The antifolate pemetrexed induces innate tolerance in human macrophages

ABSTRACT: Macrophage phenotypic and functional heterogeneity derives from tissue-specific transcriptional signatures shaped by the local microenvironment. GM-CSF drives the generation of human monocyte-derived macrophages with a potent pro-inflammatory activity upon stimulation. One-carbon metabolism (OCM) is a complex network of biosynthetic pathways that includes de novo biosynthesis of purines and thymidylate, amino acid metabolism, and methylation reactions. We explored the molecular impact of blocking OCM with the anti-folate pemetrexed (PMX) on the gene expression profile in LPS-activated GM-CSF-primed human monocyte derived macrophages. The specificity of blocking OCM with the anti-folate PMX was demonstrated with folinic acid.

The role of the antifolate methotrexate in LPS response in human macrophages

Project description:Macrophage phenotypic and functional heterogeneity derives from tissue-specific transcriptional signatures shaped by the local microenvironment. M-CSF drives the generation of human monocyte-derived macrophages with a potent anti-inflammatory activity upon stimulation. One-carbon metabolism (OCM) is a complex network of biosynthetic pathways that includes de novo biosynthesis of purines and thymidylate, amino acid metabolism, and methylation reactions. We explored the molecular impact of blocking OCM with high-doses of the anti-folate methotrexate (MTX) on the gene expression profile in M-CSF-primed human monocyte derived macrophages during LPS activation.

Pemetrexed alters inflammatory profile in EA.hy 926 cells grown under low-folate conditions.

Project description:Pemetrexed is an antifolate drug used in the treatment of lung cancer. EA.hy 926 cells grown under low (Lo) and normal (Hi) folate conditions were treated with PMX. Microarray analysis was used to examine changes in gene expression due to PMX treatment. Hi and Lo cells were grown to confluence and maintained in fresh medium for 24 hours prior to treatment with 0.5uM PMX for 48 hours.

Association of Antifolate Response Signature Status and Clinical Activity of Pemetrexed-Platinum Chemotherapy in Non-Small Cell Lung Cancer - The Piedmont Study

Project description:The Piedmont study is a prospectively designed retrospective evaluation of a new 48-gene antifolate response signature (AF-PRS) in patients with locally advanced/metastatic NS-NSCLC treated with pemetrexed-containing platinum doublet chemotherapy (PMX-PDC). The study tested the hypothesis that the AF-PRS selects for patients with NS-NSCLC that preferentially respond to PMX-PDC, with a goal of providing clinical support for AF-PRS as potential diagnostic test. Overall, 53% of patients were AF-PRS(+), which was associated with extended PFS, but not OS, vs. AF-PRS(-) (16.6 vs. 6.6 mo; p = 0.025). In patients who were Stage I-III patients at time of treatment, PFS, but not OS, was further extended in AF-PRS(+) vs. AF-PRS(-) (36.2 vs. 9.3 mo; p = 0.03). A complete response (CR) to therapy was noted in 14 of 95 patients. AF-PRS(+) preferentially selected a majority (79%) of CRs, which were evenly split between patients Stage I-III (6 of 7) and Stage IV (5 of 7) at time of treatment. AF-PRS identified a significant population of patients with extended survival and/or clinical response following PMX-PDC treatment. AF-PRS may be a useful diagnostic test for patients indicated for systemic chemotherapy, especially when determining the optimal PDC regimen for locally advanced disease.

Transcription profiling by array of mesothelioma pre- and post-resistance biopsies in order to determine a resistance signature to pemetrexed/carboplatin treatment

Project description:Pemetrexed, a multi-folate inhibitor combined with a platinum compound is the first-line treatment of malignant mesothelioma, but median survival is still one year. Innate and acquired resistance to pemetrexed is common, but its biological basis is obscure. Here we report for the first time a genome-wide profile of acquired resistance in the tumour from an exceptional case with advanced pleural mesothelioma and almost six years survival after 39 cycles of second-line pemetrexed/carboplatin treatment.

Effect of JAK inhibitors Upadacitinib or Baricitinib on gene expression during human monocyte-derived macrophage differentiation

Project description:Macrophage phenotypic and functional heterogeneity derives from tissue-specific transcriptional signatures shaped by the local microenvironment. GM-CSF drives the generation of human monocyte-derived macrophages with a potent pro-inflammatory activity upon stimulation. Janus Kinase (JAK) inhibitors are small molecules that reversibly inhibit JAK activity and their subsequent intracellular signaling and have become the treatment of choice for diseases with an inflammatory or immune basis. We explored the molecular impact of blocking GM-CSFR-JAK2-STAT5 axis with the Janus Kinase (JAK) inhibitors Upadacitinib or Baricitinib on the gene expression profile in GM-CSF-primed human monocyte derived macrophages.
