TKTL1 and ovarian cancer: Moreover, a statistically significantly higher level of mRNA expression was found in the ovarian cancer group compared to the control group for the transferrin receptor (CD71), H2A.X and ADH1A. On the other hand, the differences in the mRNA expression for TKT and TKTL1 were at a statistically significant level, with p = 0.003 and p = 0.016, respectively Table 3 and Table 4, Figure 1.
