Low red blood cell levels of deglycating enzymes in colorectal cancer patients

Table 2 Red blood cell levels of Glyoxalase I and fructosamine-3-kinase activity in controls, adenoma and tumor-bearing patients (mean ± SD)

	Glyoxalase I	FN3K
Controls (n = 11)	0.173 ± 0.25	29.05 ± 14.6
Adenomas (n = 33)	0.128 ± 0.19a	38.6 ± 31.7b
Tumors (n = 16)	0.022 ± 0.01a	19.55 ± 6.4b

^a,bP < 0.05, Tukey’s test. The glyoxalase enzymatic activity is expressed as mmol/min per milliliter of red blood cells and the enzymatic activity of FN3K is expressed as pmol/min per milliliter of red blood cells. FN3K: Fructosamine-3-kinase.
