Abstract

Purpose

Autotaxin (ATX) is molecularly identical to lysophospholipase D (lysoPLD) and is a main enzyme producing lysophosphatidic acid (LPA), which mediates a broad range of cellular responses including stimulation of cell motility.

Patients and Methods

Using immunohistochemical staining, we examined the expression of ATX/lysoPLD in 98 cases of early colorectal cancer with submucosal invasion. ATX/lysoPLD was highly expressed in infiltrating cells in tumor tissue in the submucosal layer, which were characterized as mast cells.

Results

The number of ATX/lysoPLD-positive cells was significantly greater in tumors with a macroscopically depressed lesion than in tumors without depression. The density of ATX/lysoPLD-positive cells tended to have a positive correlation with microvessel vascular density (MVD), while it was not correlated with vessel invasion and nodal metastases as well as lymphovascular vessel density (LVD).

Conclusion

Our results suggest that local production of LPA through ATX/lysoPLD may weakly correlate with formation of a depressive lesion and tumor angiogenesis in the early stage of colorectal cancer.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
