To explore the relationship between α-actinins-3(ACTN3)genotype and aerobic endurance in north-ern Han nationality Chinese,the authors compared ACTN3 R577X genotype of 123 northern Han elite long-distance running athletes with that of 206 normal northern university students through polymerase chain reaction and restric-tion fragment-length polymorphism(PCR-RFLP).

The changes of α-actinin in renal tubular epithelial cells during kidney ischemia/reperfusion injury in neonatal rats.;

α-actinin is an abundant actin-bundling protein that can be found both in muscle and in nonmuscle cells .

Objective To observe the distribution,intensity and changes of the percentage of area during aging of α-actinin and myomesin in ventricular myocyte of the developing and mature rats,and to probe the biological significance.

The Preparation and Identification of Rabbit Anti-human Skeletal Muscle α-actinin Antiserum;

Objective To determine the position ultramicro-distribution and the quantity expression changes of α-actinin in the neurons differentiated from temporal lobe cerebral cortex nerve stem cells in newborn mouse at various time intervals with energy dispersive analysis system of X-ray.

Aim To observe the expression of α-actinin-4 in the kidney in diabetic rats and the effect of losartan on it.

AIM:To investigate the effect of Jiazhu onα-SMA and TGF-β1 expression in the liver of rats with hepatic fibrosis and its anti-fibrosis mechanism.

ALT and AST of serum,the histopathology of the mice liver and the mRNA expression of TGF-β1,α-SMA and collagen-Ⅰwere detected.
