Dinuclear Tridentate Ru(II) Complex with Strong Near-Infrared Light-Triggered Anticancer Activity.

The design of the dinuclear Ru(II) complex () with strong near-infrared (NIR) absorption properties has been reported for efficient anticancer phototherapy. Under 700 nm LED light excitation, exhibited remarkable synergistic type I/II photosensitization ability and photocatalytic activity toward intracellular biomolecules. showed impressive 700 nm light-triggered anticancer activity under normoxia and hypoxia compared with the clinically used photosensitizer Chlorin e6.

A 700 nm LED Light Activated Ru(II) Complex Destroys Tumor Cytoskeleton via Photosensitization and Photocatalysis.

Photoactivable chemotherapy (PACT) using metallic complexes provides spatiotemporal selectivity over drug activation for targeted anticancer therapy. However, the poor absorption in near-infrared (NIR) light region of most metallic complexes renders tissue penetration challenging. Herein, an NIR light triggered dinuclear photoactivable Ru(II) complex (Ru2) is presented and the antitumor mechanism is comprehensively investigated.

Long noncoding RNA XIST promotes malignancies of esophageal squamous cell carcinoma via regulation of miR-101/EZH2.

The long non-coding RNA XIST is a long non-coding RNA that associates with polycomb repressive complex 2 to regulate X-chromosome inactivation in female mammals. The biological roles as well as the underlying mechanisms of XIST in esophageal squamous cell carcinoma remained yet to be solved. Our data indicated that XIST was significantly upregulated in esophageal squamous cancerous tissues and cancer cell lines, as compared with that in the corresponding non-cancerous tissues and immortalized normal squamous epithelial cells.

Serum microRNA profiles as diagnostic biomarkers for HBV-positive hepatocellular carcinoma.

Background & Aims: The discovery of effective and reliable biomarkers to detect hepatitis B virus (HBV)-positive hepatocellular carcinoma (HCC) at an early stage may improve the survival of HCC. The aim of this study was to establish serum microRNA (miRNA) profiles as diagnostic biomarkers for HBV-positive HCC.

Methods: We used deep sequencing to screen serum miRNAs in a discovery cohort (n=100).

MicroRNA-152 Targets Phosphatase and Tensin Homolog to Inhibit Apoptosis and Promote Cell Migration of Nasopharyngeal Carcinoma Cells.

BACKGROUND Nasopharyngeal carcinoma (NPC) is a type of head and neck cancer with very high prevalence in southern China. Phosphatase and tensin homolog (PTEN), a tumor suppressor, was reported to be downregulated in NPC patients and correlated with pathological grade and clinical stage of NPC. MATERIAL AND METHODS Luciferase reporter assay, qPCR, and Western blot analysis were used to determine if PTEN is a target of miR-152.

Serum microRNA profiles as prognostic biomarkers for HBV-positive hepatocellular carcinoma.

To establish serum microRNA profiles as prognostic biomarkers in hepatocellular carcinoma patients (HCCs), we used deep sequencing to screen serum microRNAs in a discovery set .Twelve up-regulated serum miRNAs were selected for qPCR analysis in a training set. MiR-192-5p and miR-29a-3p were identified and associated with HCC prognosis.

[Expression and clinical significance of PDGFRalpha and PDGFRbeta in colorectal cancer].

Background & Objective: Platelet-derived growth factor receptor-alpha (PDGFRalpha) and -beta (PDGFRbeta) play important roles in the invasion and metastasis of solid tumors. However, their correlations to colorectal cancer have seldom been reported. This study was to detect the expression of PDGFRalpha and PDGFRbeta in colorectal cancer, and investigate their clinical significance.
