Project description:bulk sequencing outputs of Caco2 cells after exposure to permeability modifying and permeability rescuing agents. To identify the molecular drivers for methotrexate-induced barrier dysfunction, we conducted RNA sequencing on Caco2 spheroids treated with methotrexate and lactoferrin. Given our observation that barrier function was compromised as early as 4-6 hours after exposure to methotrexate, we isolated RNA from spheroids 4-hour post-treatment to capture the transcriptional events responsible for initiating the processes.

Project description:A summary of the work associated to these microarrays is the following: The need for an integrated view of all data obtained from high-throughput technologies gave rise to network analyses. These are especially useful to rationalize phenomena in terms of how external perturbations propagate through the expression of genes. To address this issue in the case of drug resistance, we constructed Biological Association Networks of genes differentially expressed in cell lines resistant to methotrexate (MTX). Seven cell lines representative of different types of cancer including colon cancer (HT29 and Caco2), breast cancer (MCF7 and MDA-MB-468), pancreatic cancer (MIA PaCa-2), erythroblastic leukemia (K562) and osteosarcoma (Saos-2), were used. The differential expression pattern between sensitive and MTX-resistant cells was determined by microarrays covering the whole human genome and analyzed with the GeneSpring GX software package, v.7.3.1. Genes deregulated in common in the two colon cancer cell lines studied, were subject of Biological Association Networks construction. Dikkopf homolog-1 (DKK1) was a clear node of this network, and functional validations of this target using a siRNA showed a chemosensitization toward MTX. Members of the UDP-glucuronosyltransferase 1A (UGT1A) family formed a network of differentially expressed genes in the two breast cancer cell lines studied. siRNA treatment against UGT1A showed also an increase in MTX sensitivity. Eukaryotic translation elongation factor 1 alpha 1 (EEF1A1) was a gene overexpressed in common among the pancreatic cancer, leukemia and osteosarcoma cell lines, and siRNA treatment against EEF1A1 produced a chemosensitization toward MTX. Biological Association Networks identified DKK1, UGT1As and EEF1A1 as important gene nodes in MTX-resistance. Treatments using iRNA technology against these three genes show chemosensitization toward MTX. Two cell lines are compared, which are Caco2 colon cancer cells sensitive to methotrexate and Caco2 cells resistant to 10e-5M MTX. Six samples are provided, which correspond to triplicates of each cell line. The samples provided were analyzed using the specific software GeneSpring GX.

Project description:The aim of the experiment was to identify the genes whose expression was upregulated at the maintenance phase of premature senescence attained after exposure of human colon cancer C85 cells (or CCCL-1) to 1 micromolar methotrexate for 5 days. Gene expression pattern of C85 cells at the senescence initiation phase attained after exposure to 1 micromolar methotrexate for 48 h, was used as a referral system.

Project description:In an attempt to understand the mode of antiviral action of lactoferrin on SARS-CoV-2 infection, we focused on the effect of lactoferrin on uninfected cells. We decided to use a physiologically relevant cell model of iPSC derived- alveolar epithelial cells (the iAEC2). We specifically focused on antiviral pathway triggered by lactoferrin on treated cells that could explain a cell-mediated effect of lactoferrin on viral replication

Project description:Lactoferrin is a highly multifunctional protein. Indeed, it is involved in many physiological functions, including regulation of iron absorption and immune responses. We use microarrays to study the global genome expression of C. elegans fed with a nutraceutical product based on encapsulated lactoferrin.

Project description:Several epidemiological pieces of evidence on air pollution health effects have notably accelerated in recent years. They have described the relationship between PM2.5 (ambient fine particulate matter of <2.5 μm in diameter) and kidney diseases. Previous research has shown that lactoferrin showed renoprotective effects against some kidney diseases. In the current study, we analyzed the transcriptional profiles of PM2.5 and lactoferrin using RNA sequencing (RNA-seq) and identified the key signaling pathway in the human kidney proximal tubular epithelial cell line (HK-2 cells).
