This study found that osteopontin expression was significantly higher in alopecia areata lesions compared to healthy controls, suggesting it may play a role in the disease's pathogenesis.

This review discusses factors affecting hair aging, such as inflammation and UV exposure, and examines potential anti-aging benefits of antioxidants and nutraceuticals for hair, but reports no new clinical results.

This study conducted a meta-analysis of gene expression data from alopecia areata patients, identifying 5109 differentially expressed genes and highlighting enriched pathways like JAK-STAT signaling, providing insights into the disease's pathogenesis and potential treatment targets.

This study suggests that administering SH-MSCs gel might decrease IL-6 expression and increase TGF-β expression in alopecia-like rats, indicating potential for alopecia therapy.

This study assessed Ageratum conyzoides gel's efficacy in reducing hair loss and improving quality of life in adults with pattern baldness, finding that it decreased temporal recession and improved hair-related distress scores, with a significant reduction in 5α-reductase expression and PGD2 release in vitro.

This study demonstrated that antigens from the skin bacterium Staphylococcus epidermidis can stimulate CD8+ T cells, which in turn enhance wound healing.

In this study, the authors concluded that the TS-associated polyomavirus may disrupt Wnt/β-catenin signaling, likely contributing to abnormal hair follicle formation in trichodysplasia spinulosa.

Opioid use may lower PSA levels, suggesting a possible role in prostate cancer control; PSA testing is useful for detecting prostate cancer; serum triglycerides are not linked to prostate cancer risk; and higher urethral PSA levels may be associated with local hormone activity.

This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.

In this study, thymosin beta4 over-expression in transgenic mice was linked to accelerated hair growth and abnormal tooth development, suggesting roles in hair and tooth physiology.

This study suggests that immunohistochemistry of keratin and involucrin expression can aid in distinguishing malignant trichilemmoma from other tumors previously diagnosed as such.

This study found that human skin expresses proenkephalin, whose expression is upregulated by environmental stress and varies in pathological conditions, increasing in psoriasis and decreasing in melanocytic tumors.

In this study, treatment with finasteride altered the expression patterns of antioxidant enzymes in the epididymis of rats, potentially affecting its protective function for spermatozoa.

In this study, serum PSA levels were higher in women with PCOS, suggesting it may serve as a marker for hyperandrogenism in this condition.

This study found that increased PSA levels in women with hyperandrogenism may serve as a diagnostic marker, comparable to free testosterone levels.

This study found that during late pregnancy in rats, there is an increase in extrasynaptic GABA A receptor number in granule cells of the dentate gyrus, linked to hormonal fluctuations.

This study suggests that S100A4 and S100A6 proteins may play key roles in activating stem cells for hair follicle regeneration in mice.

This review discusses the structure, expression, regulation, and potential roles of NcoA4 in cancer and other pathologies, reporting no new experimental findings.

This study found that local androgen biosynthesis and metabolism in human sebaceous glands play a crucial role in sebum synthesis and secretion.

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

This study found that ZP4 expression was highest among PCOS patients with regular menstrual cycles, which may be linked to mature follicle presence, but no correlation with clinical indices was observed.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This study found that serum PSA levels are higher in hirsute women and can be significantly reduced by antiandrogen treatment, suggesting PSA as a marker of androgen action in females.

This study found that keratins 5, 7, 8, and 19 are expressed in human trophoblast cells while vimentin is solely expressed in stromal-mesenchymal cells, aiding in placental cell type identification.

This study found that CK15 is an unreliable marker for assessing bulge zone integrity in cicatricial alopecia follicles due to its altered expression in diseased conditions.

This study found that a genetic deletion causing truncated desmoglein 3 protein in mice led to severe pathologies, including cyclic hair loss and immunodeficiency, suggesting possible implications for human desmosome-related diseases.

This study identified FP-1 as a highly specific extracellular matrix protein in follicular papilla cells, which may play a role in hair growth regulation during specific hair cycle phases.

This study found that both androgenetic alopecia and alopecia areata showed significantly increased DKK-1 expression, potentially implicating it in the pathogenesis and as a treatment target for these conditions.

This study found distinct differences in UEA I glycoprotein binding on follicular keratinocytes between anagen and telogen hair follicles, with staining associated with follicle length and regrowth.

In this study, Flii overexpression in mice enhanced fingertip regeneration and nail formation after both distal and proximal amputations, suggesting a role in digit and hair follicle regeneration possibly involving Wnt signaling.
