ClassSmall Molecule
DescriptionAn organochlorine insecticide that has been used as a pediculicide and a scabicide. Lindane has been banned in California, United Kingdom, Australia, and many western countries due to concerns about neurotoxicity and adverse effects on the environment. In Canada, Lindane is not recommmended as a first-line therapy due to reports of resistance, neurotoxicity, and bone marrow suppression, but has been approved by the FDA as a second-line therapy for topical treatment of pediculosis capitis (head lice), pediculosis pubis (pubic lice), or scabies in patients greater than two years of age who cannot tolerate or have failed first-line treatment.

Toxicity Profile
Route of ExposureOral (5) ; inhalation (5) ; dermal (5) Lindane is absorbed significantly through the skin. A mean peak blood concentration of 28 nanograms per mL occurred in infants and children 6 hours after total body application of lindane lotion for scabies.
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. (5, 6, 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. (5). Other metabolites include 2-chlorophenol, 0-chlorophenol, chlorocyclohexane, chlorocyclohexanol. Half Life: 18 hours
Toxicity ValuesLindane is a moderately toxic compound via oral exposure, with a reported oral LD50 of 88 to 190 mg/kg in rats. It is moderately toxic via the dermal route as well, with reported dermal LD50 values of 500 to 1000 mg/kg in rats, 300 mg/kg in mice, 400 mg/kg in guinea pigs, and 300 mg/kg in rabbits. LD50: 76 mg/kg (Oral, Rat) (4) LD50: 50 mg/kg (Dermal, Rabbit) (4) LD50: 125 mg/kg (Intraperitoneal, Mouse) (4)
Lethal Dose28 g for an adult human. (9)
Carcinogenicity (IARC Classification)2B, possibly carcinogenic to humans. (8)
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. (5) Hexachlorocyclohexane is also used or the treatment of patients infested with Sarcoptes scabiei or pediculosis capitis who have either failed to respond to adequate doses, or are intolerant of other approved therapies.
Minimum Risk LevelAcute Oral: 0.003 mg/kg/day (7) Intermediate Oral: 0.00001 mg/kg/day (7)
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. (5, 6)
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. (6)
TreatmentHexachlorocyclohexane poisoning is treated symptomatically. Gastric lavage, followed by the administration of activated charcoal, may be performed upon ingestion. (10)

Targets

Target Details
1. Estrogen receptor
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.

Target Details
2. Estrogen receptor beta
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.

48. Transforming growth factor beta-1
General Function:
Type iii transforming growth factor beta receptor binding
Specific Function:
Multifunctional protein that controls proliferation, differentiation and other functions in many cell types. Many cells synthesize TGFB1 and have specific receptors for it. It positively and negatively regulates many other growth factors. It plays an important role in bone remodeling as it is a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation and differentiation in committed osteoblasts. Can promote either T-helper 17 cells (Th17) or regulatory T-cells (Treg) lineage differentiation in a concentration-dependent manner. At high concentrations, leads to FOXP3-mediated suppression of RORC and down-regulation of IL-17 expression, favoring Treg cell development. At low concentrations in concert with IL-6 and IL-21, leads to expression of the IL-17 and IL-23 receptors, favoring differentiation to Th17 cells.

Target Details
53. Vitamin D3 receptor
General Function:
Zinc ion binding
Specific Function:
Nuclear hormone receptor. Transcription factor that mediates the action of vitamin D3 by controlling the expression of hormone sensitive genes. Recruited to promoters via its interaction with BAZ1B/WSTF which mediates the interaction with acetylated histones, an essential step for VDR-promoter association. Plays a central role in calcium homeostasis.
Gene Name:
