This review found that while elevated DHEA levels are observed in some women with PCOS, especially those with hyperandrogenism, inconsistencies across studies suggest that standardized measurement and analyses are needed to clarify DHEA's role as a biomarker and factor in PCOS pathophysiology.

This source highlights that fractional CO2 laser, as a minimally invasive technology, shows significant benefits in treating various skin and mucosal conditions by improving therapeutic outcomes, shortening recovery times, and enhancing precise personalized interventions through emerging technologies like AI and biomarker monitoring.

This study identified three hub genes—BMP4, POSTN, and WNT5A—that are closely associated with keloid fibroblast hyperplasia, suggesting they may serve as potential biomarkers for inhibiting this condition. Further research is necessary to fully understand their roles in keloid development.

This review discusses the role of extracellular vesicles in psoriasis pathogenesis and their potential as therapeutic agents or drug delivery systems, but it reports no new clinical findings.

This review highlights potential links between inflammatory skin diseases like psoriasis and atopic dermatitis and hypercoagulable states, but notes that more research is needed to understand these connections and their clinical implications.

This study found distinct proteomic differences between male and female androgenetic alopecia, highlighting sex-specific molecular pathways and potential biomarkers for pattern hair loss.

This study found that serum FABP4 levels were significantly higher in alopecia areata patients compared to healthy controls and may correlate with disease severity.

This study identified 193 plasma proteins associated with prostate cancer risk, validating 20 high-risk proteins including KLK3, and pinpointed potential drug targets like HSPB1, RRM2B, and PSCA through genetic analysis, offering new insights for biomarkers and treatments.

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.

This study used Mendelian randomization analysis to identify Scyllo-inositol and Alpha-ketoglutarate as potential protective factors and Heme and 2-palmitoylglycerophosphocholine as risk factors for androgenic alopecia, suggesting a causal link between these metabolites and the condition.

This review highlights the diagnostic potential and therapeutic prospects of exosomes, discussing their use in managing chronic immune-mediated skin conditions, alopecia, and wound healing through their capacity to deliver regulatory molecules between cells.

This study found that patients with alopecia areata had significantly higher levels of circulating DNA for certain cytokines compared to healthy controls, suggesting that increased circulating DNA may be linked to hair follicle damage in these patients.

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.

The researchers in this study identified molecular mechanisms involved in frontal fibrosis alopecia, highlighting immune response and fatty acid metabolism, and developed a four-gene diagnostic model showing high accuracy in distinguishing affected individuals from controls.

In this study, AGA patients exhibited distinct lipidomic profiles and higher metabolic syndrome prevalence compared to controls, with certain lipids correlated to key AGA-related factors like DHT, PGD2, and TGF-β1.

This study analyzed scalp hair proteins from healthy children and their mothers, finding that non-structural proteins could serve as promising biomarkers for understanding long-term developmental changes and health status linked to early childhood experiences.

Results are not reported for this study, which used a directed acyclic graph to analyze the association between chest hair amount and prostate cancer, adjusting for age and ancestry.

This study suggests that serum paroxonase 1 levels are decreased in patients with androgenetic alopecia and may serve as a useful biomarker for this condition.

This study found that A-FABP serum levels were significantly higher in male patients with androgenetic alopecia compared to controls, and the authors concluded that A-FABP could serve as a biomarker for early detection of this condition.

This study found that male patients with androgenetic alopecia had higher serum levels of Zinc Alpha 2 Glycoprotein than healthy controls, suggesting its potential role in the disease's pathophysiology.

This study found that tissue transcriptomics and a normalization approach can effectively cluster nine inflammatory skin diseases and identify specific biomarkers, including PTEN as a marker for cutaneous lupus erythematosus.

The document concludes that inflammation markers can be used in diabetes, vitamin D3 affects immune pathways, hyperthyroidism changes hormone levels, androgen levels help diagnose Adrenocortical Carcinoma, erectile dysfunction is linked to diabetes, hypogonadism is common in HIV-infected males, and hormones can be biomarkers for various conditions.

This case control study investigated serum IL-17A levels in alopecia areata patients compared to healthy controls to explore its potential role in the disease's pathogenesis.

This study found that mTOR gene expression was significantly higher in individuals with acne vulgaris compared to healthy controls, suggesting its potential as a biomarker for acne prognosis and treatment response.

This study observed that repeated hair follicle sampling is feasible and reliable for measuring FMR1 mRNA and FMRP in individuals with Fragile X syndrome, supporting its use in longitudinal studies.

This study found that repeatedly collecting hair follicles from individuals with fragile X syndrome is feasible for measuring FMR1 and FMRP levels in both home and office settings.

This study found that plasma Claudin 3 levels were linked to alopecia areata severity among patients compared to healthy controls.

This study found that serum IL-17A levels were significantly higher in patients with alopecia areata compared to healthy controls and correlated with disease severity and activity.

This study identified non-structural proteins in preschool children's scalp hair that suggest potential biomarkers for brain development, immune function, and stress response with heritability and age-related differences.

This study found that ageing in women leads to significant structural and biological changes in the scalp hair follicle environment, which may affect hair growth.
