11β‑HSD1 inhibition markedly reduced the degree of fibrosis. The cell proliferation was increased, the number of cells in the G0/G1 phase decreased and the number of cells in the S and G2/M phases increased in the pSuper transfected group compared with the N group. In addition, the overexpression of 11β‑HSD1 enhanced the TGF‑β1‑induced activation of LX2‑HSCs and enzyme activity of connective tissue growth factor. 11β‑HSD1 knockdown suppressed cell proliferation by blocking the G0/G1 phase of the cell cycle, which was associated with HSC stimulation and inhibition of 11β‑HSD1 enzyme activity. In conclusion, increased 11β‑HSD1 expression in the liver may be partially responsible for hepatic fibrogenesis, which is potentially associated with HSC activation and proliferation.Myocardial infarction (MI) is a leading cause of mortality due to progression to ventricular arrhythmias (VAs) or heart failure (HF). selleck inhibitor Cardiac remodeling at the infarct border zone (IBZ) is the primary contributor for VAs or HF. Therefore, genes involved in IBZ remodeling may be potential targets for the treatment of MI, but the mechanism remains unclear. The present study aimed to explain the molecular mechanisms of IBZ remodeling based on the roles of long non‑coding RNAs (lncRNAs). After downloading miRNA (GSE76592) and mRNA/lncRNA (GSE52313) datasets from the Gene Expression Omnibus database, 23 differentially expressed miRNAs (DEMs), 2,563 genes (DEGs) and 168 lncRNAs (DELs) were identified between IBZ samples of MI mice and sham controls. A total of 483 DEGs were predicted to be regulated by 23 DEMs, among which Itgam, Met and TNF belonged to hub genes after five topological parameters were calculated for genes in the protein‑protein interaction network. These hub genes‑associated DEMs (mmu‑miR‑181a, mmu‑miR‑762) can also interact with six DELs (Gm15832, Gas5, Gm6634, Pvt1, Gm14636 and A330023F24Rik) to constitute the competing endogenous RNA (ceRNA) axes. Furthermore, a co‑expression network was constructed based on the co‑expression pairs between 44 DELs and 297 DEGs, in which Pvt1 and Bst1 were overlapped with the ceRNA network. Thus, Bst1‑associated ceRNA (Pvt1‑mmu‑miR‑181a‑Bst1) and co‑expression (Pvt‑Bst1) axes were also pivotal for MI. Accordingly, Pvt1 may be a crucial lncRNA for modification of cardiac remodeling in the IBZ after MI and may function by acting as a ceRNA for miR‑181a to regulate TNF/Met/Itgam/Bst1 or by co‑expressing with Bst1.The aim of the present study was to identify novel antibody markers for the early diagnosis of atherosclerosis in order to improve the prognosis of patients at risk for acute ischemic stroke (AIS) and acute myocardial infarction (AMI). A first screening involved the serological identification of antigens by recombinant cDNA expression cloning and identified additional sex combs‑like 2 (ASXL2) as a target antigen recognized by serum IgG antibodies in the sera of patients with atherosclerosis. Antigens, including the recombinant glutathione S‑transferase‑fused ASXL2 protein and its synthetic peptide were then prepared to examine serum antibody levels. Amplified luminescence proximity homogeneous assay‑linked immunosorbent assay, which incorporates glutathione‑donor beads and anti‑human‑IgG‑acceptor beads, revealed significantly higher serum antibody levels against the ASXL2 protein and its peptide in the patients with AIS, diabetes mellitus, AMI, chronic kidney disease, esophageal squamous cell carcinoma, or colorectal carcinoma compared with those in healthy donors. The ASXL2 antibody levels were well associated with hypertension complication, but not with sex, body mass index, habitual smoking, or alcohol intake. These results suggest that the serum ASXL2 antibody marker can discriminate between hypertension‑induced atherosclerotic AIS and AMI, as well as a number of digestive organ cancers.Currently, microglia are considered as crucial factors in suppressing inflammatory reactions, but the specific molecular mechanism remains unknown. To elucidate whether peroxisome proliferator‑activated receptor‑γ (PPAR‑γ) can inhibit neuroinflammatory cytokine expression via the mTOR signal pathway, the BV‑2 cell line was incubated with lipopolysaccharide (10 mM/ml) to induce an inflammatory injury. PPAR‑γ was activated by rosiglitazone, and was inhibited by GW9662. The mTOR signal pathway was activated by phosphatidic acid (P.A.), while it was inhibited by rapamycin. Western blotting and reverse transcription‑quantitative PCR were used to evaluate the expression levels of PPAR‑γ/mTOR signal pathway related proteins and neuroinflammatory cytokines, including NF‑κB, tumor necrosis factor (TNF)‑α and interleukin (IL)‑1β. When treated with P.A., the expression levels of phosphorylated (p)mTOR and p‑ribosomal protein S6 kinase (pS6K) were significantly increased and the expression levels of TNF‑α and IL‑1β were significantly lower. However, the expression of PPAR‑γ was similar in P.A. treated cells and cells treated with rapamycin. When PPAR‑γ was activated, pmTOR and pS6K protein expression levels were significantly decreased, and the mRNA expression levels of TNF‑α and IL‑1β were significantly reduced, but this inhibition could be alleviated by administrating GW9662. Collectively, it was indicated that the mTOR signal pathway may be located downstream of PPAR‑γ. Furthermore, neuroinflammatory reactions could be inhibited via the activation of PPAR‑γ by suppressing the mTOR signal pathway in microglia.Gastric cancer is one of the most common types of cancer worldwide, with a high incidence and mortality rate. MicroRNAs (miRs) play an important role in tumorigenesis, cell proliferation, migration, apoptosis and metastasis of cancer. The present study aimed to investigate the role and potential mechanism of miR‑204‑5p in gastric cancer. The mRNA expression levels of miR‑204‑5p in gastric cancer were determined by reverse transcription‑quantitative PCR. Cell proliferation was determined using Cell Counting Kit‑8 and colony formation assays. Flow cytometry analysis was performed to detect the cell apoptosis rate. Wound healing and Transwell assays were carried out to determine the cell migration and invasion rates, respectively. A putative binding site of miR‑204‑5p in the 3' untranslated region of human epidermal growth factor receptor 2 (HER‑2) was predicted using a bioinformatics algorithm and confirmed using a dual‑luciferase reporter assay. miR‑204‑5p levels were downregulated in gastric cancer cells. Overexpression of miR‑204‑5p significantly inhibited cell proliferation and decreased cell colony formation.
