In this retrospective cohort study, researchers found that persistent discontinuation of gender-affirming hormones among transgender adolescents was rare, mainly due to achieving gender expression goals or access issues, with very few reidentifying with their birth-assigned sex.

This research found that the widely used herbicide atrazine may alter Northern leopard frog development, affecting metamorphosis success, sex ratio, and hormone-related gene expression.

This study found that early postnatal androgen activity affects the long-term expression of hormone receptors differently in female Wistar rats, influencing neural system programming during development.

This study found that normal human epidermis expresses TSH and may be an indirect target of TSH signaling, with expression regulated by endocrine controls of the hypothalamic-pituitary-thyroid axis.

In this study, male rats with spinal cord injury that received either E2 or DHT supplementation both showed restored expression of respiratory neuroplasticity following acute intermittent hypoxia, with E2 also enhancing overall breathing recovery.

In this study, nandrolone decanoate treatment in rats caused persistent diestrus and altered steroid receptor expression and sex hormones, especially at higher doses, with partial reversibility at lower doses over time.

In this animal study, rats treated with recombinant human growth hormone (at both low and high doses) experienced quicker burn wound healing than controls, with increased micro vessel density and altered expression of vascular endothelial growth factor, alongside changes in oxidative stress and inflammation markers.

This study found that stimulation with certain neurotransmitters and hormones suggests the involvement of 5α-reduced neurosteroids in glial cell differentiation in rat C6 glioma cells.

In this study of hydroponically grown tomatoes, the authors reported that adding melatonin at 10-30 μmol·L-1 effectively enhanced lateral root development, root hair growth, biomass accumulation, and root activity by influencing related gene expression and hormone levels.

In this study, physiological levels of free T3 significantly enhanced the survival of human hair follicles in vitro.

This study suggests that αMSH may play a regulatory role in human dermal papilla cells, potentially influencing immune and inflammatory responses in hair follicles, which could contribute to inflammatory alopecia.

This review discusses the expression of circadian genes in hair follicles and their potential for monitoring circadian-rhythm-related conditions, reporting no clinical results; the authors suggest combining hair sampling with other assessments for better insight.

This research suggests that testosterone-induced expression of TGF-beta1 and type I procollagen may lead to perifollicular fibrosis in androgenetic alopecia, with finasteride inhibiting this process as a possible mechanism for its effects.

TSH influences keratin expression in human hair follicles.

This study observed that differences in the expression of genes related to lipid metabolism may play a major role in determining wool fiber diameter in sheep.

This study suggests that human skin locally synthesizes active sex steroid hormones, impacting inflammation, cell behavior, and wound healing, with potential implications for therapies in aging and impaired wound recovery.

This study found that thyroxine modulates peripheral molecular clock gene expression in human hair follicles, which may have implications for treating clock-related diseases in patients with thyroid dysfunction.

This study found that corticotropin-releasing factor influences cytokine expression related to hair growth in human dermal papilla cells and suggests CRF receptor antagonists could be potential treatments for stress-induced hair loss.

This paper describes the hGRα gene structure and its expression, focusing on the functional properties of the longest GRα isoform, but reports no new results.

This review discusses the structure, expression, regulation, and potential functions of the nuclear receptor coactivator NcoA4 in cancerous and non-cancerous pathologies, but reports no new results.

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 patients with ovarian metastases from breast cancer had a better prognosis after tumor debulking if they exhibited high estrogen and progesterone receptor expression in both the primary tumor and metastases.

This study found that the hHa7 gene in hair follicle trichocytes is the first identified to have its expression directly regulated by androgens, suggesting it as a marker for androgen action on hair follicles.

This review discusses the role of steroid sulfatase in steroid hormone metabolism and highlights the need for more research on its expression and regulation, especially regarding hormone-dependent tumors.

This study found that the estrous cycle influences the effect of the δ-GABAAR agonist THIP in reducing binge drinking behavior in female mice, with receptor expression elevated during diestrus.

In this review, researchers highlighted that natural polyphenolics like flavonoids and resveratrol may help enhance testosterone production in aging males by boosting the expression of the Star gene in Leydig cells, potentially preventing age-related degenerative conditions linked to testosterone insufficiency.

This study provides evidence that long-term deregulation of the circadian rhythm in humans affects the regenerative properties of skin and hair precursor cells by altering clock pathway protein expression.

This study observed that specific genes in cashmere goat skin exhibit a seasonal rhythm, potentially adapting to environmental light changes, which may affect downstream gene expression and physiological processes.

This study suggests that human scalp hair follicles express erythropoietin and its receptor, up-regulating receptor expression under hypoxic conditions, and may mimic another hypothalamus–pituitary axis equivalent involving the TRH-TSH system.

This study found that specific SNPs in the CYP19A1 gene were associated with Female Pattern Hair Loss in Egyptian women, with altered CYP19A1 gene expression and higher frequencies of related genotypes observed in patients compared to controls.
