Project description:Human early stage colon adenocarcinoma stem cell line was FACS-sorted for CCR9- and CCR9+ cell groups and differential expression was identified via Wafergen SmartChip RT-PCR gene expression profiling. CCR9- and CCR+ cells were FACS-sorted. 24 hours afterwards, cells were treated with 100ng/ml human CCL25 for 30 min. RNA was extracted from both populations using PureLink RNA Mini kit (Invitrogen) and analyzed using the SmartChip Real-Time PCR System
Project description:By combining deep sequencing with high-throughput quantitative RT-PCR, we reveal that somatic splicing profiles are reorganized to pluripotent splicing profiles during reprogramming from mouse embryonic fibroblasts (MEFs) to induced pluripotent stem (iPS) cells. The splicing pattern in pluripotent stem cells resembles that in testis, and the regulatory regions have specific characters in length and sequence. These results indicate that the dynamic alteration in splicing is an integral part of the molecular network involved in the reprogramming process. Sequencing data from MEF, two iPS cell lines and one ES cell line. RT-PCR data will be represented within Figures or Tables in published manuscripts.
Project description:To the search of new colon tumor biomarkers in the transition from normal colon (NC) mucosa to adenoma (AD) and adenocarcinoma (AC), we integrated microarray data with the results of a high-throughput proteomic workflow. In proteomic study, we used a modified isoelectric focusing protocol on strips with an immobilized pH gradient to separate peptides labeled with iTRAQ (isobaric tags for relative and absolute quantitation) tags followed by liquid chromatography–tandem mass spectrometry analysis.
