Chowdary (2006)

Description

The authors investigated 52 matched pairs of tissues from colon and breast tumors using Affymetrix U133A arrays and ribonucleic-acid (RNA) amplification. Each tissue pair was gathered from the same patient and consisted of a snap-frozen tissue and a tissue suspended in a RNAlater preservative. Overall, 31 breast-cancer and 21 colon-cancer pairs were gathered, resulting in K = 2 classes with n_1 = 62 and n_2 = 42. A purpose of the study was to determine whether the disease state could be identified using 22,283 gene-expression profiles.
