In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

In this study, reduced androgen receptor gene methylation and shorter CAG repeats in children with premature pubarche may lead to increased hair follicle sensitivity to steroid hormones, potentially causing early pubic hair development.

Genes and hormones cause hair loss, with four genes contributing equally.

This review covers the pathophysiology, diagnosis, and treatment of nonclassic congenital adrenal hyperplasia due to P450c21, but it reports no new clinical results.

The LRRK2-G2019S mutation in Parkinson's disease has a lifetime penetrance of 25-35%, and finasteride may help reduce symptoms in adult male Tourette syndrome patients.

This article contains additional supporting information available online but presents no new research findings.

This review discusses the role of tumor suppressors in controlling tumor-associated inflammation and suggests that targeting this inflammation may counteract the effects of tumor suppressor loss.

This study suggests that the AGA risk haplotype in Europeans was driven to high frequency by positive selection, likely associated with a variant in the EDA2R gene.

This study suggests that new cells are incorporated into the dermal papilla during the early anagen phase of the hair cycle, which may influence hair growth consistency and follicle size changes.

This study found that specific SHBG gene variants, rs727428 and rs6259, were associated with PCOS in Mediterranean women, although the associations were relatively weak and do not indicate a causative role.

Finasteride may help reduce symptoms in male Tourette syndrome patients.

This review explores potential indications for prolactin receptor inhibitors beyond breast and prostate cancers, emphasizing the need for potent antibodies to further research prolactin receptor expression.

The document describes a woman with familial Parkinson's disease due to a genetic mutation, showing severe symptoms and poor response to treatment, and suggests finasteride may help reduce symptoms in Tourette syndrome.

This review discusses the pathophysiology, genetics, and management of nonclassic congenital adrenal hyperplasia, noting subfertility and hormonal issues without providing new clinical results.

This abstract contains only supplementary material information and reports no new research findings.

This study suggests that the TNF-α system may contribute to hyperandrogenism, obesity, and insulin resistance in polycystic ovarian syndrome, independent of the C850T polymorphism.

This article reviews the role of R-spondins and their receptors in bone development and metabolism, highlighting their potential modulatory effects and clinical implications for treating bone loss diseases, but reports no new clinical results.

This study suggests that the androgen receptor locus on the X chromosome may play a role in the pathogenesis of early-onset female pattern hair loss.

In this study, topical application of the SCD1 inhibitor XEN103 significantly reduced sebaceous gland size and number in mouse skin, suggesting potential local therapeutic effects for acne treatment without systemic side effects.

This paper examines crisis management models within sport marketing and sponsorship, focusing on the brand risks of athlete-triggered crises, and calls for further research in this area; it does not report new results.

This study found that 363 genes were differentially expressed in alopecia areata skin compared to non-lesional skin, suggesting T-cell mediated immune responses and distinct gene profiles related to the disease's stage.

This article reviews the evidence regarding the role of sex hormones in occult hyperadrenocorticism and reports no new findings, highlighting the unproven nature of their involvement.

This study found that a novel rare variant in ITGB6 may cause intellectual disability, alopecia, and dentogingival anomalies in a specific Pakistani family, highlighting a potential role for ITGB6 beyond enamel formation.

This study observed that patients with alopecia areata often have a T-cell receptor repertoire in skin lesions that suggests a specific antigen-driven immune response may be important in the disease's pathogenesis.

This review discusses the potential link between long-term transdermal exposure to sex hormones from antiperspirants and increased breast and prostate cancer rates, calling for further research to confirm this theory.

In this study, researchers identified specific long non-coding RNAs involved in feather development that do not follow traditional genetic inheritance patterns in chickens.

This study found that despite carrying an activating Hras mutation, hair follicle stem cells integrate into normal skin without causing tumors, unlike similar mutations in the epidermis, suggesting unique tumor-suppressing mechanisms in hair follicles.

Finasteride significantly reduced tics and obsessive-compulsive symptoms in patients with Tourette syndrome.

This study found that the L457(3.43)R mutation in the human luteinizing hormone receptor increases phosphodiesterase activity, reducing hormonal response despite elevated basal cAMP levels.

This review discusses the development of targeted therapies for basal cell carcinoma that interfere with Hedgehog signaling and reports no new research findings.
