Methods We retrospectively enrolled CAD subjects with an abnormal ejection fraction (EF) 50% from our catheterisation data ( N ?=?670). Polymerase chain reactions were performed for amplifying the HMOX1 promoter GT repeating segment to determine the number of repeats. Results In a median follow-...
Pairing between DNAs Containing (GGA:TCC)n Repeats—In this study we show an ability of DNAs containing (GGA:TCC)n repeats to pair with each other, by demonstrating a gel mobility shifted band on gels when DNA fragments containing the repeats are incubated in the presence of HMG1 or ...
· 104M–1, cooperativity coefficient ω = 2.5 ± 0.2, and maximal amount of EtBr molecules intercalated in GT quadruplex (N= 8) were determined. It was proved experimentally by analysis of adsorption isotherms and theoretically by mathematical modeling that the GT quadruplex is capable of ...
