| Study Title | The Carbohydrate Sensing Transcription Factor ChREBP Links Mitochondrial Lipidomes to Mitochondrial Dynamics and Progression of Diabetic Nephropathy |
| Study Type | Biomarker |
| Study Summary | Despite recent advances, diabetic nephropathy (DN) remains a major public health concern. The precise underlying molecular mechanisms of DN remain elusive. Accumulating recent evidence suggests that mitochondrial integrity and lipid metabolism in podocytes significantly contribute to the pathogenesis of DN. However, the interplay between these two key metabolic regulators of DN is not fully understood. This study examines the role of ChREBP (carbohydrate-response element-binding protein), a master regulator of lipogenesis, on mitochondrial morphology and progression of DN. Our findings suggest that diabetic mice with podocyte-specific deletion of ChREBP are protected against mitochondrial fragmentation and progression of DN. Using liquid chromatography coupled with mass spectrometry, we identified the central role of ChREBP-induced plasmalogen phospholipids in linking mitochondrial lipidomes with mitochondrial dynamics in DN. |

| Collection ID: | CO002223 |
| Collection Summary: | Conditionally immortalized mouse podocytes were cultured as previously reported.25, 35 Podocytes were treated with 20μM of DL-α-palmitin (Sigma-Aldrich), 1-O-Hexadecyl-rac-glycerol (16:0-AG, Santa Cruz) ,1-O-Octadecyl-rac-glycerol (18:0-AG, Sigma-Aldrich) or 0.05% ethanol (vehicle) for 48 hours. An engineered miR-30 based ChREBP knockdown (KD) construct was assembled by PCR using previously validated ChREBP shRNA clone,34 followed by an optimized miR-E backbone. Stable podocyte cell line with ChREBP KD were generated by transfection into constructs together with PiggyBac transposase. After selection with 0.5 μg/ml of blasticidin alone or in combination with 1μg/ml puromycin, GFP-positive cells were sorted by FACS, and the top 30% population were collected. |
