We show that TR4 facilitates lipid accumulation in 3T3-L1 adipocytes via induction of the FATP1 gene. Further study showed that TR4 transactivated FATP1 5' promoter activity via direct binding to the TR4 responsive element located at the FATP1 5' promoter region. Constitutive overexpression of TR4 in 3T3-L1 adipocytes resulted in increased lipid accumulation, accompanied by an increase in fatty acid uptake. However, small interfering RNA knockdown of FATP1 abolished TR4-enhanced fatty acid uptake. Moreover, microRNA-mediated silencing of TR4 in 3T3-L1 adipocytes drastically reduced basal FATP1 5' promoter activity and FATP1 expression with reduced lipid accumulation.

Silkworms are emerging as a sustainable food source to address global food security, with their proteins recognized for nutritional and medicinal benefits. However, the impact of silkworm oil on immunological and pharmacological effects remains unexplored. This study explores the effects of the muga (Antheraea assamensis Helfer) silkworm pupal oil fraction (MP) on palmitic acid (PA) induced hepatic steatosis, inflammation, and oxidative stress.

Background/aims: Endoplasmic reticulum (ER) stress in hepatocytes plays a causative role in alcohol-associated liver disease (ALD). The incomplete inhibition of ER stress by targeting canonical ER stress sensor proteins suggests the existence of noncanonical ER stress pathways in ALD pathology. This study aimed to delineate the role of RAB25 in ALD and its regulatory mechanism in noncanonical ER stress pathways.

Lipid metabolism plays an important role in aging and longevity, and lipophagy-a specialized form of autophagy that targets lipid vesicles-regulates lipid homeostasis and alleviates metabolic diseases such as metabolic dysfunctionassociated steatotic liver disease (MASLD). Ilimaquinone (IQ), a sesquiterpene extracted from the sea, is well-known for its various biological effects; however, its effects on lipid metabolism and longevity have not yet been elucidated. In this study, IQ acted in a dose-dependent manner, extending the lifespan of Caenorhabditis elegans (C.

Objectives: To investigate the therapeutic effect of electroacupuncture (EA) at Zusanli (ST36) acupoint on hyperlipidemia in mice and explore the underlying mechanisms.
Methods: Thirty C57BL/6J mice were equally randomized into normal diet group, high-fat diet (HFD) group, and EA group. The changes in blood lipids and serum malondialdehyde (MDA) content of the mice were evaluated, and histopathological changes and lipid accumulation in the liver were observed using Oil red O staining (ORO).
