The JAK/STAT Pathway in Skeletal Muscle Pathophysiology
Conclusion and Perspectives The IL-6/JAK/STAT signaling cascade plays a dominant role in skeletal muscle pathophysiology. IL-6 autocrine, paracrine, and endocrine functions assign to its downstream effectors pivotal importance in skeletal muscle-wasting-associated diseases and other multiple system diseases where muscle acts in communication with other organs. Targeting the components of the JAK/STAT pathway recently emerged as a strategic approach for the treatment of inflammatory diseases and human cancer. This review highlights the opposite outcomes on muscle biology caused by the amount of local and systemic release ...

Genetic Regulation of Liver Metabolites and Transcripts Linking to Biochemical-Clinical Parameters
Conclusion In summary, this study is the first to combine metabolomics, transcriptomics, and genome-wide association studies in a porcine model. Our results improve understanding of the genetic regulation of metabolites which link to transcripts and finally biochemical-clinical parameters. Further, high-performance profiling of metabolites as intermediate phenotypes is a potentially powerful approach to uncover how genetic variation affects metabolic and health status. Our results advance knowledge in areas of biomedical and agricultural interest and identify potential correlates of biomarkers, SNPs-metabolites, SNPs-tran...

lncRNA ZEB1-AS1 Mediates Oxidative Low-Density Lipoprotein-Mediated Endothelial Cells Injury by Post-transcriptional Stabilization of NOD2
Conclusion We report the discovery that ZEB1-AS1 functionally participates in ox-LDL-induced ECs injury via LRPPRC-mediated stabilization of NOD2. Uncovering the precise role of ZEB1-AS1/LRPPRC/NOD2 pathway in the progression of ox-LDL-induced ECs death and AS will not only increase our knowledge of ox-LDL-induced AS, but also enable the development of novel therapeutic strategies to overcome oxidation product-induced diseases. Author Contributions XX and CL designed and mainly did the study. CM, ZD, and YD helped and did the study. Conflict of Interest Statement The authors declare that the research was conducted in ...

LncRNA MALAT1 is dysregulated in diabetic nephropathy and involved in high glucose ‐induced podocyte injury via its interplay with β‐catenin
In this study, we found that MALAT1 levels were increased in kidney cortices from C57BL/6 mice with streptozocin (STZ)‐induced diabetic nephropathy, and dynamically regulated in cultured mouse podocytes stimulated with high glucose, which showed a trend from rise to decline. The decline of MALAT1 levels was accompanied with β‐catenin translocation to the nuclei and enhanced expression of serine/arginine splicing factor 1 (SRSF1), a MALAT1 RNA‐binding protein. Further we showed early interference with MALAT1 siRNA partially restored podocytes function and prohibited β‐catenin nuclear accumulation and SRSF1 overexp...

Activation of autophagy flux by metformin downregulates cellular FLICE-like inhibitory protein and enhances TRAIL- induced apoptosis.
In this study, we demonstrated that metformin could induce TRAIL-mediated apoptotic cell death in TRAIL-resistant human lung adenocarcinoma A549 cells. Pretreatment of metformindownregulation of c-FLIP and markedly enhanced TRAIL-induced tumor cell death by dose-dependent manner. Treatment with metformin resulted in slight increase in the accumulation of microtubule-associated protein light chain LC3-II and significantly decreased the p62 protein levels by dose-dependent manner indicated that metformin induced autophagy flux activation in the lung cancer cells. Inhibition of autophagy flux using a specific inhibitor and ge...

Up-regulation of fatty acid synthase induced by EGFR/ERK activation promotes tumor growth in pancreatic cancer.
Abstract Lipid metabolism is dysregulated in many human diseases including atherosclerosis, type 2 diabetes and cancers. Fatty acid synthase (FASN), a key lipogenic enzyme involved in de novo lipid biosynthesis, is significantly upregulated in multiple types of human cancers and associates with tumor progression. However, limited data is available to understand underlying biological functions and clinical significance of overexpressed FASN in pancreatic ductal adenocarcinoma (PDAC). Here, upregulated FASN was more frequently observed in PDAC tissues compared with normal pancreas in a tissue microarray. Kaplan-Meie...

Long non‐coding RNA MALAT1 regulates hyperglycaemia induced inflammatory process in the endothelial cells
Abstract To examine whether the long non‐coding RNA (lncRNA) metastasis associated lung adenocarcinoma transcript 1 (MALAT1) is altered in the endothelial cells in response to glucose and the significance of such alteration. We incubated human umbilical vein endothelial cells with media containing various glucose levels. We found an increase in MALAT1 expression peaking after 12 hrs of incubation in high glucose. This increase was associated with parallel increase in serum amyloid antigen 3 (SAA3), an inflammatory ligand and target of MALAT1 and was further accompanied by increase in mRNAs and proteins of inflammatory m...
