Proteins differentially abundant between good and poor quality halibut eggs. Panel A Representation of differential abundance for 115 proteins detected by TMT labeling based LC-MS/MS based on the significance of differences assessed by Student’s t-tests. Y axis indicates p values while X axis represents test differences. Proteins up-regulated in poor quality eggs (N = 51) are indicated in red while those up-regulated in good quality eggs (therefore down-regulated in poor quality eggs, N = 64) are indicated in blue. The black horizontal line above red and blue markers represent the separation of differentially abundant proteins retained after the p < 0.05 cut off value. A complete list of these proteins along with detailed information on their NCBI gene IDs, NCBI accession numbers, associated protein names from the human database, protein full names, functional categories (according to Fig. 2), significance of differences in abundance (Independent t- test p < 0.05 followed by Benjamini Hochberg correction for multiple tests p < 0.05), relative abundance ratios (GQ/BQ and BQ/GQ, respectively), and regulation tendencies (BQ-upregulated or BQ-downregulated) are given in Table S2.
