Fig. 5. Two-month Mbnl1−/−/Mbnl2+/− mice exhibit reduced whole-brain volume and enlarged ventricles.
a 3D rendering of representative whole-brain 2D FSE T2w MRIs for 2-mo Mbnl1+/+/Mbnl2+/+, Mbnl1−/−, Mbnl2−/−, and Mbnl1−/−/Mbnl2+/− mice are shown. Colored regions are isocortex and cerebellum (red), hindbrain (pink), white matter areas (yellow), and olfactory gray matter areas (gray). The olfactory bulb was excluded in volume measurements. Scale bar = 2.0 mm. b Whole-brain measurements (mean ± SD) are shown. c Representative axial brain slices from FSE T2w MRI scans where apparent ventricle volumes were defined from hyperintense regions along ventricle locations (yellow filled). Scale bar in 2D axial images denotes 1 mm. d, e Apparent ventricle volume and percent apparent ventricle volume/whole-brain volume (mean ± SD) are shown. Black brackets: Dunnett’s test; Purple brackets: two-tailed t-test. Error bars are standard deviations (SD). In all cases, *p < 0.05, **p < 0.01.
