Integrated Analyses of lncRNA and mRNA Profiles Reveal Characteristic and Functional Changes of Leukocytes in Qi-Deficiency Constitution and Pi-Qi-Deficiency Syndrome of Chronic Superficial Gastritis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:8518053. [PMID: 32724329 PMCID: PMC7381957 DOI: 10.1155/2020/8518053] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/07/2019] [Revised: 06/02/2020] [Accepted: 06/15/2020] [Indexed: 01/07/2023]
Abstract
Methods We adopted RNA-sequencing approach to identify differential lncRNAs and genes in leukocytes, clustered expression profiles, and analyzed biological functions and pathways of differential genes to decode their potential roles in contributing to characteristics and functions of leukocytes. In addition, interaction networks were created to detail the interactions between differential genes. In particular, we explored differential lncRNAs-mediated regulation of differential genes and predicted the subcellular location of lncRNAs to reveal their potential roles. Results Compared with TCM-defined balanced constitution (BC), 183 and 93 genes as well as 749 and 651 lncRNAs were differentially expressed (P < 0.05 and |log2 (fold change)| ≥1) in leukocytes of individuals from case populations 1 (QDC) and 2 (PQDS), respectively. Of them, 12 genes and 111 lncRNAs were common to each case population. Several networks were created to detail the interactions among case-specific genes, especially case-specific lncRNAs-mediated regulation of case-specific genes. Also, interaction networks were created for the common lncRNAs and genes. HCL analyses showed that differential genes and lncRNAs, especially the common genes and lncRNAs, kept similar expression patterns in both case populations. Furthermore, function enrichment analyses just indicated the common biological processes, namely, extracellular matrix organization and cell adhesion via plasma membrane adhesion molecules. In addition, most common genes underwent very tight and complex regulation of many trans- and cis-acting lncRNAs. In particular, of them, ADAMTSL5, COL26A1, COL27A1, MSH5, and LOC390937 could be regulated by multiple case-specific and common lncRNAs, including the means that directs binding of the common lncRNAs to their coded proteins. The common changes in the extracellular matrix and integral components of plasma membrane related to cell-cell adhesion/junction and communication may implicate the linkage between QDC and PQDS, contributing to alterations in characteristics and functions of leukocytes. Conclusions These results may provide new insights into the characteristic and functional changes of leukocytes in QDC and PQDS, especially the mechanism underlying the linkage of QDC to PQDS, with potential leukocytes biomarkers for future application in integrative medicine.

J Cell Biochem 2019; 120:12300-12310.

Abstract
The disorders of hemostasis and coagulation were believed to be the main contributors to the pathogenesis of pulmonary thromboembolism (PTE), and platelets are the basic factors regulating hemostasis and coagulation and play important roles in the process of thrombosis. This study investigated the proteome of human umbilical vein endothelial cells (HUVECs) with platelet endothelial aggregation receptor-1 (PEAR1) knockdown using the isobaric tags for relative and absolute quantitation (iTRAQ) method and analyzed the role of differential abundance proteins (DAPs) in the regulation of platelets aggregation. Our results showed that the conditioned media-culturing HUVECs with PEAR1 knockdown partially suppressed the adenosine diphosphate (ADP)-induced platelet aggregation. The proteomics analysis was performed by using the iTRAQ technique, and a total of 215 DAPs (124 protein was upregulated and 91 protein were downregulated) were identified. The Gene Ontology (GO) enrichment analysis showed that proteins related to platelet α granule, adenosine triphosphate metabolic process, and endocytosis were significantly enriched. Further, the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis also identified the significant enrichment of endocytosis-related pathways. The real-time polymerase chain reaction assay confirmed that the expression of P2Y12 , mitochondrial carrier 2, NADH dehydrogenase (ubiquinone) iron-sulfur protein 3, and ubiquinol-cytochrome c reductase hinge protein are significantly downregulated in the HUVECs with PEAR1 knockdown. In conclusion, our in vitro results implicated that DAPs induced by PEAR1 knockdown might contribute to the platelet aggregation. Proteomic studies by employing GO enrichment and KEGG pathway analysis suggested that the potential effects of DAPs on platelet aggregation may be linked to the balance of ADP synthesis or degradation in mitochondria.
