This study found that while rat models treated with letrozole and dihydrotestosterone exhibit altered sterol, leukotriene, and steroid hormone profiles similar to human PCOS, significant differences remain.

This randomized control trial reported that mesenchymal stem cell-derived exosomes significantly increased hair density and thickness in patients with androgenic alopecia, with a mean increase of 35 hairs/cm² over 12 weeks compared to the placebo group, which showed minimal hair density changes.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This study constructed a comprehensive atlas of prenatal human skin, revealing that innate immune cells, such as macrophages, play a crucial role in skin morphogenesis by interacting with non-immune cells, influencing hair follicle formation and angiogenesis beyond their traditional immune functions.

This study observed a 30.4% decrease in dermatology outpatient visits during the COVID-19 pandemic, with a shift in patient demographics and an increased frequency of psoriasis, bullous diseases, and melanoma diagnoses, while conditions like acne and xerosis cutis were less frequent.

This study found that VE-cadherin and Alk1, traditionally linked to vascular functions, also play crucial roles in maintaining nerve homeostasis in mice during hair growth cycles by modulating certain cell populations.

This study found that intracrine androgen signaling, mediated by steroid 5α-reductase, is essential for optimal decidualization and vascular development in the endometrium during pregnancy, indicating potential targets for improving age-related fertility issues.

In June 2019, the stem cell research field saw major progress, including new clinical trials, FDA approvals, and industry collaborations.

This symposium reviewed various topics in stem cell research related to skin biology, including mechanisms of skin regeneration, tumorigenesis, and pathways influencing melanoma stem cell behavior, but it reported no new clinical results.

This study reported that high cholesterol levels were linked to increased prostate cancer risk, while selenium supplementation affected gene expression, suggesting nutritional and clinical factors might influence prostate cancer risk and biology.

In this study, eight patients with hereditary vitamin D-resistant rickets who share a specific VDR mutation showed improved clinical symptoms except alopecia after up to 11 years of treatment.

In this study, a novel VDR gene mutation was identified in a child with HVDRR, and the researchers observed that high-dose intravenous calcium therapy led to significant and sustained improvement in rickets symptoms.

This study reported a case of hereditary vitamin D–resistant rickets caused by a single heterozygous missense mutation in the VDR gene, showing dominant-negative effects and reduced response to 1,25-dihydroxyvitamin D3.

This study analyzed post-marketing data from the U.S. FDA Adverse Event Reporting System and identified both known and new safety concerns for Avacopan, an anti-neutrophil cytoplasmic antibodies-associated vasculitis treatment, emphasizing the need for monitoring during early treatment stages.

This study identified a novel I268T mutation in the vitamin D receptor that reduces its function, contributing to hereditary vitamin D-resistant rickets, and found that a potent vitamin D analog could improve receptor function.

This study found that arginine vasotocin is evolutionarily conserved across diverse taxa and may play roles in neuroendocrine, immune, and stress signaling, with potential antimicrobial applications.

In this study, a Chinese Han family with hereditary vitamin D-resistant rickets was found to have a homozygous missense mutation in the VDR gene, and the affected individual uniquely responded well to treatment with oral calcium and low-dose calcitriol.

This study describes a patient with hereditary vitamin D resistant rickets (HVDRR) who, despite having a truncated vitamin D receptor, did not exhibit typical hair or skin abnormalities, suggesting possible compensation via interactions with other proteins.

This study found that manipulating AKR1D1 expression in human liver cells effectively regulates glucocorticoid clearance and receptor activation, highlighting its role in liver-specific steroid hormone regulation.

This study found that most pathogenic HR mutants associated with atrichia with papular lesions had abolished corepressor activity due to defective interactions with histone deacetylases.

In this retrospective study of eight Saudi children with hereditary vitamin D resistant rickets, researchers observed that adjunctive cinacalcet appeared safe and showed initial promise in improving serum PTH levels, though further investigation is needed to confirm its efficacy.

This study found that a novel R343H mutation in the vitamin D receptor gene impairs its transcription activity, contributing to hereditary vitamin D-resistant rickets and alopecia in the affected family.

This review discusses the acyl-CoA synthetase very-long-chain (ACSVL) enzyme family, including its biochemical characteristics, tissue expression, and involvement in lipid metabolism, but presents no new experimental results.

In this case study, a girl with hereditary vitamin D resistant rickets had a novel mutation in the VDR gene that affected hair cycling without causing total alopecia, suggesting ligand-independent VDR function in hair cycling.

This article discusses the development and clinical progress of PROTAC technology, particularly focusing on the New Drug Application for vepdegestrant, an estrogen receptor-targeting PROTAC, marking significant advancements in targeted protein degradation therapies.

This case report details two consanguineous patients with cerebral autosomal recessive arteriopathy, both having the same HTRA1 gene mutation, but exhibiting different clinical presentations, including one with epileptic seizures and lobar hemorrhages—previously undocumented in this condition.

This study reports that Abelson Interactor 1 (ABI1) regulates androgen receptor transcription in prostate cancer, identifying it as a potential target for new therapies addressing treatment resistance.

In an outpatient cardiology center, this study found that introducing the AHA/ACC ABI screening protocol significantly increased the frequency of ABI ordering by 31.6% for symptomatic patients.

This study found that in noise-exposed FVB/NJ mice and cell models, ivacaftor reduced oxidative stress and hearing damage by maintaining CFTR function and increasing Nrf2 expression, suggesting its potential for treating noise-induced hearing loss.
