Acquired radioresistance during radiotherapy is considered as the most important reason for local tumor recurrence or treatment failure. Circular RNAs (circRNAs) have recently been identified as microRNA sponges and involve in various biological processes. The purpose of this study is to investigate the role of circRNAs in the radioresistance of esophageal(More)
Radioresistance is considered as the most important reason for local tumour recurrence. This study investigates the role of miRNAs in radioresistant human esophageal cancer cells. Human miRNA microarray has been used to detect the differential expressed microRNAs between radioresistant esophageal cell line KYSE-150R and the parental cell line KYSE-150. The(More)
Mesenchymal stem cells (MSCs)-based therapies have had positive outcomes in animal models of cardiovascular diseases. However, the number and function of MSCs decline with age, reducing their ability to contribute to endogenous injury repair. The potential of stem cells to restore damaged tissue in older individuals can be improved by specific pretreatment(More)
Mitochondrial DNA (mtDNA) D-loop has been identified as a frequent hot spot of mutations in various tumors. The aim here was to investigate the sequence variations of mitochondrial D-loop region in familial nasopharyngeal carcinoma (FNPC) and their possible associations with cancer risk. 29 subjects from 4 Chinese NPC families and 20 sporadic NPC as well as(More)
UNLABELLED OBJECTIVE To assess the efficacy of concurrent chemoradiation with paclitaxel and platinum and external irradiation, and to compare the effect of extensive regional field irradiation with conventional local field irradiation for locally advanced esophageal cancer. METHODS From Oct. 2000 to Jan. 2006, 89 patients with locally advanced esophageal(More)
OBJECTIVE To evaluate the toxicity and clinical efficacy of simultaneous modulated accelerated radiation therapy (SMART) technique for nasopharyngeal carcinoma. METHODS 110 patients with nasopharyngeal carcinoma underwent boost treatment with SMART at the dose of 2.5 Gy/time for 28 times for gross tumor volume (GTV) with the total dose of 70 Gy and the(More)
Macrophage migration inhibitory factor (MIF) is a critical inflammatory cytokine that was recently associated with progenitor cell survival and potently inhibits apoptosis. We examined the protective effect of MIF on hypoxia/serum deprivation (SD)-induced apoptosis of mesenchymal stem cells (MSCs), as well as the possible mechanisms. MSCs were obtained from(More)
Emerging evidences indicate that dysregulated long non-coding RNAs (lncRNAs) are implicated in cancer tumorigenesis and progression and might be used as diagnosis and prognosis biomarker or potential therapeutic targets. Therefore, identification of cancer-associated lncRNAs and investigation of their biological functions and molecular mechanisms are(More)
BACKGROUND AND PURPOSE The purpose of our study is to examine the capacity of cetuximab to reverse radiation resistance and investigate molecular mechanisms in human radiation-resistant esophageal carcinoma cell line KYSE-150R. MATERIALS AND METHODS The radioresistant cell line KYSE-150R was established by using fractionated irradiation (FIR). The(More)
Accumulation of data indicates that misregulated long noncoding RNAs (lncRNAs) are implicated in cancer tumorigenesis and progression and might be served as diagnosis and prognosis biomarker or potential therapeutic targets. Identification of cancer-associated lncRNAs and investigation of their biological functions and molecular mechanisms are significant(More)
