This study demonstrated that mice lacking skin-specific RXRalpha expression developed hair follicle degeneration and alopecia, indicating the importance of RXRalpha/VDR heterodimers in maintaining hair follicle homeostasis.

This study found that the small signaling peptide RALF22 plays a key role in root hair growth response to volatile compounds emitted by Penicillium aurantiogriseum through ethylene, auxin, and photosynthesis signaling in Arabidopsis.

This paper highlights advances in Developmental Dynamics, noting how epoa-deficient zebrafish can model Diamond-Blackfan anemia like disorders for drug screening, Alx4 mouse models offer insights into craniofacial development, and mTORC1 signaling is crucial for retinal development.

This review discusses the biochemical properties and clinical significance of 5 alpha-reductase isozymes and reports no new clinical results.

This promotional text about Alpha Xtra Boost does not report any new research findings or clinical results.

This study in Arabidopsis thaliana found that exposure to volatile compounds from Penicillium aurantiogriseum promotes root hair growth through signaling involving RALF22, ethylene, auxin, and photosynthesis, and that RALF22 plays a crucial role in the plants' response to these compounds.

This study reported that after 7.5 months of treatment, topical Alfatradiol significantly increased anagen hair rates in women and men with androgenetic alopecia, with minimal side effects.

The trial is ongoing, but researchers are evaluating the efficacy and safety of REZPEG, a potential new therapy for severe alopecia areata, which selectively expands regulatory T cells.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

In this study, researchers found that shorter CA repeats in the ERbeta gene are correlated with PSA expression, and PSA immunoexpression is associated with increased disease-free survival in breast cancer.

This study found that DEFB1 polymorphisms, specifically the rs1800972 CG and GG genotypes, may predict susceptibility to and severity of alopecia areata.

This study found that Egyptian women with frontal fibrosing alopecia had lower serum PPARγ levels and a higher occurrence of PPARG gene polymorphism compared to healthy controls, suggesting a potential role for PPARγ in the condition's development.

The study's findings on omega-6 and hair loss are unreliable.

This review evaluates the role of the nuclear receptor PPAR- in skin diseases, highlighting its regulation of inflammation, lipid metabolism, and immune response, and suggests that PPAR-agonists could be promising therapies for conditions like psoriasis and atopic dermatitis.

This study characterized the SARM PF-05314882, finding it demonstrates anabolic activity in rats with minimal effects on the prostate, seminal vesicles, and luteinizing hormone levels.

This study suggested that electron spin resonance techniques can potentially measure gamma ray exposure in human hair samples, though variability and time sensitivity pose challenges for accurate dose estimation.

This study found that individuals with alopecia areata had significantly higher serum levels of retinol-binding protein 4 and increased IgG immunoreactivity against it, suggesting a role in the disease's pathogenesis.

In this study, a novel compound named AH-001 demonstrated effective androgen receptor protein degradation, reducing hair loss progression in a mouse model of androgenetic alopecia, with minimal systemic exposure and side effects, suggesting potential for safer treatment.

Gene variation affects prostate issues and hair loss.

This study found that estrogen affected cell behaviors differently in a scratch-wound assay, increasing VEGF secretion in follicular dermal papilla cells but decreasing it in wounded dermal sheath cells.

This study found that LepRb neurons in the brain are important targets for androgen action and influence sex-specific differences in reproductive and metabolic regulation, implicating them in conditions such as polycystic ovary syndrome.

This case-control study found that men with earlier onset androgenetic alopecia, particularly frontal balding, may have an increased risk of prostate cancer in a multiethnic veterans cohort.

In this study, the researchers explored how the loss of structural integrity in hair follicles due to reduced α-SMA expression in the vertex area may contribute to androgenetic alopecia.

This study found that supplementing with 1.5% α-ketoglutaric acid significantly improved the performance, hair follicle density, and antioxidant capacity in Rex rabbits, potentially by enhancing the Wnt signaling pathway and reducing amino acid catabolism.

This study found that a specific variant in hair keratin was present mainly in Caucasian samples, with few exceptions showing likely Caucasian admixture.

This chapter reviews recent findings on androgen receptor function, structure, and interactions, highlighting post-translational modifications and mutations related to prostate cancer, but reports no new experimental results.

This study found that RXR and RAR proteins were detectable in normal human skin, suggesting they may play a role in epidermal cell differentiation and hair and gland physiology.

In this study, thalamic GABAA receptor α4 subunit levels were regulated after acute and chronic ethanol exposure, with temporal expression changes affected by phosphorylation state and neuroactive steroids.

Retinoic acid receptors are important for hair follicle development.

This study demonstrated that an AR-EGFP transgene can restore AR function and fertility in Sertoli cell-specific AR knockout mice, highlighting its potential use in understanding androgen receptor functions.
