Project description:The molecular mechanism of Cr6+ carcinogenicity is not well understood. Studies advocate a key involvement of the altered cytogenomics and dysregulated pathways in Cr6+ toxicity. However, the dissimilarity in expression of genes and pathways in cells transformed by Cr6+ has led us to supplement more data on the subject. We report here genomics of cells transformed after acute exposure to submicromolar (0.01or1µM) test doses of Cr6+; the non-cytotoxic submicromolar test concentrations transformed the mammalian cells; the characteristic gain of anchorage independent growth potential was demonstrable in soft agar assay. C3H10T1/2 and BALB/c 3T3 cell transformation assay has been used which is established in literature as the in vitro carcinogenesis test system. Gene expression profile of the transformed cells was found to be dysregulated at both the toxicant doses. PARP1 gene was significantly up regulated and SFN, MTIF2, IRGQ, RAVER2, SLC2A6, MLLT3, EPB4.1L3, JAK1, RALGPS1, EXTL3, PRMT6, PREB, SERPINE1, MORC4 genes were significantly down regulated commonly at two test concentrations. These genes were found to be involved in tumour suppression, DNA repair, cell cycle control, energy metabolism and biosynthesis.Cr6+ also induced MAPK signalling via ERK phosphorylation. Activation of ERK signalling, dysregulation of gene expressions, and cell transformation was prevented by alpha lipoic acid (LA) in equimolar concentrations. The acute exposure to submicromolar concentrations of Cr6+ can induce cell transformation and gene dysregulations in mammalian cell. The influenced genes are crucial for progression of Cr6+ toxicity and their mitigation by LA shows critical role of redox reactions in Cr6+ toxicity.

Project description:In our earlier study, thiourea has been shown to improve the growth of rice and reduce the arsenic load from aerial parts of the seedlings. We have also shown the applicability of thiourea to delineate the redox regulatory mechansisms under arsenic stress in rice. To move further, present microarray was performed to reveal the involvement of overall gene and regulatory netwrok under arsenic with/without thiourea treatment in rice.

Project description:To reveal the molecular mechanism underling necrotic neuronal cell death caused by norephedrine, we examined alteration of gene expression profile during norephedrine exposure in human neuroblastoma SH-SY5Y cells. The alteration of gene expression during norephedrine exposure (3 mM, 0,2 and 6 hours) in differentiated SH-SY5Y cells was examined.
Project description:Recombinant adenovirus expressing Chandipura virus nucleo (N) protein (ADN) induces cell lysis in infected cells. In order to find out the pathway involved in cell lysis, we have employed micro array experiment using custom whole genome microarray 4x44k designed by Genotypic Technology private limited, India (AMADID 025085) to identify the genes which involved in apoptotic, cell cycle, signalling etc. AD 293 cells were infected with ADN and the total RNA was purified at 3 and 6 h post infection (PI). In control experiment, the total RNA was purified at 6 h PI from uninfected AD 293cells and cells infected with recombinant adenovirus without N gene. Gene expression profile of these samples was analysed. The data was analyzed using GeneSpring GX Version 11.5 software from Agilent. Normalization of the data was done in GeneSpring GX using the 75th percentile shift. Significant up and down regulated genes showing one fold and above within the group of samples were identified. Genes were classified based on functional category and pathways using Biointerpreter Tool -Biological Analysis Software.

Project description:The regulation of phospholipid biosynthesis in Saccharomyces cerevisiae through cis-acting upstream activating sequence inositol (UASino) and trans-acting elements, such as the INO2-INO4 complex and OPI1 by inositol supplementation in growth is thoroughly studied. In this study, we provide evidence for the regulation of lipid biosynthesis by phosphatidylinositol-specific phospholipase C (PLC) through UASino and two trans-acting elements. Gene expression analysis and radiolabelling experiments demonstrated that the overexpression of rice PLC in yeast cells altered phospholipid biosynthesis at the levels of transcriptional and enzyme activity. There are two biological replicates two hour and five hour induction with galactose. The genome wide expression of Saccharomyces cerevisiae strain BY4741 harbouring rPLC-pYES2 and a vectro control (pYES2) were compare with each other.

Project description:B16F10, a murine melanoma cel line is cytolytic to JEV infection. We have identified a B16F10 cell line variant which is non-cytolytic to JEV infection. This variant cell line has two types of cells, one which is persistently infected JEV and another which is resistant to JEV infection. The JEV-resistant cells (B16F10r) were seperated from the presistently infected cells by single cell cloning. To understand the mechanism of JEV resistance microarray analysis was caried out to Identify and characterize genes differentially expressed during in uninfected/JEV-infected B16F10 and B16F10r cells.

Project description:Investigation of the transcription profile of cells transformed by Cr6+ in vivo was undertaken. The objective was to elucidate genomic changes underlying the mechanism of action of the carcinogenic dose of Cr6+and their prevention using metabolic antioxidant Lipoic acid (LA). Cr6+ was administered intraperitoneally to LPS+TPA challenged Swiss albino mice in host mediated cell transformation assay using peritoneal macrophages in vivo. The cell transforming potential of Cr6+ test doses was validated by gain of anchorage independent growth potential in soft agar and loss of Fc receptor on target cells. LA was administered in equimolar doses. Compared to non-transformed cells, the gene expression profile of transformed cells was found to be dysregulated substantially and in dose dependent manner. Genes showing down regulation were found to be involved in tumour suppression; apoptosis, DNA repair, and cell-cycle. A similar response was noted in the genes pertaining to immune system, morphogenesis, cell-communication, energy-metabolism, and biosynthesis. The co-administration of lipoic acid prevented the transcription dysregulation and cell transformation by Cr6+ in vivo. The influenced pathways seem to be crucial for progression as well as mitigation of Cr toxicity; and their response to LA indicated their critical role in mechanism of anti-carcinogenic action of LA. Results are of importance to mitigate Cr6+ induced occupational cancer hazard.
