ChIP - Anti-Smad2 + Smad3 antibody [EPR19557-4] - ChIP Grade (AB202445)

Chromatin was prepared from HaCaT (Human keratinocyte cell line) cells treated with 7ng/ml TGF-β for 1h and non-treated according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25μg of chromatin, 2μg of ab202445 (blue), and 20μl of Anti rabbit IgG sepharose beads. 2μg of rabbit normal IgG was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).

Effects of DEK shRNA on Smad, MAPK and PI3K/AKT signalling pathways in BEAS-2B cells. (A-E) The expressions of TGF-β, DEK mad2/3 and Smad4, ERK1/2, p38, JNK, and PI3K, AKT, mTOR were detected by Western blot. The relative density of each protein was calculated. Data were shown as mean ± SD (n = 3). NC, negative control cells; ovDEK, cells transfected with DEK; shNC, cells transfected with scrambled shRNA; shDEK, cells transfected with DEK shRNA. *p < 0.05, vs control group. #p < 0.05, ovDEK vs TGF-β1 + NC group; shDEK vs TGF-β1 + shNC group
