a NF-κB p65/Lamin-A/C expression before and after bleomycin treatment. An upregulation of NF-κB p65 expression is seen on day 7 after bleomycin instillation that persists up to day 14 and further increases on day 28, compared to control. b Densitometric analysis of the NF-κB p65 and Lamin-A/C (74 kDa and 65 kDa respectively) protein bands shows significant upregulation of NF-κB p65 protein expression from day 7 onwards up to day 28. **p < 0.001 group II C, D vs. group I; *p < 0.05 group II B vs group I
