Coomassie brilliant blue G-250 dye attenuates bleomycin-induced lung fibrosis by regulating the NF-κB and NLRP3 crosstalk: A novel approach for filling an unmet medical need.

Pulmonary fibrosis (PF) is a life-threatening disorder with a very poor prognosis. Because of the complexity of PF pathological mechanisms, filling such an unmet medical need is challenging. A number of pulmonary diseases have been linked to the activation of NF-κB and the NLRP3 inflammasome.

AKT-AMPKα-mTOR-dependent HIF-1α Activation is a New Therapeutic Target for Cancer Treatment: A Novel Approach to Repositioning the Antidiabetic Drug Sitagliptin for the Management of Hepatocellular Carcinoma.

HIF-1α is a key factor promoting the development of hepatocellular carcinoma (HCC). As well, AKT-AMPKα-mTOR signaling is a promising target for cancer therapy. Yet, the AKT-AMPKα-mTOR-dependent activation of HIF-1α has not been studied in livers with HCC.

The dynamic interplay between AMPK/NFκB signaling and NLRP3 is a new therapeutic target in inflammation: Emerging role of dapagliflozin in overcoming lipopolysaccharide-mediated lung injury.

Acute lung injury (ALI) is one the most common causes of morbidity and mortality in critically ill patients. In this study, we examined for first time the role of dapagliflozin (DPGZ) in lipopolysaccharide (LPS)-induced ALI in rats and determined the underlying molecular mechanisms by evaluating the effects of DPGZ on adenosine monophosphate kinase (AMPK), nuclear transcription factor kappa B, nucleotide-binding and oligomerization domain-like receptor 3 inflammasome activation. Treatment of acute lung injured rats with either low dose (5 mg/kg) or high dose (10 mg/kg) DPGZ significantly decreased oxidative stress by decreasing malondialdehyde and nitric oxide tissue levels with a significant increase in spectrophotometric measurements of superoxide dismutase, catalase, and reduced glutathione levels.
