Primary Institution: Lehigh University and Hahnemann University School of Medicine
Hypothesis
The predominance of embryonic (basic) forms would indicate that the enzyme in the fluid is mostly of tumour cell origin.
Conclusion
The study found that the majority of a-L-fucosidase activity in ascites fluid is derived from the host rather than the tumor cells.
Supporting Evidence
- The ascites fluid contained 32.6 units of a-L-fucosidase activity per ml.
- 88% of the recovered ascites fluid a-L-fucosidase activity is associated with acidic isoelectric forms.
- 76% of the enzyme activity from the tumor cell lysates is associated with basic isoelectric forms.
Takeaway
The researchers looked at a special enzyme in fluid from tumor cells and found that most of it actually comes from the body, not the tumor.
Methodology
The study involved injecting tumor cells into mice, collecting ascites fluid, and analyzing the a-L-fucosidase activity using isoelectric focusing.
Limitations
The study found that isoelectric focusing of ascites fluid is not a useful approach for identifying tumor-derived a-L-fucosidase.
Participant Demographics
Adult outbred female Swiss-Webster mice were used in the study.
