Figure Lengend Snippet: The influence of TF extracellular domain peptide constructs on proliferative signalling in MDA-MB-231 cells. MDA-MB-231 cells (1.5 × 10 5 ) were transfected to express TED, LED, UED, EGF4-βTD or the control peptide. ( A ) Cells were lysed with Laemmli buffer, and Western blot analysis was carried out using antibodies against total ERK1/2, phosphorylated ERK1/2 and GAPDH. Images represent 3 separate experiments. ( B ) Band intensities were quantified using ImageJ, and the ratio of pERK/tERK was calculated. ( C ) Cells were lysed, and the mRNA was extracted and converted to cDNA using cell-2-cDNA kit. The expression of cyclin D1 and β-actin mRNA were measured using RT-PCR and the relative cyclin D1 expression levels calculated using the 2 −ΔΔCq method. ( D ) MDA-MB-231 cells (5 × 10 4 ) were transfected to express TED, LED, UED, EGF4-βTD or control peptide. The cells were incubated for 72 h, and the number of cells was determined using the crystal violet assay.
Article Snippet: The wells were washed three times with PBST and then incubated with the rabbit polyclonal anti-β1-integrin antibody specific for the EGF4-βTD domains (1:100 v / v in PBST; PA1-37318; ThermoFisher, Loughborough, UK) for 90 min at room temperature.
