Transcriptional profiling of ICL670 treated K562 cells

ABSTRACT: Iron plays a central role in the regulation of many cellular functions. Dysregulation of its metabolism leads an iron overload situation and iron depletion leads to an inhibition of cell proliferation. Recent reports demonstrated that ICL670 (Novartis) acts as a potent NF-kappa-B inhibitor and improves hematological data in a subset of MDS patients (Cilloni et al, Haematologica, s1: 238, 2007). However, the precise mechanism of anti-cancer effect of ICL670 is still uncertain. To evaluate the effect of ICL670, and to identify the moleclular pathways responsible for the observed reduced transfusion requirement during chelation therapy, we performed gene expression profiling to focus on the pathway involved in the anti-cancer effect of ICL670.

Iron Chelators Treatment on DMS-53 Human Lung Cancer Cell

Project description:The molecular role of iron in gene expression remains poorly characterized. Moreover, the alterations in global gene expression after iron chelation remains unclear and are important to assess for understanding the molecular pathology of iron-depletion and the biological effects of iron chelators. We assessed the effect on whole genome gene expression of two iron chelators (desferrioxamine and Dp44mT). These studies are important for understanding the molecular and cellular effects of iron-depletion.

Efficacy of Preoperative Intravenous Iron in Anaemic Colorectal Cancer Surgical Patients

Project description:Iron deficiency anaemia is a common condition among colorectal surgical patient. Untreated anaemia would lead to increase in blood transfusion, surgical complications and mortality. Treatment with oral iron sulphate is poorly tolerated due to side effects. Intravenous iron supplement provides an alternative way to rapidly replace iron deficit during the preoperative period among surgical patients. Evidence is growing for its effect in rising hemoglobin level and reducing blood transfusion, at the same time supporting its safety profile. The investigators plan for a single-centered, randomized controlled trial to examine the effect of intravenous iron compared to standard care in terms of hemoglobin level/serum ferritin increment, need for blood transfusion, duration of hospital stay, quality of recovery and surgical complication rate, as well as safety profile among colorectal cancer surgical patients in Hong Kong. The investigator propose the following pilot RCT for exploring the effect size and study process in conducting the above-mentioned large-scale RCT.

Iron Chelators Treatment on MCF-7 Human Breast Cancer Cell

Project description:Iron-deficiency affects 500 million people, yet the molecular role of iron in gene expression remains poorly characterized. Moreover, the alterations in global gene expression after iron chelation remains unclear and are important to assess for understanding the molecular pathology of iron-deficiency and the biological effects of iron chelators. We assessed the effect on whole genome gene expression of two iron chelators (desferrioxamine and 2-hydroxy-1-napthylaldehyde isonicotinoyl hydrazone) that have markedly different permeability properties. Sixteen genes were significantly regulated by both chelators, while a further 50 genes were regulated by either ligand. Most of the genes identified in this study have not been previously described to be iron-regulated and are important for understanding the molecular and cellular effects of iron-deficiency.

RNA sequencing of human macrophages treated with iron chelator deferiprone (DEF), with and without lipopolysaccharide (LPS)

Project description:In order to identify transcript changes in response to DEF , we used human macrophages with or without DEF treatment. In order to study the effect of iron chelation on LPS-polarized macrophage transcriptome, we exposed DEF-treated or control macrophages to short time exposure to LPS. We then performed whole-genome transcriptome sequencing by RNA-sequencing (RNA-seq).

Transcript Analysis of E. coli ATCC 35218 suggest a Role of cranberry Juice in Inhibiting the growth of E. coli

Project description:Several different mechanisms have been proposed to explain the possible role of cranberries, cranberry juice, and cranberry extracts in inhibiting bacterial growth. In this report, we showed that Escherichia coli showed slower growth rate in response to the presence of cranberry juice in the growth media. By compareing the global transcript profiles, significant modulation of several genes of E. coli grown in LB broth with 10% cranberry juice were identified and provided identification of the potential mechanisms involved in the inhibitory effects of cranberry juice. The results presented clearly demonstrate that the inhibitory effect on bacterial growth observed in the presence of cranberry juice/extracts is primarily a result of the iron chelation capacity of PACs and direct disruption of metabolic enzymes. The results are discussed with a focus on the genes associated with iron chelation capability. Keywords: growth inhibition of cranberry juice

Iron chelation therapy elicits innate immune control of metastatic ovarian cancer

Project description:Iron accumulation in cancer cells contributes to malignant progression and chemoresistance. While disrupting this process can influence various hallmarks of cancer, the immunomodulatory effects of chelating iron in tumors remain undefined. Here, we report that treatment with deferiprone, an FDA-approved iron chelator, elicits innate immune responses that control metastatic ovarian cancer. Deferiprone reprogrammed ovarian cancer cells towards an immunostimulatory state characterized by enhanced production of type I interferon (IFN) and surface overexpression of molecules that activate natural killer (NK) cells. Mechanistically, this reprogramming was driven by innate sensing of mitochondrial DNA in the cytosol and concomitant activation of nuclear DNA damage responses evoked upon iron chelation. Deferiprone administration synergized with chemotherapy and prolonged the survival of mice bearing metastatic ovarian cancer by bolstering intratumoral NK cell infiltration and type I IFN responses. Iron chelation may represent an alternative immunotherapeutic approach for malignancies that are normally refractory to T cell-centric modalities.
