3.2 Correlation analysis between DEGs and DEPs
Totally, 74611 DEGs and 391 DEPs were correlated and analyzed according
to their difference multiples (Figure 1A). GO analysis was used to
classify the Biological process, Molecular function and Cellular
components after the transcriptomic and proteomic correlate analysis
(Supplementary Figure 1A). The results showed that these genes were
mainly closely related to metabolism and redox (Supplementary Figure 1B
and C). From KEGG annotation, the data as well as mainly closely related
to metabolism and redox (Supplementary Figure 2). After correlation
analysis, we found that 249 of the transcriptome and proteome data are
overlapped, and 142 proteins are differential proteins after correlation
analysis (Figure 1C). Next, we selected all the proteins (30 proteins)
related to digestion and metabolism from 142 different proteins for
further study (Supplementary Table 3). Then based on whether using PCR
can obtain the open reading frame (ORF) of the genes form the
transcriptome data, a total of 9 proteins were selected (Table 3).
