Allicin inhibits cell polarization, migration and division via its direct effect on microtubules
Abstract
Allicin (diallyl thiosulfinate) is a major biologically active component of garlic that is known to inhibit cell proliferation and induce apoptosis. The effects of allicin are attributed to its ability to react with thiol groups. However, the mechanism underlying the cytostatic activity of allicin, as well as the identity of the relevant subcellular targets, are not known. In the present study, we found that the effects of allicin on cell polarization, migration, and mitosis are similar to the effects of microtubule‐depolymerizing drugs such as nocodazole. Moreover, treatment of cultured fibroblasts with micromolar doses of allicin results in microtubule depolymerization in cells within minutes of its application, without disrupting the actin cytoskeleton or inducing direct cytotoxic effects. Furthermore, allicin blocks the polymerization of pure tubulin in vitro in a concentration‐dependent manner, suggesting that it acts directly on tubulin dimers. Sulfhydryl (SH)‐reducing reagents such as 2‐mercaptoethanol and dithiothreitol abolish the effect of allicin on microtubule polymerization. Thus, allicin is a potent microtubule‐disrupting reagent interfering with tubulin polymerization by reaction with tubulin SH groups. Cell Motil. Cytoskeleton 2007. © 2007 Wiley‐Liss, Inc.

Allicin prevents cell proliferation by targeting tubulin that shapes the mitotic spindle and thus inhibits cell division.
“Several studies reported the activity of allicin in preventing cell proliferation [81] by targeting tubulin that shapes the mitotic spindle and thus inhibits cell division [82].”

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.
