research Expression of Matrix Metalloproteinases and Tissue Inhibitor of Matrix Metalloproteinases in the Hair Cycle
The study investigated the expression of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) during the hair cycle in mice. It found that MMP-2 and MMP-9 had elevated mRNA and protein expression levels during the anagen phase and decreased levels during the catagen and telogen phases. Their activities fluctuated throughout the hair cycle. TIMP-1 and TIMP-2 expression levels were negatively correlated with MMP-9 and MMP-2, respectively. Immunohistochemical analysis showed that MMP-2 and TIMP-2 were present in all hair follicle structures, while MMP-9 and TIMP-1 were localized to specific areas. These findings suggested that MMP-2 and MMP-9 played significant roles in the hair growth cycle.
research Alkaline Ceramidase 1 Protects Mice from Premature Hair Loss by Maintaining the Homeostasis of Hair Follicle Stem Cells
The study demonstrated that the alkaline ceramidase 1 (ACER1) gene was crucial for maintaining the homeostasis of hair follicle stem cells (HFSCs) in mice by regulating ceramide metabolism. Mice deficient in the Acer1 gene exhibited elevated levels of ceramides and sphingoid bases, leading to progressive hair loss. The loss of Acer1 resulted in a widened follicular infundibulum and a reduction in HFSC survival and stemness. These findings suggested that ACER1 was essential for preserving the structure and function of hair follicles by controlling ceramide metabolism in the epidermis.

research Molecular, Immunological, Enzymatic and Biochemical Studies of Coproporphyrinogen Oxidase Deficiency in a Family with Hereditary Coproporphyria
The study focused on a 27-year-old woman with hereditary coproporphyria, characterized by recurrent renal pain, dark urine, and hair loss, but no photosensitivity. Elevated urinary porphyrin metabolites and fecal studies confirmed the diagnosis, with decreased coproporphyrinogen oxidase activity at 35% of normal levels. Her mother and sisters were identified as heterozygous carriers of the condition, showing reduced enzyme activity up to 50%. A novel mutation was discovered in the coproporphyrinogen oxidase gene, involving a cytosine to thymine transversion at nucleotide position 854. Immunological studies indicated decreased enzyme protein concentrations in the patient and her family members.
