Patent ID: 10697020

Abstract:
The current disclosure describes methods for identifying subjects that would benefit from treatment with a chemotherapeutic agent. The disclosure is based in part on the observation that miR-129 expression levels are reduced in colorectal cancer. Accordingly, the current disclosure provides therapeutic compositions and methods for altering the expression of a miR-129 effector. Described herein are methods for characterizing the stage of colorectal cancer in a subject, based on the levels of miR-129 expression. The disclosure also identifies miR-129 as a predictive biomarker for cancer diagnosis and the subsequent treatment with directed therapeutic agents including but not limited to miR-129 nucleic acid molecules and/or a chemotherapeutic agent. The current disclosure also identifies novel therapeutic agents that modulate the level of BCL2, TS and/or E2F3 expression, as well as sensitize a subject to treatment with a chemotherapeutic agent.
