Long noncoding RNA MALAT1 in dermatologic disorders: a comprehensive review. Biomark Med 2024; 18:853-867. [PMID: 38982732 PMCID: PMC11497971 DOI: 10.1080/17520363.2024.2369044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 06/11/2024] [Indexed: 07/11/2024] Open
Abstract
Dermatologic disorders, affecting the integumentary system, involve diverse molecular mechanisms such as cell proliferation, apoptosis, inflammation and immune responses. Long noncoding RNAs, particularly Metastasis-Associated Lung Adenocarcinoma Transcript 1 (MALAT1), are crucial regulators of gene expression. MALAT1 influences inflammatory responses, immune cell function and signaling pathways, impacting various physiological and pathological processes, including dermatologic disorders. Dysregulation of MALAT1 is observed in skin conditions like psoriasis, atopic dermatitis and systemic lupus erythematosus. However, its precise role remains unclear. This review consolidates knowledge on MALAT1's impact on skin biology and pathology, emphasizing its potential diagnostic and therapeutic implications in dermatologic conditions.

Abstract
Psoriasis is an incurable skin disease that develops in about two-thirds of patients before the age of 40 and requires lifelong treatment; its pathological mechanisms have not been fully elucidated. The core pathological process of psoriasis is epidermal thickening caused by the excessive proliferation of epidermal keratinocytes, which is similar to the key feature of cancer; the malignant proliferation of cancer cells causes tumor enlargement, suggesting that there is a certain degree of commonality between psoriasis and cancer. This article reviews the pathological mechanisms that are common to psoriasis and cancer, including the interaction between cell proliferation and an abnormal immune microenvironment, metabolic reprogramming, and epigenetic reprogramming. In addition, there are common therapeutic agents and drug targets between psoriasis and cancer. Thus, psoriasis and cancer share a common pathological mechanisms-drug targets-therapeutic agents framework. On this basis, it is proposed that investigating psoriasis from a cancer perspective is beneficial to enriching the research strategies related to psoriasis.

Abstract
BACKGROUND Psoriasis and vitiligo are both chronic, skin-specific diseases classified as autoimmune diseases due to the involvement of several biochemical pathways in their pathogenesis, similar to those altered in other autoimmune diseases. The role of miRNAs in regulating skin autoimmune function has yet to be fully characterized. AIM The aim of this study was to assess the expression profile of a panel of 11 circulating immune-related miRNAs in patients with autoimmune skin diseases, specifically psoriasis and vitiligo, and correlate their expression signature with the clinicopathological features of the diseases. SUBJECTS AND METHODS Relative gene expression quantification for 11 immune-related circulating miRNAs in plasma was done for 300 subjects-100 patients with psoriasis, 100 patients with vitiligo and 100 normal healthy volunteers-followed by different modalities of bioinformatics analysis for the results. RESULTS The expression levels of all the studied immune-related miRNAs were elevated in both autoimmune skin disorders, with much higher levels of expression in psoriasis than in vitiligo patients. There was a significant correlation between most of the studied miRNAs, suggesting shared target genes and/or pathways. Moreover, all the studied miRNAs showed significant results as biomarkers for autoimmune skin disease, with miRNA-145 being the best candidate. Regarding the clinicopathological data, miRNA-7, miRNA-9, miRNA-145, miRNA-148a, and miRNA-148b were positively correlated with age. All the miRNAs were inversely correlated with obesity and disease duration. CONCLUSION This study highlights the critical role of miRNAs in skin-specific autoimmune diseases that proved to be potential biomarkers for autoimmune skin disorders, warranting their exploration as therapeutic targets.

Abstract
Vascular dementia (VaD) is the second most common subtype of dementia, but the precise mechanism underlying VaD is not fully understood. Long non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) can act as a key regulator in physiological and pathological processes, including neurological disorders, but whether it is correlated with VaD has not been elucidated. In this study, we established a mouse model of VaD by the transient bilateral common carotid artery occlusion surgery. As expected, the Morris water maze showed that VaD mice had significant deficits in spatial learning and memory. MALAT1 was elevated in the hippocampus of VaD mice. Additionally, we found that microRNA (miR)-9-3p was downregulated in the VaD hippocampus. By performing a dual-luciferase report assay, we verified the binding relationship between MALAT1 and miR-9-3p. Interestingly, synapse-associated protein-97 (SAP97), a well-known gene related to synaptic functions, was found upregulated in the hippocampus of VaD mice. In vitro experiments performed on hippocampal neurons demonstrated that miR-9-3p negatively regulated SAP97 expression. The downregulation of MALAT1 in hippocampal neurons increased miR-9-3p and reduced SAP97, whereas miR-9-3p inhibition rescued the MALAT1 downregulation-mediated SAP97 reduction. In conclusion, the present study reported the alterations in the expression levels of MALAT1, miR-9-3p, and SAP97 in the hippocampus of VaD mice, suggesting that MALAT1 targets miR-9-3p to upregulate SAP97 in the hippocampus of mice with VaD. This work will be helpful for understanding the molecular mechanisms of VaD.

