Ultrastructure of Cells and Microanalysis in Malus domestica Borkh. ‘Szampion’ Fruit in Relation to Varied Calcium Foliar Feeding

open access: yesMolecules, 2020
Calcium is one of the most poorly reutilized nutrients. Its deficiencies cause various physiological disturbances and, consequently, reduce the quantity and quality of yields.

Does Chytridiomycosis Affect Tree Frog Attachment?

open access: yesDiversity, 2021
The pandemic disease chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), is a major threat to amphibian biodiversity. For most species, the exact mechanisms of chytridiomycosis that lead to negative population dynamics remain ...

UV Radiation and Its Relation to DNA Methylation in Epidermal Cells: A Review

open access: yesEpigenomes, 2020
DNA methylation is the most studied epigenetic mark, and it can be altered by environmental factors. Among these factors, ultraviolet radiation (UV) is little explored within this context.

An Anhydrous Sodium Chloride Skin Preservation Model for Studies on Keratinocytes Grafting into the Wounds

open access: yesPharmaceutics, 2021
Background. Human skin is needed for covering large body areas lost by trauma. The shortcomings of contemporary methods of skin storage are limited preservation time and high immunogenicity if allogeneic. Methods.

Keratinocytes mediate innocuous and noxious touch via ATP-P2X4 signaling

open access: yeseLife, 2018
The first point of our body’s contact with tactile stimuli (innocuous and noxious) is the epidermis, the outermost layer of skin that is largely composed of keratinocytes.

A protein phosphatase network controls the temporal and spatial dynamics of differentiation commitment in human epidermis

open access: yeseLife, 2017
Epidermal homeostasis depends on a balance between stem cell renewal and terminal differentiation. The transition between the two cell states, termed commitment, is poorly understood.

Iron Metabolism of the Skin: Recycling versus Release

open access: yesMetabolites, 2023
The skin protects the body against exogenous stressors. Its function is partially achieved by the permanent regeneration of the epidermis, which requires high metabolic activity and the shedding of superficial cells, leading to the loss of metabolites ...

The plant hormone ethylene restricts Arabidopsis growth via the epidermis

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance Ethylene is a gaseous hormone that controls plant life throughout development. Being a simple hydrophobic molecule, it can freely enter cells; therefore, the cell type specificity of its action is challenging.

Keratin 14-dependent disulfides regulate epidermal homeostasis and barrier function via 14-3-3σ and YAP1

open access: yeseLife, 2020
The intermediate filament protein keratin 14 (K14) provides vital structural support in basal keratinocytes of epidermis. Recent studies evidenced a role for K14-dependent disulfide bonding in the organization and dynamics of keratin IFs in skin ...
