In this study, we established ecDNA-containing cell models by either transfecting synthetic circular DNA or excising endogenous chromosomal DNA. We found that ecDNA can be stable maintained in these cell models. By identifying proteins on nascent DNA, we found DNA damage repair pathway was significa...
This study was conducted by using Flag tag to IP proteins expressed with fusion small peptides encoding LncRNA MAGI2-AS3 and identified by high resolution mass spectrometry.
PARP1 mediates poly-ADP-ribosylation of proteins on chromatin in response to different types of DNA lesions. PARP inhibitors are used for the treatment of BRCA1/2-deficient breast, ovarian, and prostate cancer. Loss of DNA replication fork protection is proposed as one mechanism that contributes to ...
Triple negative breast cancer (TNBC) is histologically characterized by the absence of the hormone receptors estrogen and progesterone, in addition to having a negative immunostain for HER-2. The aggressiveness of this disease and lack of targeted therapeutic options for treatment is of high clinic...
