Studies have shown that satins and herbal products have potential to treat non-alcohol fatty liver disease (NAFLD) in clinic. However, no study has compared their effects, and their mechanisms remain unresolved. Here, we choose lovastatin and two herbal products including berberine and curcumin to compare their effects in treating NAFLD. NAFLD model was established by high fat food, and rats were administrated with lovastatin, berberine, curcumin, berberine + curcumin at the dosage of 100, 100, 100, 50 + 50 mg/kg bw, respectively...

Liver transplantation is a therapeutic regimen to treat patients with non-malignant end-stage liver diseases and malignant tumors of hepatic origin. The ischemia/reperfusion (I/R) injury in liver transplantation is associated with disruption of mitochondrial function in the hepatic parenchyma. Several studies have been conducted in animal models to identify pharmacological therapeutic strategies to minimize the injury induced by the cold/warm I/R in liver transplantation. Most of these studies were conducted in unrealistic conditions without the potential to be translated to clinical usage...

BACKGROUND: Berberine, an alkaloid with both glucose- and cholesterol-lowering action, is also characterized by an anti-diarrheal effect. Consequently, berberine-based therapies are recommended for diabetic patients with irritable bowel syndrome (IBS) or gut discomfort caused by metformin. AIM: As the anti-glycemic and cholesterol-lowering action of berberine is improved by co-administration with P-glycoprotein inhibitors and naturally derived statins, we have analyzed the effect of the food supplement Berberol®K (hereafter referred to as BSM) containing, berberine, silymarin, and a highly standardized red yeast rice containing monacolins K and KA in the ratio 1:1 but no secondary monacolins, dehydromonacolins, or citrinin (Monakopure™-K20)...

Berberine (BBR) is an isoquinoline alkaloid derived from various medicinal herbs. Previous studies have suggested that BBR exerts antimicrobial, antitumor, and antidiabetic effects and can be used to treat Helicobacter pylori-induced chronic gastritis. However, the exact mechanism by which BBR inhibits H. pylori infection is not fully understood. We investigated the anti-inflammatory properties and potential mechanism of BBR in H. pylori-infected mice with chronic gastritis. We found that BBR can suppress the expression of pro-inflammatory genes IL-6, TGF-β, and IL-1β and upregulate anti-inflammatory gene IL-10 expression in the mucosa and RAW 264...

Aging is the greatest risk factor for human diseases, as it results in cellular growth arrest, impaired tissue function and metabolism, ultimately impacting life span. Two different mechanisms are thought to be primary causes of aging. One is cumulative DNA damage induced by a perpetuating cycle of oxidative stress; the other is nutrient-sensing adenosine monophosphate-activated protein kinase (AMPK) and rapamycin (mTOR)/ ribosomal protein S6 (rpS6) pathways. As the main bioactive component of natural Chinese medicine rhizoma coptidis (RC), berberine has recently been reported to expand life span in Drosophila melanogaster, and attenuate premature cellular senescence...

Fibroblast growth factor 21 (FGF21), a hormone-like protein mainly derived from liver, exhibits multiple beneficial effect on energy metabolism. Similar to FGF21, berberine exerts anti-hyperglycemic and anti-dyslipidemic properties. Previous studies revealed that the beneficial metabolic effect of berberine was attributed to the activation of AMP-activated protein kinase (AMPK). Here we investigated the effect of berberine on FGF21 expression in primary mouse hepatocytes. As expected, berberine induced hepatic FGF21 expression in a dose-dependent and time-dependent manner, along with the increased expression of NUR77, a proved transcription factor of FGF21...
