Oncofetal protein IMP3, a new cancer biomarker.

Published: May 2014

IMP3 is a member of a family of RNA-binding proteins that consists of IMP1, IMP2 and IMP3. These proteins contain 2 RNA recognition motifs and 4 K-homology domains that allow them to bind RNAs strongly and specifically. IMP3 is an oncofetal protein involved in embryogenesis and its expression is associated with a number of malignant neoplasms. IMP3 is associated with aggressive and advanced cancers and is specifically expressed in malignant tumors but is not found in adjacent benign tissues. Moreover, in vitro studies have shown that IMP3 promotes tumor cell proliferation, adhesion, and invasion. This review focuses on the studies of IMP3 expression in different cancers and emphasizes the potential utility of IMP3 in routine surgical pathology practice. We also discuss IMP3 as a prognostic biomarker for cancer patients' outcomes.

Introduction: The role of IMP3, CDK4, MDM2 and β-catenin proteins in Enchondroma and Central Chondrosarcoma is not totally understood. The aim of this study is to evaluate the immunoexpression of these proteins, associating histological grade, clinical data and prognosis to these tumors.

Methods: This is a retrospective-analytical study of 32 Enchondroma and 70 Central Chondrosarcoma.

Cervical cancer remains one of the leading causes of death from malignant diseases in women worldwide. Primary and secondary prevention have led to better outcomes in developed countries, whereas in developing countries, cervical cancer continues to be responsible for an unjustifiably high number of fatalities. The discovery of new tumor biomarkers can lead to earlier diagnosis, better therapeutic decisions, and improved treatment methods.

Article Synopsis
  • - The study investigates the use of IMP3 immunohistochemistry (IHC) as a diagnostic tool for primary diffuse large B-cell lymphoma of the central nervous system (CNS-DLBCL), which is challenging to diagnose due to limited biopsy material.
  • - Results showed strong IMP3 expression in 100% of CNS-DLBCL samples, while it was also present in 88.2% of other DLBCLs, but not in inflammatory brain diseases.
  • - While IMP3 IHC can help distinguish CNS-DLBCL in cases with limited tumor cells, most cases can be diagnosed without it, indicating that it serves as a supportive diagnostic technique rather than a primary one.

Article Synopsis
  • - The study aimed to differentiate between reactive atypia and dysplasia in cholecystectomy specimens using immunostains for IMP3, p53, and S100P in a sample of 54 cases.
  • - Results indicated that normal and reactive atypia cases mostly showed negative IMP3 and wild-type p53, while dysplasia cases had significant positivity in IMP3 and aberrant p53 patterns.
  • - The findings suggest that positive IMP3 or abnormal p53 expression could help pathologists distinguish dysplasia from reactive atypia in challenging cases.
