IOI-42 promoted the sensitivity of rectal cancers to irradiation in vivo. a Flow chart for the in vivo radiation experiment. b Growth curve of transplanted rectal cancer volume for different treatments. c Immunoreactive score for Akt activation in vivo after different treatments (below is the representative pictures of activated Akt staining of radiation plus IOI-42, radiation alone, and IOI-42 alone). d Representative pictures of TUNEL assay for different treatments. (I is the short form for IOI-42, R is the short form for irradiation, IRS is the short form for immunoreactive score)
