The study found that severe insulin resistance and premature diabetes are common in patients with PCNT genetic defects, primarily affecting those over four years old, while not impacting early insulin signaling in adipocytes.

This review examines physical methods like electron paramagnetic resonance spectroscopy, Raman spectroscopy, and differential scanning calorimetry, highlighting their complementary capabilities in analyzing biomolecular structures and mycobacterial interactions with reactive oxygen species and antioxidants.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.

This study found that GTx-024 significantly increased total lean body mass and improved physical function in healthy elderly men and postmenopausal women, suggesting potential use for muscle wasting conditions.

This study observed that topical application of palmitate or oleate accelerated the onset of the hair growth phase in mice, whereas glycolysis end product lactate delayed it, suggesting metabolic regulation as a promising approach for influencing hair growth.

This study found that topical rebamipide, originally a gastric ulcer medication, can activate hair follicle stem cells and promote hair regeneration by modulating dermal adipocyte metabolism, with potential targeting of the prostaglandin E receptor EP4.

This study reviews iron metabolism in the skin, highlighting how differentially expressed genes regulate iron recycling in the epidermis, and discusses changes in iron metabolism related to skin diseases.

This article provides a critical overview of recent discoveries in the genetics and molecular processes involved in androgenetic alopecia, focusing on its polygenic basis and DHT dependency, but reports no new clinical results.

This study identified 374 eQTLs in scalp hair follicles associated with genes involved in metabolic, mitotic, immune processes, and responses to steroid hormones, contributing insights into genetic variation and hair traits.

This study suggests that women with polycystic ovary syndrome may have a distinct metabolomic profile, differing in levels of amino acids, organic acids, and lipids compared to controls.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

This review assessed experimental studies on herbs used for alopecia, identifying potential mechanisms involving hair cycle management and keratinocyte processes, but highlighted a need for improved evidence on quality control and toxicity of these herbal treatments.

This review suggests that the inner root sheath of human hair follicles may have broader regulatory roles beyond structural support, potentially impacting processes like folliculogenesis, anagen phase regulation, and immunomodulation.

This case study reported that absence of alopecia does not reliably predict responsiveness to vitamin D treatment in Vitamin D-dependent rickets type II, as demonstrated by a patient with normal hair growth who showed extreme resistance.

This article reviews common hair growth abnormalities in children, emphasizing the importance of distinguishing normal development from potential signs of metabolic disorders and indicates no new clinical results.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.
