[Elevated levels of TFF3 in endometrial cancer patients]
Aim:
Trefoil peptides are a family of small proteins that are expressed in a site-specific fashion by certain epithelial tissues. These peptides might be used as markers for neoplastic uterine disease.
Design:
Experimental study.
Setting:
Department of Obstetrics and Gynaecology, University Hospital, Medical Faculty, Palacký University, Olomouc; Department of Laboratory Biochemistry, Central Moravian Hospital Trust, Member of Agel holding, Prostějov.
Methods:
During the time period from 2012 to 2015 eighty-nine women underwent hysteroscopy and endometrial biopsy for postmenopausal bleeding. Fifty three patients, at the age of (mean ± standard deviation) 63,4 ± 9,5 (33-80) years were diagnosed with endometrial cancer, six patients at the age of 62,9 ± 6,4 (55-74) years were diagnosed with endometrial hyperplasia and thirty patients at the age of 63,3 ± 9,3 (48-62) years diagnosed with endometrial atrophy represented control group. At the day of surgery the venous blood was sampled and subsequently examined for the levels of TFF1, TFF2 and TFF3.
Results:
TFF3 levels were significantly higher in patients with endometrial carcinoma but not in endometrial hyperplasia subgroup. The levels of TFF1 and TFF2 were not different in selected histopathological subgroups.
Conclusion:
We have shown elevated levels of TFF3 but not of TFF1 and TFF2 in patients with endometrial cancer. TFF1, TFF2 and TFF3 levels were not elevated in patients with endometrial hyperplasia.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
