OBJECTIVE The aim of this study was to screen differentially expressed micro ribonucleic acids (miRNAs) in the plasma of patients with cerebral infarction (CI). In addition, the role of miR-150-5p in the incidence of CI is mainly explored via animal models and molecular biology experiments. PATIENTS AND METHODS Blood samples were collected from hospitalized patients diagnosed with CI, including 15 CI patients and 15 non-CI patients as negative controls. Differentially expressed miRNAs in the plasma of these subjects were screened by microarray analysis. TargetScan was applied to predict the target genes of miR-150-5p, which were subjected to GO and pathway enrichment analyses using WebGestalt. Sprague-Dawley rats were randomly divided into Sham group (n=20), Control group (n=20), and Experimental group (n=20). CI model in rats was established in the latter two groups. Rats in Experimental group and Control group were intravenously injected with miR-150-5p mimics or miR-negative control (NC), respectively. The expressions of vital genes in the Wnt signaling pathway, including p53, Cyclin D1 (CCND1), c-Myc, β-catenin (CTNNB1) and Survivin were detected by Western blot in rats at 3 d after injection. RESULTS A total of 3,568 differentially expressed miRNAs were detected in the peripheral blood between CI patients and controls, whose 2,100 were upregulated, including miR-150-5p (p less then 0.05). The target genes of miR-150-5p were involved in molecular pathways, such as the Wnt signaling pathway, carcinogenesis, endocrine regulation, and infection. Compared with rats in Control group, the protein expression of p53 was downregulated (p less then 0.05), while CCND1, c-Myc, CTNNB1 and Survivin were upregulated (p less then 0.05) in Experimental group. GNE-7883 research buy CONCLUSIONS MiR-150-5p regulates the Wnt signaling pathway and participates in cell proliferation and apoptosis by downregulating p53, which may be a potential mechanism of CI induction.OBJECTIVE This study aims to investigate the value and determine the accuracy of two kinds of scoring models in predicting the degree of esophageal varices (EV) and esophageal variceal bleeding (EVB) in patients with liver cirrhosis (LC). PATIENTS AND METHODS A total of 189 patients with LC, who underwent esophagogastroduodenoscopy (EGD), color Doppler ultrasound (CDU), and computed tomography (CT), were retrospectively analyzed. Then, the routine blood examination, liver function test, M-index of the spleen in CT, EGD, and CDU results were recorded. According to the EGD result, these patients were divided into five groups varicose bleeding group, severe varices group, moderate varices group, mild varices group, and no varices group. Then, the receiver operating characteristic curves of all predicting parameters studied were respectively drawn, the area under the receiver operating characteristic curves were calculated, and the predictive value of EV and EVB was evaluated. RESULTS The area under the receiver operating characteristic curve of the VAP score model and Plt/S-D score model was 0.901 and 0.835, respectively. The VAP score model cut-off value of 461.5 for predicting moderate esophageal varices (MoEV), severe esophageal varices (SEV), and EVB has a specificity and sensitivity of 100% and 68.7%, respectively, while the Plt/S-D score model cut-off value of 835.5 for predicting MoEV, SEV, and EVB has a specificity and sensitivity of 95.1% and 58.2%, respectively. CONCLUSIONS These two kinds of scoring models can predict the degree of esophageal varices and bleeding in liver cirrhosis patients and has good predictive accuracy.The increasing incidence of chronic pathologies and especially non-AIDS defining cancers, such as lung cancer, hepatocellular carcinoma, breast cancer, colorectal cancer, prostate cancer, and Hodgkin’s lymphoma after the introduction of combined antiretroviral therapy requires the infectious diseases specialist to know how and when to suspect and diagnose cancer in people living with HIV. The aim of this review is to provide updated studies and information about non-AIDS defining cancers and their management in PLWH sheading a light on possible futures scenarios.OBJECTIVE The RIB43A domain with coiled-coils 2 (RIBC2) encodes an uncharacterized vertebrate protein exhibiting similarity with Chlamydomonas protofilament ribbon proteins, required for ciliary motility. To date, no functional variants capable of triggering a change in the expression of RIBC2 have been reported. PATIENTS AND METHODS The genotypes of rs2272804 in 30 individuals were identified with Sanger sequencing to estimate allele frequencies. Dual-Luciferase and mutagenesis assays were carried out to investigate the impact of rs2272804 on transcriptional and translational levels. The microarray data of 7 types of cancer were obtained from the Gene Expression Omnibus (GEO) to explore the role of rs2272804 in those diseases. RESULTS In this study, we identified a common variant in the 5’UTR of RIBC2, rs2272804, which can create an upstream open reading frame (uORF) in the 5’UTR significantly inhibiting the expression of its host gene. Using Dual-Luciferase constructs, we found that this variant leads to ants identified a common variant that exerts a dramatic impact on expression efficiency and provides further functional insight into RIBC2.OBJECTIVE Anaplastic lymphoma kinase (ALK) gene has been demonstrated to be rearranged, mutated or amplified in several haematological and solid tumors. Moreover, the use of ALK inhibitors has recently revolutionized the treatment of ALK-rearranged patients affected by non-small cell lung carcinoma. Herein we review the genetic alterations of ALK in melanocytic neoplasms described in literature, focusing on their potential diagnostic and predictive role. MATERIALS AND METHODS The Authors reviewed the pertinent literature through research on PubMed server was performed typing the terms “ALK”, “Anaplastic lymphoma kinase”, “ALKATI”, “Melanoma”, “Spitz”, “Spitzoid”. RESULTS ALK translocations were demonstrated in melanocytic neoplasms, particularly in acral melanoma and spitzoid tumors. ALKATI was described in primary and metastatic melanoma, indicating its early occurrence in oncogenesis, with varying immunohistochemical expression of the protein. CONCLUSIONS The identification of the specific type of ALK mutations could be interesting for planning biologic therapy of melanoma patients.
