This work reports on magnetoelectric biomaterials suitable for effective proliferation and differentiation of myoblast in a biomimetic microenvironment providing the electromechanical stimuli associated with this tissue in the human body. Magnetoelectric films are obtained by solvent casting through the combination of a piezoelectric polymer, poly(vinylidene fluoride-trifluoro-ethylene), and magnetostrictive particles (CoFeO). The nonpoled and poled (with negative and positive surface charge) magnetoelectric composites are used to investigate their influence on C2C12 myoblast adhesion, proliferation, and differentiation. It is demonstrated that the proliferation and differentiation of the cells are enhanced by the application of mechanical and/or electrical stimulation, with higher values of maturation index under mechanoelectrical stimuli. These results show that magnetoelectric cell stimulation is a full potential approach for skeletal muscle tissue engineering applications.

Background: Alzheimer's disease (AD) patients and animal models exhibit an altered gut microbiome that is associated with pathological changes in the brain. Intestinal miRNA enters bacteria and regulates bacterial metabolism and proliferation. This study aimed to investigate whether the manipulation of miRNA could alter the gut microbiome and AD pathologies.

X-linked hypophosphatemia (XLH) is a rare and progressive disease, due to inactivating mutations in the phosphate-regulating endopeptidase homolog X-linked (PHEX) gene. These pathogenic variants result in elevated circulating levels of fibroblast growth factor 23 (FGF23), responsible for the main clinical manifestations of XLH, such as hypophosphatemia, skeletal deformities, and mineralization defects. However, XLH also involves muscular disorders (muscle weakness, pain, reduced muscle density, peak strength, and power).

Integrins constitute a large and diverse family of cell adhesion molecules that play essential roles in regulating tumor cell differentiation, migration, proliferation, and neovascularization. Tumor cell-derived exosomes, a subtype of extracellular vesicles, are enriched with integrins that reflect their cells of origin. These exosomal integrins can promote extracellular matrix remodeling, immune suppression, and vascular remodeling and are closely linked to tumor progression and metastasis, acting as pivotal players in mediating organ-specific metastasis.

E3 ubiquitin ligases regulate the cellular proteome proteasome-dependent protein degradation; however, there exist limited studies outlining their non-canonical functions. RNA-binding ubiquitin ligases (RBULs) represent a subset of E3 ligases that harbour RNA-binding domains, making them uniquely positioned to function as both RNA-binding proteins and E3 ligases. Our initial microarray screen for E3 ligases from mouse cortical neural progenitor cells identified MEX3B, a known RNA-binding ubiquitin ligase, to be differentially expressed.

Skin scar formation is a critical pathological process in wound healing, but its underlying regulatory mechanisms remain incompletely elucidated. By integrating analyses of Bulk-RNA seq and single-cell RNA sequencing (scRNA-seq) data, we identified that ferroptosis-related biological processes potentially play a key role in skin scar formation. Further mechanistic studies demonstrated that in human dermal fibroblast cells, the ferroptosis regulator TIMP metallopeptidase inhibitor 1 (TIMP1) significantly promotes fibroblast differentiation toward a mature phenotype through interactions with cystatin C (CST3), characterized by upregulated expression of myofibroblast differentiation markers such as α-smooth muscle actin (α-SMA) and connective tissue growth factor (CTGF), along with enhanced cell proliferation and migration abilities.
