Tors on oral cancer progression, and may facilitate the improvement of novel treatments for human oral cancer. Extra filesAdditional file 1: Suplemetary supplies and Strategies. Further file 2: Figure S1. SHP1 transcriptional level is not associated with hugely invasive ability in oral cancer cells. No important difference in SHP1 transcript was observed in between parent and extremely invasive clones IL-22 Protein Purity & Documentation derived from HSC3 cells. The expression of SHP1 for HSC3-Inv4 and HSC3-Inv8 was normalized to HSC3 parental cells. Data are representative of 3 independent experiments. Additional file three: Figure S2. SHP2 catalytic-defective expressing cells showed enhanced tyrosine phosphorylation of protein. The cells expressing SHP2 wild sort or CS mutant were lysed, and subjected toWang et al. BMC Cancer 2014, 14:442 http:biomedcentral1471-240714Page 12 ofimmunoblotting with anti-phospho-tyrosine. Data are representative of 3 independent experiments. Extra file 4: Figure S3. Profile of SHP2 activity in oral cancer cell lines (OC3, OECM1, HSC3, and SCC4). Experiments had been accomplished in triplicate at least, and values are indicated as mean SD. HOK, normal cells. More file 5: Figure S4. SHP2 negatively regulates EGFR activity in oral cancer cells. Total cell lysates have been ready, and SHP2 was immunoprecipitated from HSC3 cells expressing EGFP-tagged SHP2 wild sort or catalytic-defective SHP2 (SHP2CS). SHP2 in association with active EGFR in these cells was detected by SDS-PAGE and immunoblotting with anti-phospho-EGFR, EGFR, and SHP2. GAPDH as loading control. Data are representative of three independent experiments. Abbreviations ERK: extracellular signal-related kinase; PARP: Poly ADP-ribose polymerase; SHP2: Src-homology 2 domain-containing tyrosine phosphatase two.
