Phenolic acids can improve obesity-related and metabolic syndrome-related conditions including non-alcoholic fatty liver disease (NAFLD). In this study, the effects of ferulic acid (FA) on the metabolic changes related to NAFLD were investigated in oleic acid (OA)-treated HepG2 cells and C57BL/6 mice fed a high fat diet (HFD). In vitro, FA (25 and 50 μg/mL) treatment significantly reduced cellular lipid accumulation with no obvious cytotoxicity, in-part mediated by the suppression of ERK1/2, JNK1/2/3, and HGMB1 expression. However, in vivo administration of FA (20 mg/kg bw·day) for 17 weeks led to no obvious effects on body weight and liver weight gain, blood lipid profiles, or histological abnormalities in obese C57BL/6 mice induced by HFD. Taken together, the positive effects of FA on the reduction of hepatic triglyceride accumulation were therefore demonstrated in cellular model, while its hepatic protective effects might need to be further explored in rodent models and clinical trials.

Autism spectrum disorder (ASD) is linked to ion channel dysfunction, including chloride voltage-gated channel-4 (CLCN4). We generated Clcn4 knockout (KO) mice by deleting exon 5 of chromosome 7 in the C57BL/6 mice. Clcn4 KO exhibited reduced social interaction and increased repetitive behaviors assessed using three-chamber and marble burying tests.

How macrophages in the tissue environment integrate multiple stimuli depends on the genetic background of the host, but this is still poorly understood. We investigate IL-4 activation of male C57BL/6 and BALB/c strain specific in vivo tissue-resident macrophages (TRMs) from the peritoneal cavity. C57BL/6 TRMs are more transcriptionally responsive to IL-4 stimulation, with induced genes associated with more super enhancers, induced enhancers, and topologically associating domains (TAD) boundaries.

Mice models serve as a valuable tool to study microbiome-immune system interactions. While the use of germ-free mice may represent the gold-standard method, antibiotic-based microbiome depletion provides a more cost-efficient and feasible system. The protocol here in presented provides a mild antimicrobial regime to deplete basal microbiota in 8-week-old C57BL/6 mice, aiming to ensure reproducibility in microbiota studies.

Oxidative stress induced by excess ethanol is an important factor in the progression of alcoholic liver disease (ALD). In recent years, inhibiting Kelch-like ECH-associated protein 1 (KEAP1) to activate the antioxidant regulator Nuclear factor erythroid 2-related factor 2 (NRF2) has been considered an effective strategy for treating oxidative stress-related diseases, but its application in ALD remains insufficiently explored. This study aims to discover high-affinity inhibitors targeting the KEAP1 receptor.
