應用

Pyridostatin hydrochloride has been used as a G-quadruplex (G4)-stabilizing ligand to check the effect of G4s on fork progression. It has also been used as a G4-stabilizing ligand to study the effect of G4 on apurinic/apyrimidinic endonuclease 1 (APE1) mediated Kirsten rat sarcoma virus (KRAS) expression in pancreatic ductal adenocarcinoma (PDAC) cell lines.

生化/生理作用

Pyridostatin is a highly selective G-quadruplex (G4) interacting molecule. It retards the growth of human cancer cells by inducing replication/transcription dependent on DNA damage. Pyridostatin stabilizes G-quadruplexes, targeting the proto-oncogene SRC and telomeric G4, inducing DNA damage and cell-cycle arrest.

Growing evidence indicates that RNA G-quadruplexes have important roles in various processes such as transcription, translation, regulation of telomere length, and formation of telomeric heterochromatin. Investigation of RNA G-quadruplex structures associated with biological events is therefore essential to understanding the

G quadruplexes (G4s) and R loops are noncanonical DNA structures that can regulate basic nuclear processes and trigger DNA damage, genome instability, and cell killing. By different technical approaches, we here establish that specific G4 ligands stabilize G4s and simultaneously

Class switch recombination (CSR) at the immunoglobulin heavy-chain (IgH) locus is associated with the formation of R-loop structures over switch (S) regions. While these often occur co-transcriptionally between nascent RNA and template DNA, we now show that they also form
