Author Correction: Every step of the way: integrins in cancer progression and metastasis

In the originally published article, pertuzumab was incorrectly described as an anti-PI3K therapy in the section ‘Integrins in anticancer therapy’. The sentence should read ‘In mouse mammary tumour models, increased collagen levels and increased β1 integrin and SRC activity have been demonstrated to accompany, and promote, combined resistance to anti-human epidermal growth factor receptor 2 (HER2; also known as ERBB2) (trastuzumab and pertuzumab) and anti-PI3K (buparlisib) therapies164.’ This has now been corrected in all versions of the original article.
