AIM To investigate the effect of astilbic acid (3beta, 6beta-dihydroxyolean-12-en-27-oic acid, AA) on human colorectal carcinoma COLO 205 cell proliferation and apoptosis. METHODS Proliferation of COLO 205 cells was measured by MTT assay. Content of DNA in COLO 205 cell was measured by modified diphenylamine assay. AA-induced morphological changes was observed with fluorescence microscope and...

BACKGROUND The expression of miR-205 is closely related to the occurrence, development, and prognosis of lung cancer and breast cancer. However, studies show that it plays opposite roles in different tumor types. Because the expression and regulation of miR-205 are primarily confined to epigenetic areas, whether genetic variation of miR-205 is related to the occurrence or to the development of ...

Tumour cells associated with therapy resistance (radioresistance and drug resistance) are likely to give rise to local recurrence and distant metastatic relapse. Recent studies revealed microRNA (miRNA)-mediated regulation of metastasis and epithelial-mesenchymal transition; however, whether specific miRNAs regulate tumour radioresistance and can be exploited as radiosensitizing agents remains ...

Purpose: Accumulating evidence has demonstrated the great potential of circulating microRNAs (miRs) as noninvasive tumor biomarkers. Our study aimed to measure the expression level of serum miR-205 in patients with gastric cancer (GC) and investigate its clinical significance. Methods: Serum miR-205 levels in 145 GC patients and 145 healthy controls were detected by RT-PCR. Then, the associatio...

We have recently demonstrated that synthetic CpG oligonucleotides (ODNs), which function as potent immunostimulators, bind to the multi-lectin receptor DEC-205, resulting in their internalization. DEC-205-deficient mice exhibit impaired dendritic-cell and B-cell maturation, impaired cytokine responses and suboptimal cytotoxic T-cell responses. As murine and human DEC-205 are highly conserved, C...

OBJECTIVE MiR-30a and miR-205 are two miRNAs downregulated in prostate cancer and are involved in autophagy regulation. However, how they are downregulated in prostate cancer is still not clear. In this study, we firstly investigated the association between miR-30a and miR-205 downregulation and hypoxia in prostate cancer. Then, we further investigated the regulative effect of miR-30a on TP53IN...

PURPOSE Our goal was to target melanoma antigens to the dendritic cell-specific receptor DEC-205. DEC-205 is an antigen receptor expressed on dendritic cells and has been shown to guide antigens to MHC class I and II compartments for processing and presentation to T cells. EXPERIMENTAL DESIGN The melanoma tumor-associated antigen (TAA), gp100, was fused to the single-chain fragment variable (...
