Project description:SOX6 Gatekeeps Oligodendrocyte Maturation
| PRJNA809729 | ENA
Project description:Cellular maturation is an adaptive process essential for tissue formation and function, yet distinct from the initial steps of differentiation and cell fate specification. Understanding the regulation of cell maturation may inform underlying mechanisms of disease or new approaches to regenerative medicine. In the central nervous system, failed generation of mature oligodendrocytes contributes to numerous diseases including multiple sclerosis. Here, we report a transcriptional mechanism that governs the timing of oligodendrocyte maturation. After differentiation, the transcription factor SOX6 redistributes from super enhancers in proliferating oligodendrocyte progenitor cells to cluster across specific gene bodies in immature oligodendrocytes. These sites exhibit extensive chromatin decondensation and transcription, which abruptly turns off upon maturation. Suppression of SOX6 deactivates these immaturity loci, resulting in rapid transition to mature myelinating oligodendrocytes. Cells harboring this immature oligodendrocyte SOX6 gene signature are specifically enriched in multiple sclerosis patient brains, suggesting that failed maturation contributes to disease pathology. Administration of a Sox6-targeting antisense oligonucleotide in postnatal mice drove precocious oligodendrocyte maturation. Our findings reveal that SOX6 governs oligodendrocyte maturation and that its targeting could inform therapeutic strategies for enhancing myelin regeneration in neurodevelopmental and neurodegenerative diseases.

Project description:Rationale: We previously demonstrated that the transcription factor Sox6 regulates skeletal muscle biology by determining myofiber composition and muscle performance. Although the role of Sox6 and Sox5, its closest paralog, has not been ascertained in the heart, genome-wide association studies linked both Sox5 and Sox6 to cardiovascular disease. Objective: This study identifies the role of Sox5 and Sox6 in the adult mammalian heart under normal and stress conditions. Methods and Results: Using Sox5 and Sox6 cardiac-specific and Sox5 conduction system-specific knockout mice, we investigated the role of the two transcription factors in the heart under normal conditions and during cardiac stress. Sox5/6-deficient (DKO) mice displayed blunted cardiac contractility, which was present in Sox5 but not Sox6 single KO mice. DKO mice had a mild reduction in blood pressure, and conduction-specific knockout of Sox5 resulted in a reduced heart rate at baseline. After cardiac pressure overload, DKO mice showed increased lethality compared to control mice and were more prone to develop heart failure. We performed RNA deep sequencing in ventricles from DKO and control mice to identify potential Sox5/6 target genes and found altered expression of genes encoding regulators of calcium handling and cation transporters. Patch-clamping in isolated cardiomyocytes revealed shortened action potential duration in Sox5 KO cells. Conclusions: Unlike in skeletal muscle, our results suggest Sox5 but not Sox6 to be a major regulator of cardiac function and rhythm. Sox5 is essential to preserve cardiac function under normal conditions by maintaining contractility and to prevent cardiac failure after pressure overload.

Project description:The developmental transcription factor SOX6 was found to regulate serum, as well as liver triglycerides in BL6 mice treated with SOX6 antisense gapmers compared to control gapmers. SOX6 was initially discovered as a gene over-expressed in mesenchymal stem cells derived from small for gestational age newborns. We characterized its metabolic function in BL6 mice using the above antisense knockdown approach. BL6 mice were treated with either SOX6 specific or control gapmer oligonucleotides for 48h. Knockdown efficiency was measured in liver and epididymal white adipose tissues and serum levels of triglycerides and cholesterol quantified.
