This study identified a cytochrome P450 enzyme, CYP-pa1 from Pseudonocardia autotrophica, as responsible for the specific hydroxylation of cyclosporin A at the 9th N-methyl leucine, suggesting potential for biotechnological applications.

This review discusses the role of peptidylarginine deiminases in skin homeostasis and diseases, particularly in keratinocyte differentiation and hair disorders, but presents no new experimental findings.

This study found that Annurca apple polyphenolic extracts reprogram hair follicle metabolism in mice, enhancing mitochondrial activity and keratin production while inhibiting some metabolic pathways.

This study synthesized and characterized new 2-hydroxypyrrolidine/piperidine derivatives using FeCl₃·6H₂O as a catalyst, but it reports no biological or clinical results.

This study found that mutations in phosphorylation sites on the PIN3 protein disrupt its phosphorylation and subcellular trafficking, affecting auxin transport and root growth in a cell-type-specific manner.

In this study, disruptions in phospholipase A2 activity in Arabidopsis thaliana significantly impaired the plasma membrane localization of PIN proteins, affecting auxin transport and root development.

This study reports a new one-pot method for synthesizing chromeno-pyrimidine-N-oxides with high yield from 4-chloro-3-formylcoumarin and aromatic carboximide oximes, confirmed by X-ray analysis.

This study found that mice can synthesize inositol, but this ability is impaired when pantothenic acid is lacking in their diet.

This research outlines a chemical synthesis process for Finasteride, detailing the conversion of pregnadienolone acetate through various chemical reactions and modifications.

This case study describes a six-month-old boy diagnosed with Netherton syndrome, featuring ichthyosiform erythroderma and alopecia, possibly linked to aminoaciduria.

In this study, the researchers report that a modified epimorphin-derived peptide shows potential for hair follicle regeneration, especially when used with 1% minoxidil in mice.

This study found that the enzyme glutamine synthetase is distributed throughout the epidermis and its activity in keratinocytes is notably increased by ammonium ions, suggesting the skin serves as a reservoir for glutamine generation.

This study found that enzymatic conversion of Arg-51 in S100A3 protein to citrulline promotes homotetramer assembly, potentially increasing Ca²⁺ binding required for hair cuticular barrier formation.

This study found that pimozide, d-butaclamol, and pituitary pars intermedia grafts darken hair color in agouti C3H Avy mice, suggesting dopaminergic inhibition influences peptide-controlled hair color cycling.

This opinion from the EFSA Panel concludes that the health claim regarding spermidine prolonging the anagen phase of the hair cycle does not meet regulatory criteria as it is related to disease treatment.

This study observed that POMP is strongly expressed in the root sheath hair follicles of Liaoning Cashmere goats and its expression can be regulated by certain factors, which may influence cashmere growth.

This study found that Plant Elicitor Peptides enhance root hair growth through a mechanism independent of their known receptors, with PROPEP2 playing a key role in this process by influencing gene expression related to root hair formation.

This study developed a new synthetic route for finasteride that omits the costly reagent 2,2′ dipyridyl disulfide, achieving an overall yield of 16%.

This study observed that glycine inhibited root growth and stimulated root hair development in habanero pepper seedlings, with ethylene signaling suggested to mediate these effects.

Pili annulati is caused by a protein metabolism disorder affecting hair structure.

In this study, α-MSH and cyclic AMP were found to stimulate melanogenesis in hair follicle cultures, while cyclic GMP and melatonin inhibited melanin production but not tyrosinase activity.

This study found extensive co-evolution of polyglutamine repeat lengths in neural protein clusters, highlighting their potential role in neurocognitive variation and neuropsychiatric disease development.

This review discusses studies on hair growth and protein synthesis in hair follicles, highlighting the differing responses of mohair and cashmere goat follicles to signaling molecules, biotin, and amino acids, but contains no new results.

This study found that good quality protein supplements or rumen-protected methionine increased fiber yield in Angora goats and, to a lesser extent, in Cashmere goats.

This study found that prostaglandin metabolism enzymes are present in human hair follicles, suggesting a potential role in hair growth and differentiation, with some expression differences between men and women.

This study reports that hypomorphic alleles of the Ass1 gene in mice resemble human CTLN1, providing a potential model for preclinical studies and indicating that standard treatments for CTLN1 can rescue phenotypes.

This study found that inhibiting arachidonate 12-lipoxygenase (ALOX12) may enhance hair cuticle maturation by increasing S100A3 protein citrullination and promoting cuticular differentiation in isolated human hair follicles.

In this study, pantothenic acid at 20 μg/ml was observed to promote dermal papilla cell proliferation and migration, likely through up-regulation of ID3 and inhibition of Notch signaling.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.
