Background :To evaluate the impact of the duration of chronic inflammation on gene expression in skeletal muscle biopsies (MBx) from untreated children with juvenile dermatomyositis (JDM) and identify genes and biological processes associated with the disease progression, expression profiling data from 16 girls with active symptoms of JDM greater or equal to 2 months were compared with 3 girls with active symptoms less than 2 months.
Duration of chronic inflammation alters gene expression in muscle from untreated girls with juvenile dermatomyositis.

View SamplesLasting B-cell persistence depends on survival signals that are transduced by cell surface receptors. Here, we describe a novel biological mechanism essential for survival and homeostasis of normal peripheral mature B cells and chronic lymphocytic leukemia (CLL) cells, regulated by the heparin-binding cytokine, midkine (MK), and its proteoglycan receptor, the receptor-type tyrosine phosphatase zeta (RPTP). We demonstrate that MK initiates a signaling cascade leading to B cell survival, by binding to RPTP. In mice lacking PTPRZ, the proportion and number of the mature B cell population is reduced. Our results emphasize a unique and critical function for MK signaling in the previously described MIF/CD74 induced survival pathway. Stimulation of CD74 with MIF leads to c-Met activation, resulting in elevation of MK expression in both normal mouse splenic B and CLL cells. Our results indicate that MK and RPTP are important regulators of the B cell repertoire. These findings could pave the way towards understanding the mechanisms shaping B cell survival, and suggest novel therapeutic strategies based on the blockade of the midkine/RPTP-dependent survival pathway.
The cytokine midkine and its receptor RPTPζ regulate B cell survival in a pathway induced by CD74.

View SamplesHdac3 is an important target of HDAC inhibitors used in the treatment of cutaneous T cell lymphoma. In order to gain an understanding of Hdac3 function in T cells,we deleted Hdac3 from early mouse thymocytes using LCK-Cre. Hdac3 deletion resulted in a loss of single positive thymocytes due to a defect in positive selection at the double positive (DP) stage of thymocyte development. To better characterize this defect, we sorted the DP1 and DP2 populations to for gene expression profiling. Overall design: Total RNA was extracted from DP1 (GFP+CD4+CD8+CD5loTCRblo) or DP2 (GFP+CD4+CD8+CD5hiTCRbint) thymocytes isolated by FACS from Hdac3+/+ or Hdac3F/F LCK-Cre+ animals. Libraries were constructed from rRNA-depleted total RNA pools to identify altered gene expression in DP populations following Hdac3 deletion.

View SamplesThe objective of the study was to compare the wound macs with corresponding macs derived from peripheral blood monocytes (MDMs). Wound site macrophage (wound macs were isolated from human subjects with chronic wounds. Matching blood monocyte derived macrophages (MDM) were obtained from same subjects. Transcriptome profiling (GeneChip, Affymetrix) was performed.The expression values of genes were normalized using global scaling approach.
