Visfatin-induced upregulation of lipogenesis via EGFR/AKT/GSK3 β pathway promotes breast cancer cell growth
Cell Signal. 2023 Apr 19:110686. doi: 10.1016/j.cellsig.2023.110686. Online ahead of print.ABSTRACTBreast cancer (BC) incidence and associated mortality have increased in tandem with the growth in obesity among the females worldwide. An adipokine, visfatin, has been shown to potentially impact glucose, lipid, and protein metabolism, and promote cancer growth however, the mechanism underlying the effect of visfatin on lipid metabolism dysregulation contributing to BC cell survival, proliferation, and metastasis has not been elucidated. Herein, we have investigated the role of visfatin on the induction of Sterol regulatory e...

Abietic acid alleviates endoplasmic reticulum stress and lipid accumulation in human primary hepatocytes through the AMPK/ORP150 signaling
This study investigated the impacts of AA on ER stress and steatosis in in vitro obesity models. We found that Treatment with AA reduced lipid deposition and lipogenesis-related proteins expression in human primary hepatocytes. Augmented expression of ER stress markers (phospho-eukaryotic initiation factor-2α (eIF2α) and C/EBP homologous protein (CHOP)) in palmitate-treated hepatocytes were reversed by AA treatment. Further, AA treatment increased the expression of phospho-AMPK and oxygen-regulated protein 150 (ORP150) in hepatocytes. siRNA-associated knockdown of AMPK or ORP150 expression reduced the effects of AA on no...

Silencing of RSPO1 mitigates obesity-related renal fibrosis in mice by deactivating Wnt/ β-catenin pathway
Exp Cell Res. 2021 Jun 25:112713. doi: 10.1016/j.yexcr.2021.112713. Online ahead of print.ABSTRACTObesity, a global epidemic, is one of the critical causes of chronic kidney disease (CKD). R-spondin1 (RSPO1) possessing the potential to activate Wnt/β-catenin pathway was reported to be elevated in circulation of obesity objects. However, the function of RSPO1 and the latent mechanism in obesity-related CKD are still left to be revealed. In the present study, renal RSPO1 expression was increased in mice fed on high-fat diet (HFD) for 12 weeks. Lentivirus-mediated RSPO1 knockdown partly recovered obesity-related metabolic sy...

Fat mass and obesity-associated protein regulates lipogenesis via m6 A modification in fatty acid synthase mRNA.
This study provides novel insights into a unique RNA epigenetic mechanism by which FTO mediates hepatic lipid accumulation through m6 A modification and indicates that FTO could be a potential target for obesity-related diseases and cancer.

JUP/plakoglobin is regulated by salt-inducible kinase 2, and is required for insulin-induced signalling and glucose uptake in adipocytes.
CONCLUSIONS: These findings identify JUP as a novel player in the regulation of insulin sensitivity in adipocytes, and suggest that changes in JUP expression could contribute to the effect of SIK2 on insulin signalling in these cells. PMID: 32966883 [PubMed - as supplied by publisher]

Parabrachial Interleukin-6 Reduces Body Weight and Food Intake and Increases Thermogenesis to Regulate Energy Metabolism
Publication date: 12 March 2019Source: Cell Reports, Volume 26, Issue 11Author(s): Devesh Mishra, Jennifer E. Richard, Ivana Maric, Begona Porteiro, Martin Häring, Sander Kooijman, Saliha Musovic, Kim Eerola, Lorena López-Ferreras, Eduard Peris, Katarzyna Grycel, Olesya T. Shevchouk, Peter Micallef, Charlotta S. Olofsson, Ingrid Wernstedt Asterholm, Harvey J. Grill, Ruben Nogueiras, Karolina P. SkibickaSummaryChronic low-grade inflammation and increased serum levels of the cytokine IL-6 accompany obesity. For brain-produced IL-6, the mechanisms by which it controls energy balance and its role in obesity remain unclear. H...

Thyroid hormone (T3) stimulates brown adipose tissue activation via mitochondrial biogenesis and MTOR-mediated mitophagy.
Abstract The thyroid hormone triiodothyronine (T3) activates thermogenesis by uncoupling electron transport from ATP synthesis in brown adipose tissue (BAT) mitochondria. Although T3 can induce thermogenesis by sympathetic innervation, little is known about its cell autonomous effects on BAT mitochondria. We thus examined effects of T3 on mitochondrial activity, autophagy, and metabolism in primary brown adipocytes and BAT and found that T3 increased fatty acid oxidation and mitochondrial respiration as well as autophagic flux, mitophagy, and mitochondrial biogenesis. Interestingly, there was no significant induct...

Palmitate Activates CCL4 Expression in Human Monocytic Cells via TLR4/MyD88 Dependent Activation of NF- κB/MAPK/ PI3K Signaling Systems
Conclusion: Collectively, our results show that palmitate induces CCL4 expression via activation of the TLR4-MyD88/NF-kB/MAPK/ PI3K signaling cascade. Thus, our findings suggest that the palmitate-induced CCL4 production might be an underlying mechanism of metabolic inflammation.Cell Physiol Biochem 2018;46:953 –964
