Epidermal growth factor receptor tyrosine kinase inhibitors gefitinib and erlotinib have been widely used in patients with non-small-cell lung cancer. Unfortunately, the efficacy of EGFR-TKIs is limited because of natural and acquired resistance. As a novel cytoprotective mechanism for tumor cell to survive under unfavorable conditions, autophagy has been(More)
PURPOSE Metabolic phenotyping has provided important biomarker findings, which, unfortunately, are rarely replicated across different sample sets due to the variations from different analytical and clinical protocols used in the studies. To date, very few metabolic hallmarks in a given cancer type have been confirmed and validated by use of a metabolomic(More)
Human microRNA-9 (miR-9) has been reported to be involved in the metastasis of several malignancies including brain breast cancer. However, its role in the metastasis of colorectal cancer (CRC) remains to be revealed. Here, we evaluated miR-9 expression in metastatic CRC and investigated its effects on the motility and proliferation of RKO cells. The(More)
Autophagy is a critical survival pathway for cancer cells under conditions of stress. Thus, induction of autophagy has emerged as a drug resistance mechanism. This study is to determine whether autophagy is activated by a novel multikinase inhibitor linifanib, thereby impairing the sensitivity of hepatocellular carcinoma (HCC) cells to this targeted(More)
PURPOSE Secreted protein acidic and rich in cysteines-like 1 (SPARCL1) is an extracellular matrix glycoprotein with malignancy-suppressing potential. The hypothesis that SPARCL1 reduces cancer invasiveness and predicts better survival in colorectal cancers (CRC) was investigated. EXPERIMENTAL DESIGN Stable SPARCL1 transfectants, RKO-SPARCL1, and(More)
Most of colorectal adenocarcinomas are believed to arise from adenomas, which are premalignant lesions. Sequencing the whole exome of the adenoma will help identifying molecular biomarkers that can predict the occurrence of adenocarcinoma more precisely and help understanding the molecular pathways underlying the initial stage of colorectal tumorigenesis.(More)
BACKGROUND There is currently very little data available on the consistency of quantitative and qualitative faecal immunochemical test (FIT) for colorectal cancer screening. METHODS A representative random population (n=1889, 40-74 year olds) in Jiashan, China was invited for FIT screening in 2012. Faecal samples were collected by a single specimen(More)
BACKGROUND Tumor radioresistance often leads to treatment failure during radiotherapy. New strategies like developing radiosensitizer are clinically important. Intervention with DNA double-strand break repair is an effective way to modulate tumor cell radiosensitivity. This study focused on the mutant Artemis fragment-enhanced radiosensitivity of human(More)
The aim of this study was to evaluate the performance of qualitative and quantitative fecal immunochemical tests (FITs) in population screening for colorectal neoplasm. A total of 9000 participants aged between 40 and 74 years were enrolled in this study. Each participant received two stool sampling tubes and was asked to simultaneously submit two stool(More)
ST14 (suppression of tumorigenicity 14) is a transmembrane serine protease that contains a serine protease catalytic (SP) domain, an SEA domain, two complement subcomponent C1r/s (CUB) domains, and four low density lipoprotein receptor class A domains. Glutathione S-transferase fusion proteins with SP, CUB, and low density lipoprotein receptor domains and(More)
