20 / 1000+ resultsresearch Cytoplasmic Free Calcium Distributions During the Development of Root Hairs of Arabidopsis Thaliana
This study observed that while calcium influx does not initiate root hairs in Arabidopsis thaliana, it may be crucial for sustaining their elongation through elevated calcium levels at the root hair tip.
research Root Hair Growth in Arabidopsis Thaliana Is Directed by Calcium and an Endogenous Polarity
This study found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.
research The Structure of Human Trichohyalin: Potential Multiple Roles as a Functional EF-Hand-Like Calcium-Binding Protein, a Cornified Cell Envelope Precursor, and an Intermediate Filament-Associated (Cross-Linking) Protein
This study suggests that human trichohyalin may function as a flexible rod linking keratin intermediate filaments and as a scaffold protein in hair follicle and epidermis cell envelopes.
research Arabidopsis CNGC14 Mediates Calcium Influx Required for Tip Growth in Root Hairs
This study concluded that CNGC14 is a calcium-permeable channel crucial for polarized tip growth in Arabidopsis root hairs, but other channels may also influence the observed calcium influx.
research Vitamin D And Calcium Regulation Of Epidermal Wound Healing
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.
research Expression of Calcium-Binding S100 Proteins A4 and A6 in Regions of the Epithelial Sac Associated with the Onset of Hair Follicle Regeneration
This study suggests that S100A4 and S100A6 proteins may play key roles in activating stem cells for hair follicle regeneration in mice.
research Sodium Chloride Reduces Growth and Cytosolic Calcium, But Does Not Affect Cytosolic pH, in Root Hairs of Arabidopsis Thaliana L.
This study found that salinity stress in Arabidopsis thaliana root hairs may inhibit hair extension through changes in the tip-focused Ca(2+) gradient, while cytosolic pH remains unaffected.
research Multiple Cyclic Nucleotide-Gated Channels Coordinate Calcium Oscillations and Polar Growth of Root Hairs
This study found that CNGC 6, CNGC 9, and CNGC 14 are crucial for maintaining calcium oscillations necessary for normal root hair growth in plants, with mutations leading to defects like swelling and bursting.
research Light Sheet Fluorescence Microscopy Quantifies Calcium Oscillations in Root Hairs of Arabidopsis Thaliana
This study used light sheet fluorescence microscopy to successfully image and analyze calcium oscillations in the root hairs of Arabidopsis thaliana, finding that these oscillations correlate with the root hair growth rate and that auxin affects these properties.
research The Lanceolate Hair Rat Phenotype Results from a Missense Mutation in a Calcium Coordinating Site of the Desmoglein 4 Gene
This study identified a missense mutation in the rat Desmoglein 4 gene, causing abnormal hair shaft development in lanceolate hair mutant rats by disrupting a critical calcium binding site.
research Overexpression of the Calcium Sensing Receptor Accelerates Epidermal Differentiation and Permeability Barrier Formation In Vivo
This study found that overexpression of the calcium sensing receptor in transgenic mice accelerates epidermal differentiation and hair growth, suggesting its role in enhancing calcium signaling and interaction with other pathways.
research Manganese-Doped Calcium Silicate Nanowire Composite Hydrogels for Melanoma Treatment and Wound Healing
This study explored the use of manganese-doped calcium silicate nanowire-incorporated alginate hydrogels (MCSA hydrogels) for treating melanoma and promoting wound healing, finding that these hydrogels effectively ablate melanoma under near-infrared irradiation and enhance vascular endothelial cell activity for tissue regeneration.
research Ultrastructural Localization of S100A3, a Cysteine-Rich, Calcium Binding Protein, in Human Scalp Hair Shafts Revealed by Rapid-Freezing Immunocytochemistry
In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.
research Gene Expression of Mouse S100A3, a Cysteine-Rich Calcium-Binding Protein, in Developing Hair Follicle
This study found that the S100A3 gene is exclusively expressed in hair follicle cells differentiating into hair shaft components in mice, suggesting its important role in hair formation.
research Skin Regeneration-Related Mechanisms of Calcium Hydroxylapatite: A Systematic Review
This review found limited but suggestive evidence that Calcium Hydroxylapatite may promote skin regeneration through increased collagen production, cell proliferation, and angiogenesis, although most studies had methodological limitations.
research Proliferation and Differentiation of Cultured Human Keratinocytes Is Modulated by 1,25-Dihydroxyvitamin D3 and Synthetic Vitamin D3 Analogues in a Cell Density-, Calcium-, and Serum-Dependent Manner
This study found that human keratinocytes' sensitivity and response to vitamin D3 analogues vary based on cell density, serum availability, and calcium concentration.
research Evidence for Various Calcium Sites in Human Hair Shaft Revealed by Sub-Micrometer X-Ray Fluorescence
This study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.
research Androgens Induce Nongenomic Stimulation of Colonic Contractile Activity Through Induction of Calcium Sensitization and Phosphorylation of LC20 and CPI-17
This study identified that androgens increase calcium sensitization in mouse colonic smooth muscle by activating the Rho/Rho kinase pathway, highlighting its role in modulating muscle contractility.
research Combined Deletion of the Vitamin D Receptor and Calcium-Sensing Receptor Delays Wound Re-Epithelialization
In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.
research Minoxidil-Induced Hypertrichosis: Treatment with Calcium Thioglycolate Depilatory
This report notes that five women experiencing hypertrichosis as a side effect of minoxidil had successful hair removal using a calcium thioglycolate depilatory agent.
