Caption | Presymptomatic adult Fat1Gt(KST249)Byg/Fat1Gt(KST249)Byg Tg(Myl1-lacZ)1Ibdml/0 (Fat1LacZ/LacZ) mice show selective defects in scapular muscles. (A) Adult mutant mice show visible scapular winging (orange arrow) at stages prior to detectable weight loss (defined as presymptomatic). Pictures (extracted from movies) show a posture in which the mice challenge their shoulder girdle muscles by extending their head as far rostral as possible. At 7 weeks, wasting of the rhomboid muscles can already be detected in presymtomatic mice as they move on a cage grid. Note the large gap (orange arrow) between scapulas (where rhomboids normally maintain scapulas attached to the dorsal spine), not visible in the corresponding position in the wild-type (WT) littermate. (B) At advanced symptomatic stages (30% weight loss, anesthetized mice), there is marked curvature of the spine in the upper back and shoulder area, also visible through X-ray post-mortem imaging. | ||||||
