Use of metabolic imaging to monitor heterogeneity of tumour response following therapeutic mTORC1/2 pathway inhibition. (PubMed, Dis Model Mech) - "An integrated multi-modal imaging workflow was developed to assess the heterogeneity of AZD2014 (mTORC1/2 inhibitor) response in a PTEN-null renal cancer model...Increasing PI3K-AKT inhibition by combining with AZD8186 (PI3Kβ inhibitor) further decreased the control-like metabolic signature, showing PI3K-dependent resistance. This demonstrates that MSI-based workflows yield novel insights into the pharmacodynamic effects of mTORC1/2 inhibition in tumours, which classical biomarkers do not resolve. Coupling these workflows with spatial-omics approaches can deliver greater insights into heterogeneity of treatment response."

Tumor adaptation to PI3K inhibition and its stability increases as a function of time and is overcome by combined inhibiting Bcl2 family proteins (EORTC-NCI-AACR 2024) - "Materials &Methods; Cell culture with cell lines BT474, SKbR3, MCF7 and breast PDXs, drug treatment with PI3K inhibitors BYL-719 (1uM) and AZD8186 (250nM), bulk RNA sequencing. Conclusions; The data suggests that induction of adaptive resistance is in part responsible for the continued persistence of tumor masses after the initial response to targeted therapy but also makes them more sensitive towards Mcl1/Bcl2 inhibitors due to upregulation of an anti-apoptotic program. This can be exploited in a pulsatile combination treatment strategy to circumvent chronic adaptive resistance and improve therapeutic outcomes in patients."

Dual inhibition of MEK and PI3Kβ/δ-a potential therapeutic strategy in PTEN-wild-type docetaxel-resistant metastatic prostate cancer. (PubMed, Front Pharmacol) - " Docetaxel-sensitive and docetaxel-resistant mCRPC cells were treated with selumetinib (MEK1/2 inhibitor), AZD8186 (PI3Kβ/δ inhibitor) and capivasertib (pan-AKT inhibitor) alone and in combination. Our findings on the activity of selumetinib+AZD8186 in PTEN-wt cells and in docetaxel-resistant xenograft mice provide an excellent rationale for a novel therapeutic strategy for PTEN-wt mCRPC patients resistant to docetaxel, in whom, unlike PTEN-loss patients, a clinical benefit of treatment with single-agent PI3K and AKT inhibitors has not been demonstrated. A phase I-II trial of this promising combination is warranted."

β1 integrin mediates unresponsiveness to PI3Kα inhibition for radiochemosensitization of 3D HNSCC models. (PubMed, Biomed Pharmacother) - "Here, we investigated the radiochemosensitizing potential and adaptation mechanisms of four PI3K inhibitors, Alpelisib, Copanlisib, AZD8186, and Idelalisib in eight HNSCC models grown under physiological, three-dimensional matrix conditions. Finally, we demonstrate that targeting of the cell adhesion molecule β1 integrin on top of Alpelisib sensitizes non-responders to radiochemotherapy. Taken together, our study demonstrates the sensitizing potential of Alpelisib and other PI3K inhibitors in HNSCC models and uncovers a novel β1 integrin-dependent mechanism that may prove useful in overcoming resistance to PI3K inhibitors."

Silencing COL8A1 inhibited the malignant characterization. Temozolomide and AZD3759 inhibited COL8A1 expression and cell viability and promoted apoptosis and parthanatos gene expression, which is a target to improve glioma."

Combined inhibition of CDK4/6 and AKT is highly active against the luminal androgen receptor (LAR) subtype of triple negative breast cancer (TNBC) (AACR 2023) - "The purpose of this study was to investigate the most effective combinations of inhibitors of CDK4/6 (palbociclib), AR (enzalutamide), and PI3K-AKT (alpelisib/capivasertib) against preclinical models of LAR TNBC...In MDA-MB-453 cells, palbociclib-induced phosphorylation of AKT substrates was suppressed by treatment with capivasertib but not with alpelisib alone or with the PI3Kβ/δ inhibitor AZD8186, suggesting that the compensatory activation of AKT was due to a mechanism independent of the PI3K isozymes...Further investigation of the mechanisms of adaptive activation of AKT upon blockade of CDK4/6 in TNBC cells are in progress. In sum, addition of an AKT inhibitor, but not PI3K inhibitors, to palbociclib suppressed the rebound activation of AKT following treatment with the CDK4/6i, supporting a testable therapeutic strategy in LAR TNBC with intact Rb."
