HSP70 expressions in laryngeal carcinoma xenograft were down-regulated by HSP70 antisense oligos. (a) shows HSP70 expression in implantation tumor treated with random oligos. (b) shows HSP70 expression in implantation tumor treated with HSP70 antisense oligos. (c-d) shows the representative H&E images in group random negative controls and group antisense; Western blot shows hsp70 expressions in group antisense and group random (e). HSP70 expression is significantly reduced in the antisense group comparing with random group.
