Regulation of ERK-MAPK signaling in human epidermis
Jul 25, 2015 · The skin is largely comprised of keratinocytes within the interfollicular epidermis. Over approximately two weeks these cells differentiate and traverse the thickness of the skin.
MAPK Pathway Involved in Epidermal Terminal Differentiation of …
The MAPK signaling pathway has been shown to play critical roles in epidermal differentiation and skin barrier function [20,21,22,23]. The MAPK signaling pathways can integrate and mediate various signals involved in keratinocyte differentiation, including epidermal growth factor receptor (EGFR), integrin and calcium signaling.
MAPK/AP-1 Signaling Pathway Is Involved in the Protection
Introduction: The role of bone marrow mesenchymal stem cells-derived exosomes (BMSCs-exo) in skin photoaging was explored in human dermal fibroblasts (HDFs). The underlying mechanism was further explored. Methods: HDFs were exposed to UVB irradiation to establish the cell photodamage models.
The Complexity of the ERK/MAP-Kinase Pathway and the …
The central role played by the ERK/MAPK pathway downstream of RAS in human neoplasias is best exemplified in the context of melanoma skin cancer. Signaling through the MAPK pathway is crucial for the proliferation of melanocytes, the healthy pigment cells that give rise to melanoma.
Phospholipase Cδ1 regulates p38 MAPK activity and skin barrier ...
Apr 21, 2017 · Immunoblotting and immunohistochemistry revealed that phosphorylated-p38 MAPK was increased in the skin and epidermis of IMQ-treated mice (Figures 6a and b).
Regulation of ERK-MAPK signaling in human epidermis
Jul 25, 2015 · The model demonstrates that the spatial profile of activation for ERK-MAPK signaling components across the epidermis may be maintained in a cell-autonomous fashion by an underlying spatial gradient in calcium signaling.
SIRT1 regulates MAPK pathways in vitiligo skin: insight into the ...
Jan 10, 2014 · MAPK pathways are affected by Resv-induced SIRT1 activation in keratinocytes from perilesional vitiligo skin. In our previous study, we demonstrated that keratinocytes from perilesional vitiligo skin showed signs of oxidative stress and apoptosis.
p38 MAPK Signaling in Pemphigus: Implications for Skin …
Jul 10, 2013 · It has become apparent that p38 MAPK is involved in skin autoimmune diseases such as pemphigus. Nevertheless, its targeting can lead to completely unpredictable outcomes and certain adverse side effects depending on the different cells participating in …
Role of ERK Pathway in the Pathogenesis of Atopic Dermatitis and …
We examined the expression of p-ERK in mouse and human AD skin. We also investigated the effects of the topical application of an ERK inhibitor on the dermatitis score, transepidermal water loss (TEWL), histological change, and expression of …
Cutaneous wound healing through paradoxical MAPK activation …
Aug 1, 2016 · Here we show how the BRAF inhibitor vemurafenib accelerates skin wound healing by inducing the proliferation and migration of human keratinocytes through extracellular signal-regulated kinase...
