Project description:Hypoxic microenvironment plays important roles in the progression of solid tumors including oral squamous cell carcinoma (OSCC). Long noncoding RNAs (lncRNAs) have gained much attention in the past few years. However, it is not clear whether lncRNAs could regulate hypoxia-adaptation of OSCC, and which lncRNAs participate in this process. Using an lncRNA microarray, we analyzed the aberrant lncRNA expression profiles in OSCC tissues compared with paired normal oral mucosa as well as in hypoxic OSCC cells compared with normoxic OSCC cells. Our microarray also identified 942 lncRNAs that were up-regulated and 507 lncRNAs that were down-regulated in cells cultured under hypoxia compared with those cultured under normoxia (Fold Change >= 2.0, P-value <= 0.05). An OSCC cell line Cal-27 was cultured under either 20% O2 (normoxic) or 1% O2 (hypoxic) conditions. Three samples from each group were obtained for microarray study.

Using an lncRNA microarray, we analyzed the aberrant lncRNA expression profiles in OSCC tissues compared with paired normal oral mucosa as well as in hypoxic OSCC cells compared with normoxic OSCC cells. Our data revealed 2053 differentially expressed (Fold Change >= 2.0, P-value <= 0.05) lncRNAs, among which 934 lncRNAs were significantly up-regulated and 1119 lncRNAs were down-regulated in OSCC compared with paired normal mucosa. Six OSCC tissues and paired normal oral mucosa were obtained from 6 patients with OSCC. LncRNA expression profiles were evaluated by an Agilent Human LncRNA Array v3.0 (8 x 60K, Arraystar).

Project description:A gene expression profiles of human oral squamous cell carcinoma lines, HSC-2 and Ca9-22, cultured under hypoxic conditions (1% pO2 for 24 or 48 hours) were compaired with those under normoxic conditions (21% pO2).
Project description:Proteome characterization of mesenchymal stem cells (MSC) and exosomes.
MSCs were cultured in normoxic, hypoxic and in presence of FBS. Exosomes were prepared from normoxic and hypoxic conditions.
Project description:MM1S cells have been cultured under normoxic and hypoxic conditions, and gene expression profiling has been performed using the Affymetrix Human Genome U133 Plus 2.0 array.
Project description:MM1S cells have been cultured under normoxic and hypoxic conditions, and gene expression profiling has been performed using the Affymetrix Human Genome U133 Plus 2.0 array. We used microarrays to dissect the possible changes occurring at the mRNA level in normoxic cells versus hypoxic cells.
