Article Abstract

Duchenne muscular dystrophy (DMD) is an X-linked genetic disorder characterized by progressive degeneration of skeletal and cardiac muscles, typically beginning in early childhood. Here, we describe the generation of two isogenic induced pluripotent stem cell (iPSC) lines engineered using CRISPR-Cas12 to introduce specific nonsense mutations in the DMD gene: c.4729C>T (p.Arg1577Ter) and c.5713G>T (p.Arg1905Ter). The edited iPSC lines retain normal karyotypes, express key pluripotency markers, and exhibit the capacity to differentiate into derivatives of all three germ layers. These models provide powerful tools for investigating DMD pathogenesis, uncovering mechanisms of genetic compensation, and evaluating potential therapeutic strategies.

Adeno-associated virus (AAV) vectors are widely used in gene therapy, particularly for liver-targeted treatments. However, predicting human-specific outcomes, such as transduction efficiency and hepatotoxicity, remains challenging. Reliable models are urgently needed to bridge the gap between preclinical studies and clinical applications.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a hereditary infiltrative cardiomyopathy characterized by fibrofatty replacement of the right ventricular myocardium, which may extend to the left ventricle in the advanced stages. Clinically, the condition is commonly associated with right ventricular dilation, malignant arrhythmias, and an increased risk of sudden cardiac death. In this study, we successfully established induced pluripotent stem cell (iPSC) lines from peripheral blood mononuclear cells of ARVC patients carrying a heterozygous LMNA gene mutation (c.

Cardiomyopathies, a leading cause of mortality, are associated with dysfunctional intercalated discs, which connect neighbouring cardiomyocytes and ensure proper contractility. In human cardiac diseases, loss-of-function mutations of the intercalated disc-associated protein Nebulin-Related Anchoring Protein (NRAP) have been reported. NRAP plays a crucial role in myofibril assembly and mechanotransduction, however, its regulatory functions remain unclear.

Human cord blood (CB) myeloid progenitor reprogramming to a high-fidelity human induced pluripotent stem cell (hiPSC) state can be achieved using non-integrating episomal vectors and stromal signals. These conventional, primed CB-hiPSC lines can subsequently be chemically reverted with high efficiencies to a blastomere-like Tankyrase/PARP Inhibitor-Regulated Naive Stem Cell (TIRN-SC) state with functional totipotency. PARP-regulated TIRN-SCs are human stem cells with high epigenetic plasticity, stable epigenomic imprints, and have greater differentiation potency than conventional, lineage-primed hiPSCs.

Cancer cachexia is a highly debilitating clinical syndrome of involuntary body mass loss featuring profound muscle wasting leading to high mortality. Notably, cardiac wasting is prominent in cancer patients and cancer survivors. Cachexia studies present significant challenges due to the absence of human models and mainly short-term animal studies.
