Description
The samples include RNA from scalp biopsies before treatment and at 8 weeks of treatment with Tofacitinib Citrate 5 mg BID in patients with Alopecia Areata. 32% had a SALT score of 50% or higher and 47% had clinically significant response. Overall design: Open label trial of patients with Alopecia Areata of more than 6 months in duration refractory to standard therapy. Each patient took tofacitinib citrate 5mg BID for 3 months and then stopped. Biopsies were taken pretreatment and then at 8 weeks from the scalp and submitted for RNA sequencing.
Publication Title

Description
Arterial occlusive diseases are major causes of morbidity and mortality. Blood flow to the affected tissue must be restored quickly if viability and function are to be preserved. Collaterals are artery-to-artery or arteriole-to-arteriole interconnections that can bypass an occlusion by providing an alternative route for blood flow to the affected tissue. The increased flow and sheer stress initiate processes that result in the remodeling (arteriogenesis) of these vessels into efficient conductance arteries. Here we report that the mixed-lineage kinase (MLK) pathway activates cJun NH2-terminal kinase (JNK) in endothelial cells. Disruption of Mlk2/3 or Jnk1/2 genes caused severe blockade of blood flow and failure to recover in the femoral artery ligation model of hindlimb ischemia because of abnormal collateral arteries. We show that the MLK-JNK pathway is essential for patterning and maturation of collateral arteries during development, but this pathway is not required for angiogenesis or arteriogenesis in adults. JNK in endothelial cells promotes Delta-like 4-induced Notch signaling and suppresses excessive sprouting angiogenesis during development. This function of the MLK-JNK pathway contributes to normal formation of native collateral arteries. The MLK-JNK pathway is therefore a key regulatory mechanism for vascular development. These data highlight the crucial importance of the collateral circulation in the response to arterial occlusive diseases. Overall design: RNA-seq analysis of mouse lung endothelial cells (MLEC) of the following genotypes Cdh5-Cre+ Jnk1+/+ Jnk2+/+ Jnk3-/-(ECtrl), Cdh5-Cre- Jnk1LoxP/LoxP Jnk2LoxP/LoxP Jnk3-/- (EfCtrl), and Cdh5-Cre+ Jnk1LoxP/LoxP Jnk2LoxP/LoxP Jnk3-/- (E3KO). Three separate samples from mouse lung endothelial cells of each genotype were analyzed.

Affymetrix Zebrafish Genome Array (zebrafish)
Description
Investigating neuronal and photoreceptor regeneration in the retina of zebrafish has begun to yield insights into both the cellular and molecular means by which this lower vertebrate is able to repair its central nervous system. However, knowledge about the signaling molecules in the local microenvironment of a retinal injury and the transcriptional events they activate during neuronal death and regeneration is still lacking. To identify genes involved in photoreceptor regeneration, we combined light-induced photoreceptor lesions, laser-capture microdissection (LCM) of the outer nuclear layer (ONL) and analysis of gene expression to characterize transcriptional changes for cells in the ONL as photoreceptors die and are regenerated. Using this approach, we were able to characterize aspects of the molecular signature of injured and dying photoreceptors, cone photoreceptor progenitors and microglia within the ONL. We validated changes in gene expression and characterized the cellular expression for three novel, extracellular signaling molecules that we hypothesize are involved in regulating regenerative events in the retina.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Inadequate protein intake initiates an accommodative response with adverse changes in skeletal muscle function and structure. mRNA level changes due to short-term inadequate dietary protein might be an early indicator of accommodation. The aims of this study were to assess the effects of dietary protein and the diet-by-age interaction on the skeletal muscle transcript profile. Self-organizing maps were used to determine expression patterns across protein trials.
Publication Title
The skeletal muscle transcript profile reflects accommodative responses to inadequate protein intake in younger and older males.

Description
JNK3 deficiency leads to upregulation of growth factors such as Vegfa, Pdgfb, Pgf, Hbegf and Tgfb3 in ischemic muscle. In order to ascertain the molecular mechanisms responsible for the accelerated blood flow recovery in Mapk10-deficient mice, a micro-array analysis of gastrocnemius muscle from these mice was performed after HLI. We observed a significant up-regulation of several growth factors known to improve blood flow recovery in the Mapk10-/- muscle compared to WT
