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 review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

In this study, researchers discussed how specific protein interactions in reptile skin allow for the development of protective structures like scales and scutes, which facilitated reptiles' adaptation to terrestrial environments.

This article proposes a hypothesis that KRT75, a protein found in hair follicles, was evolutionarily co-opted by ameloblasts during the development of prismatic enamel in synapsids, but reports no new results.

This paper reviews the evolution of skin appendages and keratin-associated proteins among amniotes, proposing a model for their genetic divergence without new experimental results.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This research found that variations in the KRTAP gene family are likely responsible for the diverse hair phenotypes seen among mammals, influenced by gene repertoire differences, expression, and evolutionary factors.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

This perspective highlights the potential of reptile integument as an experimental model to understand the evolution of amniote skin structures, but reports no new research findings.

This review provides an overview of the molecular evolution of corneous beta-proteins in reptiles and birds, highlighting their distinct genetic origin and role in epidermal structures, but reports no new results.

This study identified the distribution of keratin-associated proteins during cornification in the epidermis of reptiles, revealing unique structural characteristics in sauropsid keratin proteins compared to other vertebrates.

This article discusses a hypothesis on the development and evolution of scales, hairs, and feathers from fish to amniotes, based on regions of dermo-epidermal interactions in skin, but reports no new findings.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

This study suggests that the keratins found in reptile and bird skin appendages evolved independently from mammalian hair keratins, highlighting convergent evolution in these species.

This study found that the Florida worm lizard has lost certain genes associated with claw development, which are present in other lizard species with claws, suggesting a link between the evolution of their limbless body and the loss of claw-related genes.

This study identified a new S100 fused-type protein, scaffoldin, in reptiles and birds and suggests that SFTP-positive epithelia serve as scaffolds for the growth of various skin appendages, indicating a common evolutionary origin.

In this study, researchers observed that the epidermal specializations on the tail scales of Lygodactylus lizards, including sensory organs and specific secretory glands, are fully restored with similar structure and distribution on regenerated tails.

In this study, the researchers found that mammalian hair likely evolved through the adaptation of existing structural proteins, as similar cysteine-rich α-keratins were identified in chicken and lizard genomes, suggesting pre-mammalian origins.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

This study provides evidence that human sweat gland myoepithelial cells contain stem cells capable of self-renewal and differentiating into sweat gland luminal cells.

This study found that the main structural proteins of tree frog toe pads, which aid in their adhesive properties, are alpha keratins that have evolutionary origins in early tetrapods.

This review discusses the biochemical and biological functions of histone demethylases and their potential involvement in human diseases, including cancer, but reports no new findings.

This review discusses the roles and mechanisms of chromatin remodelers and their subunits in mammalian development, but reports no new experimental results.

This study suggests that cerebrospinal fluid levels of the neurosteroids allopregnanolone and pregnanolone correlate negatively with PTSD and negative mood symptoms, with potential sex-specific differences in synthesis enzyme blocks.

This study found that topical valproic acid significantly increased hair count in male patients with moderate androgenetic alopecia compared to placebo over 24 weeks.

This review examines how fibroblasts contribute to regeneration in various organs and explores the potential of reverting adult fibroblasts to a fetal-like state for regenerative therapies, but reports no new empirical findings.

This review discusses the regulation and dynamics of the Wnt/β-catenin signaling pathway in development, pluripotency, and cancer, highlighting potential mechanisms and future research directions, but reports no new results.

This study found that altering neonatal neurosteroid levels affected anxiety and aversive learning in adult rats, possibly through changes in hippocampal GABAergic functions.

This study found that using valproic acid during radiotherapy for glioma was associated with delayed hair loss and improved survival outcomes.
