This study analyzes transcriptome profiles in pre-germinated seeds and hypoxia-treated seedlings of Arabidopsis thaliana wild type (Col-0) and homozygous mutants (prt6-1 and ate1 ate2). This dataset includes CEL files, RMA signal values and MAS5 P/M/A calls. For pre-germinated seeds, seeds imbibed for 24 h were used for total RNA extraction. For hypoxia treatment, 7-d-old seedlings were incubated in a hypoxia chamber for 2 h and the entire seedling was subjected to RNA extraction. Quantitative profiling of cellular mRNAs was accomplished with the Affymetrix ATH1 platform. Changes in the transcriptome during early seed germination stage and in response to hypoxia in seedlings were evaluated. The data led to identification of mRNAs with abundance regulated by PRT6 and ATE1 / ATE2, which are essential components for the N-end rule pathway of targeted proteolysis (NERP). A combination of genetic, biochemical and molecular analyses reveal that NERP coordinates the stability of key ethylene responsive factor (ERF) family transcription factors, which regulate expression of core hypoxia response genes and tolerance to low oxygen stress. This indicates that the NERP functions as a homeostatic sensor of low oxygen in plants.
Homeostatic response to hypoxia is regulated by the N-end rule pathway in plants.

View SamplesThe polyadenosine RNA binding proteins (Pabs) represent one class of RNA binding proteins that play critical roles in gene expression. This class includes the well-studied nuclear and cytoplasmic Pabs, PABPN1 and PABPC1, respectively, as well as the newly characterized nuclear Pab, zinc finger CCCH-type containing #14, or ZC3H14. ZC3H14 was recently linked to a form of intellectual disability, suggesting a critical role for ZC3H14 in neurons; however, the post-transcriptional function of ZC3H14 is unknown. In this study, we performed a microarray analysis of cells depleted of ZC3H14 or PABPN1 in MCF-7 breast cancer cells. These results revealed that PABPN1 significantly affected ~17% of expressed transcripts as compared to ZC3H14, which affected ~1% of expressed transcripts, suggesting that ZC3H14 has specific mRNA targets. The differentially expressed mRNAs identified in this analysis not only provide information about the classes and types of transcripts that are regulated by these proteins, but also represent a set of transcripts that could be directly bound by ZC3H14 and/or PABPN1.

Epigenetic regulator Smchd1 functions as a tumor suppressor.
Specimen part
View SamplesSmchd1 appears to act as a tumour suppressor in the transformed fibroblast model. We find gene expression differences are most pronounced in the transformed MEFs. We always detect a small number of clustered genes and imprinted genes as differentially expressed, along with others involved in tumorigenesis.

We find gene expression differences are most pronounced in the premalignant cells, and observe more variability in end stage lymphomas. We always detect a small number of clustered genes and imprinted genes as differentially expressed, along with others involved in tumorigenesis.

View SamplesOur study demonstrated that e-cigarettes, both with and without nicotine, induced sex-dependent gene expression change. This RNA-seq study examined the expression profiles of brain frontal cortex samples from mice exposed to classic tobacco flavored bluâ„¢ e-cigarettes during gestation and lactation. Overall design: Brains were extracted and sectioned from ~1-month-old male and female offspring the week following exposure, RNA was isolated and purified from frontal cotrex tissues, and gene expression profiles were analyzed by RNA Sequencing.
