Polyprenylated xanthones with potential anti-inflammatory and anti-HIV effects from the stems and leaves of (Lour.) Blume.

A phytochemical study on the stems and leaves of (Lour.) Blume resulted in the isolation and characterisation of a new polyprenylated xanthone, cratocochinone (), as well as seven known analogues, fuscaxanthone K (), pruniflorone Q (), 1,3,5,8-tetrahy-droxy- 2-(3-methybut-2-enyl)-4-(3,7-dimethylocta-2,6-dienyl) xanthone (), cochinensoxanthone (), cratoxylum-xanthone B (), cochinchinone I () and cochinchinone K (). The chemical structure of was determined by comprehensive spectral analyses.

Translatomics reveals the role of dietary calcium addition in regulating muscle fat deposition in pigs.

Intramuscular fat (IMF) in pork holds significant importance for economic performance within the pig industry and dietary calcium supplementation enhances the accumulation of intramuscular fat. Additionally, calcium ions inhibit translation and reduce protein synthesis. However, the mechanism by which calcium regulates IMF deposition in muscle through translation remains largely unknown.

The landscape of super-enhancer regulates remote target gene transcription through loop domains in adipose tissue of pig.

Background: A super-enhancer (SE) is a huge cluster of multiple enhancers that control the key genes for cell identity and function. The rise of advanced chromatin immunoprecipitation sequencing (ChIP-seq) technology such as Cleavage Under Targets and Tagmentation (CUT&Tag) allows more SEs to be discovered. However, SE studies in Luchuan and Duroc pigs are very rare in animal husbandry.

Deletion of the mitochondrial calcium uniporter in adipose tissue promotes energy expenditure and alleviates diet-induced obesity.

Objective: Studies have shown a correlation between obesity and mitochondrial calcium homeostasis, yet it is unclear whether and how Mcu regulates adipocyte lipid deposition. This study aims to provide new potential target for the treatment of obesity and related metabolic diseases, and to explore the function of Mcu in adipose tissue.

Methods: We firstly investigated the role of mitoxantrone, an Mcu inhibitor, in the regulation of glucose and lipid metabolism in mouse adipocytes (3T3-L1 cells).

Rhynchophylline relieves nonalcoholic fatty liver disease by activating lipase and increasing energy metabolism.

Hepatic fat metabolism may be altered in the context of overnutrition and obesity, often resulting in the accumulation of triglycerides in hepatocytes and leading to nonalcoholic fatty liver disease (NAFLD). Natural plant alkaloids have demonstrated great potential for the prevention and treatment of NAFLD. However, the role of rhynchophylline (RHY) in lipid metabolism is not clear.

Transcriptome-Wide Study Revealed That N6-Methyladenosine Participates in Regulation Meat Production in Goats.

In mammals, skeletal muscle development is a complex biological process regulated by many factors. N6-methyladenosine (m6A) RNA modification plays an important role in many biological processes. However, the regulation of m6A on skeletal muscle growth and development in adult goats remains unclear.

Hesperidin methyl chalcone ameliorates lipid metabolic disorders by activating lipase activity and increasing energy metabolism.

Obesity has become an increasingly serious health issue with the continuous improvement in living standards. Its prevalence has become an economic burden on health care systems worldwide. Flavonoids have been shown to be beneficial in the prevention and treatment of obesity.

The Roles of Natural Alkaloids and Polyphenols in Lipid Metabolism: Therapeutic Implications and Potential Targets in Metabolic Diseases.

The prevalence of obesity and its associated diseases has increased dramatically, and they are major threats to human health worldwide. A variety of approaches, such as physical training and drug therapy, can be used to reduce weight and reverse associated diseases; however, the efficacy and the prognosis are often unsatisfactory. It has been reported that natural food-based small molecules can prevent obesity and its associated diseases.

Small Intestine-specific Knockout of CIDEC Improves Obesity and Hepatic Steatosis by Inhibiting Synthesis of Phosphatidic Acid.

The small intestine is main site of exogenous lipid digestion and absorption, and it is important for lipid metabolic homeostasis. Cell death-inducing DNA fragmentation-factor like effector C (CIDEC) is active in lipid metabolism in tissues other than those in the intestine. We developed small intestine-specific CIDEC (SI-CIDEC) knockout C57BL/6J mice by Cre/LoxP recombination to investigate the effects of intestinal CIDEC on lipid metabolism.

Genome-Wide Analysis of Long Non-coding RNAs Involved in Nodule Senescence in .

Plant long non-coding RNAs (lncRNAs) are widely accepted to play crucial roles during diverse biological processes. In recent years, thousands of lncRNAs related to the establishment of symbiosis, root nodule organogenesis and nodule development have been identified in legumes. However, lncRNAs involved in nodule senescence have not been reported.

A New lncRNA, , Regulates Lipid Metabolism in Pig Hepatocytes.

A large variety of long noncoding RNAs (lncRNAs) have been discovered through high-throughput sequencing technology and some have been demonstrated to play important roles in lipid metabolism regulation. In our study, we found a highly expressed lncRNA ( liver lipid metabolism-associated lncRNA) in the liver of Duroc pigs, which was enriched in the nucleus. It displays potent tissue specificity among different pig breeds.

Translatomics Probes Into the Role of Lycopene on Improving Hepatic Steatosis Induced by High-Fat Diet.

Liver is an important organ for fat metabolism. Excessive intake of a high-fat/energy diet is a major cause of hepatic steatosis and its complications such as non-alcoholic fatty liver disease and non-alcoholic steatohepatitis. Supplementation with lycopene, a natural compound, is effective in lowering triglyceride levels in the liver, although the underlying mechanism at the translational level is unclear.

Translatome analysis reveals the regulatory role of betaine in high fat diet (HFD)-induced hepatic steatosis.

Non-alcoholic fatty liver disease (NAFLD) is a common disease with a multitude of complications. Increasing evidence shows that the dietary supplement with betaine, a natural chemical molecule, can effectively reduce the fat accumulation in the liver. Translational regulation is considered to play a vital role in gene expression, but whether betaine functions through the regulation of gene translational level is still unclear.
