Abstract Artemis is a key protein of NHEJ (nonhomologous end joining), which is the major pathway for the repair of IR-induced DSBs in mammalian cells. However, the expression of Artemis in tumors and the influence of silencing Artemis on tumor sensitivity to radiation have not been investigated fully. In this study, we investigated how the expression levels of Artemis may affect the treatment outcome of radiotherapy and chemotherapy in colorectal cancer cells. First, we found that the expression of Artemis is strong in some human rectal cancer samples, being higher than in adjacent normal tissues using immunohistochemical staining. We then knocked… More >

Abstract Colon cancer is the third major cause of cancer deaths, accounting for about 8% in terms of mortality globally. The present study aims to explore the effect of silencing Astrocyte Elevated Gene-1 (AEG-1), a metastasis mediating factor, and how it interacts with Exostosin-1 (EXT-1) protein to inhibit the proliferative and invasive potential in colon cancer cells. Forward siRNA transfection was performed using AEG-1 siRNA in SW480 and SW620 colon cancer cell lines, and the expression levels of mRNA and protein were analyzed by Real-time PCR and Immunofluorescence. A simple bioinformatics approach was carried out to identify the possible interactions between… More >

Abstract UQCRC1 is one of the 10 mitochondrial complex III subunits, this protein has a role in energy metabolism, myocardial protection, and neurological diseases. The upstream mechanism of the UQCRC1 protective effect on cardiomyocytes is currently unavailable. In order to explore the upstream molecules of UQCRC1 and elucidate the protective mechanism of UQCRC1 on cardiomyocytes in more detail, we focused on the nuclease-sensitive elementbinding protein 1 (YB-1). We hypothesized YB-1 acts as an upstream regulatory molecule of UQCRC1. This study found that YB-1 RNAi significantly reduces the expression of the UQCRC1 protein level (p < 0.05) and obviously decreases the mitochondrial… More >

Abstract The present study aims to explore the effects of p53 and its target gene Rap2B on the autophagy of U2OS cells. U2OS cells were treated with siRNA against p53, Rap2B, and PLCε. Relative expressions of p53, Rap2B, and PLCε were determined using quantitative polymerase chain reaction (qPCR) and Western blotting, respectively. Levels of IP3 in the cells were determined using Enzyme-linked Immunosorbent Assay (ELISA). Levels of Ca²⁺ were detected using Flow cytometry. Fluorescence microscopy was used to observe the autophagy of cells. Knockdown of p53 significantly decreased the expressions of Rap2B protein. Additionally, knockdown of p53 significantly decreased the mRNA… More >
