Abstract Microscaled proteogenomics was deployed to probe the molecular basis for differential response neoadjuvant carboplatin and docetaxel combination chemotherapy triple-negative breast cancer (TNBC). Proteomic analyses of pretreatment patient biopsies uniquely revealed metabolic pathways, including oxidative phosphorylation, adipogenesis, fatty acid metabolism, that were associated with resistance. Both proteomics transcriptomics sensitivity marked by elevation DNA repair, E2F targets,...
Abstract Transcriptionally active ESR1 fusions (ESR1-TAF) are a potent cause of breast cancer endocrine therapy (ET) resistance. ESR1-TAFs not directly druggable because the C-terminal estrogen/anti-estrogen–binding domain is replaced with translocated in-frame partner gene sequences that confer constitutive transactivation. To discover alternative treatments, mass spectrometry (MS)–based kinase inhibitor pulldown assay (KIPA) was deployed to identify kinases upregulated by diverse...
Abstract Endocrine therapies (ET) with cyclin-dependent kinase 4/6 (CDK4/6) inhibition are the standard treatment for estrogen receptor-α-positive (ER+) breast cancer, however drug resistance is common. In this study, proteogenomic analyses of patient-derived xenografts (PDXs) from patients 22 ER+ cancer demonstrated that protein kinase, membrane-associated tyrosine/threonine one (PKMYT1), a WEE1 homolog, estradiol (E2) regulated in E2-dependent PDXs and constitutively expressed when growth...
NF1 is a key tumor suppressor that represses both RAS and estrogen receptor-α (ER) signaling in breast cancer. Blocking pathways by fulvestrant (F), selective ER degrader, together with binimetinib (B), MEK inhibitor, promotes regression NF1-depleted
Triple-negative breast cancer (TNBC) constitutes 10%-15% of all tumors. The current standard care is multiagent chemotherapy, which effective in only a subset patients. original objective this study was to deploy mass spectrometry (MS)-based kinase inhibitor pulldown assay (KIPA) identify kinases elevated non-pCR (pathologic complete response) cases for therapeutic targeting. Frozen optimal cutting temperature compound-embedded core needle biopsies were obtained from 43 patients with TNBC...
Abstract Background: Multi-omics analysis is widely used in cancer diagnosis, prognosis and prediction of treatment response. Here we introduce the use targeted proteomics coupled with NGS as tools to assess oncogenic alterations along quantitative protein expression patients mCRC. Our panel included proteins that are antibody drug conjugates (ADCs) targets (ERBB 1-4, TROP2, CEACAM5 etc.) well involved sensitivity ADC payload (SLFN11, efflux pump, TOP1 etc.). Methods: The HORIZON III trial...
Abstract NF1 is a key tumor suppressor that represses both RAS and estrogen receptor-α (ER) signaling in breast cancer. Blocking pathways by fulvestrant (F), selective ER degrader (SERD), together with binimetinib (B), MEK inhibitor, promotes regression NF1-depleted ER+ models. We aimed to establish approaches determine how protein levels impact B+F treatment response improve our ability identify sensitive tumors. examined panel of PDX models DNA mRNA sequencing found more than half these...
Sixteen patient-derived xenografts (PDXs) were analyzed using a mass spectrometry (MS)-based kinase inhibitor pull-down assay (KIPA), leading to the observation that death-associated protein 3 (DAPK3) is significantly and specifically overexpressed in triple-negative breast cancer (TNBC) models. Validation studies confirmed enrichment of DAPK3 protein, both TNBC cell lines tumors, independent mRNA levels. Genomic knockout
