Liuweidihuang Pill Alleviates Inflammation of the Testis via AMPKSIRT1NF-κB Pathway in Aging Rats

Abstract EN

Liuweidihuang Pill (LP) is a traditional Chinese herbal formula that is often used in clinical practice to treat kidney deficiency syndrome.

The present study investigated the antiaging effects of LP in a D-galactose- (D-Gal-) induced subacute aging rat model.

The study also attempted to explore whether anti-inflammatory mechanisms that underpin the antiaging effects are mediated by the AMPK/SIRT1/NF-κB signaling pathway.

Rats were subcutaneously injected with D-Gal at a dosage of 100 mg/kg/d for 8 weeks.

Upon successful induction of aging in the rats, the animal was administered LP at 0.9 g/kg/d by gavage for 4 weeks.

Proteins of the testis were subsequently examined by western blot analysis, and associated locations in the testicular tissue were determined by immunohistochemistry.

We observed that LP exerted antiaging effects in aging rats following the activation of AMPK/SIRT1.

It was also observed that LP inhibited the expression of NF-κB, thereby further attenuating inflammation of the testis.

Therefore, LP can alleviate inflammation of the testis via the AMPK/SIRT1/NF-κB pathway in aging rats.
