This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study identified differentially expressed proteins and pathways potentially involved in wool bending in Zhongwei goats, with specific genes like COL6A1 and CRNN emerging as important candidates in this process.

This study revealed that chronic restraint stress in mice led to significant alterations in metabolic pathways and gene expression associated with hair growth inhibition, using metabolomics and transcriptomics analyses.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study found that a ceria nanozyme-integrated microneedles patch accelerated hair regeneration in an androgenetic alopecia mouse model more effectively than minoxidil, with reduced application frequency and minimal skin damage.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

The research identified 12 antioxidant compounds in Polygonum multiflorum roots, suggesting these as quality markers for the plant's processed roots.

This chapter reviews the roles of ethylene and auxin in seedling growth and development and reports no new experimental results; it highlights recent studies on their mechanistic crosstalk.

This study found that inhibiting the Mitochondrial Pyruvate Carrier in human scalp hair follicles caused metabolic stress that halted cell proliferation and disrupted key signaling pathways, with these effects partially reversed by an integrated stress response inhibitor.

This study reports that structural and biochemical analysis of steroid 5α-reductases clarifies how they mediate steroid reduction with NADPH, potentially aiding in designing targeted therapies.

This study observed that extracellular matrix scaffold membranes performed less effectively in wound healing for aged mice compared to younger ones, with senescent SPP1+ macrophages potentially hindering epidermal and fibroblast repair abilities.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.
