Integrated analysis of long non-coding RNA-microRNA-mRNA competing endogenous RNAregulatory networks in thromboangiitis obliterans
Thromboangiitis obliterans (TAO) is a non-atherosclerotic, segmental, persistent vascular inflammatory illness. Our goal was to discover the underlying mechanisms of lengthy non-coding RNA (lncRNA)-related competing endogenous RNAs (ceRNAs) in TAO. Six blood samples had been collected from sufferers with TAO and wholesome people (three for every class).
Complete RNA was extracted from the blood of every participant and sequenced. Differentially expressed lncRNAs (DE-lncRNAs) and miRNAs (DE-miRNAs) had been screened, and ceRNA networks related to TAO had been constructed. Thereafter, the genes within the ceRNA community had been subjected to practical analyses. Lastly, a ceRNA relationship (lncRNA NEAT1-hsa-miR-1-3p-mRNA GNA12) was chosen for additional validation.
Evaluation revealed that 347 DE-lncRNAs (150 downregulated and 197 upregulated) and 16 DE-miRNAs (three downregulated and 13 upregulated) had been recognized in TAO. Additional, TAO-associated ceRNA networks, which included 219 lncRNAs, 6 miRNAs, and 53 mRNAs, had been proposed and subjected to gene annotation and pathway evaluation. Moreover, NEAT1 and GNA12 ranges had been considerably upregulated, whereas miR-1-3p ranges had been evidently downregulated in TAO sufferers, as in contrast with these in wholesome controls.
Twin luciferase reporter assays confirmed that NEAT1, miR-1-3p, and GNA12 interacted with one another. We report potential TAO-associated ceRNA regulatory networks and recommend activation of NEAT1/miR-1-3p/GNA12 signaling as a novel mechanism for TAO development.
The rising roles of Gα12/13 proteins on the hallmarks of most cancers in stable tumors
G12 proteins comprise a subfamily of G-alpha subunits of heterotrimeric GTP-binding proteins (G proteins) that hyperlink particular cell floor G protein-coupled receptors (GPCRs) to downstream signaling molecules and play vital roles in human physiology. The G12 subfamily accommodates two relations: Gα12 and Gα13 (encoded by the GNA12 and GNA13 genes, respectively) and, as with all G proteins, their exercise is regulated by their skill to bind to guanine nucleotides.
Elevated expression of each Gα12 and Gα13, and their enhanced signaling, has been related to tumorigenesis and tumor development of a number of most cancers sorts over the previous decade. Regardless of these robust associations, Gα12/13 proteins are underappreciated within the discipline of most cancers. As our understanding of G protein involvement in oncogenic signaling has advanced, it has turn into clear that Gα12/13 signaling is pleotropic and prompts particular downstream effectors in numerous tumor sorts. Additional, the expression of Gα12/13 proteins is regulated via a collection of transcriptional and post-transcriptional mechanisms, a number of of that are incessantly deregulated in most cancers.
With the ever-increasing understanding of tumorigenic processes pushed by Gα12/13 proteins, it’s turning into clear that concentrating on Gα12/13 signaling in a context-specific method may present a brand new technique to enhance therapeutic outcomes in plenty of stable tumors. On this overview, we element how Gα12/13 proteins, which had been first found as proto-oncogenes, are actually recognized to drive a number of “classical” hallmarks, and in addition play vital roles within the “rising” hallmarks, of most cancers.
Impression of Oncogenic Targets by Tumor-Suppressive miR-139-5p and miR-139-3p Regulation in Head and Neck Squamous Cell Carcinoma
We newly generated an RNA-sequencing-based microRNA (miRNA) expression signature of head and neck squamous cell carcinoma (HNSCC). Evaluation of the signature revealed that each strands of some miRNAs, together with miR-139-5p (the information strand) and miR-139-3p (the passenger strand) of miR-139, had been downregulated in HNSCC tissues.
