ABSTRACT: To evaluate whether serum microRNAs can predict survival in nasopharyngeal carcinoma (NPC) patients, we analyzed the serum microRNA expression profiles in 8 NPC patients with shorter-survival time and 8 age- and gender-matched NPC patients with longer-survival time using microarray. We identified a four-microRNA signature can predict survival of NPC patients. 8 serum samples from nasopharyngeal carcinoma patients with shorter-survival time and 8 serum samples from nasopharyngeal carinoma patients with longer-survival time
Project description:We used microarrays to perform systematic profiling of human microRNAs in plasma from nasopharyngeal carcinoma (NPC) patients to find potential biomarkers. By comparing the plasma microRNA profiles of the NPC patients and healthy donors, potential biomarkers for NPC were investigated. A total of 39 microRNAs were aberrantly expressed based on 50 Agilent microarrays containing 887 human microRNAs 50 microarrays containing 887 human microRNAs were used to screen for potential biomarkers with significant differential expression levels between 31 NPC patients and 19 healthy donors.

Project description:To explore differentially expressed genes between nasopharyngeal carcinoma (NPC) primary tumors and non-cancerous nasopharyngeal tissues, 18 NPC tissue samples versus 18 control samples were utilized to perform genome-wide expressing profiling. Consequently, 2992 genes were found to be differentially expressed in NPC tissues relative to the control (FC>2, P<0.05). Among these 2992 genes, uPA was ranked as the top one in all upregulated genes sorted by ascending order of P-value. Moreover, expression of uPAR was also upregulated in NPC tissues with FC=3.34 and P=7.52M-CM-^W105. 18 nasopharyngeal carcinoma primary tumors and 18 non-cancerous nasopharyngeal tissues were used to perform genome-wide expressing profiling. The median ages of patients were 46 (range, 19-77) for NPC patients and 45 (range, 18-78) for the non-cancerous cohort. Almost one third of patients were female. All samples were collected before any anti-cancer treatment.
Project description:MicroRNAs are biomarkers of prognosis and survival for many types of cancer. We evaluated whether microRNAs can predict the survival and efficacy of concurrent chemotherapy in nasopharyngeal carcinoma (NPC) patients. We retrospectively analyzed microRNA expression in 312 paraffin-embedded NPC specimens and 18 normal nasopharyngeal tissues using microarray. We found Forty-one microRNAs are differentially expressed between NPC and normal tissues, and a five-microRNA signature can predict survival independent of stage. NPC patients with the low-risk microRNA signature have a favorable response to concurrent chemotherapy. microRNA profiling of nasopharyngeal carcinoma tissues vs. normal nasopharyngeal tissues 312 paraffin-embedded nasopharyngeal carcinoma tissues and 18 paraffin-embedded normal nasopharyngeal tissues
Project description:Serum is a valuable body fluid to diagnose cancer as it can be accessed with minimal invasive techniques. Studying the cancer serum proteome provides valuable insights into the pathophysiology of tumor progression. Gastric adenocarcinoma is an aggressive cancer resulting in poor prognosis, mainly due to the lack of specific early diagnostic biomarkers. To this end, we used an iTRAQ-based quantitative proteomic approach to identify differentially expressed proteins in the sera of patients diagnosed with gastric cancer. Our study resulted in the identification of 643 proteins in the serum, of which 48 proteins were found to be overexpressed and 11 proteins underexpressed in gastric cancer when compared with healthy controls. We used multiple reaction monitoring assays to validate the overexpression of potential biomarkers. This catalog of serum-based biomarkers will aid in diagnosis and prognosis of gastric cancer.

Project description:The objective of our study was to search for survival biomarkers (SB) and treatment response monitoring biomarkers (TRMB) in the urinary proteome of dogs with renal disease secondardy to canine leishmaniosis (CanL),
Project description:Nasopharyngeal carcinoma is a squamous cell carcinoma arising from the nasopharynx epithelium. So far, there have been no effective biomarkers to predict the radiosensitivity of NPC. Based on miRNA profile screened out from NPC patients with different radiosensitivity, this study was conducted to explore the correlation between serum miRNAs and radiotherapy response in NPC, and to identify biomarkers for predicting the radiosensitivity of NPC.
Project description:Lung ischemia-reperfusion (I/R) injury remains one of the common complications after various cardiopulmonary surgeries. I-R injury represents one potentially maladaptive response of the innate immune system which is featured by an exacerbated sterile inflammatory response triggered by tissue damage. Thus, understanding the key components and processes involved in sterile inflammation during lung I-R injury is critical to alter care and extend survival for patients with acute lung injury. We constructed a minipig surgical model of transient unilateral left pulmonary artery occlusion without bronchial involvement to create ventilated lung I-R injury. Lung tissues from minipig with sham operation (one sample), left side lung tissues (the operated side)(one sample) and right side lung tissues (the non-operated side)(one sample) from minipig with lung ischemia-reperfusion were submitted for gene expression array analysis.
