,
February 2003 in “Veterinary Dermatology” This narrative review discusses the use of cyclosporin for various skin diseases in small animals and notes minimal side effects at therapeutic doses, but reports no original clinical findings.
57 citations
,
June 2003 in “American Journal of Physiology-cell Physiology” This study found that cyclosporin A treatment enhances hair growth in mice by inhibiting calcineurin-NFAT1 activity, which alters keratinocyte differentiation and apoptosis-related gene expression in hair follicles.
56 citations
,
April 2019 in “The Plant Journal” This study found that CNGC 6, CNGC 9, and CNGC 14 are crucial for maintaining calcium oscillations necessary for normal root hair growth in plants, with mutations leading to defects like swelling and bursting.
