In this study, oral contraceptive use in women with PCOS increased the expression of certain inflammatory gene markers, which were positively associated with metabolic abnormalities.

This study found that the loss of Smad4 in keratinocytes reduces Dsg4 expression via disrupted BMP signaling, contributing to hair follicle degeneration and alopecia.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

This study found that angiogenin is expressed in human dermal papilla cells, where it might stimulate hair growth by promoting cell proliferation and local skin angiogenesis.

The researchers reported that introduction of SOX9 in ischemic heart tissues is linked to cardiac fibrosis, marking it as a potential target for future therapeutic strategies.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

This study observed specific expression patterns of three zebrafish estrogen receptor genes during development, highlighting robust co-expression of esr2a and esr2b in primary neuromasts, branchial arches, and other tissues.

This study found that Eda and activin A regulate Foxi3 expression, which may contribute to the development of hypohidrotic ectodermal dysplasia by affecting Foxi3 activity in ectodermal appendages like hair and teeth.

This study found that conditioned media from epidermal progenitor cells improved skin aging signs in a clinical trial and protected fibroblasts from oxidative stress in vitro.

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 observed that downregulation of laminin-511 plays an important role in hair regression during the catagen stage in mice.

This study found that activin B promotes the initiation and development of hair follicles in both cultured and neonatal mouse skin models.

This review discusses advancements in understanding hair cycle and inflammatory alopecias, proposing a standard classification and tiered treatment recommendations, but reports no clinical results.

This review discusses the conditions, genetic factors, and treatment options related to polycystic ovary syndrome, but reports no new clinical findings, emphasizing the need for future research.

This study found that the IGF2 gene Apa1 A820G polymorphism is associated with an increased risk of developing PCOS in the studied population.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

This review discusses the various stem cell populations associated with hair follicles and their potential in regenerative medicine, highlighting differences between murine and human hair follicles but reports no new clinical results.

This hypothesis paper suggests that PCOS may result from genetically determined ovarian hypersecretion of androgens, influencing hormone regulation and insulin resistance, with obesity further affecting its severity; no new clinical results are reported.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This study found that stabilized beta-catenin is crucial for activating stem cell transition from quiescence to proliferation in hair follicles by influencing gene expression within the stem cell niche.

This abstract reviews the characteristics and health risks associated with polycystic ovary syndrome and does not report new findings, highlighting the syndrome's multifactorial nature.

This study found that altering cell culture conditions to form three-dimensional papilla spheroids can restore the ability of human dermal papilla cells to induce hair growth in adult skin.

This review discusses the hypothesis that polycystic ovary syndrome may originate in fetal life due to prenatal androgen exposure, but reports no new clinical results.

This study identified ectodin as a novel BMP inhibitor that modulates BMP signaling in ectodermal development by interacting with SHH and FGF pathways.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This study found that overexpression of activin in transgenic mice led to enhanced granulation tissue formation after skin injury due to changes in keratinocyte proliferation and differentiation.
