Table 1. Fold overexpression of transketolase transcripts in colon carcinomas (T1–5) in comparison to their corresponding normal tissues.

	T1	T2	T3	T4	T5
TKT	1	1	1	1	1
TKTL1	1	1	1	1	79
TKTL2	1	−9500	−3	−12	−375

Negative numbers indicate fold downregulation. Results are mean values of three independent experiments.
