Therapeutic efficacy, biomarker signatures, and translatability of semaglutide in the liver biopsy-confirmed GAN DIO-MASH mouse model
Background & aim: Glucagon-like peptide-1 (GLP-1) receptor agonists have emerged as promising therapeutic candidates for metabolic dysfunction-associated steatohepatitis (MASH). Importantly, semaglutide was recently approved as the first GLP-1-based treatment for people with MASH with moderate-to-severe fibrosis. Translational models that recapitulate…
Quantitative 3D high-resolution imaging of skeletal muscle morphology in aged lean and diet-induced obese mice
Background & aim: Effective treatment of muscle diseases requires comprehensive, multidimensional assessment of muscle structure, mass, and function. This need is particularly evident in sarcopenia, where age-related loss of muscle mass and quality drives functional decline, increased morbidity, and frailty…
Superior Efficacy and Clinical Translatability of CagriSema Compared to Cagrilintide and Semaglutide in the DIO rats
Background & aim: Long-acting amylin analogues offer mechanistic complementarity to incretin-based therapies for obesity. Accordingly, CagriSema, a fixed-dose combination of the amylin analogue Cagrilintide and the GLP-1 analogue Semaglutide, has demonstrated superior weight loss compared with either agent alone in recent clinical trials…
Characterization of the Cisplatin-Induced Mouse Model of Cachexia
Background & aim: Cachexia is a complex metabolic syndrome observed in conditions such as cancer, chronic heart failure, and chronic obstructive pulmonary disease, and is characterized by weight loss, reduced food intake (anorexia), loss of lean body mass (sarcopenia), and…
High-Throughput 3D Imaging for Quantifying Dexamethasone-Induced Skeletal Muscle Atrophy in Mice
Background & aim: Accurate assessment of muscle mass remains a major challenge in preclinical models of sarcopenia, obesity, and drug-induced atrophy. Traditional readouts such as lean mass from body composition scans lack spatial resolution and anatomical specificity, especially in conditions…
High-Throughput 3D Imaging for Quantifying b2-Adrenergic Receptor Agonist-Induced Skeletal Muscle Hypertrophy in Mice
Background & aim: Accurate assessment of muscle mass remains a major challenge in preclinical models of sarcopenia, obesity, and drug-induced atrophy. Traditional readouts such as lean mass from body composition scans lack spatial resolution and anatomical specificity, especially in conditions…
