Flow Cytometry

Flow Cytometry

Flow cytometric analysis of Jurkat cells, untreated (green), or LY294002, Wortmannin and U0126-treated (blue), using Phospho-S6 Ribosomal Protein (Ser235/236) (2F9) Rabbit mAb (Alexa Fluor® 488 Conjugate) (#4854).

IF-IC

IF-IC

Confocal immunofluorescent analysis of two Gefinitib (Iressa) treated non-small cell lung cancer cell lines. HCC827 cells have the E746_A750 deletion in exon 19 of the EGFR gene, and are highly sensitive to Gefitinib. H1975 cells have the (T790M) mutation that confers Gefitinib-resistance. Both cell lines were treated and then double-labeled with Phospho-S6 Ribosomal Protein Rabbit mAb (Alexa Fluor® 488 Conjugate) #4854 and Phospho-Tyrosine Mouse mAb (Alexa Fluor® 647 Conjugate) #9415. Untreated HCC827 (A) and H1975 (C) cells show bright phospho-S6 (green) and phospho-tyrosine (red pseudocolor) label. Phospho-S6 and phospho-tyrosine signals dramatically decrease following Gefitinib treatment in HCC827 cells (B), with little or no change in the Gefitinib-resistant H1975 cells (D).

Confocal immunofluorescent analysis of rat brain showing the hippocampus (left) and striatum (right) labeled with Phospho-S6 Ribosomal Protein (Ser235/236) (2F9) Rabbit mAb (Alexa Fluor® 488 Conjugate) (green), EGR1 Antibody (red) #4152, and Phospho-Histone H3 (Ser10) (6G3) Mouse mAb #9706 (blue) following ischemia with 30 minute reperfusion.


バックグラウンド

One way that growth factors and mitogens effectively promote sustained cell growth and proliferation is by upregulating mRNA translation (1,2). Growth factors and mitogens induce the activation of p70 S6 kinase and the subsequent phosphorylation of the S6 ribosomal protein. Phosphorylation of S6 ribosomal protein correlates with an increase in translation of mRNA transcripts that contain an oligopyrimidine tract in their 5' untranslated regions (2). These particular mRNA transcripts (5'TOP) encode proteins involved in cell cycle progression as well as ribosomal proteins and elongation factors necessary for translation (2,3). Important S6 ribosomal protein phosphorylation sites include several residues (Ser235, Ser236, Ser240, and Ser244) located within a small, carboxy-terminal region of the S6 protein (4,5).
