Proteome-wide changes in primary skin keratinocytes exposed to diesel particulate extract – a role for antioxidants in skin health

ABSTRACT: Environmental air pollution such as diesel smoke emission has been shown to have an adverse effect on human skin. Although epidemiological studies showing adverse effects such as oxidative stress-induced aging exists, studies showing the cellular and molecular response to such stress are rare. Using a primary skin keratinocyte model and TMT-based quantitative proteomics strategy, we studied the effects of chronic exposure to diesel particulate matter (DPE) and DPE vapor on the cellular proteome and the ability of a known anti-oxidant Vitamin E in ameliorating such changes. LC-MS3 analysis of DPE and/or its vapor exposed skin keratinocytes resulted in quantification of 4,490 proteins of which 201 and 374 proteins were significantly dysregulated (≥1.5 fold, p-value ≥0.05) in each condition, respectively. We observed distinct molecular alterations in chronic DPE and DPE vapor exposure models. Dysregulation of several cellular processes such as cell cycle and gene regulation, oxidative stress response proteins, skin barrier integrity and skin hydration were observed in both DPE and DPE vapor exposed cells.

<h4>Background</h4>Skin acts as a protective barrier against direct contact with pollutants but inhalation and systemic exposure have indirect effect on keratinocytes. Exposure to diesel exhaust has been linked to increased oxidative stress.<h4>Objective</h4>To investigate global proteomic alterations in diesel particulate extract (DPE)/its vapor exposed skin keratinocytes.<h4>Methods</h4>We employed Tandem Mass Tag (TMT)-based proteomics to study effect of DPE/DPE vapor on primary skin keratino ...[more]

Project description:Cutaneous lupus erythematosus (CLE) is an autoimmune disease that localizes to the skin and is known to contain elevated glycosaminoglycans (GAGs) on Hale’s stain of skin biopsy specimens. Recently, different GAG species have been shown to have distinct effects on the recruitment and activation of immune cells and stimulation of cytokine production (Taylor and Gallo, FASEB, 2006; 20: 9-22). Thus, we speculate that the elevated GAGs observed in CLE play a role in the local inflammatory process that produces skin lesions in these patients. In order to further investigate a molecular basis for the elevated expression of these GAGs in CLE skin lesions, we would like to determine the gene expression profiles of GAG synthesis, degradation, and modifier genes in lesional and non-lesional skin samples from CLE patients and compare to those from healthy controls. A microarray approach will give us a broader understanding of the genetic regulation of the expression of various GAG species in CLE skin. We will then be able to target future quantitative gene expression experiments by real-time RT-PCR to the genes that are shown to be involved in CLE. In order to accomplish our goal, we would like to examine the GAG gene expression profiles of DLE, TLE, and SCLE subtypes due to the differences in CS and HA staining that we found among these subtypes. Since HA and CS are elevated in DLE and HA in TLE, but not in SCLE, the SCLE samples will also serve as an internal control. We would like to examine both lesional and non-lesional skin biopsies to determine if CLE skin prior to developing a lesion is different at the genetic level from healthy control skin and how it changes once a lesion does develop. We will separate the dermis from the epidermis of the skin biopsies and extract RNA just from the dermis to enrich for dermal fibroblast RNA. We aim to submit four patient biopsies per subtype as well as four samples from healthy control skin for comparison. This number is necessary in order to account for the biologic variability among different patients. We would submit more samples per subtype but are limited by availability of patients in clinic. Thus, we will have a total of 28 samples to submit for microarray. This study design will allow us to analyze the GAG gene expression profiles among different CLE subtypes and enable us to identify which GAc
