Description
ETS1 and RAS/ERK regulate a common gene expression program in establishing enviroment suitable for prostate cancer cell migration. Overall design: mRNA profiles of luciferase knockdown (WT), ETS1 knockdown, and U0126 treated DU145 cells were generated using deep sequencing, in triplicate, using Illumina HiSeq. Knockdowns were stable shRNA expression from a lentiviral construct selected with puromycin.

Description
Knockdowns of c-JUN and JUND had opposite effects on PC3 prostate cell migration. We predicted that c-JUN and JUND control the same set of cell migration genes, but in opposite directions. To test this hypothesis, mRNA with expression changes in c-JUN and JUND knockdown PC3 cell lines were compared to mRNA levels in control (luciferase knockdown) PC3 cells by RNA-seq. Overall design: mRNA profiles of luciferase knockdown (WT), c-Jun knockdown, and Jun-D knockdown in PC3 cells were generated using deep sequencing, in triplicate, using Illumina HiSeq. Knockdowns were stable shRNA expression from a lentiviral construct selected with puromycin.

Description
In response to viral pathogens, the host upregulates antiviral genes that suppress translation of viral mRNAs. However, induction of such antiviral responses may not be exclusive to viruses as the pathways lie at the intersection of broad inflammatory networks that can also be induced by bacterial pathogens. Using a model of Gram-negative sepsis, we show that propagation of kidney damage initiated by a bacterial origin ultimately involves antiviral responses that result in host translation shutdown. We determined that activation of the Eif2ak2-Eif2a axis is the key mediator of translation initiation block in late phase sepsis. Reversal of this axis mitigated kidney injury. Furthermore, temporal profiling of the kidney translatome revealed that multiple genes involved in formation of the initiation complex were translationally altered during bacterial sepsis. Collectively, our findings implicate that translation shutdown is indifferent to the specific initiating pathogen and is an important determinant of tissue injury in sepsis. Overall design: Bulk 20 um thickness specimens from cross-sectional human kidney biopsies embedded in OCT underwent RNA sequencing. All subjects had ATN, AIN, or a mix of both conditions.

Description
Preconditioning with a small dose of endotoxin confers unparalleled protection against otherwise lethal models of sepsis. The mechanisms of preconditioning have been investigated extensively in isolated immune cells such as macrophages. However, the role of tissue in mediating the protective response to preconditioning remains unknown. Using the kidney as a model organ, we identify the essential role of the renal epithelial cell in mediating the full expression of protective preconditioning. The protective phenotype is characterized by the clustering of macrophages around S1 segments of proximal tubules, which forms a functional unit mediating protection. To investigate the molecular pathways, we laser microdissected S1 segments from the following: 1) Non-preconditioned mice subjected to single-dose 5 mg/kg lipopolysaccharide (0111:B4, LPS) intraperitoneally for 24 hours. 2) Preconditioned mice subjected to 0.25 mg/kg LPS followed 24 hour later by 5 mg/kg LPS (LPS/LPS). 3) Control mice (saline vehicle).

Description
Glucocorticoids (GC) have a major impact on the biology of normal and malignant cells of the lymphoid lineage. This includes induction of apoptosis which is exploited in the therapy of acute lymphoblastic leukemia (ALL) and related lymphoid malignancies. MicroRNAs (miRNAs) and the related mirtrons are ~22 nucleotide RNA molecules implicated in the control of essential biological functions including proliferation, differentiation and apoptosis. They derive from polymerase-II transcripts but whether GCs regulate miRNA-encoding transcription units is not known. We investigated miRNA/mirtron expression and GC regulation in 8 ALL in vitro models and 13 ALL children undergoing systemic GC monotherapy using a combination of expression profiling techniques, real time RT-PCR and northern blotting to detect mature miRNAs and/or their precursors. We identified a number of GC-regulated miRNAs/mirtrons, including the myeloid-specific miR-223 and the apoptosis and cell cycle arrest-inducing mir15~16 cluster. Thus, the observed complex changes in miRNA/mirtron expression during GC treatment might contribute to the anti-leukemic GC effects in a cell context dependent manner.

MicroRNA regulates protein expression of cells by repressing translation of specific target messenger transcripts. Loss of the neuron specific microRNA miR-128 in Dopamine D1-receptor expressing neurons in the murine striatum (D1-MSNs) lead to increased neuronal excitability, locomotor hyperactivity and fatal epilepsy.

Description
We demonstrate that PKA signalling drives zonal conversion within adult adrenocortical lineage in a sexually dimorphic manner. Our data establish that Prkar1a genetic ablation (leading to constitutive PKA activation) in the adult adrenocortical lineage leads to endocrine hyperactivity and accelerates adrenal cortex renewal. This results in increased zona fasciculata differentiation and final conversion into reticularis-like zone. This phenomenon relies partly on sex-dependent mechanisms of cortical renewal, on which the male androgenic milieu exerts a repressive action through induction of WNT signalling, which in turn antagonizes PKA signalling and cortical cell turnover.
