Persistent β-Hexachlorocyclohexane Exposure Impacts Cellular Metabolism with a Specific Signature in Normal Human Melanocytes

Cells
Background: Cutaneous melanoma arises from skin melanocytes and has a high risk of metastatic spread. Despite better prevention, earlier detection, and the development of innovative therapies, melanoma incidence and mortality increase annually.

Hexachlorocyclohexane-Induced Tumorigenicity in Mice under Different Experimental Conditions

, 1983
Continuous administration of 500 ppm hexachlorocyclohexane (HCH) in the diet induced 100 % liver tumors in mice, but none were observed in rats and hamsters treated with the same dose of HCH.

In vitro effects of the organochlorine pesticide β-hexachlorocyclohexane on bovine peripheral blood mononuclear cells

Italian Journal of Animal Science, 2014
The β-hexachlorocyclohexane (β-HCH) is a very stable and accumulable isomer of Lindane, a well known organochlorine pesticide. The HCHs were banned in all developed countries but to date high concern still exists for environment, animal and human health ...

Insecticides. Part V. Crystal structures of β-(eeeeee)-1,2,3,4,5,6- hexachlorocyclohexane and γ-(aaaeee)-1,2,3,4,5,6-hexachlorocyclohexane (lindane) (redeterminations)

, 1976
The crystal structure of β-1,2,3,4,5,6-hexachlorocyclohexane was redetermined from three-dimensional visually estimated data (285 reflections). Crystals are cubic, space group Pa3, with Z = 4, a = 1 008(1) pm.

Haloalkane Dehalogenase LinB is responsible for β- and δ-hexachlorocyclohexane transoformation in sphingobium indicum B90A

, 2006
Incubation of resting cells of Sphingobium indicum B90A, Sphingobium japonicum UT26, and Sphingobium francense Sp+ showed that they were able to transform ß- and -hexachlorocyclohexane (ß- and -HCH, respectively), the most recalcitrant ...

Enantioselective dehydrochlorination of δ-hexachlorocyclohexane and δ-pentachlorocyclohexene by LinA1 and LinA2 from sphingobium indicum B90A

, 2013
delta-Hexachlorocyclohexane (delta-HCH), one of the prevalent isomers of technical HCH, was enantioselectively dehydrochlorinated by the dehydrochlorinases LinA1 and LinA2 from Sphingobium indicum B90A to the very same delta-pentachlorocyclohexene ...
