When PLC\/PRF\/5 cells were maintained for 7 days in 30 or 60 \u03bcM DFX, the cell number was decreased by 30\u201360%, little or no \u03b1\u2010fetoprotein (AFP) was produced, and supernatant endpoint dilution titers of hepatitis B surface antigen (HBsAg) were reduced 1\u20132 logs. PLC\/PRF\/5 cells maintained for 7 days without DFX (simultaneous controls) grew to confluence, produced AFP that reached 10\u201360 ng\/ml in the supernate, and the HBsAg titer remained constant or increased 1 log. Similar effects were observed in Hep3B and Hep G2 cells maintained in DFX (except that Hep G2 cells do not produce HBsAg), compared to simultaneous control cells grown in the absence of DFX. The growth of a human embryonic lung fibroblast cell line (WI\u201038) was not significantly inhibited by DFX, although it grew at a slower rate than simultaneous control cells grown without DFX. Subsequent growth in FeSO<jats:sub>4<\/jats:sub>, of PLC\/PRF\/5, Hep3B, and Hep G2 cells that previously had been maintained in DFX did not reverse the effects of DFX. PLC\/PRF\/5 cells were also inhibited when maintained in medium containing equimolar concentrations of DFX and FeCl<jats:sub>3<\/jats:sub>, and in medium containing equimolar concentrations of DFX and FeSO<jats:sub>4<\/jats:sub>,. PLC\/PRF\/5 cells were not inhibited by maintenance in up to 60 \u03bcM of another chelating agent that has a similar affinity for iron, calcium disodium versenate (EDTA). These studies show that DFX inhibits the growth of human hepatocellular carcinoma and hepatoblastoma cell lines regardless of the presence (PLC\/PRF\/5, Hep3B) or absence (Hep G2) of integrated hepatitis B virus DNA. The findings also suggest that the inhibition may have been due to mechanisms other than iron chelation.<\/jats:p>","DOI":"10.1002\/jmv.1890340108","type":"journal-article","created":{"date-parts":[[2007,3,2]],"date-time":"2007-03-02T19:17:12Z","timestamp":1172863032000},"page":"45-50","source":"Crossref","is-referenced-by-count":8,"title":["Inhibition of human hepatocellular carcinoma and hepatoblastoma cell lines by deferoxamine"],"prefix":"10.1002","volume":"34","author":[{"given":"Edward","family":"Tabor","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.
