Calcium acts as a universal second messenger to regulate gene expression in both developmental processes and responses to environmental stresses. Previous studies showed that a number of stimuli can induce calcium increases in the cytoplasm and nucleus, independently. However, the gene expression network deciphering [Ca2+]cyt and/or [Ca2+]nuc signaling pathway remain obscure.

View SamplesC2C12 cells, as mouse-derived myoblasts, are a classic cell model for studying skeletal muscle development. We knocked down the immunoglobulin superfamily containing leucine-rich repeat (Islr) gene in C2C12 cell line and studied the effect of Islr on the proliferation and differentiation of C2C12 cells.

View SamplesTo delineate the mechanism underlying SRSF1/delta133p53-mediated alterations in vascular smooth muscle cell (VSMC) proliferation, we analyzed the genome-wide gene expression profiles in cultured human aortic smooth muscle cells (HASMCs) with delta133p53-overexpression and Ang II treatment versus GFP controls using RNA-Seq approach.

View SamplesPlant seedlings undergo distinct developmental processes in the dark and in the light. Using an activation-tagging approach, we identified SRS5ox, which overexpresses SHI-RELATED SEQUENCE 5 (SRS5) following induction with estradiol in Arabidopsis thaliana. SRS5 overexpression in SRS5ox seedlings results in a constitutive photomorphogenesis phenotype in the dark. To investigate potential downstream genes of SRS5, the expression levels of genes assayed by RNA-seq in 5-day-old SRS5ox seedlings grown under white light treated with or without estradiol for 2 hours, respectively.

View SamplesTo elucidate the mechanisms by which Nrf2 regulates cell growth, we performed global gene expression profiling of A549 lung cancer cells with knockdown of Nrf2. Gene networks associated with carbohydrate metabolism and drug metabolism were significantly downregulated in Nrf2-depleted A549 cells. Gene Set Enrichment Analysis revealed significant enrichment of genes associated with carbohydrate catabolic processes, positive regulation of metabolic processes, PPP, and arachidonic acid metabolism. In summary, this analysis revealed that Nrf2 positively regulates transcription of genes that play key roles in central carbon metabolism.
Transcription factor NRF2 regulates miR-1 and miR-206 to drive tumorigenesis.

View SamplesWe examine the potential of Kras as a metabolic target in lung cancer using the KrasLSL-G12D lung cancer model. We demonstrate that mutant Kras drives a lipogenic gene expression program, and that fatty acid synthesis is important in Kras-induced tumorigenesis.
De novo lipogenesis represents a therapeutic target in mutant Kras non-small cell lung cancer.

View SamplesUsing microarray, the anther transcript profiles of the three indica rice CMS lines revealed 622 differentially expression genes (DEGs) in each of the three CMS lines. GO and Mapman analysis indicated that these DEGs were mainly involved in lipid metabolic and cell wall organization. Comprised with the gene expression of sporophytic and gametophytic CMS lines, 303 DEGs were differentially expressed and 56 of them were down-regulated in all the CMS lines. Co-expression network analysis suggested that many genes were significantly differentially expressed in the CMS lines. These down-regulated DEGs in the CMS lines were found to be involved in tapetum or cell wall formation and their suppressed expression might be related to male sterility. The present study will give some information for the nuclear gene regulation by different cytoplasmic genotypes and provide some candidate genes for pollen development in rice.
Comparative transcript profiling of alloplasmic male-sterile lines revealed altered gene expression related to pollen development in rice (Oryza sativa L.).
