Schizophrenia (SZ) and cancer (Ca) have a broad spectrum of clinical phenotypes and a complex biological background, implicating a large number of genetic and epigenetic factors. SZ is a chronic neurodevelopmental disorder signified by an increase in the expression of apoptotic molecular signals, whereas Ca is conversely characterized by an increase in appropriate molecular signaling that stimulates uncontrolled cell proliferation. The rather low risk of developing Ca in patients suffering from SZ is a hypothesis that is still under debate...

Hyperglycemia serves an important role in the pathogenesis of diabetic cardiomyopathy. The aim of the present study was to investigate whether exogenous hydrogen sulfide (H2S) protects against high glucose‑induced inflammation and cytotoxicity in cardiac cells by inhibiting the p38 mitogen‑activated protein kinase (MAPK)/nuclear factor‑κB (NF‑κB), cyclooxygenase‑2 (COX‑2) and inducible nitric oxide synthase (iNOS) signaling pathways. Rat H9c2 myocardium cells were exposed to 33 mM glucose (high glucose, HG) for 24 h to stimulate HG‑induced cytotoxicity...

Mimotope mapping enables the characterization of allergen epitopes for the development of diagnostic and therapeutic approaches. In the present study, a phage display peptide library was used for mimotope mapping based on the binding of antibodies against the recombinant group 5 allergen from the house dust mite Dermatophagoides farinae (Der f 5), an arthropod that causes indoor allergies worldwide. When three monoclonal anti‑Der f 5 antibodies were used for biopanning, seven mimotopes were identified. Their common subsequence was '‑‑‑[‑A][‑T]W[‑S]H[HSFW][LM][PSKR] [TLV][AST]‑[DP][‑L]‑'...

It has been previously reported that mutations in retinal G protein coupled receptor (RGR) are associated with retinitis pigmentosa. The present study aims to systemically analyze the potential role of variants of RGR in retinal diseases. Variants in coding regions and splice sites of RGR were selected from a whole exome sequencing dataset of 820 probands with various forms of genetic ocular diseases. Potential variants of RGR were further confirmed by Sanger sequencing and analyzed in available family members...

Glioblastoma multiforme is an aggressive malignant brain tumor with terminal consequences. A primary reason for its resistance to treatment is associated with cancer stem cells (CSCs), of which there are currently no effective ways to destroy. It remains unclear what cancer cells become a target of stem cell migration, what the role of this process is in oncogenesis and what stem cell lines should be used in developing antitumor technologies. Using modern post‑genome technologies, the present study investigated the migration of human stem cells to cancer cells in vitro, the comparative study of cell proteomes of certain stem cells (including CSCs) was conducted and stem cell migration in vivo was examined...

The clinicopathological and biological characteristics of squamous cell/adenosquamous carcinoma (SC/ASC) of the gallbladder remain to be fully elucidated, due to the fact that it is a rare gallbladder cancer subtype. In the current study, the expression of minichromosome maintenance complex component 2 (MCM2) and HIV‑1 tat interactive protein 2 (TIP30) was measured in 46 cases of SC/ASC and 80 adenocarcinomas (AC) using immunohistochemistry. Positive MCM2 and negative TIP30 expression were significantly associated with large tumor size, high TNM stage, invasion, lymph node metastasis and lack of surgical curability in SC/ASC and AC...

The current study aimed to investigate the distribution of memory and naïve T cell (TN) subsets in hepatitis B virus (HBV)‑infected patients at different immune stages and investigate the effect of interleukin 33 (IL‑33) on the regulation of the T‑cell subsets. The distributions of memory and naïve T cells were detected by flow cytometry. ELISA was conducted to assess the levels of IL‑4, IL‑5, IL‑10, IL‑12, interferon γ and tumor necrosis factor α. The expression levels of IL‑33 and HBV x protein (HBx) were measured by reverse transcription‑quantitative polymerase chain reaction and western blot analysis, respectively...

