The present invention provides a specific combination of colon cancer markers based on statistical knowledge, which is capable of detecting a larger number of colon cancer patients in an earlier stage while maintaining high specificity. A multiplex colon cancer marker panel comprising a combination of five colon cancer markers of Carcinoembryonic antigen-related cell adhesion molecule 5, Carbohydrate antigen 19-9, Galectin-4, APEX nuclease and Actin-related protein 2. A method for analyzing colon cancer markers using multiplex colon cancer marker panel.

An insulin resistance marker, a method of evaluating insulin resistance, a method of screening a substance that improves insulin resistance, and a pharmaceutical composition for improving insulin resistance are provided. The insulin resistance marker includes a polypeptide comprising at least any 15 continuous amino acids in the specific amino acid sequence of SEQ ID NO: 1 (sequence of a proepithelin protein). The insulin resistance marker includes a polynucleotide selected from the group consisting of (1) a polynucleotide comprising at least any 45 continuous bases in the base sequence of SEQ ID NO:2 encoding the above specific amino acid sequence, and (2) a polynucleotide that is complementary to the polynucleotide of (1).

Method of screening a substance for improving insulin resistance

The present invention provides a method for global quantitative analysis of protein that is effectively applied also for unpurified samples such as biological samples, and achieves better detection sensitivity and quantitativeness than the conventional NBS method. A method for global quantitative analysis of protein comprising: preparing two states of protein samples, a Protein sample I for analysis and a control Protein sample II; solubilizing the Protein sample I and II by urea or guanidine hydrochloride; subjecting the solubilized Protein sample I and II to modification using 2-nitro[C]benzenesulfenyl chloride and 2-nitro[C]benzenesulfenyl chloride; mixing and desalting the modified Protein sample I and II; resolubilizing by urea or guanidine hydrochloride; reducing and alkylating; subjecting to trypsin digestion in the presence of urea or guanidine hydrochloride; separating the obtained peptide mixture using a media having a phenyl group; and subjecting the enriched modified peptide fragments to mass spectrometry preferably using 3CHCA, 3H4NBA or mixture of 3H4NBA and 4CHCA as a matrix.
