research Local Actions of Thyrotropin-Releasing Hormone Regulate Hair Color
TRH in hair follicles can influence hair color by increasing melanin.
research SASH1 Mutations and Hereditary Disorders of Pigmentation: Review of Literature
SASH1 gene mutations are linked to various inherited skin pigmentation disorders.
research An implication for post-transcriptional control: Reciprocal changes of melanocortin receptor type 2 mRNA and protein expression in alopecia areata
Alopecia areata may involve stress-related changes affecting hormone receptors, leading to reduced cortisol production.
research Down-regulation of Melanocortin Receptor Signaling Mediated by the Amino Terminus of Agouti Protein in XenopusMelanophores
Agouti protein affects melanocortin receptors through competitive antagonism and receptor down-regulation.
research 457 Impact of alpha-melanocyte-stimulating hormone on mitochondrial function in human dermal fibroblasts
Alpha-MSH affects mitochondrial function, and MC1R mutations may increase skin aging.
research A syndromic extreme insulin resistance caused by biallelic POC1A mutations in exon 10
Mutations in the POC1A gene can cause a unique form of extreme insulin resistance and short stature.
research Melanocortin receptors in fibroblastic cell types of the skin –in vitro and in vivo expression and functional relevance
MC-1R is present in skin cells and may help reduce inflammation.

research Molecular, immunological, enzymatic and biochemical studies of coproporphyrinogen oxidase deficiency in a family with hereditary coproporphyria.
A new gene mutation causes hereditary coproporphyria with reduced enzyme activity.
research Non-pigmentary actions of alpha-melanocyte-stimulating hormone--lessons from the cutaneous melanocortin system.
Alpha-melanocyte-stimulating hormone helps manage skin inflammation and protect against UV damage.
research Expression of melanocortin receptors on cutaneous fibroblastic cells – collagen and beyond
MC-1R in skin cells may influence inflammation and collagen production.
research A case of systemic mastocytosis - an ultrastructural and immunohistochemical study of the dermal mast cells in relation to activation of the epidermal melanin unit
Prednisone reduces organ mast cell infiltration but does not alter the abnormal appearance of mast cells in systemic mastocytosis.
research ACOD1 deficiency promotes DDX1 methylation–mediated mitochondrial dysfunction and dermal papilla cell senescence in androgenetic alopecia
ACOD1 deficiency worsens hair loss by causing cell aging and mitochondrial problems, but 4-OI may help.
