View Sampleslinc00598 is a nuclear localized long noncoding RNA which transcribed in downstream of FoxO1. Previous studies showed that several nuclear retained lncRNAs function as transcriptional regulators. To find out the function of linc00598 as a transcriptional regulator, we performed microarray analysis using linc00598 knock down stable HEK293t cells. The results showed that positive cell cycle regulation related genes including cyclin D2 were regulated transcriptionally by linc00598. It was also observed that knock down of linc00598 induces G0/G1 cell cycle arrest and inhibit proliferation. Therefore linc00598 represents a novel cell cycle regulatory lncRNA and may be involved in promoting transformation of human cells.
Long noncoding RNA linc00598 regulates CCND2 transcription and modulates the G1 checkpoint.

View SamplesIron is an essential element for almost all organisms, catalyzing numerous essential redox reactions by virtue of its unique electrochemical properties. Iron levels in cells need to be carefully balanced. Rglg1/2 is an Arabidopsis mutant which display a pleiotropic phenotype partly resembling iron-deficient plants.To dissect global transcriptional regulation of gene expression in iron-deficient plants, we conducted genome-wide proteomic and transcriptomic surveys of leaves and roots from iron-sufficient and iron-deficient Col-0 wild-type plants and rglg1 rglg2 double mutants.

View SamplesWe applied a meta-analysis of datasets from seven different microarray studies on lung cancer for differentially expressed genes related to survival time (under 2 y and over 5 y). Systematic bias adjustment in the datasets was performed by distance-weighted discrimination (DWD). We identified a gene expression signature consisting of 64 genes that is highly predictive of which stage I lung cancer patients may benefit from more aggressive therapy.

View SamplesPrevious research has shown that glutamine and sucrose treatment of excised poplar stems induces bark storage protein (BSP) gene expression. The objective of this research is to identify changes in gene expression associated with metabolic regulation of nitrogen storage and cycling and use this information to identify potential regulatory genes. Significant, differentially expressed genes were identified in excised poplar stems incubated in solutions of glutamine, sucrose, glycine, glutamine+glucose, and glutamine+sucrose compared to incubation in a water control.

View SamplesTCE is a non-genotoxic hepatocarcinogen in mouse, but not in rat or human. Extrapolation of data from laboratory animals to humans is difficult due to species-specific differences. To identify molecular pathways and biological changes responsible for species-specific differences in hepatocarcinogenesis, we analyzed gene expression profiles of livers from B6C3F1 mice and SD rats administered TCE by oral gavage once or repeatedly every 24 hrs for 14 days. Gene expression analysis revealed distinct clusters of transcriptional profiles in single- and repeated-dose mice and rats. Pathway analysis showed differences in biological pathways between single- and repeated-dose mice and rats. Activation of the MAPK signaling cascade and ubiquitin-proteasome inhibitory function, as well as inhibition of TGF-beta signaling, were specific to mice and suggest a role in hepatocyte proliferation. Although pathological analysis showed no evidence of apoptosis, gene expression analysis revealed changes in apoptosis-related genes. In addition to the previously reported suppression of apoptosis, results in repeated-dose mice showed that toxicity induced by TCE in turn induces apoptosis.
