METHODS FOR DETERMINING RESPONSIVENESS TO A DIHYDROFOLATE REDUCTASE INHIBITOR

摘要

The present disclosure provides methods for predicting or determining the sensitivity of a cell and/or biological sample obtained from a subject to a DHFR inhibitor including, for example, an antifolate such as Methotrexate or Pemetrexed. Such methods may comprise determining the expression level of one or more miRNAs (e.g., one or more members of the miR-181 and/or miR-143 families) in a cell or biological sample. The methods may be used to determine the responsiveness of a subject to treatment with a DHFR inhibitor.
