WT SM3, antisense calponin 2 cDNA transfected (AS#I-5) and sense calponin 2 cDNA transfected (S#105) cells were studied using 2D-DIAS. The values are presented as means ± SD and statistical analysis was performed using Student’s t test after testing normality and equal variance. Mann–Whitney rank sum test was used where normality or equal variance failed in Student’s t test. P < 0.05 is considered significant (indicated with bold font).
