Inhibition of cancer cell proliferation by Tα1 or Tα1-iRGD.

<p>Tα1 or Tα1-iRGD was added to the cell suspension and incubated for 36 h and counted by MTT assay. Paclitaxel (0.0125 µmol/mL) was set as a positive control. RPMI 1640 was set as a negative control. All data were expressed as the mean ± standard deviation, n = 4. Statistical analyses were performed with Student's t-test, n.s., not significant; *p<0.05; **p<0.01; ***p<0.001.
