ethylnitrosourea profile

Ethylnitrosourea (ENU) is a potent alkylating agent that induces mutations in DNA. It is synthesized by reacting ethylurea with nitrous acid. ENU is an effective mutagen in a variety of organisms, including mice, rats, and zebrafish. Its ability to induce mutations in a wide range of genes makes it a valuable tool for generating animal models of human diseases. ENU is also used in forward genetic screens to identify genes involved in various biological processes. Studies have shown that ENU can induce point mutations, deletions, and insertions in DNA. These mutations can lead to a variety of phenotypic effects, including cancer, developmental defects, and neurological disorders. ENU is widely used in research to study the effects of genetic mutations and to identify genes involved in disease pathogenesis. Its importance lies in its ability to induce mutations in a specific and predictable manner, making it a powerful tool for understanding the genetic basis of disease.'

Role	Description
alkylating agent	Highly reactive chemical that introduces alkyl radicals into biologically active molecules and thereby prevents their proper functioning. It could be used as an antineoplastic agent, but it might be very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. It could also be used as a component of poison gases.
mutagen	An agent that increases the frequency of mutations above the normal background level, usually by interacting directly with DNA and causing it damage, including base substitution.
carcinogenic agent	A role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.
genotoxin	A role played by a chemical compound to induce direct or indirect DNA damage. Such damage can potentially lead to the formation of a malignant tumour, but DNA damage does not lead inevitably to the creation of cancerous cells.

4 Hydroxyphenylpyruvate Dioxygenase Deficiency Disease [description not available]	2.41	2	0
Tyrosinemias A group of disorders which have in common elevations of tyrosine in the blood and urine secondary to an enzyme deficiency. Type I tyrosinemia features episodic weakness, self-mutilation, hepatic necrosis, renal tubular injury, and seizures and is caused by a deficiency of the enzyme fumarylacetoacetase. Type II tyrosinemia features INTELLECTUAL DISABILITY, painful corneal ulcers, and keratoses of the palms and plantar surfaces and is caused by a deficiency of the enzyme TYROSINE TRANSAMINASE. Type III tyrosinemia features INTELLECTUAL DISABILITY and is caused by a deficiency of the enzyme 4-HYDROXYPHENYLPYRUVATE DIOXYGENASE. (Menkes, Textbook of Child Neurology, 5th ed, pp42-3)	2.41	2	0

Neurofibromatosis 1 An autosomal dominant inherited disorder (with a high frequency of spontaneous mutations) that features developmental changes in the nervous system, muscles, bones, and skin, most notably in tissue derived from the embryonic NEURAL CREST. Multiple hyperpigmented skin lesions and subcutaneous tumors are the hallmark of this disease. Peripheral and central nervous system neoplasms occur frequently, especially OPTIC NERVE GLIOMA and NEUROFIBROSARCOMA. NF1 is caused by mutations which inactivate the NF1 gene (GENES, NEUROFIBROMATOSIS 1) on chromosome 17q. The incidence of learning disabilities is also elevated in this condition. (From Adams et al., Principles of Neurology, 6th ed, pp1014-18) There is overlap of clinical features with NOONAN SYNDROME in a syndrome called neurofibromatosis-Noonan syndrome. Both the PTPN11 and NF1 gene products are involved in the SIGNAL TRANSDUCTION pathway of Ras (RAS PROTEINS).	2.89	4	0
