Induction of chronic asthma up regulated the transcription of senile factors in male rats.
Background: The main characteristic of asthma is chronic inflammation. We examined cellular senescence by histology and molecular assay in the lungs of a rat model of asthma. This model comprises sensitization by several intraperitoneal injections of ovalbumin with aluminium hydroxide, followed by aerosol challenges every other day.
Results: Data showed that asthma induction caused histological changes including, hyperemia, interstitial pneumonia, fibrinogen clots, and accumulation of inflammatory cells in the pleura. There is an elevation of IL-1β and NF-kB proteins in the asthmatic group (P < 0.001) compared to the control group. The expression of ß-galactosidase increased (P < 0.01), while the expression of Klotho and Sox2 genes was decreased in the lung tissue of the asthmatic group (P < 0.01).
Conclusion: Taken together, these findings suggest that asthmatic conditions accelerated the cellular senescence in the lung tissue.
