The long noncoding RNA LUCAT1 (lung cancer-associated transcript 1) has been reported to be highly expressed in bladder cancer samples, but its role and molecular mechanisms need to be elucidated.

Bioinformatics methods show that miR-181c-5p is a target of LUCAT1. Here, we aimed to reveal whether LUCAT1 participates in the development of bladder cancer via targeting miR-181c-5p. The expression levels of LUCAT1 and miR-181c-5p were detected by RT-PCR technology in bladder cells and tissues. The effects of the LUCAT1/miR-181c-5p axis on cell proliferation, migration, invasion, and apoptosis were tested by CCK-8, wound healing, Transwell chambers, and flow cytometry assays. The expressions of apoptosis/migration-related proteins were detected by western blotting assays.

The results demonstrated that LUCAT1 was overexpressed in bladder cancer tissue and cells, while miR-181c-5p showed a low expression pattern as compared to normal bladder cells and tissues. Cell proliferation, migration, and invasion capacities were significantly impaired, and cell apoptosis was enhanced when LUCAT1 was silenced in UM-UC-3 and T24 cell lines, but this effect was abolished by miR-181c-5p downregulation. In addition, miR-181c-5p downregulation impaired LUCAT1 downregulation which mediated the decreased expressions of Bcl2 and N-cadherin and the increased expressions of Bax and E-cadherin. Moreover, we found that KRAS was a direct target of miR-181c-5p and was under the positive regulation of LUCAT1.

Collectively, this study reveals that knockdown of LUCAT1 inhibits the migration and invasion of bladder cancer cells in a miR-181c-5p-dependent manner, which may be related to KRAS downregulation.

Endometrial cancer (EC) is one of the most common malignant gynaecological tumours worldwide. This study was aimed at identifying EC prognostic genes and investigating the molecular mechanisms of these genes in EC.

Two mRNA datasets of EC were downloaded from the Gene Expression Omnibus (GEO). The GEO2R tool and Draw Venn Diagram were used to identify differentially expressed genes (DEGs) between normal endometrial tissues and EC tissues. Then, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed using the Database for Annotation, Visualization and Integrated Discovery (DAVID). Next, the protein-protein interactions (PPIs) of these DEGs were determined by the Search Tool for the Retrieval of Interacting Genes (STRING) tool and Cytoscape with Molecular Complex Detection (MCODE). Furthermore, Kaplan-Meier survival analysis was performed by UALCAN to verify genes associated with significantly poor prognosis. Next, Gene Expression Profiling Interactive Analysisugh integrated bioinformatics approaches, we found three significant prognostic genes of EC, which might be potential therapeutic targets for EC patients.The defective MEK/ERK signaling pathway and downstream hypomethylation pattern of lymphocytes are crucial for the pathogenesis of systemic lupus erythematosus (SLE). However, the role that the mesenchymal stem cells play in the MEK/ERK signaling pathway and DNA methylation of peripheral blood mononuclear cells (PBMC) from SLE patients remains unknown. In this study, we found that the MEK/ERK signaling pathway of PBMC from SLE patients was activated after the coculture with bone marrow-derived mesenchymal stem cells (BM-MSC) compared with that from the control group. In addition, the expression level of DNA methyltransferase 1 (DNMT1) increased while the levels of CD70, integrin, alpha L (ITGAL), selectin-l, and IL-13 were reduced in PBMC from SLE patients. However, no obvious effect of BM-MSC on PBMC from healthy controls was observed. These findings revealed that BM-MSC might downregulate the expression of methylation-sensitive genes and then suppress the autoactivated PBMC via the MEK/ERK signaling pathway. https://www.selleckchem.com/products/SB-202190.html And it may be one of the mechanisms that BM-MSC ameliorated SLE.Nonluminal breast cancer has high early metastasis and treatment resistance, and neoadjuvant chemotherapy (NAC) is needed. The presence of cancer stem cells (CSC) and epithelial-mesenchymal transition (EMT) leads to poor prognosis. This study investigated the changes in CSC markers and EMT markers after NAC in nonluminal breast cancer and their correlation with contrast-enhanced ultrasound (CEUS) features and chemotherapy efficacy. Before NAC, the range of nonluminal breast cancer on CEUS was larger than that of two-dimensional ultrasound, but after NAC, it was significantly smaller than that of two-dimensional ultrasound and closer to the postoperative pathological size. After NAC, the enlarged lesions and perfusion defects were significantly less than those before NAC. The time-intensity curve showed the characteristics of slow-in, low enhancement, and low perfusion. Nonluminal breast cancer downregulated the expression of CSC markers and EMT markers after NAC, but the epithelial phenotype of nonluminal breast cancer with good response to chemotherapy was upregulated. In nonluminal breast cancer with poor response to chemotherapy, markers of CSC and EMT were highly expressed before chemotherapy. In conclusion, CEUS is better than conventional ultrasound in estimating NAC efficacy in this mode. CEUS can also predict the prognosis of nonluminal breast cancer before NAC with the characteristics of enhanced enlargement and perfusion defects. The contrast-enhanced time-intensity curve of lesions with relatively poor blood supply may have more CSC and EMT characteristics.
Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for portal hypertensive complications. Little is known about the ability of spleen stiffness (SS) for predicting the survival of cirrhotic patients undergoing TIPS. This study is to evaluate the influence of SS detected by point shear wave elastography (pSWE) in predicting survival after TIPS.

This retrospective cohort study screened consecutive patients who underwent TIPS and reliable pSWE measurement between October 2014 and September 2017 from our prospectively maintained database. SS values were measured before TIPS. The primary endpoint was the overall survival after TIPS. The Cox regression analysis model was used for univariate and multivariate analyses. A receiver operating characteristic (ROC) curve analysis was performed to calculate the sensitivity, specificity, and positive and negative predictive values.

A total of 89 patients were involved in the final analysis. 24 patients (27.0%) died during a median follow-up time of 31 m.
