Figure 1. Col9a1-/- mice have deficient sensorimotor skills (rotarod).

Figure 1

In rotarod tests, Col9a1-/- mice under-performed wildtype (WT) controls. In accelerating trials, Col9a1-/- mice fell from the rotarod sooner than their sex-matched WT controls (male-Col9a1-/- vs. male-WT: p<0.001; female-Col9a1-/- vs. female-WT: p<0.03). Although latencies to fall from the accelerating rotarod for female-Col9a1-/- mice were lower than for female-WTs, differences in constant-speed trials were only significant in males (male-Col9a1-/- vs. male-WT: p<0.01). Data are presented as mean plus standard deviation (n=5 for each sex-genotype); the female-WT constant-speed trial 4 does not have a standard deviation as all female-WTs remained on the rod for the 5 min limit.
