RPEP-05471 · 2021AWRK6 (novel GLP-1R agonist from frog AMP) alleviated obesity and hepatic steatosis in HED-induced MAFLD mice, improved lipid and glucose metabolism, and activated PI3K/AKT/AMPK/ACC signaling. Confirmed in human HepG2 fatty liver cell model.

RPEP-09087 · 2024PPAR agonists work by making cells more sensitive to insulin. Pioglitazone (a PPARγ agonist) and saroglitazar (a PPARα/γ agonist) are recommended by several medical groups for treating fatty liver in diabetes. Newer PPAR drugs like elafibranor and lanifibranor are also showing promise.
GLP-1 receptor agonists take a different approach. They produce significant weight loss and may directly reduce liver inflammation and fibrosis (scarring). The review notes that dual-agonists (like tirzepatide targeting GIP/GLP-1) and triple-agonists have produced even more impressive weight loss, which could further benefit the liver. However, direct evidence of liver benefit from these newer multi-agonists is still limited.

RPEP-09099 · 2024The researchers created a microphysiological system (MPS), a tiny interconnected network of human fat cells, liver cells, and inflammatory immune cells (macrophages). When macrophages inflamed the fat cells, the liver cells accumulated fat and stopped responding to insulin properly. This recreated the early stages of metabolic dysfunction-associated steatotic liver disease (MASLD, previously called NAFLD).
Semaglutide improved liver cell function in this system. The key discovery: semaglutide acted on the fat cells, not the liver cells. By calming the inflamed fat cells, semaglutide indirectly reduced liver fat accumulation and restored insulin sensitivity throughout the system.

RPEP-09141 · 2024High-fat diet versus control: liver triglycerides increased 82%, steatosis increased 850%, glucose intolerance increased 71%, insulin increased 98%, and insulin resistance increased 68%.
Both drug combinations improved all parameters compared to untreated obese mice:
- Empagliflozin + linagliptin: glucose intolerance -60%, insulin -61%, insulin resistance -46%, TAG -61%, steatosis -58%
- Empagliflozin + dulaglutide: glucose intolerance -71%, insulin -58%, insulin resistance -62%, TAG -61%, steatosis -82%
Principal component analysis clearly separated the groups: the GLP-1 combination was furthest from the disease group, while the DPP-4 combination fell between control and the GLP-1 group.

RPEP-09205 · 2024Survodutide achieved MASH improvement without fibrosis worsening in 47% (2.4 mg), 62% (4.8 mg), and 43% (6.0 mg) of participants vs 14% on placebo (P<0.001). Liver fat reduction ≥30% occurred in 57-67% of survodutide groups vs 14% placebo. Fibrosis improved by ≥1 stage in 34-36% vs 22% placebo.

RPEP-09216 · 2024Switching from dulaglutide to tirzepatide produced average reductions of 1.2% in HbA1c and 3.6 kg in body weight at 6 months. Liver enzymes (AST, ALT, GGT) significantly decreased. HbA1c reduction correlated with higher baseline HbA1c, while weight loss was baseline-independent. Fibrosis-4 index trended toward improvement in those with higher baseline values.
