| Elevated free fatty acid uptake via CD36 promotes epithelial-mesenchymal transition in hepatocellular carcinoma. | Hepatocellular carcinoma (HCC) is the second-leading cause of cancer-related death worldwide, and the factors influencing HCC progression are poorly understood. Here we reveal that HCC progression via induction of epithelial-mesenchymal transition (EMT) is closely associated with the expression of CD36/fatty acid translocase and elevated free fatty acid (FFA) levels. Although obesity is manifested as elevated FFA levels, the degree of EMT was not associated with the body mass index of the patients, highlighting the specific roles of CD36 and FFA uptake. Treatment of human liver cancer cell lines with FFAs exacerbated the EMT phenotype, whereas chemical inhibition of CD36 mitigated these effects. Furthermore, the Wnt and TGF-beta signaling pathways were activated upon FFA treatment, potentially acting as upstream activators of the EMT program. These results provide the first direct evidence associating CD36 and elevated FFAs with HCC progression. |
| CD36 is involved in high glucose-induced epithelial to mesenchymal transition in renal tubular epithelial cells. | The epithelial-to-mesenchymal transition (EMT) plays an important role in the progression of diabetic nephropathy. Our recent study showed that ROS mediated high glucose (HG)-induced EMT in renal tubular epithelial cells. CD36, a class-B scavenger receptor, has been reported to mediate the production of ROS in chronic kidney disease. In the present study, we examined the effect of inhibition of CD36 with CD36 siRNA or sulfosuccinimidyl-oleate (SSO), a CD36 antagonist, on HG-induced EMT in HK-2 cells. HG induced CD36 expression in a time-dependent manner in HK-2 cells. HG was shown to induce EMT at 72 h. This was blocked by knockdown of CD36 or treatment with SSO. Meanwhile, we also found that knockdown of CD36 or treatment with SSO inhibited HG-induced ROS generation, activation of ERK1/2 and Smad2, expression of TGF-beta1 and synthesis of fibronectin. These data suggest that inhibition of CD36 prevented HG-induced EMT in HK-2 cells, highlighting CD36 as a potential therapeutic target for diabetic nephropathy.CI - Copyright (c) 2015 Elsevier Inc.
