined surgically resected samples from a molecular point of view. We recommended that 13 at-risk
Alports syndrome is characterized clinically by a nonimmune glomerulopathy, often accompanied by sensorineural hearing loss and lens abnormalities, frequently due to mutations in the COL4A5 gene. The association of AS with diffuse leiomyomatosis, a benign proliferation of smooth muscle that occurs most often in the esophagus, trachea, and female genitalia, has been reported. Recently, a deletion involving both the COL4A5 and COL4A6 genes has been reported in four unrelated families. We report an additional case with Alports syndrome associated with leiomyomatosis carrying a deletion of both COL4A5 and COL4A6 genes. A detailed characterization of the genomic region involved in the deletion event has been performed. Our results demonstrate that the deletion removed exon 1 of COL4A5 and exons 1 and 2 of COL4A6.. ...

Cutaneous leiomyomas are divided into three subsets: (1) solitary or multiple piloleiomyomas originating from the arrector pili muscles; (2) genital leiomyomas originating from the mammillary, dartoic, or labial/vulvar muscles; and (3) angioleiomyomas, originating from vascular smooth muscle. Most leiomyomas are acquired; however, familial inheritance patterns have been described. Especially noteworthy are patients with multiple piloleiomyomas. Starting in early adulthood, these patients present with increasing numbers of tumors, developing as many as 100-1,000 lesions. Transmission appears to be autosomal dominant with variable penetrance.2 Women with multiple piloleiomyomas may also develop uterine leiomyomas, an entity termed multiple cutaneous and uterine leiomyomatosis (also known as familial leiomyomatosis cutis et uteri or Reed syndrome).2 In addition, some families with multiple cutaneous and uterine leiomyomatosis have been shown to cluster renal cell cancer, and this has been termed ...
The structure of Escherichia coli succinate dehydrogenase (SQR), analogous to the mitochondrial respiratory complex II, has been determined, revealing the electron transport pathway from the electron donor, succinate, to the terminal electron acceptor, ubiquinone. It was found that the SQR redox centers are arranged in a manner that aids the prevention of reactive oxygen species (ROS) formation at the flavin adenine dinucleotide. This is likely to be the main reason SQR is expressed during aerobic respiration rather than the related enzyme fumarate reductase, which produces high levels of ROS. Furthermore, symptoms of genetic disorders associated with mitochondrial SQR mutations may be a result of ROS formation resulting from impaired electron transport in the enzyme. |P /|
This gene encodes bifunctional mitochondrial protein that has both RNA-binding and hydratase activities. The encoded protein is a methylglutaconyl-CoA hydratase that catalyzes the hydration of 3-methylglutaconyl-CoA to 3-hydroxy-3-methyl-glutaryl-CoA, a critical step in the leucine degradation pathway. This protein also binds AU-rich elements (AREs) found in the 3 UTRs of rapidly decaying mRNAs including c-fos, c-myc and granulocyte/ macrophage colony stimulating factor. ARE elements are involved in directing RNA to rapid degradation and deadenylation. This protein is localizes to the mitochondrial matrix and the inner mitochondrial membrane and may be involved in mitochondrial protein synthesis. Mutations in this gene are the cause of 3-methylglutaconic aciduria, type I. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]
A uterine fibroid is a non-cancerous tumor that originates from the smooth muscle layer and the accompanying connective tissue of the uterus.
