Biological Activity for Floxuridine

Floxuridine is an antineoplastic antimetabolite. Exhibits antiproliferative activity; inhibits thymidylate synthetase and disrupts DNA replication in human cells. Induces double-strand DNA breaks; activates ATR and ATM signaling pathways. Induces phosphorylation of Chk1 and Chk2 in OVCAR-8 and SKOV3ip ovarian cancer cell lines.

Cancer Metabolism Poster

Cancer Metabolism Poster

Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the main targets for cancer metabolism researchers. Genetic changes and epigenetic modifications in cancer cells alter the regulation of cellular metabolic pathways. These distinct metabolic circuits could provide viable cancer therapeutic targets.

Cell Cycle & DNA Damage Repair Poster

Cell Cycle & DNA Damage Repair Poster

In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.

Pathways for Floxuridine

Apoptosis Signaling Pathway

Apoptosis Signaling Pathway

Apoptosis is a physiological process for cell death that is critical during aging and development. It may also be referred to as cell 'suicide'. Apoptosis can be triggered by events both inside and outside of the cell.
p53 Signaling Pathway

p53 Signaling Pathway

p53 signaling plays an important role in the co-ordination of the cellular response different types of stress such as DNA damage and hypoxia. The downstream signals lead to apoptosis, senescence and cell cycle arrest.
