Project description:By comparing the gene expression profiling in Anoxybacillus sp. SK 3-4 with and without aluminum exposure, the sets of gene up-regulated and down-regulated by aluminum were identified. The function of genes or proteins induced under these conditions can a reflection of the mechanism of resistance. Transcriptome profiling of Anoxybacillus sp. SK 3-4 treated by aluminum would allow a better understanding of the gene involving in tolerance and removal of aluminum.

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of transfected NC K1 cells and transfected si-NEAT1_2 K1 cells. The goals of this study are to analysis the different mRNA expression between transfected NC K1 cells and transfected si-NEAT1_2 K1 cells. Quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis. We performed mRNA-seq in the NEAT1_2 knockdown group and NC group in the K1 cell line. We found that after knockdown of NEAT1_2, 615 mRNAs were upregulated and 2364 mRNAs were downregulated.
Project description:To identify the developmentally regulated genes, which could confound identification of PN and CQ drug responsive genes, RNA samples from drug-free synchronized cultures from ring, trophozoite, and schizont stages were individually labelled and hybridized with a pooled sample from the three stages. The data from this experiment were used to compare the developmental profile of the K1 strain with the data from other P. falciparum strains.
Project description:Pyronaridine (PN) and chloroquine (CQ) are structurally related anti-malarial drugs with primarily the same mode of action. However, PN is effective against several multidrug-resistant lines of Plasmodium falciparum, including CQ-resistant lines, suggestive of important operational differences between the two drugs. Synchronized trophozoite-stage cultures of P. falciparum strain K1 (CQ resistant) were exposed to 50% inhibitory concentrations (IC50) of PN and CQ, and parasites were harvested from culture after 4 and 24 hours exposure. Global transcriptional changes effected by drug treatment were investigated using DNA microarrays.
