Affymetrix Rat Gene 2.1 ST Array (ragene21st)
Description
Accute stretch and tachycardia are capable of inducing pathological excitation transcription coupling - an early invent before structural cardiac remodeling which transitions to heart failure. The sodium calcium exchanger is a key player in maintaining calcium homeostasis and is implicated in pathological signaling during heart failure.
Publication Title
The role of stretch, tachycardia and sodium-calcium exchanger in induction of early cardiac remodelling.

Description
The rate of transcription elongation plays important roles in the timing of expression of full-length transcripts as well as for the regulation of alternative splicing. In this study we coupled Bru-Seq technology with 5,6-dichlorobenzimidazole 1-ß-D-ribofuranoside (DRB) to estimate the elongation rates of over 2,000 individual genes in human cells. This technique, BruDRB-Seq, revealed gene-specific differences in elongation rates with a median rate of around 1.5 kb/min. We found that genes with fast elongation rates showed higher densities of H3K79m2 and H4K20me1 marks compared to slower elongating genes. Furthermore, fast elongation rates had a positive correlation with gene length, low complexity DNA sequence and distance from nearest active transcription unit. Features that negatively correlated with elongation rate included exon density and the number of LINE sequences in the gene. The BruDRB-Seq technique offers new opportunities to interrogate mechanisms of regulation of transcription elongation. Overall design: Measurement of RNA Pol II elogation rate. Normal fibroblasts (HF1 and TM), Cockayne syndrome group B fibroblasts, K562 and MCF-7 cells were exposed to DRB for 60 minutes, after which a washout was performed. Nascent RNA was labeled using bromouridine for 10 minutes immediately after the washout. The genomic region extending from actice Trancription Start Sites was used to determine the gene''s elongation rate. Please note that the nf_0h_3* samples are duplicated sample records of GSM1062445 and GSM1062446, for the convenient retrieval of the complete raw data from SRA.

Description
Fibroblast growth factor-23 (FGF23), a circulating protein produced in bone, causes renal inorganic phosphate (Pi) wasting by down-regulation of sodium phosphate co-transporter 2a (Npt2a). The mechanism behind this action is unknown. We have previously generated transgenic mice (TG) expressing human wild-type FGF23 under the control of the 1 (I) collagen promoter. In this study we performed a large scale gene expression study of kidneys from TG mice and wild-type littermates. Several genes that play a role in Pi regulation had decreased expression levels, such as Npt2a, but also Pdzk1 which is a scaffolding protein known to interact with NPT2a. Importantly, the Klotho gene, a suggested crucial co-factor for FGF23 receptor binding and activation, was the most affected decreased gene. However, other genes proposed to regulate Pi levels, such as secreted Frizzled Related Protein 4 (sFRP4), Na+/H+ exchanger regulatory factor 1 (NHERF1) and the FGF-receptors 1-4, revealed no changes. Interestingly, expression levels of inflammatory response genes were increased and histological analysis revealed tubular nephropathy in the TG mice kidneys. In conclusion, FGF23 TG mice have altered kidney gene expression levels of several genes thought to be part of Pi homeostasis and an increase in inflammatory response genes, data supported by histological analysis. These findings may lead to further understanding of how FGF23 mediates its actions on renal Pi regulation.
