Membrane was washed with TBS Tween-20 and incubated with all the 1:10000 dilution of secondary antibody to rabbit IgG - H&L for 1 h at room temperature. Protein band was developed by enhanced chemiluminescence. The membrane was re-probed with anti GAPDH antibody for normalization of expression. The densities of immunoreactive bands were quantitated by the Quantity One 1-D image analysis software program. antibody diluted with TBS in 1:100 ratio. Slides were washed 1655472 thrice for 5 minutes in TBST and incubated for 1 hour with Horse raddish peroxidase conjugated anti rabbit antibody diluted with TBS in 1:200 ratio. After washing, slides were incubated with 3,39-diaminobenzidine tetrahydrochloride and immediately washed under tap water after the color development and were counter stained with haematoxylin. Slides were DPX mounted and observed under light microscope. Cloning and reporter gene assay Immunostaining of FoxC2 antigen in 875320-29-9 cost tissue specimens 5 mm paraffin embedded tissue sections were de-paraffinized in xylene and endogenous peroxidase activity was quenched with 3% H2O2 in methanol by incubating for 30 minutes. Sections were rehydrated through graded alcohols and antigen retrieval was performed by incubating in 10 mM sodium citrate at 90uC for 15 mins. Sections were washed with TBST and then blocked with 3% BSA for 20 mins. Slides were incubated with anti- FoxC2 FoxC2 in Chronic Venous Disease given in table S2. The conditions for amplifying FoxC2 and GAPDH are as described earlier. For assessing Hey2, Dll4, COUP TFII and Ephrin B4 gene expression, the reactions were performed in triplicate in 96-well plates at 48uC, 30 min; 95uC, 10 min; followed by 40 cycles of 95uC, 15 s; and 61uC, 1 min. The realtime PCR products were re-confirmed by electrophoresis on 2% agarose gels. The amount of the target relative to GAPDH mRNA was expressed as 2 2. er were transfected into cultured cell lines using Lipofectamine. Renilla luciferase construct was used as a control for transfection efficiency. After 48 h, each group of cells was lysed and luciferase assay was carried out using Dual Luciferase assay kit according to manufacturer's instructions and readings were recorded. Technical replicates were performed in triplicate and biological experiments were performed twice. Statistical analysis Hardy-Weinberg equilibrium was tested for a goodness-of-fit using a Chi square test. Chi-square test was used to investigate the possible association between polymorphisms and CVD in casecontrol studies. Student's t test was used to analyze the difference in luciferase, mRNA transcripts and protein expression levels. Information collected from answered questionnaires and medical records were entered into MS Excel and analyzed using SPSS 16. Differences between groups were considered significant for p values less than 0.05. FoxC2 construct and transfection of EA.hy926 cells FoxC2 pCAGIG construct was made by inserting FoxC2 coding sequence into EcoRI and XhoI restriction sites of pCAGIG mammalian expression vector . EA.hy926 cells were plated into 6-well plates and the cells were allowed to adhere for 24 hours. Transfection of FoxC2 -pCAGIG and control empty vector was performed using lipofectamine-2000 according to the manufacturer's recommendation. The concentrations of constructs used were 1 mg per well. After 6 hours of transfection, 20% FBS supplemented DMEM medium was added.
