Introducing graphitic carbon nitride nanosheets as supersandwich-type assembly on porous electrode for ultrasensitive electrochemiluminescence immunosensing.

Biomarkers in blood or tissue provide essential information for clinical screening and early disease diagnosis. However, increasing the sensitivity of detecting biomarkers remains a major challenge in a wide variety of electrochemical immunoassays. Herein, we present an electrochemiluminescence (ECL) immunosensing strategy with 1: N amplification ratio (target-to-signal probe) for biomarkers detection on a porous gold electrode.

HMGB3 promotes growth and migration in colorectal cancer by regulating WNT/β-catenin pathway.

Colorectal cancer (CRC) is the third leading cause of cancer-related deaths and a major health problem. High mobility group box 3 (HMGB3), a member of the high-mobility group box (HMGB) family, was reported to be over-expressed in gastric carcinoma and bladder cancer. However, the function of HMGB3 in CRC remains unclear.

Long non-coding RNA CASC11 interacts with hnRNP-K and activates the WNT/β-catenin pathway to promote growth and metastasis in colorectal cancer.

The abnormal expression of many long non-coding RNAs (lncRNAs) has been reported in the progression of various tumors, and these lncRNAs can be useful as diagnostic indicators and anti-tumor targets. Therefore, it is important to identify lncRNAs that can be used for the clinical prevention and treatment of colorectal cancer (CRC). Here, we report that cancer susceptibility candidate 11 (CASC11) was upregulated in CRC tissues; increased CASC11 expression in CRC was associated with tumor size, serosal invasion, lymph metastasis, and the tumor-node-metastasis (TNM) stage.

Loss of TINCR expression promotes proliferation, metastasis through activating EpCAM cleavage in colorectal cancer.

Long non-coding RNAs (lncRNAs) are involved in kinds of human diseases, including colorectal cancer (CRC). TINCR, a 3.7 kb long non coding RNA, was associated with cell differentiation in keratinocyte and gastric cancer cells.

IFN-γ-mediated IRF1/miR-29b feedback loop suppresses colorectal cancer cell growth and metastasis by repressing IGF1.

To investigate the clinicopathological significance and underlying mechanism of microRNA-29b (miR-29b) in colorectal cancer (CRC), the role of miR-29b was investigated using in vivo and in vitro assays. Luciferase reporter assays were conducted to determine the association between miR-29b and the insulin-like growth factor 1 (IGF1) 3' untranslated region (3'UTR). Chromatin immunoprecipitation (ChIP) assays were employed to assess the direct binding of interferon regulatory factor 1 (IRF1) to miR-29b.

Revealing the anti-tumor effect of artificial miRNA p-27-5p on human breast carcinoma cell line T-47D.

microRNAs (miRNAs) cause mRNA degradation or translation suppression of their target genes. Previous studies have found direct involvement of miRNAs in cancer initiation and progression. Artificial miRNAs, designed to target single or multiple genes of interest, provide a new therapeutic strategy for cancer.

Prediction of human miRNAs using tissue-selective motifs in 3' UTRs.

MicroRNAs (miRNAs) play an important role in posttranscriptional regulation of genes. We developed a method to predict human miRNAs without requiring cross-species conservation. We first identified lowly/moderately expressed tissue-selective genes using EST data and then identified overrepresented motifs of seven nucleotides in the 3' UTRs of these genes.
