Effect of exosomal miRNA on cancer biology and clinical applications.

Exosomes, extracellular vesicles with diameters ranging from 30 to 150 nm, are widely present in various body fluids. Recently, microRNAs (miRNAs) have been identified in exosomes, the biogenesis, release, and uptake of which may involve the endosomal sorting complex required for transport (ESCRT complex) and relevant proteins. After release, exosomes are taken up by neighboring or distant cells, and the miRNAs contained within modulate such processes as interfering with tumor immunity and the microenvironment, possibly facilitating tumor growth, invasion, metastasis, angiogenesis and drug resistance.

Both insulin resistance and metabolic syndrome accelerate the progression of chronic kidney disease among Chinese adults: results from a 3-year follow-up study.

Background: Metabolic syndrome (MetS) has been found to be associated with an increased risk for chronic kidney disease (CKD). However, the relationship between insulin resistance (IR), which is believed to play a central role in the pathogenesis of MetS, and CKD is still unclear in Chinese adults and needs further investigation.

Methods: This 3-year follow-up study included 3237 middle-aged and elderly Chinese without CKD at baseline.

Lentivirus-Mediated Overexpression of miR-29a Promotes Axonal Regeneration and Functional Recovery in Experimental Spinal Cord Injury via PI3K/Akt/mTOR Pathway.

MicroRNAs as a novel class of endogenous small non-coding RNAs, modulate negative gene expression at the post-transcriptional level. Our previous work has demonstrated that miR-29a reduces PTEN expression by directly targeting the 3'-UTRs (untranslated regions) of its mRNA, thus promoting neurite outgrowth. To further confirm the role of miR-29a in the recovery of SCI and its potential mechanisms, a recombinant lentiviral vector was used to promote miR-29a expression in the injured spinal cord.

MicroRNAs, long noncoding RNAs, and circular RNAs: potential tumor biomarkers and targets for colorectal cancer.

Noncoding RNAs (ncRNAs) can be divided into microRNAs (miRNAs), long noncoding RNAs (lncRNAs), circular RNAs (circRNAs), pRNAs, and tRNAs. Traditionally, miRNAs exert their biological function mainly through the inhibition of translation via the induction of target RNA transcript degradation. lncRNAs and circRNAs were once considered to have no potential to code proteins.

PTEN-GSK3β-MOB1 axis controls neurite outgrowth in vitro and in vivo.

Mps One binder 1 (MOB1) is a core component of NDR/LATS kinase and a positive regulator of the Hippo signaling pathway. However, its role in neurite outgrowth still remains to be clarified. Here, we confirmed, for the first time, that MOB1 promoted neurite outgrowth and was involved in functional recovery after spinal cord injury (SCI) in mice.

Direct bleaching of a Cr:YAG saturable absorber in a passively Q-switched Nd:YAG laser.

In this work, the anisotropy of nonlinear absorption in a crystal Q-switch was considered when we established coupled rate equations of a passively Q-switched laser. A [100]-cut Cr:YAG crystal, with initial transmission T=40%, was used as the Q-switch to evaluate the theoretical model, and the results of the simulation were in good accordance with the experiment. In order to control timing jitter of the passively Q-switched laser, an actively Q-switched Nd:YAG laser was applied to directly bleach the [100]-cut Cr:YAG crystal.

Energy-Transfer Kinetics for Xe (6p[1/2]) Atoms in Kr, Ar, Ne, and He.

The kinetic processes for the Xe (6p[1/2]) atoms in Kr, Ar, Ne, and He buffer gases were studied. We found that Kr, Ar, and Ne atoms can be used to switch the amplified spontaneous emission (ASE) channel from 3408 nm (6p[1/2]-6s'[1/2]) to 3680 nm (5d[1/2]-6p[1/2]), while Xe and He atoms do not show such a phenomenon. This ASE channel switch is mainly ascribed to the fast transfer of 6p[1/2] → 5d[1/2].

The association between inflammation, the microbiome and urethane-induced pulmonary adenocarcinoma.

Lung cancer is amongst the most common types of cancer throughout the world. The overall 5-year survival rate is ~17%. A number of studies have demonstrated that the microbiome existing within the host may affect the level of inflammation, and consequently contribute to the carcinogenesis of certain types of cancer.

The design and rationale of the Beijing Vascular Disease Patients Evaluation Study (BEST study).

Aims: Arteriosclerosis and arterial stiffness increasing are the basic pathophysiological changes of vascular-related diseases, and also the predictor factors of future cardiovascular events. Plasma biomarkers such as glucose, lipids, Homocysteine (Hcy), N-terminal pro-brain natriuretic peptide (NT-proBNP) have been shown to be involved the development of arteriosclerosis. The present study is a prospective observational and follow-up study of the characteristics of subclinical vascular disease detected by non-invasive methods that can predict progression of clinical overt vascular events in a Chinese population.

Emerging role of exosome-derived long non-coding RNAs in tumor microenvironment.

Exosomes are extracellular vesicles released by many cell types and have been attributed for their roles in many diseases including cancer. Exosomes secreted by tumor cells and stromal cells are critical mediators of intercellular communication in tumor microenvironments. Long noncoding RNAs (lncRNAs) are selectively sorted into exosomes and can regulate cancer onset and progression in a variety of ways.

MiR-760 suppresses human colorectal cancer growth by targeting BATF3/AP-1/cyclinD1 signaling.

Background: Recent studies have reported that microRNAs (miRNAs) often function as negative post-transcriptional regulators with altered expression levels found in colorectal cancer (CRC). There have been few studies on miRNAs that regulate the oncogenic alterations in CRC. Here, we aim to explore the anti-cancer miRNA and the potential mechanisms by which miRNAs modulate CRC progression.

The Biological Effect and Clinical Application of Long Noncoding RNAs in Colorectal Cancer.

Colorectal cancer (CRC) is one of the most common malignancies in the world. Easier recurrence and metastasis is the main cause of mortality in CRC patients, and the markers applied for diagnosis and treatment of CRC is still urgently needed to early diagnose and evaluate therapeutic effect. Long noncoding RNA (lncRNA) is a class of noncoding RNA that the length is more than 200 nucleotides.

Long non-coding RNAs (lncRNAs) are increasingly implicated in tumorigenesis and cancer progression. This study focused on the relationship between the lncRNA LINC00959 and colorectal cancer (CRC). We found that LINC00959 expression was lower in CRC tissues than normal colorectal mucosae.

Expression of MicroRNA-29a Regulated by Yes-Associated Protein Modulates the Neurite Outgrowth in N2a Cells.

Yes-associated protein (YAP) is proved to increase miR-29a in the present study, but the relevant molecular mechanism is not clear. Also, growing evidence indicates that the high-level miR-29a promotes the neurite outgrowth by decreasing PTEN (phosphatase and tensin homologue deleted on chromosome 10). Results show that the expression of miR-29a increases but the PTEN decreases during transfecting the N2a cells with the YAP plasmid.
