Administration of recombinant human GAA as enzyme replacement therapy (ERT) works well in alleviating the cardiac manifestations of PD but loses sustained benefit in ameliorating the skeletal muscle pathology. The limited efficacy of ERT in skeletal muscle is partially attributable to its inability to curb the accumulation of new glycogen produced by the muscle enzyme glycogen synthase 1 (GYS1). Substrate reduction therapies aimed at knocking down GYS1 expression represent a promising avenue to improve Pompe myopathy. However, finding specific inhibitors for GYS1 is challenging given the presence of the highly homologous GYS2 in the liver. Antisense oligonucleotides (ASOs) are chemically modified oligomers that hybridise to their complementary target RNA to induce their degradation with exquisite specificity. In the present study, we show that ASO-mediated <i>Gys1</i> knockdown in the <i>Gaa<sup>−/−</sup></i> mouse model of PD led to a robust reduction in glycogen accumulation in skeletal muscle. In addition, combining <i>Gys1</i> ASO with ERT slightly further reduced glycogen content in muscle, eliminated autophagic buildup and lysosomal dysfunction, and improved motor function in <i>Gaa<sup>−/−</sup></i> mice. Our results provide a strong foundation for validation of the use of <i>Gys1</i> ASO, alone or in combination with ERT, as a therapy for PD.

Subsequently, MALDI–MSI was utilised to investigate the ameliorative effect of PRE against regional metabolic disturbances in AD mouse brains. Principal component analysis (PCA) and partial least squares discrimination analysis (PLS-DA) showed that the metabolic profiles in Ccx, Hp, corpus callosum (Cc), thalamus (Th) and hypothalamus (Hth) of PRE-treated mice were remarkably distinguished from AD, indicating that notable spatial metabolic disturbances could be changed by PRE (Figures 1A and S4).

Details of the study design and statistical analysis are described in Supporting Information. All patients were aged between 19 and 78 years. Among them, there were 15 (48.4%) males and 16 (51.6%) females. In the total population, 22 (71.0%) participants had distant metastases at first diagnosis, while another nine (29.0%) were categorised as unresectable STS without metastases. Among the 22 metastatic STSs, 15 (68.2%) had metastatic lesions in two or more organs. The most common primary lesions were trunk and extremity (36.7%), followed by lung (20.0%), brain (16.7%), head (13.3%), spleen (10.0%) and breast (3.3%). During metastasis, most cases spread to lungs (63.6%), followed by other sites including bones (50.0%), lymph nodes (36.4%), liver (27.3%), pleura (13.6%) and muscle (9.1%). Of them, 18 (58.1%) underwent prior surgery, 12 (38.7%) received prior first-line therapy and four (12.9%) received prior radiotherapy (Table S1).</p><p>As of the data cutoff on 26 November 2024, patients received between 1 and 35 treatment cycles, with a median of eight cycles.
