(a) Relative protein expression of several
molecular markers in
different treatment groups, (b) quantitative estimation of the relative
protein expression, (c) pull down assay showing EZH2 and Ub interaction,
and (d) quantification of pull down assay showing increased expression
of ubiquitin in 4HPRNP treated group (n = 3; *p < 0.05, **p < 0.01, and ***p < 0.001 considered significant compared to the control
group).
