Colon cancer progression-polysomal difference

ABSTRACT: Two colon cancer cell lines are under study. SW480 and SW620. The first one is derived from primary cancer, SW620 are from lymphnode metastatic sites. they both comes from the sampe patient. Polisomal RNA fractions from the two isogenic colon cancer cells lines was purified by sucrose gradient and hybridized on affymetrix hgu133a chips. this study is complementary to the series GSE1323 were total RNA was used instead. Comparison between the polysomal fraction chips and the total RNA chips is performed and the analysis proposed in a paper from the authors (at the moment in preparation). Keywords: other

Project description:Protein extraction and proteolytic digestion were performed using a Filter-Assisted Sample Preparation (FASP) protocol. In case of phosphopeptide enrichment immobilized Fe(III) affinity chromatography (Fe-IMAC) was performed. The peptides were fractionated using an HPLC system fitted with an SCX column. 10 sample datasets were used: 1. CRC_N: Normal tissue samples were obtained from 20 colorectal cancer patients, no quantification.Phosphopeptide enrichment was performed. 2. CRC_T: Human colorectal cancer tissue samples were obtained from 20 patients, no quantification. Phosphopeptide enrichment was performed. 3. CRC_iTRAQ: Human colorectal cancer tissue samples were obtained from 24 patients, iTRAQ quantification. 4. CRC_phospho_iTRAQ:Human colorectal cancer tissue samples were obtained from 24 patients, iTRAQ quantification.Phosphopeptide enrichment was performed. 5. HCT116_iTRAQ: Human colon cancer cell HCT116, iTRAQ quantification. 6. HCT116_phospho_iTRAQ: Human colon cancer cell HCT116, phosphopeptide enrichment, iTRAQ quantification. 7. SW_SILAC_HL: Human colon cancer cell SW480 and SW620, SW480 and SW620 were grown in SILAC media, containing l-arginine (Arg0) and l-lysine (Lys0) (SW480; light), or 13C615N4-l-arginine (Arg10) and 13C6-l-Lysine (Lys6) (SW620; heavy). 8. SW_SILAC_LH: SW480 and SW620 were grown in SILAC media, containing l-arginine (Arg0) and l-lysine (Lys0) (SW620; light), or 13C615N4-l-arginine (Arg10) and 13C6-l-Lysine (Lys6) (SW480; heavy). 9. SW_phospho_SILAC_HL: SW480 and SW620 were grown in SILAC media, containing l-arginine (Arg0) and l-lysine (Lys0) (SW480; light), or 13C615N4-l-arginine (Arg10) and 13C6-l-Lysine (Lys6) (SW620; heavy). Phosphopeptide enrichment was performed. 10. SW_phospho_SILAC_LH: SW480 and SW620 were grown in SILAC media, containing l-arginine (Arg0) and l-lysine (Lys0) (SW620; light), or 13C615N4-l-arginine (Arg10) and 13C6-l-Lysine (Lys6) (SW480; heavy). Phosphopeptide enrichment was performed. For creation of xml and mgf files, Proteome Discoverer 1.3 and Mascot v2.3 software were used.
