p53 expression and glutamate secretion in OS cells. (A) Western blots showing expression of p53 in OS cell lines and PDX cells. The data was analyzed by one-way ANOVA followed by Dunnett’s test. *p<0.05. (B–D) Glutamate secreted into media between days 0 and 7 by primary OS cell lines, hFOB and metastatic cell lines, and hFOB and PDX cells. The experiment was repeated three times; the average of the three is shown. The data was analyzed by one-way ANOVA followed by Dunnett’s test for each day, with the value for hFOB for that day serving as the comparison value. *p <0.05, **p<0.01, ***p<0.001. (E–F) mRNA expression of mGluR1 and <t>mGluR5</t> by OS cell lines, measured by quantitative PCR. *p<0.05, **p<0.01, ***p<0.001.

Schematic diagram summarizing the underlying mechanism by which metabotropic glutamate receptor type 5 alleviates hepatic steatosis. Metabotropic glutamate receptor type 5 inhibition promotes AMPK phosphorylation, which leads to increased LC3II expression and nuclear translocation of transcription factor EB and the induction of p62 transcription, thereby activating autophagy and reducing lipid accumulation in hepatocytes. mGluR5: Metabotropic glutamate receptor type 5; TFEB: Transcription factor EB.

doi: 10.3748/wjg.v31.i7.98852

Figure Lengend Snippet: Schematic diagram summarizing the underlying mechanism by which metabotropic glutamate receptor type 5 alleviates hepatic steatosis. Metabotropic glutamate receptor type 5 inhibition promotes AMPK phosphorylation, which leads to increased LC3II expression and nuclear translocation of transcription factor EB and the induction of p62 transcription, thereby activating autophagy and reducing lipid accumulation in hepatocytes. mGluR5: Metabotropic glutamate receptor type 5; TFEB: Transcription factor EB.

Techniques: Inhibition, Expressing, Translocation Assay
