Mass Spectrometry-Based Proteomics Analysis Unveils PTPRS Inhibits Proliferation and Inflammatory Response of Keratinocytes in Psoriasis. Inflammation 2024:10.1007/s10753-024-02044-z. [PMID: 38739342 DOI: 10.1007/s10753-024-02044-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Revised: 04/25/2024] [Accepted: 05/02/2024] [Indexed: 05/14/2024]
Abstract
In this study, we used data-independent acquisition-mass spectrometry (DIA-MS) to analyze the serum proteome in psoriasis vulgaris (PsO). The serum proteomes of seven healthy controls and eight patients with PsO were analyzed using DIA-MS. Weighted gene co-expression network analysis was used to identify differentially expressed proteins (DEPs) that were closely related to PsO. Hub proteins of PsO were also identified. The Proteomics Drug Atlas 2023 was used to predict candidate hub protein drugs. To confirm the expression of the candidate factor, protein tyrosine phosphatase receptor S (PTPRS), in psoriatic lesions and the psoriatic keratinocyte model, immunohistochemical staining, quantitative real-time polymerase chain reaction, and western blotting were performed. A total of 129 DEPs were found to be closely related to PsO. The hub proteins for PsO were PVRL1, FGFR1, PTPRS, CDH2, CDH1, MCAM, and THY1. Five candidate hub protein drugs were identified: encorafenib, leupeptin, fedratinib, UNC 0631, and SCH 530348. PTPRS was identified as a common pharmacological target for these five drugs. PTPRS knockdown in keratinocytes promoted the proliferation and expression of IL-1α, IL-1β, IL-23A, TNF-α, MMP9, CXCL8, and S100A9. PTPRS expression was decreased in PsO, and PTPRS negatively regulated PsO. PTPRS may be involved in PsO pathogenesis through the inhibition of keratinocyte proliferation and inflammatory responses and is a potential treatment target for PsO.

Abstract
Immunologically targeted therapies have revolutionized the treatment of inflammatory dermatoses, including atopic dermatitis and psoriasis. Although immunologic biomarkers hold great promise for personalized classification of skin disease and tailored therapy selection, there are no approved or widely used approaches for this in dermatology. This review summarizes the translational immunologic approaches to measuring treatment-relevant biomarkers in inflammatory skin conditions. Tape strip profiling, microneedle-based biomarker patches, molecular profiling from epidermal curettage, RNA in situ hybridization tissue staining, and single-cell RNA sequencing have been described. We discuss the advantages and limitations of each and open questions for the future of personalized medicine in inflammatory skin disease.

[DOI: 10.26442/20751753.2022.8.201853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/06/2022] Open
Abstract
Background. Psoriasis (skin lesions and psoriatic arthritis PA) is a chronic inflammatory autoimmune disease that can be triggered by excessive activation of endosomal toll-like receptors (TLRs), mainly TLR9. Elevated TLR9 levels are observed in both PA and psoriasis. Therefore, studying the expression pattern of the TLR9 gene may help select therapies for patients with PA and psoriasis.
Aim. To study the expression pattern of the TLR9 gene in blood mononuclear cells of PA and psoriasis patients without joint involvement for possible use in the transition to targeted therapy.
Materials and methods. Mononuclear cells were isolated from the peripheral blood of 31 patients with psoriasis vulgaris without joint involvement, 45 patients with PA, and 20 healthy volunteers. TLR9 gene expression was analyzed by real-time polymerase chain reaction.
Results. A comparison of expression levels in PA patients and healthy volunteers showed that the expression level of TLR9 in PA patients was 591 times higher than that in healthy volunteers. The expression level of TLR9 in psoriasis patients without joint involvement was also significantly (423-fold) higher than that in healthy subjects.
Conclusion. TLR9 gene expression in mononuclear cells of psoriasis patients with severe skin lesions is similar to that in PA patients. High levels of TLR9 gene expression may be a marker of possible joint involvement in patients with psoriasis and indicate the need to reconsider the therapeutic approach to a particular patient.

Nucleic Acids Res 2022; 51:D1263-D1275. [PMID: 36243960 PMCID: PMC9825618 DOI: 10.1093/nar/gkac812] [Citation(s) in RCA: 27] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 08/22/2022] [Accepted: 10/11/2022] [Indexed: 01/30/2023] Open
Abstract
Widespread drug resistance has become the key issue in global healthcare. Extensive efforts have been made to reveal not only diverse diseases experiencing drug resistance, but also the six distinct types of molecular mechanisms underlying this resistance. A database that describes a comprehensive list of diseases with drug resistance (not just cancers/infections) and all types of resistance mechanisms is now urgently needed. However, no such database has been available to date. In this study, a comprehensive database describing drug resistance information named 'DRESIS' was therefore developed. It was introduced to (i) systematically provide, for the first time, all existing types of molecular mechanisms underlying drug resistance, (ii) extensively cover the widest range of diseases among all existing databases and (iii) explicitly describe the clinically/experimentally verified resistance data for the largest number of drugs. Since drug resistance has become an ever-increasing clinical issue, DRESIS is expected to have great implications for future new drug discovery and clinical treatment optimization. It is now publicly accessible without any login requirement at: https://idrblab.org/dresis/.
