Project description:A lung cancer cell model of invasive transformation was developed to select progressively invasive cell populations from a parental cell line of human lung adenocarcinoma, CL1. Five progressive sub-clones namely, CL1-1, CL1-2, CL1-3 CL1-4, and CL1-5 were selected using transwell and displayed increasing invasion potential (Chu et al, 1997). Here, we used microarrays to analyze and compare gene expression profiles between CL1-0 and CL1-5 for the identification of invasion/metastasis associated gene signatures.
Project description:Thermococcus sp. 2319x1E is able to grow on different mono- or polysaccharides as carbon source, including xylan. To investigate xylan degradation in Thermococcus sp. 2319x1E, cells were grown on 4 different carbon sources for 12 h (mid-exponential phase) and harvested by centrifugation. Using a label-free quantification approach the whole proteomes were analyzed. In another experiment a glycosidase specific activity-based probe (JJB384) was used to isolate specific Thermococcus glycosidases activated during growth on xylan or xylose.

Here, we used microarrays to analyze and compare gene expression profiles between CL1-0 and CL1-5 for the identification of invasion/metastasis associated gene signatures. CL1-0 and CL1-5 lung cancer cell lines were used for RNA extraction and hybridization on Affymetrix microarrays. A total of 6 chips were used for microarray analysis including three biological repeats from CL1-0 and three biological repeats from CL1-5.
