    摘要: Described herein is the finding that polymerase β (Polβ) and N-methylpurine DNA glycosylase (MPG) can be used as biomarkers to evaluate the sensitivity of a subject to combination therapy that includes treatment with either temozolomide (TMZ) and methoxyamine, or TMZ and a poly(ADP-ribose) polymerase (PARP) inhibitor. Thus, provided herein is a method of determining if a subject will be sensitive to TMZ and methoxyamine, or TMZ and a PARP inhibitor by measuring expression of Polβ and MPG in a sample from the subject and comparing expression of Polβ and MPG in the sample to a control. A decrease in expression of Polβ and an increase in expression of MPG relative to the control indicates the subject is sensitive to TMZ and methoxyamine, or sensitive to TMZ and the PARP inhibitor.

    摘要: In various embodiments, the present invention provides fluorescent dyes that are linked to another species through an amino acid or peptide linker. In an exemplary embodiment, the dye is linked to a polyphosphate nucleic acid through an amino acid or peptide linker. These conjugates find use in single molecule DNA sequencing and other applications. In various embodiments, the dye moiety is a cyanine dye. Cyanine dyes that are highly charged, such as those including muliple sulfonate, alkylsulfonate, carboxylate and/or alkylcarboxylate moieties are examples of cyanine dyes of use in the compounds of the invention.
