Abstract: This invention relates to a composition and a method for prediction of a response to Trastuzumab therapy in a breast cancer patient, and more specifically, a composition, a kit, a DNA chip, and a method for predicting a response to Trastuzumab therapy by using polynucleotides each comprising a nucleotide sequence represented by any of SEQ ID NOs: 1 to 9, 11 to 19, and 21 to 23 in the Sequence Listing or a nucleotide sequence derived therefrom by substitution of u with t, mutants thereof, derivatives thereof, or fragments thereof comprising at least 16 continuous nucleotides, or a polynucleotide comprising a complementary sequence thereof, and using an increase or decrease in Her2 protein expression level as an indicator.

Abstract: This invention relates to a composition, kit, or DNA chip for use in diagnosis of esophageal cancer, which comprises a plurality of polynucleotides selected from the group consisting of polynucleotides whose expression levels are varied in esophageal cancer tissues obtained from esophageal cancer patients when compared with cancer-free esophageal tissues obtained from esophageal cancer patients, mutants thereof, and fragments thereof, and to a method for detecting esophageal cancer using the composition, kit, or DNA chip.
