Project description:DY131 is a pharmacological agonist of the orphan receptor estrogen-related receptor (ERR) γ which plays a crucial role in regulating energy generation, oxidative metabolism, cell apoptosis, inflammatory responses, etc. However, its role in acute liver injury is unknown. In the study, we evaluated the effect of DY131 on lipopolysaccharide (LPS)-induced liver injury. Transcriptomics analysis revealed that the dysregulated pathways associated with inflammation and metabolism were significantly reversed by DY131 in LPS-treated mice, providing more evidence in favor of the protective effect of DY131 against LPS-induced liver injury.

Project description:Sepsis-associated liver dysfunction remains a challenge in clinical practice with high mortality and limited specific therapies. DY131 is a pharmacological agonist of the orphan receptor estrogen-related receptor (ERR) γ which plays a crucial role in regulating energy generation, oxidative metabolism, cell apoptosis, inflammatory responses, etc. However, its role in acute liver injury is unknown. In this study, we evaluated the effect of DY131 on lipopolysaccharide (LPS)-induced liver injury. Mice were pretreated with DY131 through intraperitoneal injection at a dose of 5 mg/kg/day for 3 days prior to LPS challenge (10 mg/kg). 24 h later, they were anesthetized and sacrificed. Blood and liver tissues were collected for further studies. In a separate experiment, mice were treated with saline (vehicle) or DY131 for 3 days to evaluate the toxicity of DY131. We found that ERRγ was downregulated in the liver tissues from LPS-treated mice. Pretreatment with DY131 ameliorated LPS-induced liver injury as demonstrated by reduced liver enzyme release (ALT, AST, and LDH), improved liver morphological damage, and attenuated oxidative stress, inflammation and apoptosis. Meanwhile, DY131 had no significant side effects on hepatic and renal functions in mice. Finally, transcriptomics analysis revealed that the dysregulated pathways associated with inflammation and metabolism were significantly reversed by DY131 in LPS-treated mice, providing more evidence in favor of the protective effect of DY131 against LPS-induced liver injury. Altogether, these findings highlighted the protective effect of DY131 on LPS-induced hepatotoxicity possibly via suppressing oxidative stress, inflammation, and apoptosis.

Identification of an alternative ligand binding pocket in PPAR-γ and its corelated selective agonist for promoting beige adipocyte differentiation

Project description:Pharmacological activation of peroxisome proliferator-activated receptor gamma (PPAR-γ) is a convenient and promising tactic for promoting beige adipocyte biogenesis to combat obesity-related metabolic disorders. However, thiazolidinediones (TZDs), the full agonist of PPAR-γ exhibits severe side effects in animal model and clinical uses. Therefore, it is emerging to develop efficient and safe PPAR-γ modulators for metabolic disease treatment. Here, by utilizing comprehensive methods, we report a previously unidentified ligand binding pocket (LBP) in PPAR-γ and link it to beige adipocyte differentiation. Further virtual screening from 4097 natural compounds based on this novel LBP, we discover NJT-2, a terpenoid compound, can bind to PPAR-γ induce co-activator recruitment and effectively activate PPAR-γ mediated transcription of beige adipocyte program. Importantly, in mouse model, NJT-2 administration efficiently promotes beige adipocyte biogenesis and improve obesity-associated metabolic dysfunction with significant lower adverse effects than those observed in TZD. Our results not only provide an advanced molecular insight into the structural ligand binding details in PPARg, but also develop its linked selective and safe agonist for obesity treatment.

RNA Sequencing in LXR agonist fed Atp7b-/- mice (Wilson disease)

Project description:The goal of the study was find the gene expression of diverse signaling pathways altered in Atp7b-/- mice (murine WD) liver as compared to control mice and how LXR agonist treatment will improve/ameliorate WD phenotype in Atp7b-/- mice. Activation of LXR/RXR using synthetic LXR agonist ameliorates liver inflammation and fibrosis in murine WD by changing gene expression.
