Proteomic Analysis of Skin Punch Biopsies from a Parkinson's Disease Patient Cohort: A PPMI Pilot Study

ABSTRACT: A human skin proteome MS spectral library, generated from tissue punch biopsies of the C8 paravertebral region in Parkinson's disease patients. This data and associated protocol (https://www.protocols.io/view/proteomics-sample-preparation-of-human-skin-punch-14egn9e46l5d/v1) were generated as part of a pilot study in collaboration with the Michael J. Fox Foundation. The biospecimens were obtained from the Parkinson’s Progression Marker Initiative (PPMI) (RRID:SCR_006431). For up-to-date information on the study, visit www.ppmi-info.org.

Platelet mRNA in response to antiplatelet therapy exposure

Project description:The purpose of this study was to identify changes in platelet mRNA that result from exposure to antiplatelet therapy. A total of 84 healthy volunteers were recruited into a longitudinal study of various antiplatelet exposures with 58 completing all study visits. This was a 5 visit study where each visit was separated by ~ 4 weeks. At each Visit purified platelets using a CD45 negative selection protocol was performed in addition to platelet function testing using light transmittance aggregometry (ADP, EPI, and Collagen) and PFA100 (Col/EPI). After the baseline visit (V1), participants were randomized to receive 81mg/day or 325mg/day aspirin x 4 weeks followed by Visit 2. Participants then crossed over to the alternative dose of aspirin for 4 weeks followed by Visit 3. Between Visits 3 and 4 participants washed out their aspirin for 4 weeks. The final exposure was ticagrelor 90mg twice daily x 4 weeks until Visit 5.

Bulk-cell RNA-seq analysis of early cutaneous wound healing in mouse

Project description:To study early-onset gene expression changes in cutaneous wound healing, 3 mm wounds were induced into the back skin of female wildtype C57BL/6 mice using a biopsy punch. Mice were sacrificed 2h, 6h or 24h post wound induction (PWI) and 1 - 1.5 mm of skin lining the wound edge was isolated and sequenced. The skin from the initial punch biopsy (0h PWI) was preserved and taken as a control sample to identify differentially expressed genes.

Differences in cell subsets between sun-exposed and unexposed skin: preliminary single-cell sequencing and biological analysis from a single case

Project description:The microcosmic and specific changes of human photoaging skin without chronologic aging is still unclear and rare-ly analyzed. We aimed to assess biological processes of the cell-subgroups alteration and mechanisms of skin pho-toaging using single cell sequencing and biological analysis were used between sun-exposed forearm skin and un-exposed buttock skin in same individual via skin punch biopsy.

circRNA expression in cutaneous squamous cell carcinoma (cSCC)

Project description:Punch biopsies from patients with cSCC (n=3) and non-lesional skin (n=3) were included in the study. Microarray based circRNA expression profiles were acquired using Arraystar circRNA Arrays V. 2.0 screening for 13.617 distinct human circRNA candidates. We identified circRNAs differentially expressed in cSCC compared to non-lesional skin (control).

Allergen Challenge for Evoked Phenotypes in Asthma (the ACE Study)

Project description:This protocol outlines a single-site mechanistic study aiming to investigate long RNAs differentially expressed in the airway epithelium of asthma patients both at baseline and in response to segmental airway allergen challenges. Over approximately 14 days, the study spanned three visits: Visit 1: Comprehensive characterization of participants, encompassing lung function testing, methacholine challenge testing, and allergen skin prick testing. Visit 2: Participants underwent bronchoscopy wherein three procedures were performed a. Epithelial brushings were performed in a segmental airway (baseline sample) b. Diluent (inactive control) was instilled into another segmental airway c. A small dose of allergen was administered into a third segmental airway using standardized cat or dust mite allergen extracts. Visit 3 (24 hours or 7 days post Visit 2): Another bronchoscopy was carried out to collect epithelial brushings in the diluent challenged and allergen challenged segments The collected epithelial brush samples underwent analysis for mRNA expression in the epithelial brushings. The study successfully incorporated a total of 23 subjects, which included 18 asthmatics (with stable or well-controlled conditions), 2 allergic non-asthmatics, and 3 non-allergic non-asthmatics.
