Genetic mouse models of Dnm1l knockout in non-cardiac tissues

Genetic model Outcome Refs
Basal characterization Effects of pathological stress
Skeletal muscle-specific knockout Reduced body growth, muscle fibre number and size. Defects in respiratory complex assembly and function. Lethality by postnatal day 30. NR 80
Tamoxifen-inducible, skeletal muscle-specific knockout Reduced body weight at 50 days post-tamoxifen. Reduced muscle mass and fibre size 70–180 days post-tamoxifen. Mitochondrial dysfunction and impaired mitophagy. NR 80
T cell-specific knockout Impaired migration and expansion of developing thymocytes. Accelerated tumour growth. 121
Myeloid/macrophage-specific knockout Impaired macrophage-mediated uptake of apoptotic cells (i.e. efferocytosis). Accelerated plaque necrosis in the Ldlr−/− model of atherosclerosis. Protection against vascular remodelling and fibrosis following arterial injury. Reduced macrophage activation and cell proliferation in injured arteries. 126,153
Liver-specific knockout Reduced liver and white adipose tissue weights. Reduced serum triacylglycerol and total cholesterol levels. Protection from high-fat diet-induced obesity. 12,152
Endothelial cell-specific knockout NR Protection against TNF-driven endothelial leukocyte adhesion. 155

DNM1L, dynamin-1-like protein (also known as dynamin-related protein 1 (DRP1)); LDLR, low-density lipoprotein receptor; NR, not reported; TNF, tumour necrosis factor.
