MetabolomicsCommon Metabolic Pathways Implicated in Resistance to Chemotherapy Point to a Key Mitochondrial Role in Breast Cancer
Cancer cells are known to reprogram their metabolism to adapt to adverse conditions dictated by tumor growth and microenvironment. A subtype of cancer cells with stem-like properties, known as cancer stem cells (CSC), is thought to be responsible for tumor recurrence. In this study, we demonstrated ...

MetabolomicsChanges in L-phenylalanine concentration reflect and predict response to anti-PD-1 treatment combined with chemotherapy in patients with non-small cell lung cancer
Chemotherapy combined with checkpoint blockade antibodies targeting programmed cell death protein (PD-1) has achieved remarkable success in non-small cell lung cancer (NSCLC). However, few patients benefit from long-term treatment. Therefore, biomarkers capable of guiding the optimal therapeutic sel...

ModelsMonro2008 - chemotherapy resistance
The paper describes a model of resistance of cancer to chemotherapy. Created by COPASI 4.25 (Build 207) This model is described in the article: Modelling chemotherapy resistance in palliation and failed cure Helen C. Monro, Eamonn A. Gaffney J Theor Biol. 2009, 257 (2), pp.292 Abstract: Th...

TranscriptomicsSERPINA6, BEX1, AGTR1, SLC26A3, and LAPTM4B are markers of resistance to neoadjuvant chemotherapy in HER2-negative breast cancer
Abstract Introduction Response rates to chemotherapy remain highly variable in breast cancer patients. We set out to identify genes associated with chemotherapy resistance. We analyzed what is currently the largest single-institute set of gene expression profiles derived from breast cancers prior t...

MetabolomicsOGFOD1 enables AML chemo- and nutrient stress resistance by regulating protein synthesis

Acute Myeloid Leukemia (AML) commonly relapses after initial chemotherapy response. We assessed metabolic adaptations in chemoresistant cells in vivo before overt relapse, identifying altered branched-chain amino acid (BCAA) levels in patient-derived xenografts (PDX) and immunophenotypically iden...

TranscriptomicsRNA-Seq of neuroblastoma Th-MYCN mouse model, samples sensitive to chemotherapy, and those with chemotherapy resistance
Some neuroblastoma patients relapse after chemotherapy. Here, a Th-MYCNCPM32 mouse model usually have spontaneously tumours which are sensitive to chemotherapy. By treating mice with consecutive cycles of sublethal cyclophosphamide (CPM) using a personal dose escalation protocol (PDE), resistant tum...

TranscriptomicsGenomic Multivariate Predictors of Response to Adjuvant Chemotherapy in Ovarian Carcinoma: Predicting Platinum Resistance
Purpose: Despite advances in radical surgery and chemotherapy delivery, ovarian cancer is the most lethal gynecologic malignancy. Most of these patients are treated with platinum-based chemotherapies, but there is no biomarker model to guide their responses to these therapeutic agents. We have d...

TranscriptomicsMIcroRNA expression profiling of chemotherapy resistant esophageal adeno- and squamous cell carcinoma cell lines
Chemotherapy resistance adversely impacts the treatment of some individuals with esophageal cancer. Identifying chemotherapy resistance might help tailor clinical treatments. In this study the impact of microRNAs on chemotherapy resistance in esophageal cancer was investigated. We used microarrays t...

ProteomicsVincristine resistance reshapes sphingolipid composition and promotes mitochondrial complex I deficiency in acute myelogenous leukemia
Modifications in sphingolipid (SL) metabolism and mitochondrial bioenergetics are key factors implicated in cancer cell response to chemotherapy, including chemotherapy resistance. Vinca alkaloids such as vincristine (VCR), widely used in cancer treatment, are no exception, as their beneficial actio...

ProteomicsIdentification of proteins deregulated by platinum-based chemotherapy as novel biomarkers and therapeutic targets in non-small cell lung cancer
Platinum-based chemotherapy remains the cornerstone of treatment for most people with non-small cell lung cancer (NSCLC), either as adjuvant therapy in combination with a second cytotoxic agent or in combination with immunotherapy. Resistance to therapy, either in the form of primary refractory dise...
