Project description:Gene expression profile of platelets. In this study, we try to address the knowledge gap regarding liquid biopsy markers for early detection of non-small cell lung cancer (NSCLC) and head and neck squamous cell carcinoma (HNSCC). For that blood samples were collected in two time points, in the presence and absence of NSCLC or HNSCC. Platelets were isolated and gene expression evaluated by microarray technique.
Project description:LncRNA expression profiles were sucessfully contructed in 370 patients with NSCLC and 198 corresponding adjacent noncancerous tissues using a custom microarray containing probes for 2412 lncRNAs and an outcome prediction of lncRNA signature was successfully identified for predicting prognosis in NSCLC.
Project description:Head and neck squamous cell carcinomas are heterogeneous neoplasms that show clinical and biological differences in association with the human papillomavirus (HPV). To provide adequate therapeutic strategies, biological and clinical characterization is essential to stratify patients based on prognostic and predictive factors. Reports on HNSCC are scarce in Mexico, thus in the present study, we analyze 414 cases of HNSCC, including those of the oropharynx (OPSCC), larynx (LASCC), and oral cavity (OCSCC). We determined the presence of HPV and p16 expression. Global expression profiles were analyzed with Affymetrix HTA 2.0 microarray in 25 selected cases HPV+/p16+ versus HPV-/p16-. In our study we analyze 25 samples derived from HNSCC patients. 18 samples were HPV-/p16- and 7 HPV+/p16+. We compared the HPV-/p16- versus the HPV+/p16+ and identified differentially expressed RNAs with a fold change greater than 1.5 or less than -1.5. These data were used to obtain 98 genes that are differentially expressed in absence of HPV. The present study offers information regarding clinical and molecular characteristics of HNSCC, both associated and unassociated with HPV, in Mexican patients.
Project description:Exosomes were isolated from plasma of n = 12 healthy donors (HD) and n = 16 head and neck cancer (HNSCC) patients. miRNA profiling of exosomes was performed using nCounter SPRINT system. miRNAs being predicted to target EMT-related genes (CDH1, VIM, TWIST1 and SNAI1/2) were selected and compared between HD and HNSCC patients.
Project description:Gene expression profile of platelets have been explored due to their stability and abundance in plasma. In this study, we try to address the knowledge gap regarding liquid biopsy markers for early detection of non-small cell lung cancer (NSCLC). For that blood samples were collected in two time points, in the presence and absence of NSCLC. Platelets were isolated and miRNA expression evaluated by microarray technique.
