 GDF11,10.1007/s10522-018-09789-9,fish Nothobranchius guentheri,n/a,all,55.0%,<0.001,serum,n/a,n/a,6,9,n/a,n/a,months,decreased gene expression,3,3,ANOVA,protein,ELISA,"It was found that GDF11 concentration in the sera of 9-month-old fish was considerably lower than that of 6-month-old fish (p<0.001). Similarly, GDF11 concentration in the different tissues including the intestine was significantly reduced in 9-month-old fish, compared with that of 6-month-old fish. For both 6- and 9-month-old fish, GDF11 level was highest in the brain. Broadly speaking, the change pattern of GDF11 levels was basically consistent with that of gdf11 mRNA levels. The only difference was that in the intestine, GDF11 content decreased with age but gdf11 mRNA did not.",n/a
