Stem cell, una alternativa al trasplante cardíaco en el tratamiento de la insuficiencia cardíaca Stem cell, an alternative to heart transplant in the treatment of heart failure

open access: yesRevista Cubana de Medicina, 2005
El concepto tradicional mantenido por años sobre la incapacidad del corazón adulto para renovar sus células ha tenido que ser revisado ante la evidencia de los resultados obtenidos por numerosos estudios que demuestran la existencia en el corazón humano ...

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

open access: yesResponsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Vitamin a potentiates sheep myoblasts myogenic differentiation through BHLHE40-modulated ID3 expression

open access: yesBMC Genomics
Background Vitamin A and retinoic acid (RA, a metabolite of vitamin A), are inextricably involved to the development of skeletal muscle in animals. However, the mechanisms regulating skeletal muscle development by vitamin A remain poorly reported.

Epigenetics of Genes Preferentially Expressed in Dissimilar Cell Populations: Myoblasts and Cerebellum

open access: yesEpigenomes
While studying myoblast methylomes and transcriptomes, we found that CDH15 had a remarkable preference for expression in both myoblasts and cerebellum. To understand how widespread such a relationship was and its epigenetic and biological correlates, we ...

The Molecular Diagnosis of Myopathies: Integrating Genomic, Proteomic, and Pathological Insights Toward Precision Medicine

open access: yesClinical Genetics, EarlyView.
Advances in genomic, proteomic, and transcriptomic technologies are transforming the diagnosis of genetic myopathies. When integrated with traditional muscle pathology, multi‐omics approaches improve diagnostic yield, clarify disease mechanisms, and support more precise, mechanism‐based therapeutic strategies for patients with neuromuscular disorders ...

Dissection of Mitochondrial Function via Chemical Perturbation and Single‐Cell Profiling

open access: yesCell Proliferation, EarlyView.
We establish a systematic framework to dissect mitochondrial function at the module level by combining targeted chemical perturbations with scRNA‐seq. This approach reveals shared and module‐specific programs linking mitochondrial activity to mito‐nuclear communication, stress response, and cell cycle, highlighting the tight coupling between ...

Resistance‐exercise‐induced stress intervenes in TGF‐β signaling by cooperatively downregulating nuclear αB‐crystallin and SMAD4 in human skeletal muscle fibers

open access: yesThe FEBS Journal, EarlyView.
Alpha‐crystallin B chain (CRYAB) has been reported to stabilize mothers against decapentaplegic homolog 4 (SMAD4) in transforming growth factor‐β (TGF‐β) signaling, enabling target gene transcription. We show nuclear CRYAB–SMAD4 interaction for the first time in human skeletal muscle fibers and its regulation by exercise.

GCN2 in proteostasis: structural logic, signalling networks and disease

open access: yesThe FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Exercise‐related microRNAs in Caenorhabditis elegans regulate calcium homeostasis and mitochondrial dynamics: Conserved pathways, divergent microRNAs

open access: yesThe FEBS Journal, EarlyView.
Exercise‐related microRNAs cel‐miR‐249‐3p and cel‐miR‐77‐5p in C. elegans regulate lifespan, fitness, mitochondrial morphology and membrane potential. Although lacking direct mammalian orthologs, H2O2‐induced microRNAs mmu‐miR‐181a‐5p and mmu‐miR‐378a‐3p regulate myogenesis, autophagy, mitochondrial content and respiration in murine myoblasts ...

Effects of Broiler Breeder Age on Egg Quality, Incubation Performance, and Early Progeny Physiological and Muscle Fiber Development

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the effects of breeder hen age on the incubation performance, embryonic development, and progeny quality of Cobb500 broiler breeders at 39, 51, and 69 weeks of age. A total of 870 eggs were collected, of which 810 were incubated; these were assigned to a completely randomized design with three treatments and nine ...
