Trichomonas vaginalis-derived secretory products (TvSP) induces protein O-GlcNAcylation and O-GlcNAc transferase (OGT) expression in mast cells, which is prevented by LTB4 receptor (BLT1) siRNA. TvSP-induced migration, ROS generation, and IL-8 release are suppressed by OGT inhibitor or OGT siRNA. These results suggest that BLT1-mediated OGlcNAcylation is important for mast cell activation during trichomoniasis.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
