TLR9 and cancer: In particular, GO terms related to biological processes involved in tumorigenesis, such as “positive regulation of receptor signaling pathway via JAK-STAT,” “signal transduction,” “positive regulation of miRNA transcription,” “NK T cell differentiation,” “protein phosphorylation,” and “positive regulation of toll-like receptor 9 signaling pathway” (Table 4, shown in underlined), and KEGG pathways involved in tumorigenesis, such as “PI3K-Akt signaling pathway” and “Proteoglycans in cancer” (Table 5, shown in underlined) were detected.
