Fig. 1From: Differential proteomics of placentas reveals metabolic disturbance and oxidative damage participate yak spontaneous miscarriage during late pregnancyExpression status, principal component analysis (PCA) and heatmap of the total identified proteins in the yak placentas. (a) Pie chart shows the rate of identified peptide coverage; (b) Boxplot indicates the total protein expression in the different placenta samples; (c) PCA biplot exhibits the aggregation of the intragroup samples based on the first two principal components; (d) Heatmap demonstrates the global expression difference of the total proteins between the normal and aborted placenta samples Back to article page
