MAF amplification licenses ERα through epigenetic remodelling to drive breast cancer metastasis.

MAF amplification increases the risk of breast cancer (BCa) metastasis through mechanisms that are still poorly understood yet have important clinical implications. Oestrogen-receptor-positive (ER) BCa requires oestrogen for both growth and metastasis, albeit by ill-known mechanisms. Here we integrate proteomics, transcriptomics, epigenomics, chromatin accessibility and functional assays from human and syngeneic mouse BCa models to show that MAF directly interacts with oestrogen receptor alpha (ERα), thereby promoting a unique chromatin landscape that favours metastatic spread.

The CDK4/6 Inhibitor Palbociclib Inhibits Estrogen-Positive and Triple Negative Breast Cancer Bone Metastasis In Vivo.

CDK 4/6 inhibitors have demonstrated significant improved survival for patients with estrogen receptor (ER) positive breast cancer (BC). However, the ability of these promising agents to inhibit bone metastasis from either ER+ve or triple negative BC (TNBC) remains to be established. We therefore investigated the effects of the CDK 4/6 inhibitor, palbociclib, using in vivo models of breast cancer bone metastasis.

The Second Nutrition and Cancer Networking Meeting Nutrition and Breast Cancer: Translating Evidence into Practice.

The 2 Nutrition and Cancer Networking Meeting '' was held at Newcastle University in May 2022, with support from the Nutrition Society and British Association for Cancer Research. The first meeting in this series was held in Sheffield in 2019. The aim of this joint meeting was to bring together researchers with an interest in nutrition and breast cancer, with the programme spanning topics from risk and prevention to nutrition during treatment and beyond.

CDK4/6 inhibitors: A potential therapeutic approach for triple negative breast cancer.

Triple negative breast cancer (TNBC) cells lack expression of the estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER-2). Thus, TNBC does not respond to hormone-based therapy. TNBC is also an aggressive subtype associated with poorer prognoses compared to other breast cancers.

Adoption of adjuvant bisphosphonates for early breast cancer into standard clinical practice: Challenges and lessons learnt from comparison of the UK and Australian experience.

International guidelines recommend adjuvant bisphosphonates (BPs) for post-menopausal women with early breast cancer to reduce recurrence and mortality. However, globally, wide variation exists in their adoption. In the UK, adjuvant BPs were a recommendation in the breast cancer Clinical Reference Group service specification and were included as a priority for implementation by the national oncologists group UK Breast Cancer Group in November 2015, promoting national uptake, guidance and funding arrangements.
