It is an object of the present invention to identify a gene that exhibits behavior which is characteristic of carcinomas such as thyroid carcinoma, so as to provide a method for detecting carcinoma and a cell growth suppressing agent. The present invention provides a method for detecting carcinoma, which comprises detecting malignant transformation by detecting at least one alteration of gene existing in chromosomal regions 1q41, 3q28, 7q31.2, 8p12, 8q22.2, 8q24.21, 11q4.1, 17q12, 20q11, 9p21.3, 16q13.2, and 16q23.1 in a specimen.

Method for detecting thyroid carcinoma

An object of the present invention is to provide a method for detecting cancer and an agent for suppressing cell growth by identification of genes showing behaviors characteristic in cancer such as esophageal carcinoma. The present invention provides a method for detecting cancer, which comprises detecting canceration through detection of amplification of at least one gene existing in an 1q32-1q41 chromosomal region in a specimen.

Method for detecting esophageal carcinoma and agent for suppressing esophageal carcinoma

An analytical method aided with a nucleic acid microarray, the nucleic acid microarray having a spot (X 1) onto which a first probe nucleic acid is immobilized, the method includes: allowing a labeled sample nucleic acid (A 1) of a sample to be tested to hybridize with the first probe nucleic acid; providing the spot (X 1) with a labeled verification nucleic acid (B) that has a sequence capable of hybridizing with at least a part of the first probe nucleic acid and is labeled with a label different from the labeled sample nucleic acid (A 1), and allowing the labeled verification nucleic acid (B) to hybridize with at least the first probe nucleic acid at all spots; measuring a labeled quantity value (F 1) of the labeled sample nucleic acid (A 1); and measuring a labeled quantity value (Fc 1) of the labeled verification nucleic acid (B).