Myeloid-derived suppressor cells (MDSCs) are a group of heterogeneous myeloid cells that can suppress antitumor immunity. MDSCs are divided into granulocytic (G‑MDSCs) and monocytic subsets. In the present study, the microRNA profiles of the G‑MDSCs were determined and the differential expression of microRNAs between G‑MDSCs from tumor‑bearing mice and tumor‑free mice was examined. The number of G‑MDSCs in spleens of Lewis lung carcinoma (LLC)‑bearing mice was ~6‑fold higher than in spleens of normal mice (13...

MicroRNAs (miRNAs) are recognized as important regulators of gene expression via translational depression or mRNA degradation. Previously, dysregulated miRNAs have been found in neurodegenerative and neuropsychiatric disorders. Borna disease virus (BDV) is a neurotropic, negative single‑stranded RNA virus, which may be a cause of human neuropsychiatric disease. BDV is regarded as an ideal model to analyze the molecular mechanisms of mental disorders caused by viral infection. In the present study, 10 miRNAs were dysregulated in human oligodendrocytes (OL cells) infected with the BDV strain, Hu‑H1 (OL/BDV)...

Vascular endothelial growth factor (VEGF) serves an important role in promoting angiogenesis and tissue regeneration. However, the lack of an effective delivery system that can target this growth factor to the injured site reduces its therapeutic efficacy. Therefore, in the current study, collagen‑binding VEGF was constructed by fusing a collagen‑binding domain (CBD) to the N‑terminal of native VEGF. The CBD‑VEGF can specifically bind to collagen which is the major component of the extracellular matrix in fibrotic liver...

Ginkgolide B (GB) is one of the ginkgolides isolated from the leaves of the Ginkgo biloba tree. Our previous study indicated that GB promotes the proliferation, migration and adhesion of endothelial progenitor cells, and the induction of angiogenesis through vascular endothelial factor (VEGF). In the present study, the effects of GB on the differentiation of MC3T3‑E1 cells and the signaling pathway involved were investigated in vitro. The MC3T3‑E1 cell viability activities were assessed using an MTS assay...

The effects of hydrogen sulfide (H2S) and the nuclear factor κB (NF-κB) signaling pathway in angiotensin II (AngII)-induced endothelin-1 (ET-1) expression and subsequent cytotoxicity remain unclear. The present study aimed to investigate the hypothesis that H2S protects human umbilical vein endothelial cells (HUVECs) against AngII‑stimulated ET‑1 generation and subsequent cytotoxicity‑induced endoplasmic reticulum stress via the NF‑κB signaling pathway. The results of the present study demonstrated that AngII significantly upregulated the expression levels of ET‑1, glucose‑regulated protein 78, CCAAT‑enhancer‑binding protein homologous protein, phosphorylated (p)‑p65 and inducible nitric oxide synthase; stimulated nitric oxide production; suppressed the expression and activity of cystathionine-γ-lyase (CSE), a H2S synthetase; and decreased cell viability...

Hematological abnormalities are frequently observed in patients with liver cirrhosis (LC). A previous study demonstrated that the apoptosis and damage of endothelial cells could cause the hematological abnormalities in LC. Protein kinases are one of the most important factors that regulate cell behavior, and are potential therapeutic targets for the treatment of a number of diseases. In a previous study, whole genome profiling was used to identify differentially expressed genes in human bone marrow endothelial cells treated with serum from 26 patients with LC...

Calcium oxalate stones account for >80% of urinary stones, however the mechanisms underlying their formation remains to be elucidated. Hyperoxaluria serves an important role in the pathophysiological process of stone formation. In the present study, differences in the miRNA expression profiles between experimental hyperoxaluric rats and normal rats were analyzed, in order to identify target genes and signaling pathways involved in the pathogenesis of hyperoxaluria. Ethylene glycol and ammonium chloride was fed to male hyperoxaluric rats (EXP) and normal age‑matched male rats (CON)...
