Pathological Changes and Necrosis Are Observed, and Positive Expression of LRG1, α-SMA, and PCNA Is Higher in Rats that Underwent MI Inducement
(A) Staining images of LRG1, α-SMA, and PCNA in rats from the sham and MI groups. (B) Positive expression of LRG1, α-SMA, and PCNA in rats is higher in the MI group than in the sham group. Data followed normal distribution, were expressed as mean ± SD, and were analyzed by an independent sample t test. *p < 0.05 versus the sham group. N = 20.
