nws quadruplex tsim G-nplua nuj sequences yog unevenly faib thoob plaws hauv tib neeg genome.Lawv qhov kev txhawb nqa ntawm cov neeg txhawb nqa oncogenic thiab telomeres tau tsim kev txaus siab rau kev tsom mus rau G-quadruplex (GQ) rau kev kho mob qog noj ntshav.Ntawm no, peb nthuav qhia ntau qhov kev tshuaj xyuas ntawm qhov kev sib haum xeeb thiab kev hloov pauv ntawm GQ tsim cov kab ke ntsuas los ntawm ib qho fluorescence molecule.Tsis tas li ntawd, peb hais txog cov khoom no rau GQ lub hom phiaj ligands thiab G4 resolvase 1 (G4R1) protein khi.Peb qhov tshwm sim qhia tau hais tias ob lub voj voog (tsis yog-G Cheebtsam) ntev thiab ntu ua rau muaj kev sib haum xeeb ntawm GQ.Lub sij hawm tiag tiag ib qho molecule ib txoj kab qhia tau hais tias lub folding dynamics kuj nyob ntawm lub voj muaj pes tsawg leeg.Peb pom tau hais tias GQ-stabilizing me me molecules, N-methyl mesoporphyrin IX (NMM), nws cov analog, NMP thiab G4R1 protein khi xaiv rau qhov sib npaug ntawm GQ conformation.Peb qhov kev tshawb pom taw qhia txog qhov nyuaj ntawm GQ folding tswj hwm los ntawm lub voj ntev thiab qhov sib lawv liag thiab seb GQ conformation txiav txim siab qhov me me molecule thiab protein binding propensity.
