Abstract

Certain molecular characteristics of cancer cells or tumors can be indicative of their sensitivity to various combination therapies. The cancer cells or tumors exhibiting such molecular profiles, such as upregulation of genes associated with mitosis or meiosis, can be sensitive to additive and more than additive effects of combination therapies. Methods for identifying, selecting, and/or treating cancer patients whose cancer is amenable to combination therapies including an antiandrogen or androgen antagonist in combination with a Plk inhibitor are disclosed. Administration of the combination of the active agents can reduce cancer cell proliferation or viability and/or tumor burden in a subject with cancer to the same degree, or a greater degree than administering to the subject the same amount of either active agent alone.

Abstract

This invention provides compositions and methods for rapid isolation and purification of nucleopolymers from biological samples using anionic exchange media. The method of this invention can utilize commercially available anion exchanger materials with selected solutions of known ionic strength for absorption and elution. The medium/nucleoprotein bound complex may be optionally stored or transported, and is subsequently treated with eluents to remove undesirable proteins and inorganic salts. The partially purified complex may also be stored or transported. This method is particularly advantageous since it allows rapid isolation and purification of soluble nucleic acids from a large volume of biological fluids with easy handling and storage, stabilizing the samples against degradation prior to analysis. It also permits the purification and identification of shorter fragments of nucleic acids from bodily fluids which, until now, had not been identified. The method is widely useful to prepare samples formats that are convenient in diagnostic analytical methods.
