The dual leucine zipper kinase (DLK) is a mitogen-activated kinase kinase kinase that can activate the downstream cJun N terminal kinase (JNK) pathway (ref). We have previously reported that DLK is a positive regulator of the retrograde injury signaling and axon regeneration that unfolds after sciatic nerve injury (ref). Since DLK is required for activities of injury-associated transcription factors such as cJun and STAT3, we hypothesized that DLK is also necessary for the transcriptional responses to peripheral nerve injury. In the current study, we identify DLK-dependent transcriptome in dorsal root ganglion (DRG) neurons using a sciatic nerve injury paradigm. The DEG analysis reveals that DLK regulates regeneration/injury-associated genes in both basal and injured conditions. By performing gene ontology analysis, we suggest functional annotations and the involved genes as regulatory components of the axonal regeneration program. Finally, our comparative analysis indicates that DLK is required for a specific retrograde signaling pathway that regulates a regeneration program shared between PNS and CNS models.

View SamplesGlobal restriction of protein synthesis is a hallmark of cellular stress. Using hydrogen peroxide, we monitor the transcript level and also the translation status for each RNA using cycloheximide to freeze elongating ribosomes. Polyribosome fractionation of cell extracts was used to separate highly translated and poorly translated mRNAs that were then separately analysed.
Global translational responses to oxidative stress impact upon multiple levels of protein synthesis.

View SamplesOne common form of translational control is mediated by proteins that bind to the mRNA 5' cap-binding protein eIF4E. These proteins are collectively called 4E binding proteins (4EBPs). Saccharomyces cerevisiae possesses two 4EBPs that are encoded by non-essential genes called CAF20 and EAP1. To determine the impact of gene deletion on gene expression, we monitored the transcript level and also the translation status for each RNA using cycloheximide to freeze elongating ribosomes in wild-type, caf20 and eap1 cells. Polyribosome fractionation of cell extracts was used to separate highly translated and poorly translated mRNAs that were then separately analyzed.
Identifying eIF4E-binding protein translationally-controlled transcripts reveals links to mRNAs bound by specific PUF proteins.

View Sampleswe construct a comprehensive mouse transcriptomic BodyMap across 17 tissues of six-weeks old C57BL/6JJcl mice using RNA-seq. We find different expression patterns between protein-coding and non-coding genes. Liver and adrenal gland expressed the least complex transcriptome, whereas testis and ovary harbor more complex transcriptome than other tissues. We report a comprehensive list of tissue-specific genes across 17 tissues. Our study provides a unique resource of mouse gene-expression profiles, which is helpful for further biomedical research.

View SamplesTo obtain a comprehensive understanding of transcriptomic reprogramming under salt stress, we performed whole genome RNA sequencing on salt-treatment soybean seedlings, on two tissues in a time-course experiment (0h, 1h, 2h, 4 h, 24h and 48h). This time series dataset enables us to identify important hubs and connection of gene expressions. We highlighted the analysis of phytohormone signaling pathways and their possible cross-talking. Gene expression regulation also controls adjustment of carbon and nitrogen metabolism. In general, the treated seedlings had turned off the photosynthetic mechanism and enhanced sugar catabolism to provide energy for survival. Primary nitrogen assimilation was shut down while re-distribution of nitrogen resources was activated. Genes for other protective mechanisms were also induced, including structural modification, ion-sequestering, and scavenging of reactive oxygen species.

View SamplesCalcium 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.
