b, Quantification of RAD51 foci in KB1P-G3 cells (with or without REV7 depletion) transfected with an empty vector (GFP) or vectors containing mouse or human

We observed this phenomenon by immunofluorescence of endogenous HELB in MEFs, where HELB loses its nuclear enrichment in cells that are undergoing DNA replication (Figure 6A and

In addition, we found that XRN2 loss also causes PARP inhibitor (PARPi) resistance of Brca1; p53-deficient mouse mammary tumor cells both in vitro and in vivo.. We aim

In particular, the groups of Jos Jonkers and Andre Nussenzweig found that loss of 53BP1 enhanced end resection at DSBs and restored BRCA1- independent HR,

In Chapter 2, we report that loss of REV7 (also known as MAD2L2) in mouse and human cells rescues CTIP-dependent end resection of DSBs in BRCA1- deficient

Consistent met de nieuwe rol van HELB als antagonist van resectie, leidt verlies van HELB ook tot gedeeltelijk herstel van HR en resistentie tegen PARP remming
