WebThe DNA damage response factor 53BP1 functions at the intersection of two major double strand break (DSB) repair pathways--promoting nonhomologous end-joining (NHEJ) and inhibiting homology-directed repair (HDR)--and integrates cellular inputs to ensure their timely execution in the proper cellular contexts. WebRemarkably, the 'traffic-light reporter' system revealed that CDYL1 mainly promotes homology-directed repair (HDR) of DSBs in vivo. Consequently, CDYL1-knockout cells display synthetic lethality with the chemotherapeutic agent, cisplatin. Altogether, our findings identify CDYL1 as a new component of the DDR and suggest that the HDR-defective ... WebAug 25, 2024 · The addition of Cas9 target sequences to long single-stranded DNAs, combined with cocktails of small molecules to boost homology-directed repair, leads to marked enhancement of non-viral knock-in ... body art bloodborne pathogens
