ClassSmall Molecule
DescriptionBeta Hexachlorocyclohexane(beta-HCH) is one of eight isoforms of the commercially manufactured chemical hexachlorocyclohexane. It is used as an insecticide on fruit, vegetables, and forest crops and is also available as a prescription (lotion, cream, or shampoo) to treat head and body lice, and scabies. (3). beta-HCH causes nonestrogenic immune function changes in the adult mouse without gross changes in lymphoid organ weight, histology, or cellularity.

Toxicity Profile
Route of ExposureOral (3) ; inhalation (3) ; dermal (3)
Mechanism of ToxicityHexachlorocyclohexane is a neurotoxin that interferes with GABA neurotransmitter function by interacting with the GABA-A receptor-chloride channel complex at the picrotoxin binding site, causing over stimulation of the central nervous system. It is also believed to inhibit sodium/potassium-transporting ATPases and be an endocrine disruptor. In the liver, hexachlorocyclohexane is thought to cause oxidative stress by interfering with hepatic oxidative capacity and glutathione metabolism, increasing lipid metabolism, and inhibiting magnesium ATPase activity. Hexachlorocyclohexane may also inhibit gap junction and intercellular communication, leading to uncontrolled cell growth and tumor promotion. (3, 4, 1)
MetabolismHexachlorocyclohexane is absorbed through the skin, lungs, and intestines, then distributed mainly to the adipose tissue but also to the brain, kidney, muscle, and blood. Metabolism occurs via dechlorination, dehydrogenation, dehydrochlorination, and hydroxylation by hepatic cytochrome P-450 enzymes. The main metabolites are polychlorophenols and 1,2,4-trichlorocyclohexane-4,5-epoxide, which are excreted in the urine. (3)
Toxicity ValuesLD50: 6 g/kg (Oral, Rat) (2)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)2B, possibly carcinogenic to humans. (6)
Uses/SourcesHexachlorocyclohexane is used as an insecticide on fruit, vegetables, and forest crops and is also available as a prescription (lotion, cream, or shampoo) to treat head and body lice, and scabies. (3)
Minimum Risk LevelAcute Oral: 0.05 mg/kg/day (5) Intermediate Oral: 0.0006 mg/kg/day (5)
Health EffectsExposure to large amounts of hexachlorocyclohexane can harm the nervous system, producing a range of symptoms from headache and dizziness to seizures, convulsions and more rarely death. Hexachlorocyclohexane is known to damage the liver, kidneys, and immune system, as well as cause blood disorders and reproductive and developmental defects. Hexachlorocyclohexane is also potentially carcinogenic. (3, 4)
SymptomsExposure to large amounts of hexachlorocyclohexane can harm the nervous system, producing a range of symptoms from headache and dizziness to seizures, convulsions and more rarely death. (4)
TreatmentHexachlorocyclohexane poisoning is treated symptomatically. Gastric lavage, followed by the administration of activated charcoal, may be performed upon ingestion. (7)

General Function:
Zinc ion binding
Specific Function:
Nuclear receptor that binds and is activated by variety of endogenous and xenobiotic compounds. Transcription factor that activates the transcription of multiple genes involved in the metabolism and secretion of potentially harmful xenobiotics, drugs and endogenous compounds. Activated by the antibiotic rifampicin and various plant metabolites, such as hyperforin, guggulipid, colupulone, and isoflavones. Response to specific ligands is species-specific. Activated by naturally occurring steroids, such as pregnenolone and progesterone. Binds to a response element in the promoters of the CYP3A4 and ABCB1/MDR1 genes.

General Function:
Zinc ion binding
Specific Function:
Nuclear hormone receptor. The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Ligand-dependent nuclear transactivation involves either direct homodimer binding to a palindromic estrogen response element (ERE) sequence or association with other DNA-binding transcription factors, such as AP-1/c-Jun, c-Fos, ATF-2, Sp1 and Sp3, to mediate ERE-independent signaling. Ligand binding induces a conformational change allowing subsequent or combinatorial association with multiprotein coactivator complexes through LXXLL motifs of their respective components. Mutual transrepression occurs between the estrogen receptor (ER) and NF-kappa-B in a cell-type specific manner. Decreases NF-kappa-B DNA-binding activity and inhibits NF-kappa-B-mediated transcription from the IL6 promoter and displace RELA/p65 and associated coregulators from the promoter. Recruited to the NF-kappa-B response element of the CCL2 and IL8 promoters and can displace CREBBP. Present with NF-kappa-B components RELA/p65 and NFKB1/p50 on ERE sequences. Can also act synergistically with NF-kappa-B to activate transcription involving respective recruitment adjacent response elements; the function involves CREBBP. Can activate the transcriptional activity of TFF1. Also mediates membrane-initiated estrogen signaling involving various kinase cascades. Isoform 3 is involved in activation of NOS3 and endothelial nitric oxide production. Isoforms lacking one or several functional domains are thought to modulate transcriptional activity by competitive ligand or DNA binding and/or heterodimerization with the full length receptor. Essential for MTA1-mediated transcriptional regulation of BRCA1 and BCAS3. Isoform 3 can bind to ERE and inhibit isoform 1.

General Function:
Zinc ion binding
Specific Function:
Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner (PubMed:20074560). Isoform beta-cx lacks ligand binding ability and has no or only very low ere binding activity resulting in the loss of ligand-dependent transactivation ability. DNA-binding by ESR1 and ESR2 is rapidly lost at 37 degrees Celsius in the absence of ligand while in the presence of 17 beta-estradiol and 4-hydroxy-tamoxifen loss in DNA-binding at elevated temperature is more gradual.
