    Chloroquine dna mobility

    To this aim we compared electrophoretic behavior of three different families of DNA topoisomers: (i) supercoiled DNA molecules, where supercoiling covered the range extending from covalently closed relaxed up to naturally supercoiled DNA molecules; (ii) postreplicative catenanes with catenation number increasing from 1 to ∼15, where both catenated rings were nicked; (iii) knotted but nicked DNA molecules with a naturally arising spectrum of knots. For better comparison, we studied topoisomer families where each member had the same total molecular mass.

    Gel mobilities of linking-number topoisomers and their dependence on DNA helical repeat and elasticity. as specified. In many experiments both the gel and buffer were supplemented with low concentrations of chloroquine. Effects of field and gel concentration on the exponential dependence of reciprocal mobility on DNA length. In order to assess the importance of DNA binding, we have measured the affinity of DNA for chloroquine by equilibrium dialysis using tritiated chloroquine. The dissociation constant of the DNA-chloroquine complex varied from 27 microM to 2.6 mM, depending on the ionic strength of the buffer. A, the process of autophagy. B, inhibition of autophagy by chloroquine could sensitize not only cancer cells, but also kidney cells to chemotherapy, resulting in DNA damage, production of mitochondrial reactive oxygen species, and cell death.

    We observed that catenated, knotted and supercoiled families of topoisomers showed different reactions to changes of agarose concentration and voltage during electrophoresis. For knotted and supercoiled molecules, we analyzed dimeric plasmids whereas catenanes were composed of monomeric forms of the same plasmid.

However, in binding studies, different investiga- tors have found very different Kos Table I, con- founding attempts to assess the pharmacological relevance of chloroquine-DNA interactions.

    Effects of culture conditions on DNA supercoiling in E. coli and S. enterica wild type A–D and Δfis mutants E–H. All densitometry plots illustrate the electrophoretic mobility of pUC18 topoisomers in agarose gels containing chloroquine 2.5 µg ml −1; in these conditions topoisomers with higher superhelical density migrate farther x‐axis. The mode of binding of EtBr is intercalation between base pairs. This binding changes the charge, weight, conformation, and flexibility of the DNA molecule. Since DNA molecules are sized by their relative movement through a gel compared to a molecular weight standard, mobility measurements can be critical to size determinations.
