Objective: To explore the effects of berberine and insulin on adiponectin mRNA expression in 3T3-L1 adipocyte.
Method: The 3T3-L1 adipocyte was treated with berberine and insulin for 48 hours, the level of adiponectin mRNA in 3T3-L1 adipocyte expression was determined with semiquantity RT-PCR using beta-actin as internal reference.
Result: The level of adiponetin mRNA in 3T3-L1 adipocyte was increased after treated with berberine only (P < 0.05), the effect of berberine was inhibited by high concentration insulin (P < 0.05).
Conclusion: In vitro, berberine increases the expression of adiponectin in 3T3-L1 adipocyte, insulin inhibits the effect of berberine.

This study was conducted to investigate the anti-obesity effects of bioactive fractions JAF2 and JAF3 from Justicia adhatoda (JA) in vitro using enzymatic assays, 3T3-L1 cells and in vivo using a monosodium glutamate-high-fat diet (MSG-HFD) model. High-Performance Thin Layer Chromatography coupled with Mass Spectrometry (HPTLC-MS-MSn) was finally utilized to analyze bioactive fractions for the compounds responsible for the activity. In vitro, the anti-obesity effects of JAF2 and JAF3 were assessed in 3T3-L1 adipocytes, revealing that JAF2 significantly reduced lipid and triglyceride levels.

Obesity, a major risk factor for various metabolic diseases, often results in dysfunctional white adipose tissue and altered adipogenesis leading to ectopic fat accumulation, inflammation, and insulin resistance. On the other hand, cashew (Anacardium occidentale L.) nut worldwide consumption and production is increasing steadily, which augments the mass of byproducts to be discarded.

Non-dioxin-like polychlorinated biphenyls (NDL-PCBs), as well as dioxin-like PCBs, are endocrine disruptors that persist in human and animal tissues worldwide. Due to their lipophilicity and resistance to enzymatic degradation, PCBs accumulate in fat deposits contributing to the onset of endocrine and metabolic diseases. Aquaporins (AQPs) are transmembrane channel proteins that allow the transport of water and small solutes.

Introduction: Berberine (BBR) has the characteristics of repressing hyperglycemia, obesity, and inflammation, as well as improving insulin resistance. However, the underlying mechanism remains to be fully understood. This study explores whether BBR regulates inositol requiring enzyme 1 (IRE1)/glycogen synthase kinase 3 beta (GSK-3β) axis to resist obesity-associated inflammation, thereby improving glucolipid metabolism disorders.

Chlorinated paraffins (CPs) are environmental pollutants extensively used in industries. While the use of short-chain chlorinated paraffins (SCCPs) has been restricted since 2017, the use of medium-chain chlorinated paraffins (MCCPs) has risen as their replacement. Due to lipophilic character, it can be expected that CPs enter the cells; however, the in vitro accumulation potential of CPs remains poorly understood.
