Disclosed is a method for supporting a diagnosis of a risk of colorectal cancer recurrence, including the steps of: performing a first measurement to measure the levels of expression of a plurality of genes selected from a first gene group present in a region from 18q21 to 18q23 on the long arm of chromosome 18 in a biological sample collected from a patient with colorectal cancer, a second measurement to measure the levels of expression of a plurality of genes selected from a second gene group present in a region from 20q11 to 20q13 on the long arm of chromosome 20, and a third measurement to measure the levels of expression of a plurality of genes selected from a third gene group including ANGPTL2, AXL, C1R, C1S, CALHM2, CTSK, DCN, EMP3, GREM1, ITGAV, KLHL5, MMP2, RAB34, SELM, SRGAP2P1, and VIM; and determining the risk of colorectal cancer recurrence of the patient based on the levels of expression measured in the measurement step.

The invention provides a method for determining presence of a disease, comprising steps of; measuring the levels of expression of transcription products of genes in a biological sample obtained from a subject suspected of having a target disease, wherein the genes comprise at least one gene belonging to each of at least two disease-determining gene families related to the target disease; obtaining values representing deviations by standardizing the levels of the expression based on the levels of expression of transcription products of the corresponding genes in a plurality of healthy subjects; obtaining the average of values representing deviations with respect to the gene belonging to each of the disease-determining gene families; and determining whether or not the subject has the target disease by using the average; as well as a computer program product for determining presence of a disease.

The present invention relates to novel diagnostic markers for kidney disease and the use thereof.

Diagnostic marker for kidney diseases and use thereof

A treatment solution for preparing a sample solution for nucleic acid amplification reaction is described. The treatment solution comprises dimethyl sulfoxide and aqueous solvent. The sample solution prepared by treating a biological sample with the treatment solution is used in the amplification reaction of a nucleic acid, whereby the nucleic acid can be efficiently recovered from a biological sample, and the influence of an inhibitor during nucleic acid amplification can be effectively reduced.

The present invention provides a novel marker capable of accurately diagnosing the lymph node metastasis of stomach cancer. An mRNA, or a fragment thereof, coding for at least one protein selected from TFF1, AGR2, PRSS8, MUC1, MUC4 and MUC17 can be useful as a lymph node metastasis marker.

Method for judging lymph node metastasis of stomach cancer and kit used therefor

The invention provides a method for judging whether cancer cells are present or not in a sample, comprising a obtaining step of obtaining values related to an expression level of a caner marker gene and a housekeeping gene; a first comparing step of comparing the value related to the expression level of the cancer marker gene with a first threshold value; a normalizing step of normalizing the value related to the expression level of the cancer marker gene based on the value related to the expression level of the housekeeping gene; a second comparing step of comparing the normalized value with a second threshold value; and a judging step of judging whether cancer cells are present or not in the sample based on comparison results obtained in the first and second comparing steps, as well as an apparatus for judging whether cancer cells are present or not.
