Summary: Hypermetabolism following severe burn injuries can lead to adipocyte dysfunction and other adverse consequences, with adipose triglyceride lipase (ATGL) playing a crucial role in regulating these processes. Targeting ATGL may reduce adipose tissue changes and improve patient outcomes, as demonstrated by selective ATGL inhibitor studies.

Summary: Fasting and starvation have been significant environmental factors that have shaped human energy metabolism. Humans adapt to fasting through time-dependent changes in energy metabolism, including the breakdown of liver glycogen, muscle protein, and fat stores. This paper provides an overview of the effects of fasting on adipose tissue metabolism, including the inhibition of lipoprotein lipase activity and activation of adipose triglyceride lipase.

Summary: Bidirectional interactions between cancer cells and adipocytes in the microenvironment play a critical role in tumor progression. Acidification of the extracellular medium induced by cancer cells promotes preadipocyte lipolysis, which affects the phenotype of cancer cells and their response to chemotherapy. G0S2 is identified as the main regulator of cancer-induced lipolysis, and its adipocyte-specific overexpression inhibits mammary tumor growth and lung metastasis.

Summary: This study investigates the impact of Phillyrin on obesity-related metabolic dysfunctions. It was found that Phillyrin reduces circulating level of glycerol, hepatic steatosis, and improves insulin sensitivity in obese mice. Phillyrin also attenuates obesity-related inflammation and IL-6 production in adipose tissue. Furthermore, Phillyrin inhibits IL-6-initiated basal lipolysis and expression of adipose triglyceride lipase (ATGL) in adipose tissue. These findings suggest that Phillyrin can be a potential candidate in the treatment of obesity-associated complications.

Summary: Two distinct diacylglycerol acyltransferases (DGAT1 and DGAT2) catalyze the final step of TG synthesis in hepatocytes. TG is either stored in cytosolic LDs or assembled into VLDLs in the ER. DGAT1-made TG is stored in smaller LDs while DGAT2-made TG is stored in larger LDs. ATGL targets DGAT1-generated LDs and the fatty acids released from these LDs are preferentially used for oxidation.

Summary: Deleting the Pin1 gene in epiWAT promotes lipolysis and increases ATGL protein expression. Pin1 directly associates with ATGL, enhancing its degradation through the ubiquitin proteasome system. AdipoPin1 KO mice under a high fat diet exhibit higher lipolytic activity and improved glucose metabolism.

Summary: There is an inverse relationship between the differentiation of MSCs along adipocyte or osteoblast lineages mediated by PPAR gamma and Runx2. HSL knockout in mice improved fracture repair and enhanced MSC differentiation and recruitment, while inhibiting HSL. This study highlights the potential role of HSL in bone injury repair and the importance of pre-osteoclasts and osteoclasts.

Summary: Elevated levels of adipose triglyceride lipase (ATGL) in colorectal cancer patients are associated with advanced clinical stages and poor overall survival. ATGL promotes cell proliferation and inhibits apoptosis in CRC cells. Mechanistically, ATGL enhances the carcinogenic function of CRC cells by promoting lipid metabolism and CoA biosynthesis pathway. This study highlights ATGL as a novel oncogene in CRC with potential as a prognostic factor and therapeutic target.

Summary: This study investigated the gut microbiota characteristics in 120 pigs of different breeds, growth periods, and genders, revealing that gut microbiota plays important roles in nutrition, metabolism, and immunity. The top 10 most abundant genera accounted for 66.53% of the microbiota, and 28 common species were identified. The explanatory effects of influencing factors suggested that growth period was the greatest contributor to the gut microbiota in pigs.

This study aimed to build a mouse model infected with porcine C. perfringens and investigated its effects on growth performance, immune status, and intestinal integrity in mice. The results showed that high dose of C. perfringens caused a decline in growth performance, severe damage to intestinal structure, and increased inflammation in mice.

Summary: This study found that exposure to BDE-47 can cause ovarian lipid deposition and hormone disruption accompanied by oxidative stress and downregulation of hormone biosynthesis-related proteins. Using a cellular model, it was shown that BDE-47 inhibits ovarian hormone secretion by interfering with specific pathways and inducing endoplasmic reticulum stress, mitochondrial abnormalities, and lipotoxicity. The findings suggest potential health risks of BDE-47 pollution areas to women, particularly affecting their ovarian hormone secretion.

Summary: Skeletal muscle is crucial in human biological activities and energy homeostasis, as well as meat production and quality in animals. Adipose tissue, particularly white and brown adipose tissue, acts not only as an energy reserve but also as an endocrine organ that secretes signaling molecules known as adipokines and lipokines. This review highlights the secretory role of adipose tissues and the regulatory effects of adipokines and lipokines on skeletal muscle development and homeostasis. It also suggests the potential use of these molecules as drug candidates for treating muscle dysfunction and metabolic diseases, as well as their role as promising nutrients for improving animal production.

Summary: This study investigated the effects of acute cold exposure on lipid metabolism and transcriptomic changes in mouse skeletal muscle. The results showed that cold exposure led to increased intramuscular fat deposition, altered lipid composition, and upregulated genes involved in lipolysis and fatty acid biosynthesis. Cold-mediated mitophagy may play a critical role in modulating lipid metabolism in skeletal muscle, which is regulated by HIF-1 alpha signaling.

Summary: This study investigated the cellular and transcriptional mechanisms underlying lipid deposition in highly-marbled pork using single-nucleus RNA sequencing and bulk RNA sequencing. The results revealed that the high marbled group had higher intramuscular fat (IMF) contents and lower drip loss compared to the low marbled group. Single-nucleus RNA sequencing showed a higher percentage of adipocytes in the high marbled group. Additionally, bulk RNA sequencing identified different genes involved in lipid metabolism and fatty acid elongation. The findings provide new insights into the cellular and molecular signatures of marbling formation in pork.
