  • Publication number: 20140287943
    Abstract: The present disclosure is directed to detecting colon disorders by measuring the expression of SHIP1 in a sample of PBMCs. One method includes the following steps, obtaining a sample including peripheral blood mononuclear cells (PBMCs) from a subject and determining whether SHIP1 is underexpressed in the PBMCs or lacks normal enzymatic activity. The present disclosure is also directed to a method of determining the expression of SHIP1 protein expression and SHIP1 enzyme activity in PBMCs. This method includes the following steps, obtaining a sample comprising PBMCs from a subject and determining the amount of SHIP1 in the PBMCs.
