MicroRNAs (miRNAs) are important regulators of pathobiological processes in various cancer. In the present study, we demonstrated that miR-93 expression was significantly up-regulated in gastric cancer tissues compared with that in matched normal mucosal tissues. High expression of miR-93 was significantly associated with lymph node metastasis and tumor-node-metastasis (TNM) stage. Functionally, ectopic expression of miR-93 promoted cell proliferation, migration, invasion, EMT phenotypes, and repressed apoptosis and G1 cell cycle arrest in vitro, and promoted tumor formation in vivo...

Glioma is the most common type of primary brain tumors in the central nervous system (CNS). Migfilin occurs in human glioma and enhances cellular motility via the epidermal growth factor receptor (EGFR) pathway. However, the underlying molecular mechanism is not fully understood. In this study, we found that Migfilin promoted matrix metalloproteinase-2 (MMP-2) activity, and restrained the expression of tissue inhibitor of metalloproteinase 2 (TIMP2), which is an MMP-2 inhibitor. Functional and structural studies showed that the LIM1 domain of Migfilin was required for Migfilin-mediated TIMP2 expression inhibition and MMP-2 activity, and was also necessary in promoting cell motility...

BACKGROUND AND PURPOSE: Acute Kidney Injury (AKI) is a severe complication affecting many hospitalized patients after cardiac surgery, with negative impacts on short- and long-term clinical outcomes and on healthcare costs. Recently, clinical interest has been aimed at defining and classifying AKI, identifying risk factors and developing diagnostic strategies to identify patients at risk early on. Achieving an early and accurate diagnosis of AKI is a crucial issue, because prevention and timely detection may help to prevent negative clinical outcomes and avoid AKI-associated costs...

BACKGROUND: Multiple aberrant microRNA expression has been reported in gastric cancer. Among them, microRNA-335-5p (miR-335), a microRNA regulated by DNA methylation, has been reported to possess both tumor suppressor and tumor promoter activities. RESULTS: Herein, we show that miR-335 levels are reduced in gastric cancer and significantly associate with lymph node metastasis, depth of tumor invasion, and ultimately poor patient survival in a cohort of Amerindian/Hispanic patients...

Recent studies using microarray-based approaches have demonstrated that microRNAs (miRNAs) are involved in pain processing pathways. However, a significant proportion of computational predictions of miRNA targets are false-positive interactions. To increase the chance of identifying biologically relevant targets, we performed an integrated analysis of both miRNA and mRNA expression profiles in the rat spinal cord during complete Freund's adjuvant (CFA)-induced inflammatory pain. We generated miRNA and mRNA arrays from the same corresponding samples on Days 5 and 14 after CFA injection...

Selective gene activation with the dCas9 (deactivated clustered regularly interspaced short palindromic repeats [CRISPR] associated protein 9)/CRISPR targeting of a transcriptional activator effector is now well established. However, the optimal targeting of guide RNA (gRNA) for a given gene is largely a matter of trial and error. We explored the optimal targeting site for tissue inhibitor of metalloproteinases (TIMPs) by first screening multiple gRNA target sites using a luciferase-based promoter-reporter system and next confirmed the effective TIMP induction in the mouse motor neuron-like neuron-enriched spinal cord 34 (NSC34) cells...

Myopia and astigmatism, two common refractive errors frequently co-exist, are affecting vision at all working distances in the affected populations worldwide. Eyeballs having these refractive errors are known to exhibit abnormal eye shape at the anterior and posterior eye segments, but whether the outer coats of these abnormal eyeballs, cornea anteriorly and sclera posteriorly, are regulated by region-specific molecular mechanism remains unclear. Here we presented the changes in mRNA expression levels of three genes (MMP2, TIMP2, and TGFB2), all known to participate in extracellular matrix organization, at five regions of the cornea and sclera in chickens developing high myopia and astigmatism induced by form deprivation...

OBJECTIVES: Patellar tendinopathy (PT) is a debilitating and prevalent condition that tends to affect those who are physically active or engaged in jumping sports. Although tendinopathies are known to have a genetic basis, the role of DNA methylation as an epigenetic factor and risk determinant for human PT has never been described. We sought to determine whether differences existed between the methylation profiles of both the TIMP2 and ADAMTS4 gene promoter sequences in a cohort of males having undergone surgery for patellar tendinopathy compared to controls...

Long-term exposure to fine particulate matter (PM2.5) may cause adverse pregnancy outcomes but the mechanisms are not clear. Our research confirms that PM2.5 induced DNA damage, and inhibited cell proliferation in HTR-8/SVneo cells, presenting in a dose- and time-dependent manners. Using quantitative proteomics, the 182 and 486 differentially expressed proteins in cells treated with 120μgml(-1) PM2.5 for 24 and 48h were involved in many critical biological processes, including of cell proliferation, response to DNA damage, regulation of small GTPase mediated signal transduction, and etc...
