Abstract

BACKGROUND: Ligustrazine, active ingredients extracted from the natural herb Ligusticum Chuanxiong Hort, has promising anti-tumor properties on tumor cell lines. However, the potential anti-tumor activity of ligustrazine on colorectal cancer (CRC) cells and the molecular mechanisms have not been elucidated. In this study, we explored the critical functions of ligustrazine on SW480 and CT26 cells at cellular levels. METHODS: CCK-8 assay was performed to analyze the cell viability. Flow cytometry analysis was applied to study cell apoptosis and cell cycle. The expressions of cell apoptosis and cell cycle-associated proteins were conducted by western blot and qRT-PCR analysis. RESULTS: Ligustrazine showed significant inhibitory effects on the proliferation of SW480 and CT26 cells. Ligustrazine induced cell apoptosis was associated with the up-regulation of pro-apoptotic protein and the down-regulation of anti-apoptotic protein in an activated mitochondrial-dependent pathway. And it indicated that ligustrazine induced cell cycle arrest by changing the cell cycle distribution, which leads to cell cycle arrest at the G0/G1 phase. Besides, the ligustrazine-induced cell apoptosis and cell cycle arrest were markedly reversed by pifithrin-α (p53 inhibitor), which suggested that ligustrazine-induced cell apoptosis was achieved by regulating p53-dependent mitochondrial pathway and cell cycle arrest at the G0/G1 phase. CONCLUSIONS: These findings demonstrated that ligustrazine could induce SW480 and CT26 cells apoptosis via a p53-dependent mitochondrial pathway and cell cycle arrest at the G0/G1 phase. Ligustrazine may serve as a potential anti-cancer agent for CRC.

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.
