The reno-protective effect of Empagliflozin against carbon tetrachloride (CCl4)-induced nephrotoxicity in mice halting JNK/MKK4/NRF2/NF-KB pathway.

AIM: This study designed to evaluate the reno-protective effects of Empagliflozin (EMPA), a sodium-glucose co-transporter 2 (SGLT2) inhibitor, against carbon tetrachloride (CCl4)-induced nephrotoxicity in mice targeting JNK/MKK4/NRF2/NF-KB pathway.

METHODS

Male albino mice were given EMPA (10 mg/kg, orally) for 4 weeks prior to a single i.p. injection of 10 % CCl4 (20 ml/kg). Mice were sacrificed 48 h post CCl4 injection.

KEY FINDINGS: EMPA attenuated CCl4-induced renal injury, as reflected by a decrease in serum urea and creatinine levels, also preserved the histological integrity of kidney tissue. Theses reno-protective effects of EMPA can be mainly due to its 1. Antioxidant, (↑CAT, ↑SOD, ↑Nrf-2 and ↑ARE), 2. Anti-inflammatory (↓NF-κB and ↓TNF-α) and 3. Anti-apoptotic (↓Caspase-3) proprieties. EMPA also inhibited JNK/MKK4 signaling pathway, which plays a critical role in kidney damage.

CONCLUSION

These finding confirm the reno-protective effect of EMPA with a modulatory impact on JNK/MKK4/Nrf2/NF-κB signaling network; suggesting its therapeutic utility to minimize acute kidney injury (AKI) in clinical setting in the future.
