research Evidence for 1,25-Dihydroxyvitamin D3-independent Transactivation by the Vitamin D Receptor
This study found that vitamin D receptor activation in primary keratinocytes can occur independently of the 1,25-dihydroxyvitamin D3 ligand, likely through interaction with retinoid X receptors.
research Rejection Sensitivity and Problematic Internet Use Among Medical Students: A Moderated Mediation Model Involving Loneliness and Self-Control
In a study of 435 undergraduate medical students, researchers found that rejection sensitivity was linked to increased loneliness and problematic internet use, with loneliness mediating this relationship and self-control moderating its impact, highlighting pathways and conditions that could inform interventions.
research Expression Level of Prostaglandin D2 Receptor 2 Regulates Hair Regression
This study suggests that the expression of the DP2 receptor is higher in balding scalp cells and that its knockdown could inhibit the transition to the catagen phase in cultured human hair follicles, potentially counteracting hair growth inhibition associated with male pattern baldness.
research Inhibiting Biosynthesis and/or Metabolism of Progestins in the Ventral Tegmental Area Attenuates Lordosis of Rats in Behavioural Oestrus
This study suggests that both the central biosynthesis and metabolism of progesterone to 3α,5α‐THP in the ventral tegmental area are crucial for facilitating lordosis in female rats.
research Physiopathological role of the enzymatic complex 5α-reductase and 3α/β-hydroxysteroid oxidoreductase in the generation of progesterone and testosterone neuroactive metabolites
This study suggests that synthetic steroid analogues or 5α-reductase modulation could be potential therapeutic strategies for nervous system disorders, but further research on their effects is necessary.
research Transgenic mice display hair loss and regrowth overexpressing mutant Hr gene
This study found that in transgenic mice overexpressing a mutant hairless gene, changes in its expression affected hair loss and regrowth, implicating the gene's role in hair follicle biology.
research Cellular plasticity in reprogramming, rejuvenation and tumorigenesis: a pioneer TF perspective
This review highlights the potential of in vivo reprogramming using OSKM transcription factors for developing rejuvenating and regenerative strategies, while noting the associated risk of tumorigenicity and discussing how improved understanding could lead to safer applications.
research Safety of Whole-Body Abrogation of the TRF1 Shelterin Protein in Wild-Type and Cancer-Prone Mouse Models
In this study, Trf1 genetic deletion in mice, including those with cancer-prone mutations, was shown to not affect overall viability and cause only mild effects, while being necessary for tumor formation, suggesting a potential therapeutic window for Trf1 as an anti-cancer target.
research Intratumoral De Novo Steroid Synthesis Activates Androgen Receptor in Castration-Resistant Prostate Cancer and Is Upregulated by Treatment with CYP17A1 Inhibitors
This study found that castration-resistant prostate cancers resistant to CYP17A1 inhibitors may still depend on steroids and could respond to therapies targeting de novo intratumoral steroid synthesis.
research Aromatase-independent testosterone conversion into estrogenic steroids is inhibited by a 5α-reductase inhibitor
This study found that testosterone is converted to estrogenic steroids in vitro without aromatase involvement, suggesting that combining 5α-reductase and aromatase inhibitors might reduce estrogenic steroids more completely in vivo.
research Post-transcriptional Regulation of Keratinocyte Progenitor Cell Expansion, Differentiation and Hair Follicle Regression by miR-22
This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.
research Neurosteroidogenesis Is Required for the Physiological Response to Stress: Role of Neurosteroid-Sensitive GABAAReceptors
This study demonstrated that stress-derived neurosteroid THDOC shifts from inhibiting to activating the HPA axis under stress, presenting potential therapeutic targets for stress-related disorders.
research p75 Neurotrophin Receptor Antagonist Retards Apoptosis-driven Hair Follicle Involution (Catagen)
In this study, a synthetic antagonist of the p75 neurotrophin receptor was found to significantly inhibit hair follicle regression in murine skin cultures, suggesting a potential role in treating hair disorders characterized by premature catagen entry.
research Hairless and the polyamine putrescine form a negative regulatory loop in the epidermis
This study found that Hairless (HR) and putrescine form a negative regulatory network that impacts epidermal homeostasis and hair follicle cycling, linked to the MYC superfamily's regulation of ODC expression.
