Anti-obesity properties of a Sasa quelpaertensis extract in high-fat diet-induced obese mice.

This study explores the anti-obesity properties of a Sasa quelpaertensis leaf extract (SQE) in high-fat diet (HFD)-induced obese C57BL/6 mice and mature 3T3-L1 adipocytes. SQE administration with HFD for 70 d significantly decreased the body weight gain, adipose tissue weight, and serum total cholesterol and triglyceride levels in comparison with the HFD group. SQE administration also reduced the serum levels of glutamic oxaloacetic transaminase, glutamic pyruvic transaminase and lactate dehydrogenase, and the accumulation of lipid droplets in the liver, suggesting a protective effect against HFD-induced hepatic steatosis.

Immature Citrus sunki peel extract exhibits antiobesity effects by β-oxidation and lipolysis in high-fat diet-induced obese mice.

The peel of Citrus sunki HORT. ex TANAKA has been widely used in traditional Asian medicine for the treatment of many diseases, including indigestion and bronchial asthma. In this study, we investigated the antiobesity activity of immature C.

Fucoxanthin exerts differing effects on 3T3-L1 cells according to differentiation stage and inhibits glucose uptake in mature adipocytes.

Progression of 3T3-L1 preadipocyte differentiation is divided into early (days 0-2, D0-D2), intermediate (days 2-4, D2-D4), and late stages (day 4 onwards, D4-). In this study, we investigated the effects of fucoxanthin, isolated from the edible brown seaweed Petalonia binghamiae, on adipogenesis during the three differentiation stages of 3T3-L1 preadipocytes. When fucoxanthin was applied during the early stage of differentiation (D0-D2), it promoted 3T3-L1 adipocyte differentiation, as evidenced by increased triglyceride accumulation.

A water-soluble extract of Petalonia binghamiae inhibits the expression of adipogenic regulators in 3T3-L1 preadipocytes and reduces adiposity and weight gain in rats fed a high-fat diet.

We previously showed that an ethanolic extract of the edible brown algae Petalonia binghamiae promotes the differentiation of 3T3-L1 preadipocytes and decreases hyperglycemia in streptozotocin-induced diabetic mice. Here, we report that a water-soluble extract of P. binghamiae thalli, prepared by enzymatic digestion, inhibits preadipocyte differentiation and adipogenesis in a dose-dependent manner.
