The mechanism of PPS accelerating IEC-6 cells migration was also researched with gene-chip technique. The Altas Clontech Rat cDNA Chip which consisted of 1176 spots representing different functional categories such as heat shock/stress, cell cycle, transcription factors, hormones, metabolism, etc was used. Result showed in cell migration model of IEC-6 cell line, compared with control group, expression of 38 genes in total 1176 genes varied in cells treated by PPS, including 21 genes up-regulated and 17 genes down-regulated. Date analyze showed the mechanism of PPS accelerating IEC-6 cells migration mainly related with promoting the numbers and activity of cellular ion channel, especially 〓 channel.
