Activation of the c-Jun NH2-terminal kinase type 1 (JNK1) signaling pathway is often associated with apoptosis. In this report, we elucidated the role of this kinase in the programmed cell death induced by the nucleoside analogue 9-beta-D-arabinosyl-2-fluoroadenine (F-ara-A). Treatment of ML-1 cells with 3 or 10 microM F-ara-A specifically killed cells in the S-phase of the population. Incorpor...

The infectivity and replication of human (HIV-1), feline (FIV), and murine (LP-BM5) immunodeficiency viruses are all inhibited by several nucleoside analogues after intracellular conversion to their triphosphorylated derivatives. At the cellular level, the main problems in the use of these drugs concern their limited phosphorylation in some cells (e.g., macrophages) and the cytotoxic side effec...

Antiretroviral therapies for HIV-1 infection have become progressively more potent and better tolerated. An important milestone was the 2001 Food and Drug Administration approval of tenofovir di-soproxil fumarate (TDF), a once-daily nucleotide analogue reverse-transcriptase in-hibitor that is available commercially as a single agent (Viread; Gilead Sciences), co-formulated with emtricitabine (T...

A fluorescent nucleobase analogue, 7-aminoquinazoline-2,4-(1H,3H)-dione, is incorporated into a DNA oligonucleotide and senses mismatched pairing by displaying G-specific fluorescence enhancement.

CONTEXT Tumor recurrence is a major issue for patients with hepatocellular carcinoma (HCC) following curative liver resection. OBJECTIVE To investigate the association between nucleoside analogue use and risk of tumor recurrence in patients with hepatitis B virus (HBV)--related HCC after curative surgery. DESIGN, SETTING, AND PARTICIPANTS A nationwide cohort study between October 2003 and S...
