Abstract

The use of the organic cosolvents tetrahydrofuran and dimethylsulfoxide was found to be unsuitable for prostate tunor cell cultures because of solvent cytotoxicity and the poor solubility and instability of lycopene. For example, the half‐life of lycopene in organic/aqueous solution was found to be less than 2 h. Therefore, a micellar preparation of lycopene was developed for the solubilization and stabilization of lycopene in cell culture media. Neither the micelles themselves nor lycopene solubilized in micelles at concentrations up to 10 μg/mL. in the cell culture media produced cytotoxicity or inhibition of cell proliferation in either LNCaP human prostate cells or Hs888Lu human lung cells. Lycopene solubilized in micelles was stable for at least 96 h under standard cell culture conditions so that a constant lycopene supply could be provided to the cells. During the culture process, lycopene was taken up by LNCaP cells and reached a plateau at approximately 12 h. Micelles provide a convenient, inexpensive, and nontoxic vehicle for dissolving and stabilizing carotenes such as lycopene in tissue culture media and then delivering them to cells growing in culture.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
