This study suggests that vitamin D and calcium signaling play a crucial role in wound healing by regulating stem cell activation through enhanced β-catenin transcriptional activity in mice.

This study used Cisd2 knockout mice models and found that these mice display premature aging characteristics and an increase in dysfunctional neutrophils, suggesting Cisd2's role in calcium homeostasis and neutrophil function via interactions with Calnexin and SERCA.

This review evaluates controlled studies on Platelet-Rich Plasma for androgenetic alopecia treatment, reporting positive effects on hair growth and density but highlighting the need for standardized protocols.

This study suggests that TIP39 and its receptor PTH2R, identified in human epidermis, may play a role in keratinocyte function and influence skin differentiation.

This review discusses the regulation of involucrin gene expression, focusing on transcription factors and signaling pathways, and reports no new experimental findings.

The researchers reported that both estrogen receptors ERα and ERβ are expressed in human testis, and identified two novel genes, Aven and Regucalcin, linked to estrogen and androgen regulation, which may be crucial for spermatogenesis.

The researchers reported that VEGF increases vascular permeability in mesenteric microvessels of anaesthetized frogs through specific cellular pathways involving tyrosine autophosphorylation and PLC activation.

This study found that humanized mouse models expressing mutated or reduced levels of the vitamin D receptor were able to maintain normal mineral homeostasis and prevent typical symptoms of vitamin D resistance.

The conclusion is that effectively treating hair disorders is difficult due to the complex factors affecting hair growth and more research is needed to improve treatments.

In this study, researchers found that a positive feedback loop involving Ca 2+ and RHD2 NADPH oxidase-derived ROS helps maintain growth sites, crucial for root hair development and cell shape in Arabidopsis thaliana.

This study found that Epiprofin acts as a negative regulator of parathyroid hormone transcription, with potential implications for controlling PTH production in hyperparathyroidism.

This study found that a positive feedback loop involving RHD2, reactive oxygen species, and calcium ions helps maintain root hair growth sites and influences cell shape in Arabidopsis thaliana.

This study reports that the loss of the protein Memo in mice leads to a reduced lifespan and suggests that Memo is a key regulator of FGFR signaling and vitamin D production.

This study suggests that frontal fibrosing alopecia is a highly inflammatory disease involving TH1 and JAK-STAT pathways, without reduced hair keratins, highlighting JAK-STAT signaling as a potential therapeutic target.

This study investigated protein expression changes during mouse hair follicle cycles and suggested their involvement in biological networks, potentially identifying targets for hair disease therapy.

NFATc1 is crucial for keeping hair follicle stem cells inactive.

This study found that gene expression changes in hair bulb cells are linked to graying hair, affecting processes like melanogenesis and cell-cell interaction.

This review discusses the molecular role of the vitamin D receptor in regulating various biological actions such as bone mineralization and reports no new clinical results, highlighting the complexity of vitamin D's function in multiple tissues.

This study found that many participants with hair loss, or Khalitya, exhibited dietary incompatibilities and low calcium levels, aligning Ayurvedic concepts with modern dietary risk factors.

In this observational study, researchers found that 55% of participants with hair loss known as Khalitya had serum calcium deficiency, which aligns with both Ayurvedic and modern perspectives linking poor nutrition to hair disorder, highlighting the importance of dietary regulation and stress management.

This paper discusses how NADPH oxidase and phospholipase D are important for root hair growth, with reactive oxygen species from NADPH oxidase activating calcium ion channels in root hairs.
