Figure 7 Classification of DEGs by GO annotation. The 3 categories were BP, CC, and MF.
Olfactory and chemosensory-related DEGs and olfactory transduction pathway
As shown in Table 2, 22 identified DEGs were related to olfactory and chemosensory functions. On comparing the MP and NMP groups, 9 DEGs were found to be downregulated, while 13 were upregulated, including 4 IRs or iGluRs, 8 G-protein coupled receptors, 5 transient receptor potential channels (TRP channels), 1 sodium-calcium exchanger, 1 olfactory receptor, 1 isomerase, and 2 chemosensory proteins (CSPs). In addition, the 9 sensory-related pathways and the number of DEGs are shown in Table 3.