Evaluation of The Most cancers Genome Atlas confirmed the low expression ranges of miR-139 in HNSCC. Ectopic expression of those miRNAs attenuated the traits of most cancers cell aggressiveness (e.g., cell proliferation, migration, and invasion). Our in silico analyses revealed a complete of 28 putative targets regulated by pre-miR-139 (miR-139-5p and miR-139-3p) in HNSCC cells. Of those, the GNA12 (guanine nucleotide-binding protein subunit alpha-12) and OLR1 (oxidized low-density lipoprotein receptor 1) expression ranges had been recognized as unbiased elements that predicted affected person survival in keeping with multivariate Cox regression analyses (p = 0.0018 and p = 0.0104, respectively).
Direct regulation of GNA12 and OLR1 by miR-139-3p in HNSCC cells was confirmed via luciferase reporter assays. Furthermore, overexpression of GNA12 and OLR1 was detected in medical specimens of HNSCC via immunostaining. The involvement of miR-139-3p (the passenger strand) within the oncogenesis of HNSCC is a brand new idea in most cancers biology. Our miRNA-based technique will enhance information on the molecular pathogenesis of HNSCC.
Identification of GNA12-driven gene signatures and key signaling networks in ovarian most cancers
With the give attention to defining the oncogenic community stimulated by lysophosphatidic acid (LPA) in ovarian most cancers, the current research sought to interrogate the oncotranscriptome regulated by the LPA-mediated signaling pathway. LPA, LPA-receptor (LPAR) and LPAR-activated G protein 12 α-subunit, encoded by G protein subunit α 12 (GNA12), all serve an vital function in ovarian most cancers development.
Whereas the overall signaling mechanism regulated by LPA/LPAR/GNA12 has beforehand been characterised, the worldwide transcriptomic community regulated by GNA12 in ovarian most cancers pathophysiology stays largely unknown. To outline the LPA/LPAR/GNA12-orchestrated oncogenic networks in ovarian most cancers, transcriptomic and bioinformatical analyses had been carried out utilizing SKOV3 cells, by which the expression of GNA12 was silenced.
Array evaluation was carried out in Agilent SurePrint G3 Human Comparative Genomic Hybridization 8×60 microarray platform. The array outcomes had been validated utilizing Kuramochi cells. Gene and practical enrichment analyses had been carried out utilizing Database for Annotation, Visualization and Built-in Discovery, Search Device for Retrieval of Interacting Genes and Cytoscape algorithms.
The outcomes indicated a paradigm by which GNA12 drove ovarian most cancers development by upregulating a pro-tumorigenic community with AKT1, VEGFA, TGFB1, BCL2L1, STAT3, insulin-like progress issue 1 and progress hormone releasing hormone as important hub and/or bottleneck nodes. Furthermore, GNA12 downregulated a growth-suppressive community involving proteasome 20S subunit (PSM) β6, PSM α6, PSM ATPase 5, ubiquitin conjugating enzyme E2 E1, PSM non-ATPase 10, NDUFA4 mitochondrial complex-associated, NADH:ubiquinone oxidoreductase subunit B8 and anaphase selling advanced subunit 1 as hub or bottleneck nodes.
Along with offering novel insights into the LPA/LPAR/GNA12-regulated oncogenic networks in ovarian most cancers, the current research recognized a number of potential nodes on this community that may very well be assessed for focused remedy.
Prognostic Worth of Eight-Gene Signature in Head and Neck Squamous Carcinoma
Head and neck most cancers (HNC) is the fifth most typical most cancers worldwide. On this research, we carried out an integrative evaluation of the invention set and established an eight-gene signature for the prediction of prognosis in sufferers with head and neck squamous cell carcinoma (HNSCC).
Univariate Cox evaluation was used to establish prognosis-related genes (with P < 0.05) within the GSE41613, GSE65858, and TCGA-HNSC RNA-Seq datasets after information assortment. We carried out LASSO Cox regression evaluation and recognized eight genes (CBX3, GNA12, P4HA1, PLAU, PPL, RAB25, EPHX3, and HLF) with non-zero regression coefficients in TCGA-HNSC datasets.
Survival evaluation revealed that the general survival (OS) of GSE41613 and GSE65858 datasets and the progression-free survival(DFS)of GSE27020 and GSE42743 datasets within the low-risk group exhibited higher survival outcomes in contrast with the high-risk group. To confirm that the eight-mRNA prognostic mannequin was unbiased of different medical options, KM survival evaluation of the precise subtypes with totally different medical traits was carried out.
