Despite their relative rarity, satellite cells have critical functions in muscle adaptation, particularly during prolonged exercise training. The mechanisms by which satellite cells mediate skeletal muscle responsiveness to physical activity throughout the lifespan are still being defined, but epigenetic regulation may play a role. To explore this possibility, we analyzed global DNA methylation patterns in muscle tissue from female mice that engaged in lifelong voluntary unweighted wheel running with or without satellite cells. Satellite cells were ablated in adulthood using the tamoxifen-inducible Pax7-DTA model. Compared to sedentary mice, wheel running for 13 months caused muscle DNA methylation differences in the promoter regions of numerous muscle fiber-enriched genes—<i>Cacgn1</i>, <i>Dnm2</i>, <i>Mlip</i>, <i>Myl1</i>, <i>Myom2</i>, <i>Mstn</i>, <i>Sgca</i>, <i>Sgcg</i>, <i>Tnnc1</i>, <i>Tnni2</i>, <i>Tpm1</i>, and <i>Ttn</i>—only when satellite cells were present.

In this study, we investigated how the S1PR1/mitophagy axis modulates cementoblast mineralization and OIIRR progression. The in vivo orthodontic loading model revealed that heavy compression force triggered OIIRR and impaired cementoblast mineralization along with suppression of mitophagy in cementoblasts by downregulating PINK1 and PARKIN expression. The in vitro experiments further confirmed that heavy compression force increased reactive oxygen species (ROS) levels, disrupted mitochondrial membrane potential (MMP), and inhibited mitophagy in OCCM30 cells, thereby impairing their mineralization capacity.

Alternative splicing (AS) is a post-transcriptional process that generates multiple mature mRNAs from a single primary transcript (pre-mRNA), producing protein diversity. Deregulation of AS leads to many human diseases. The physiological role and mechanism of AGGF1 in AS are not clear. Full-length transcriptome sequencing of human pulmonary artery endothelial cells (HPAECs) with AGGF1 silencing revealed 63 121 genes, including 1144 new unannotated genes, and showed that AGGF1 is a general splicing factor regulating AS of 436 genes, including <i>SRSF6</i> regulating AS of many target genes.
