Arsenic trioxide inhibits lung metastasis of breast cancer by suppression of TP53, TGFβ and TNFα signaling pathways

Project description:Metastasis is the main cause of mortality of breast cancer. To explore the mechanisms of arsenic trioxide (ATO) in inhibition of breast cancer metastasis, ATO regulated genes in breast cancer MDA-MB-231 and LM2-4175 cells were studied. After data analysis, ATO regulated genes were involved in TP53, TGFβ and TNFα signaling pathways. Furthermore, TGFβ and TNFα activated genes in breast cancer MDA-MB-231 cells were studied.

Aberrantly expressed genes in HaCaT keratinocytes chronically exposed to arsenic trioxide

Project description:The purpose of this study is to search for aberrant genes in HaCaT keratinocytes after chronic exposure to arsenic trioxide. The objective of the investigation was to discover the mechanism of arsenic carcinogenicity in human epidermal keratinocytes. We hypothesize that a combined strategy of DNA microarray, qRT-PCR and gene function annotation will identify aberrantly expressed genes in HaCaT keratinocyte cell line after chronic treatment with arsenic trioxide. HaCaT cells were chronically exposed to 0.5M-BM-5g/mL arsenic trioxide (As2O3) up to 22 passages and RNA was extracted. Microarray data analysis identified 14 up-regulated genes and 21 down-regulated genes in response to arsenic trioxide Two experimental groups: 1. The treatment group was sub-cultured up to passage 22 to establish a chronic exposure state. 2. The passage control group was also sub-cultured up to 22 passages but with no exposure to arsenic trioxide. 4 technical replicates with 3 replicates making a total of 8X3 =24 samples HaCat Cell untreated (passage control): 1. H1_H001, H1_H002, H1_H003 2. H2_ H004, H2_H005, H2_H006 3. H3_ H007, H3_H008, H3_H009 4. H4_ H010, H4_H011, H4_H012 HaCat Cell treated with 0.5M-BM-5g/ml of arsenic trioxide: 5.

A4_H022, A4_H023, A4_H024 Cell Type: Human Skin Keratinocyte: 1.5 M-CM-^W105 HaCaT cells were cultured in 7.5 ml of complete DMEM containing 10% Fetal Bovine Serum (FBS) and 1% penicillin, streptomycin in T-25 culture plate. Cells were incubated in a humidified atmosphere with 5% CO2 at 37 M-BM-:C. The treatment groups were exposed to 0.5M-BM-5g/mL As2O3 (equivalent to LC 0.5), and passaged at 90% confluent. Total RNA was extracted from 4 technical replicates of unexposed HaCaT cells and HaCaT cells chronically exposed to arsenic trioxide up to passage 22 using RNA STAT-60 (TEL-TEST, INC, Friendswood, TX, USA).

Identification of differentially expressed genes by rapid induction of PML/RARa degradation using arsenic trioxide in NB4 cells

Project description:Acute promyelocytic leukemia (APL) is characterized by the specific chromosome translocation t(15;17) that generates the promyelocytic leukemia/retinoic acid receptor-α (PML/RARα) fusion gene. Arsenic trioxide has been intensively reported to directly and rapidly degrade the PML/RARα fusion protein. Here, we treated NB4 cells (a widely used APL cell line) with arsenic trioxide and performed RNA-seq analysis to identify differentially expressed genes upon arsenic trioxide treatment.

TP53 wild type cells are resistant to arsenic trioxide induced dynamic transcriptional changes

Project description:Previous and our results show that cells with mutant p53 are more sensitive to arsenic trioxide (ATO) induced cell growth inhibition. To explore the underling mechanisms, we conduct a detailed analysis of the globe transcriptional profiles of ATO regulated genes in breast, colon and lung cancer cells with different p53 status. We find p53 wild type cells are resistant to ATO induced globe dynamic transcriptional changes, thus resistant to ATO induced cell growth inhibition. P53 inhibitor PFTα releases p53 mediated transcriptional resistance and increases the sensitivity of ATO in p53 wild type tumor cells.

Comparison of gene expression profile of naive versus arsenic trioxide resistant acute promyelocytic leukemia cell line NB4

Project description:The aim of this study was to gain insight into the potential mechanism of resistance to arsenic trioxide (ATO). The gene expression profile of naive (NB4) (Acute promyelocytic leukemia (APL) cell line and one of its in house generated ATO resistant sub clone (NB4-VM-AsR1) was done using whole genome microarray and compared to generate the differential expression profile which will give insight into the mechanisms of ATO resistance in APL. Agilent one-color experiment,Organism: Human ,Agilent Whole Genome Human 4x44k (AMADID: 014850) , Labeling kit: Agilent Quick-Amp labeling Kit (p/n5190-0442) naive versus arsenic trioxide resistant acute promyelocytic leukemia cell line NB4
