(Submitter supplied) A significant proportion of patients with oestrogen receptor (ER) positive breast cancers (BC) develop resistance to endocrine treatments (ET) and relapse with metastatic disease. Bone is the most common metastatic site in ER+ patients, however bone metastases are technically challenging to biopsy and analyse. Difficulties concern both tumour tissue acquisition and techniques for analysis and RNA extractions. more...

(Submitter supplied) Polo-Like Kinase 1 (PLK1), a serine/threonine kinase involved in cell cycle regulation at the G2/M transition, is associated with high-risk neuroblastoma (NB) and unfavorable patient outcome. Recently, we and others demonstrated that PLK1 is a potential drug target in neuroblastoma and reported antitumoral actvity of the PLK1 inhibitor BI2536 in preclinical models of NB. We here analyzed the effects of the ATP-competitive PLK1 inhibitor GSK461364 on typical tumorigenic properties of preclinical in vitro and in vivo models of NB. more...

(Submitter supplied) Here we characterise the response of models of ER-positive breast cancer to treatment with the small molecule MDM2 inhibitor NVP-CGM097, a dihydroisoquinolinone derivative currently evaluated in a phase I clinical trial. We show that NVP-CGM097 reduces tumour cell viability of in vitro and in vivo models of endocrine sensitive, endocrine resistant and palbociclib (CDK4/6 inhibitor) resistant p53 wildtype (p53wt) ER-positive breast cancer. more...

(Submitter supplied) The results from our study have identified two clinically relevant, divergent and druggable pathways (DNA repair and STAT3) that can be targeted in combination to effectively combat drug resistance. We also found that the same pathways that were deregulated in palbociclib-resistant cells were also altered in tumor samples obtained from patients who progressed while on palbociclib and endocrine therapy

(Submitter supplied) Purpose: Resistance to endocrine therapy in estrogen receptor-positive (ER+) breast cancer remains a major clinical problem. Recently, the CDK4/6 inhibitor palbociclib combined with letrozole was approved for treatment of ER+ advanced breast cancer, and other CDK4/6 inhibitors are being investigated in combination with different endocrine treatments. However, the role of CDK4/6 in endocrine resistance and their potential as predictive biomarkers of endocrine treatment response remains undefined. more...

(Submitter supplied) HT induces an OXPHOS metabolic editing of ER+ breast cancers, paradoxically establishing HT-driven self-renewal of dormant CD133hi/ERlo cells mediating metastatic progression, which is sensitive to dual targeted therapy In this study, we demonstrated that CD133hi cells can mediate HT resistance and metastatic progression. Using human luminal breast cancer cell lines we have developed an in vivo model of spontaneous metastatic disease recapitulating what is observed in patients. more...

(Submitter supplied) Therapies targeting estrogenic stimulation in estrogen receptor positive (ER+) breast cancer (BC) reduce mortality, but resistance remains a major clinical problem. Molecular studies have shown few high frequency mutations to be associated with endocrine resistance. In contrast, expression profiling of primary ER+ BC samples has identified several promising signatures/networks for targeting. In this study, the cholesterol biosynthesis pathway was the common upregulated pathway in the ER+ LTED but not ER- LTED cell lines, suggesting a potential mechanism dependent on continued ER expression. more...

(Submitter supplied) While targeted therapies directed against cancer cells have proven effective, their clinical benefit is often limited by acquired resistance. This clinical challenge underscores the importance of uncovering the molecular mechanisms behind resistance in order to develop novel targets and drug combinations that can stop the growth of cancer cells. Two pivotal pathways controlling tumor growth are glucose metabolism and cell cycle. more...
