Thymidine 107-116 transferrin receptor Homo sapiens 31-51 2413049-6 1985 It was subsequently found that inhibition of the M2 subunit of ribonucleotide reductase in CCRF-CEM cells with 5 X 10(-5) M hydroxyurea, which is not an iron chelator, also enhanced TfR expression, as did thymidine and cytosine arabinoside, which have different enzyme targets. Thymidine 205-214 transferrin receptor Homo sapiens 182-185 19233349-9 2009 Statistically significant correlation between proliferation assessed as (3)H-thymidine incorporation and expression of activation markers was found in the case of CD25, CD27, CD38, CD152, CD71, still only in samples with higher proliferation activity (SI>25). Thymidine 77-86 transferrin receptor Homo sapiens 188-192
