Patients with IC often experience urination problems, such as urinary frequency and urgency, along with pain or discomfort in the bladder area. Therefore, new treatments based on IC etiology are needed. Polydeoxyribonucleotide (PDRN) is a biologic agonist of the adenosine A2A receptor, and PDRN has anti-inflammatory effect and inhibits apoptosis. In the current study, the effect of PDRN on cyclophosphamide-induced IC animal model was investigated using rats.Methodology: To induce the IC animal model, 75 mg/kg of cyclophosphamide was injected intraperitoneally once every 3 days for 10 days. The rats in the PDRN-treated groups were intraperitoneally injected with 0.5 mL physiological saline containing 8 mg/kg PDRN, once a day for 10 days after IC induction.Results: Induction of IC by cyclophosphamide injection caused voiding dysfunction, bladder edema, and histological damage. Cyclophosphamide injection increased secretion of pro-inflammatory cytokines and enhanced apoptosis. In contrast, PDRN treatment alleviated voiding dysfunction, bladder edema, and histological damage. Secretion of pro-inflammatory cytokines and expressions of apoptotic factors were suppressed by PDRN treatment. These changes indicate that treatment with PDRN improves voiding function by ultimately promoting the repair of damaged bladder tissue.Conclusion: The conclusion of this experiment suggests the possibility that PDRN could be used as an effective therapeutic agent for IC.Keywords: interstitial cystitis, adenosine A2A receptor, polydeoxyribonucleotide, voiding function, inflammation, apoptosisKo IGJin JJHwang LKim SHKim CJWon KYNa YGKim KHKim SJDove Medical Pressarticleinterstitial cystitisadenosine a2a receptorpolydeoxyribonucleotidevoiding functioninflammationapoptosisPathologyRB1-214Therapeutics.
