Webconstitutively active TLR4 (caTLR4) in mice carrying pLAP-tTA or pAlb-tTA, under a tetracycline withdrawal-inducible system. Liver progenitor cell induction accel-erated liver tumor development in caTLR4-expressing mice. Lentiviral shRNA li-brary screening identified histone H3K4 methylase SETD7 as central to activation of TLR4.
Web6 jul. 2024 · A group of putative Type III RM systems that use m4C modification for host DNA protection were identified using Pacific Biosciences single-molecule real-time (SMRT) sequencing of bacterial genomic DNAs to identify asymmetric motifs having m4C methylation in one DNA strand [ 17 ]. Web18 dec. 2024 · Interestingly, Zebularine exerts its demethylation activity by stabilizing the binding of DNMT to DNA, hindering methylation and reducing dissociation. Thus, it can capture the enzyme and prevent conversion at other sites. Zebularine can enhance the chemosensitivity and radiosensitivity of tumor cells.
