英文摘要

Dietary components play an important role in cancer prevention. Many ingredients from apples have been proven to have anti-tumor potency. We thus made low molecular weight apple polysaccharides (LMWAP) and evaluated the effects of it on colorectal cancer (CRC). The effects of LMWAP on human colon carcinoma cells (HT-29) were evaluated using a microarray. Then, cell-cycle distribution was measured by flow cytometric analysis. A colitis-associated colorectal cancer mouse model was used to assess the effect of LMWAP on in vivo CRC prevention. Treatment of HT-29 cells with LMWAP resulted in 333 genes expression over cutoff values (>= 2-fold). Further analysis demonstrated that pathways of cell cycle were mainly influenced. At the concentrations from 0.001 to 0.1 mg/mL, LMWAP induced a G(0)/G(1) phase block in HT-29 cells in a dose-dependent way. In vivo studies revealed that administration of LMWAP could protect ICR mice against CRC effectively. The results of Western blot suggested LMWAP induced cell-cycle arrest in a p53 independent manner. These data indicate that LMWAP could inhibit the development of CRC through affecting cell cycle, and it has potential for clinical prevention for colon cancer.
