Terrestrial vertebrates have balanced keratin gene clusters, unlike teleost fish.

This study identified molecular differences between dysplastic nevi and common melanocytic nevi, including altered keratinocyte differentiation, increased hair follicle-related molecule expression, and distinct immune microenvironment characteristics in dysplastic nevi.

This study found that human hair follicles can function like a peripheral hypothalamic-pituitary-adrenal axis, synthesizing cortisol in response to corticotropin-releasing hormone and adrenocorticotropic hormone stimulation.

This article discusses the complexities of diagnosing pituitary dependent hyperadrenocorticism in dogs and reports no new clinical findings, highlighting issues with varied symptoms and episodic hormone secretion complicating diagnosis.

This review discusses the difficulty of diagnosing hypothyroidism due to its diverse, nonspecific symptoms that can vary greatly among patients and often mimic other conditions, which may require healthcare providers to be vigilant across various specialties to recognize and diagnose the condition effectively.

In this study, researchers found that the EDMTFH protein is present in specific layers of the chicken embryo skin and feathers, suggesting its role in feather mechanics and development.

This study developed a novel multi-scale image descriptor using dictionaries for classifying histological images, achieving average recall and precision measures of 0.81 and 0.86 in identifying specific skin structures and pathologies.

This study observed in mouse skin that trichohyalin granules in hair follicles transform into filamentous structures as inner root sheath cells differentiate and cornify.

This study observed that while dexamethasone-cyclophosphamide pulse therapy is relatively free from hypertension and diabetes compared to conventional steroids in pemphigus patients, it frequently causes generalized weakness and flushing.

This source explains that Equine Cushing’s disease, or PPID, in horses is due to the degeneration of brain cells producing dopamine, leading to elevated cortisol levels and characteristic symptoms; it outlines diagnosis methods and emphasizes life-long pergolide treatment to manage the condition.

This study found that the mutant hairless rhino bald protein in mice interacts with the vitamin D receptor but cannot repress its transactivation and shows abnormal cellular localization.

This study found that dihydrotestosterone treatment in female rats altered anterior pituitary gland gene expression, with significant repression of prolactin and inhibition of GnRH receptor gene expression, suggesting specific hormone production changes.

This study found that medullary cell content in mammal hair evolves from an amorphous form to a biphasic phase, with human and anthropoid hair containing both macrofibrils and microfibrils.

This study demonstrated that elevated glucocorticoid levels in transgenic mice led to pancreatic exocrine cells transforming into hepatocyte-like cells, resulting in pancreatic dysfunction.

This study found that human scalp hair follicles can respond to corticotropin releasing hormone stimulation similarly to the classical HPA axis, including up-regulating cortisol production and activating neuroendocrine feedback loops.

This study found that in mink, the pituitary gland is essential for normal seasonal pelage cycles, and manipulating hormone levels can affect hair growth and type.

This study found that brindled mottled mice, a model of Kinky hair syndrome, exhibited abnormal development of catecholamine neurons, with increased TH-immunoreactive neurons and altered neurochemical profiles compared to controls.

This study found that dexamethasone treatment inhibited the inflammatory response and the induction of ornithine decarboxylase activity in mouse skin after TPA application, although the effect on ODC was weaker during the hyperplastic stage.

This case study describes an unusual instance of separate trichoadenoma and melanocytic naevi occurring simultaneously on the face, with the cause of their association remaining uncertain.

This report describes a 3-year-old boy with a potential new neurocutaneous syndrome characterized by unilateral alopecia, ipsilateral hemimegalencephaly, and intractable seizures.

This study found that Brandt's hedgehog has the thickest skin on its back and the thinnest on the cloacal region, with sebaceous and sweat glands primarily located in the nostril area.

This study identified a monoclonal antibody, HKN-2, that recognizes specific cells in human skin and may indicate a common antigenic determinant between hair and other skin epithelial tissues.

TSH influences keratin expression in human hair follicles.

This case study reports a 33-year-old man with autoimmune thyroiditis and alopecia universalis experiencing reversible CNS demyelination, possibly due to autoimmune activity against CNS antigens.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.
