the experiment uses biotin-labelled BLM-G4 to incubate with HT-29 cell lysates, and uses streptavidin agarose beads to pulldown BLM-G4-binding proteins. Utilize LC-MS/MS to annotate and quantify the proteins pulled down by BLM-G4.
The human Werner and Bloom syndromes (WS and BS) are caused by deficiencies in the WRN and BLM RecQ helicases, respectively. WRN, BLM and their S. cerevisiae homologue Sgs1, are particularly active in vitro in unwinding G-quadruplex DNA (G4-DNA), a family of non-canonical nucleic acid structures fo...
Bloom syndrome protein (BLM), a RecQ family DNA helicase, is consistently overexpressed in multiple malignancies, yet its therapeutic potential remains largely unexplored. Herein, we focused on targeting the BLM promoter G-quadruplex (BLM-G4) to inhibit the BLM signaling pathway. We first characteri...

Bloom syndrome is a rare autosomal recessive genetic instability and cancer predisposition syndrome caused by loss of function mutations in the BLM RECQ helicase gene. To ask if some of the distinctive pathological features of Bloom syndrome might reflect altered gene expression, we analyzed global ...
Homologous recombination (HR) is a key process for repairing DNA double strand breaks and for promoting genetic diversity, and it occurs unevenly throughout the genome. G-quadruplexes (G4s) are stable secondary structures widely present across the genome, which function in regulating gene transcript...
