Analysis of deregulated genes upon Septin9 depletion in C2C12 and primary isolated myoblasts

Project description:Controlled myogenic differentiation is integral to the development, maintenance and repair of skeletal muscle, necessitating precise regulation of myogenic progenitors and resident stem cells. The transformation of proliferative muscle progenitors into multinuclear syncytia involves intricate cellular processes driven by cytoskeletal reorganization. While actin and microtubles have been extensively studied, we illuminate the role of septins, an essential yet still often overlooked cytoskeletal component, in myoblast architecture. Notably, Septin9 emerges as a critical regulator of myoblast differentiation during the initial commitment phase. Knock-down of Septin9 in C2C12 cells and primary mouse myoblasts accelerates the transition from proliferation to committed progenitor transcriptional programs. Furthermore, we unveil significant reorganization and downregulation of Septin9 during myogenic differentiation. Collectively, we propose that filmamentous septin structures and their orchestrated reorganization in myoblasts are part of a temporal regulatory mechanism governing the differentiation of myogenic progenitors. This study sheds light on the dynamic interplay between cytoskeletal components underlying controlled myogenic differentiation.

Genome-wide DNA methylation sequencing in C2C12 myoblasts and myotubes

Project description:We show the application of 5mC antibody-based methylated DNA immunoprecipitation followed sequencing technology for high-through profiling of DNA methylation in mouse C2C12 myoblasts and myotubes. By analyzing the methylation status of immunoprecipitated DNA fragments, we generated genome-wide DNA methyaltion maps in mouse C2C12 myoblasts and myotubes. We find that DNA methylation levels in myoblasts at rDNA promter and coding regions are higher than that in myotubes but not changed in intergenic regions.

Differentially expressed genes in c2c12 myoblasts

Project description:Proteosome inhibitors such as bortezomib (BTZ) have been used to treat muscle wasting in animal models. However, direct effect of BTZ on skeletal muscle cells has not been reported. In the present study, our data showed that C2C12 cells exhibited a dose-dependent decrease in cell viability in response to increasing concentrations of BTZ. We used microarrays to detail the differentially expressed genes in c2c12 myoblasts with different culture conditions.

Comprehensive analysis of the proteome, phosphoproteome and N-linked sialylated glycoproteome of C2C12 myoblasts

Project description:C2C12 myoblast is a model that has been used extensively to study the process of skeletal muscle differentiation. Proteomics has advanced our understanding of skeletal muscle biology and the process of myogenesis. However, there is still no deep coverage of C2C12 myoblast proteome, which is important for the understanding of key drivers for the differentiation of skeletal muscle cells. Here, we conducted a multi-dimensional proteome profiling with TiSH strategy to get a comprehensive analysis of proteome, phosphoproteome and N-linked sialylated glycoproteome of C2C12 myoblasts. A total of 8313 protein groups were identified in C2C12 myoblasts, including 7827 protein groups from non-modified peptides, 3803 phosphoproteins and 977 formerly N-linked sialylated glycoproteins.