Abstract
INTRODUCTION Psoriasis is an immune-mediated polygenic inflammatory skin disease, keratinocyte proliferation is an important mechanism. The study investigated the role and regulatory relationship between lncRNA XIST and miR-338-5p in psoriatic patients and cell models. METHODS Serum samples were collected from 55 psoriasis patients. HaCaT was recruited for the cell experiments, and induced by M5 cytokines to mimic psoriasis in vitro. XIST and miR-338-5p levels were detected via qRT-PCR. Cell viability under different treatments was evaluated using CCK-8. ELISA was applied to measure the concentration of inflammatory cytokines. The regulatory relationship was confirmed using luciferase reporter gene assay. RESULTS Serum XIST was elevated in patients with psoriasis, and can distinguish the psoriasis patients from healthy controls according to the ROC curve. High level of XIST was positively correlated with with PASI score and serum TNF-α, IL-17A and IL-22 concentrations in psoriasis patients. XIST silencing suppressed M5-induced keratinocyte proliferation and restrained the discharge of inflammatory cytokines (TNF-α, IL-17A, IL-22) and chemokines (CXCL1, CXCL8, CCL20). XIST can sponge miR-338-5p, and miR-338-5p downregulation abolished the inhibitory effect of XIST silencing on cell proliferation and inflammation. miR-338-5p was at high expression in the clinical serum samples from psoriasis patients. The target relationship between miR-338-5p and IL-6 was proved. CONCLUSION LncRNA XIST is highly expressed in the serum of patients with psoriasis, and was positively correlated with disease severity and inflammation. XIST may regulate keratinocyte proliferation and inflammation via regulating miR-338-5p/IL-6 axis.

Abstract
OBJECTIVE This study aimed to explore the dysregulated long non-coding RNA (lncRNA) expression profile in psoriatic tissue vs. normal skin tissue via RNA sequencing (RNA-seq), then further sort candidate lncRNAs to be validated by reverse transcription quantitative polymerase chain reaction (RT-qPCR), in order to investigate the comprehensive linkage of lncRNA with psoriasis. METHODS Twenty-five psoriasis patients were consecutively enrolled, with their psoriatic and surrounding normal skin tissues obtained. Ten pairs of psoriatic and normal tissues were proposed to RNA-seq. Then, top 6 differentially expressed lncRNAs (DElncRNA) were sorted as candidate lncRNAs for validation by RT-qPCR in 25 pairs of samples. RESULTS Principal component analysis (PCA) exhibited that lncRNA profile clearly distinguished psoriatic tissue from normal tissue, so did heatmap. Volcano plot disclosed 412 upregulated and 625 downregulated DElncRNAs in psoriatic tissue vs. normal tissue. Gene Ontology (GO) and Kyoko Encyclopedia of Genes and Genomes (KEGG) enrichment analyses exhibited that these DElncRNAs were mainly enriched in immune, inflammation, or proliferation-related biological processes and pathways such as neutrophil degranulation, regulation of immune response, positive regulation of cell proliferation, and MAPK signaling pathway. By RT-qPCR validation, lncRNAs RP11-22A3.2, RP11-342L8.2, and CTD-2006H14.2 were increased (all P < 0.001), while lncRNAs AP000442.4, CCDC144NL-AS1, and MIR663AHG were decreased (all P < 0.01) in psoriatic tissue vs. normal tissue. Interestingly, psoriatic lncRNA RP11-342L8.2 was also observed to positively correlated with psoriasis area and severity index (PASI) (r = 0.405, P = 0.045). CONCLUSION Our present study exhibits some evidence for the landscape of lncRNAs implicated in psoriasis.

Abstract
Psoriasis is a chronic disabling complex inflammatory disorder prevalent worldwide with environmental and genetic components that involve predominantly skin in addition to nails and joints associated with various systemic comorbidities having periods of exacerbations and remissions. Psoriasis is characterized by hyper-proliferation as well as abnormal differentiation of epidermal keratinocytes and lymphocyte infiltration (mainly T cells) with resultant inflammatory cytokines and chemokines. Immunological and genetic studies over the last decade have identified genetic susceptibility risk alleles, molecular, cellular and immunological mechanisms involved in immunopathogenesis of psoriasis. The current disease model emphasizes the role of aberrant Th1 and Th17 responses regulated by a complex network of different cytokines, including TNF-α, IL-17 and IL-23; signal transduction pathways downstream to the cytokine receptors; and various activated transcription factors, including NF-κB, interferon regulatory factors and signal transducer and activator of transcriptions. Cytokines targeting biologics (IL-17, IL-23 and TNFα) therapies have revolutionized the management of severe skin disease having beneficial effects on joints and systemic inflammation of psoriasis as well. Further better understanding of immunopathogenesis of psoriasis will pave way for precision medicine based on specific immunopathogenic targets in a given phenotype of disease. Complex interplay of psoriasis with associated comorbidities is also a future area of research for overall better patient management and to improve their quality of life.

Abstract
MALAT1 is a long non-coding transcript that affects immune reactions, thus being involved in the pathoaetiology of immune-related conditions. We investigated the associations between two genetic variants in MALAT1 and susceptibility to psoriasis in the Iranian population. The G allele of rs619586 has been shown to be less common among cases versus controls (odds ratios (OR; 95% confidence intervals (CI)) = 0.57 (0.36-0.9)), adjusted p = .02). This single nucleotide polymorphism has been associated with the risk of psoriasis in a dominant model (AG + GG vs. AA: OR (95% CI) = 0.56 (0.35-0.92), adjusted p = .04) as well as log-additive model (OR (95% CI) = 0.59 (0.38-0.92), adjusted p = .04). The rs3200401 was not associated with psoriasis in any of the supposed inheritance models. This study potentiates rs619586 as a risk locus for psoriasis in the Iranian population.
