In this study, significant upregulation of the genes SFRP2 and PTGDS was found in bald hair follicles of female pattern hair loss patients compared to non-bald follicles, suggesting these genes may be biomarkers and play a role in hair loss for this condition.

In this study, researchers identified a mutation in mice that causes hair loss and immune system issues, located on chromosome 18.

This study identified three novel genetic loci associated with PCOS and found similar genetic architecture across different diagnostic criteria, with evidence suggesting genetic links between PCOS and various metabolic and psychological traits.

This study found that fruit extracts from certain Egyptian Sabal species demonstrated significant anti-androgenic activity and potential therapeutic effects against benign prostatic hyperplasia in rat models and cell lines.

This study identified three new genetic loci associated with PCOS and found a similar genetic structure across different diagnostic criteria, suggesting a genetic basis for shared metabolic traits and potential causal links to other conditions.

This study identified histologic lesions and a defect in adhesion molecules causing hair loss in mice with the bal mutation, linked to a mutation in the desmoglein 3 gene.

In this study, male-pattern baldness was strongly associated with a higher risk of keratinocyte cancers, particularly squamous cell carcinoma and melanoma, likely due to increased sun exposure on the scalp rather than androgen levels.

In this study, researchers identified 18 genetic associations with scalp and facial hair traits in Latin Americans, including novel loci for hair greying and balding, with implications for understanding hair evolution.

This study found that brothers of women with PCOS exhibit elevated DHEAS levels, indicating a potential familial genetic trait, but did not show increased rates of premature balding.

This article discusses the evolution and variation of hairlines in men and women across different ages, introducing a modeling system to standardize the anatomical description of hairlines, without reporting new experimental findings.

This study discusses patterns of androgenetic alopecia in Indian men but reports no new clinical findings.

This study found that higher levels of adiponectin were associated with reduced inflammation and osteolysis, suggesting potential therapeutic benefits for patients with aseptic loosening of joint replacements.

This article discusses the hypothesis that mechanisms driving androgenic alopecia may reduce the risk and proliferation of prostate cancer by increasing prostaglandin D2 levels but presents no new clinical findings.

This study found that parents of women with PCOS have a higher prevalence of insulin resistance and Type II diabetes than parents of healthy women.

This paper discusses how studying hair follicles in the balding scalp could reveal fundamental biological processes, without reporting new experimental findings.

In this study conducted at Saveetha Dental College, researchers found that the severity of male androgenetic alopecia, as graded by Norwood's classification, increased with age, although other factors such as genetic or hormonal influences were not assessed.

Hormones and genetics affect hair growth and patterns, with some changes reversible and others not.

Hair health is influenced by genetics, aging, and environmental factors, with proper care needed to maintain it.

This review discusses the genetic and hormonal factors involved in androgenetic alopecia but reports no new research findings.

The researchers reported two brothers with a new variant of X-linked trichothiodystrophy associated with an RNF113A gene mutation, highlighting features such as intellectual disability and growth failure, but without previously reported endocrinological or genital abnormalities, underlining the importance of genetic counseling for such variants.

This article reviews the genetic and phenotypic characteristics of Trichothiodystrophy and discusses the associated DNA repair defects, but does not report new clinical findings.

This article discusses how dihydrotestosterone (DHT) contributes to male pattern baldness by affecting genetically sensitive hair follicles and includes no new research findings.

This study found that neurotrophins produced by balding dermal papilla cells inhibited both their proliferation and hair follicle growth in vitro, suggesting a potential role in androgenetic alopecia.

No genetic link between prostaglandins and hair loss found.

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

This study suggests that down-regulation of vasculature-related genes in dermal papilla cells from balding scalps might contribute to the development of androgenetic alopecia.

This study, conducted among Egyptians, found a borderline significant association between the Stul polymorphism of the androgen receptor gene and androgenetic alopecia in males, with higher androgen receptor expression in balding scalp areas.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

This study identified SFRP2 and PTGDS as potential biomarkers for female pattern hair loss, finding these genes consistently upregulated in bald hair follicles from all 18 patients, which may contribute to understanding the condition's pathogenesis and developing targeted treatments.

In this study of a TRPS type I patient, many genes related to keratin and hair development were down-regulated in balding scalp areas, providing new insights into TRPS and hair morphogenesis.
