research The Local Hypothalamic–Pituitary–Adrenal Axis in Cultured Human Dermal Papilla Cells
Stress hormone CRF can cause hair loss by affecting hair growth cells and hormones.
research Alopecia Areata: Hyperactivity of the Hypothalamic–Pituitary–Adrenal Axis Is a Myth?
The study found no significant difference in stress hormone levels between people with alopecia areata and healthy individuals, suggesting that the disease is not caused by an overactive stress response system.
research The Circular RNA CircCOL1A1 Functions as a miR-149-5p Sponge to Regulate the Formation of Superior-Quality Brush Hair via the CMTM3/AR Axis
A specific RNA molecule, circCOL1A1, affects the growth and quality of goat hair by interacting with miR-149-5p and influencing cell growth pathways.
research Major Approaches of Molecular and Physiopathological Mechanisms for Hormonal Treatment of Melasma: A Systematic Review
Estrogens and progesterone are key in regulating melasma pigmentation.
research Novel Mechanism of UVB-Mediated Pigmentation Through the Axis of ATP-P2X7
Scientists discovered a new way UVB light increases skin pigmentation through the ATP-P2X7 pathway.
research Prolactin: An Emerging Force Along the Cutaneous–Endocrine Axis
Prolactin may play a significant role in skin and hair health and could be a target for treating skin and hair disorders.
research Critical Role of ATP-P2X7 Axis in UV-Induced Melanogenesis
ATP increases melanin production in skin after UV exposure, with the P2X7 receptor being crucial for this process.
research Activation of the OVOL1-OVOL2 Axis in the Hair Bulb and Pilomatricoma
The genes OVOL1 and OVOL2 are important for hair growth and may be involved in a type of skin tumor.
research Indications for a Brain-Hair Follicle Axis: Inhibition of Keratinocyte Proliferation and Up-Regulation of Keratinocyte Apoptosis in Telogen Hair Follicles by Stress and Substance P
Stress can cause hair loss by negatively affecting hair follicles and this effect might be reversed with specific treatments.
research Genetic Variation in the Human Androgen Receptor Gene Is the Major Determinant of Common Early-Onset Androgenetic Alopecia
Genetic variation in the androgen receptor gene mainly causes early-onset hair loss, with maternal inheritance playing a key role.
research The Bright Side of Fibroblasts: Molecular Signature and Regenerative Cues in Major Organs
Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.
research Skin Adipocyte Stem Cell Self-Renewal Is Regulated by a PDGFA/AKT Signaling Axis
PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.
research LncRNA-PCAT1 Maintains Characteristics of Dermal Papilla Cells and Promotes Hair Follicle Regeneration by Regulating miR-329/Wnt10b Axis
PCAT1 helps hair growth by controlling miR-329/Wnt10b.
research Neuroendocrinology of Human Scalp Hair Follicles: Growth Hormone-Releasing Hormone Stimulates Hair Growth and Controls a Fully Functional Intrafollicular Hypothalamic-Pituitary-Somatotropic Signaling Axis
Growth hormone-releasing hormone (GHRH) boosts hair growth and human scalp hair follicles have their own growth hormone system.
research Human Hair Follicles Operate a Functional Peripheral Equivalent of the Hypothalamic-Pituitary-Somatotropic Axis Ex Vivo
Human scalp hair follicles can produce hormones and have a system similar to a brain-body communication network.
research Disorders of Ovulation
Ovulation disorders are a major cause of infertility and menstrual problems in women.
research Physiology of Male Gonadotropic Axis and Disorders of Sex Development
Understanding genes and hormones is crucial for managing male puberty and sex development disorders.
research Polycystic Ovarian Syndrome in Taiwanese Women
Obesity is a major risk factor for insulin resistance in Taiwanese women with PCOS, which is also an independent risk factor for metabolic syndrome.
research The Vitamin B5/Coenzyme A Axis: A Target for Immunomodulation?
Vitamin B5 and coenzyme A may help regulate the immune system and could improve treatments for chronic diseases and cancer.
research Polycystic Ovary Syndrome: Comprehensive Overview and Diagnostic Criteria
PCOS is a complex condition with major health impacts, needing more research for better diagnosis and treatment.
research Androgen Receptor Gene CAG and GGN Polymorphisms in Infertile Nigerian Men
Certain gene variations are not a major cause of male infertility in Nigerian men.
research COVID-19 Infection Is a Major Cause of Acute Telogen Effluvium
COVID-19 infection can significantly cause temporary hair loss.
research Transgenic Kallikrein 14 Mice Display Major Hair Shaft Defects Associated with Desmoglein 3 and 4 Degradation, Abnormal Epidermal Differentiation, and IL-36 Signature
Mice with extra human KLK14 had hair and skin problems, including weaker cell bonds and inflammation, linked to Netherton syndrome.
research Single-Cell Transcriptomics Reveals a Senescence-Associated IL-6/CCR6 Axis Driving Radiodermatitis
Blocking certain immune signals can reduce skin damage from radiation therapy.
research Role of the Wnt Signaling Pathway in Keratoacanthoma
