- Description
- Knockdown of PTEN in trastuzumab sensitive HER2 breast cancer BT474 cells induced trastuzumab resistance. PTEN null cells treated with PI3K inhibitor LY294002 also did not show substantial inhibition, but co-treatment with trastuzumab and LY294002 induced growth inhibition comparable to trastuzumab alone in normal BT474 cells. BT474 mouse xenograft tumors were injected with PTEN antisense (AS) oligonucleotides and this resulted in trastuzumab resitance. Co-treatment of PTEN AS tumor mice with LY294002 and trastuzumab inhibited tumor growth in comparison to PTEN AS tumors treated with trastuzumab or LY294002 alone.
