Affymetrix Rat Gene 1.0 ST Array (ragene10st)
Description
Myocardial infarction (MI) often results in left ventricular (LV) remodeling followed by heart failure (HF). It is of great clinical importance to understand the molecular mechanisms that trigger transition from compensated LV injury to HF and to identify relevant diagnostic biomarkers. In this study, we performed transcriptional profiling of LVs in rats with a wide range of experimentally induced infarct sizes and of peripheral blood mononuclear cells (PBMCs) in animals that developed HF.

Description
Despite a substantial progress in diagnosis and therapy, acute myocardial infarction (MI) is a major cause of mortality in the general population. A novel insight into the pathophysiology of myocardial infarction obtained by studying gene expression should help to discover novel biomarkers of MI and to suggest novel strategies of therapy. The aim of our study was to establish gene expression patterns in leukocytes from acute myocardial infarction patients.

Illumina HiSeq 2500
Description
We report age-related gene expression of Treg cells isolated from injured muscle and spleen. Male C57BL/6 Foxp3-GFP reporter mice were injured intramuscularly with cardiotoxin. Tregs were sorted directly into Trizol from injured muscle and spleen 4 days post-injury. Overall design: Gene expression profiling of muscle and splenic Tregs from 2- vs >6-month old mice (biological duplicate for each).

Description
We report gene expression of Treg cells isolated from injured muscle in IL-33 vs PBS treated mice. Male Foxp3-GFP C57BL/6 reporter (2 months old) mice were injured intramuscularly with cardiotoxin/rIL-33 (0.3 ug/muscle). Tregs were sorted directly into Trizol from injured muscle 4 days post-injury. Overall design: Gene expression profiling of muscle Tregs from IL-33 vs PBS injured mice.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
A phenotypically and functionally distinct population of CD4+ Foxp3+ T cells (Tregs) rapidly accumulates in acutely injured skeletal muscle of mice, just as invading myeloid-lineage cells switch from a pro-inflammatory to a pro-regenerative state. Analysis of gene expression of Tregs and CD4+Foxp3- T cells (Tconvs) from injured muscle and spleen revealed that the transcriptome of muscle Treg cells is distinct from that of splenic Tregs. A set of genes is uniquely expressed by muscle Tregs, while another set is over-expressed by the two muscle populations vis--vis their two spleen counterparts.

Description
A comparative analysis of gene expression of injured skeletal muscle from wild-type (Foxp3-DTR-) and Treg-depleted (Foxp3-DTR+) mice showed that Treg cells are critical for effective repair and regeneration of acute injury of skeletal muscle.

Description
Global gene expression analysis of injured skeletal muscle showed that amphiregulin (Areg), a growth factor over-expressed by muscle Treg cells, enhances muscle regeneration both in the presence and in the absence of Tregs.

Description
CD4+Foxp3+ regulatory T cells (Tregs) accumulate in skeletal muscle from dystrophin-deficient mdx mice. Analysis of global gene expression in muscles from mdx mice treated with anti-CD25 compared with muscles from mdx mice treated with control antibody revealed that Tregs partially protect mdx mice from muscle pathology and promote muscle repair/regeneration.
