Macro creatine kinase type 2 in human colonic tissues.

V Y Rogalsky, I H Koven, D R Miller

    Clinical Biochemistry
    |December 1, 1985
    PubMed
    Summary

    Macro creatine kinase type 2 (MCK-2), a potential colon cancer marker, was purified from tumors, serum, and normal colon tissue. Its presence in tumors and normal colon, but variable serum levels, suggests complex release or removal factors.

    Area of Science:

    • Biochemistry
    • Oncology
    • Gastroenterology

    Background:

    • Macro creatine kinase type 2 (MCK-2) is emerging as a significant tumor marker.
    • Carcinoma of the colon requires sensitive and specific diagnostic markers.

    Purpose of the Study:

    • To purify and characterize Macro creatine kinase type 2 (MCK-2).
    • To investigate the presence of MCK-2 in various sources including normal colonic epithelium and colon cancer cell lines.
    • To understand factors influencing MCK-2 levels in circulation.

    Main Methods:

    • Purification of MCK-2 from tumor tissue, serum, and normal colonic epithelium.
    • Identification of MCK-2 in a colon cancer cell line.
    • Molecular weight determination of purified MCK-2 from different sources.

    Main Results:

    • MCK-2 was successfully purified from tumor tissue, serum, and normal colonic epithelium.
    • MCK-2 was identified in a colon cancer cell line.
    • The molecular weight of MCK-2 was consistent across all tested sources.
    • MCK-2 showed consistent presence in tumors and normal colon tissue, but variable levels in serum.

    Conclusions:

    • MCK-2 is present in both cancerous and normal colonic tissues.
    • Variable serum concentrations of MCK-2 may be influenced by factors affecting its release or clearance.
    • Further research is needed to elucidate the clinical utility of MCK-2 as a colon cancer marker.
