Description
Using mRNA-seq, we determined intron retaining genes that were differentially regulated in FACS purified cells at three progressive stages of mouse granulopoiesis; CD34+Kit+Gr-1low promyelocytes, CD34-Kit-Gr-1mid myelocytes and CD34-Kit-Gr-1high granulocytes. We found that IR affects 86 genes, including those specific to granulocyte (Lyz2 and MMP8) and nuclear architecture (Lmnb1 and Lbr). IR was associated with the decrease in protein levels measured by mass spectrometry (P=0.0015, binomial test). Inhibition of NMD in granulocytes resulted in marked accumulation of 39/86 intron retaining mRNAs (P<0.05, RUV procedure with Holm-Bonferroni correction), indicating that IR triggers NMD to downregulate mRNA and protein expression.

Description
Normal human bronchial epithelial cells were studied under four different conditions: control, pressure 30 cmH2O, AG1478 (1 microM), and pressure plus AG1478 at 1, 3, and 8 hours, all in the absence of exogenous EGF.

- Affymetrix Pseudomonas aeruginosa Array (paeg1a)
Description
Wound infections are traditionally thought to occur when microbial burden exceeds the innate clearance capacity of host immune system. Here we introduce the idea that the wound environment itself plays a significant contributory role to wound infection.
Publication Title
Pseudomonas aeruginosa wound infection involves activation of its iron acquisition system in response to fascial contact.

- Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Multiple myeloma is largely incurable, despite development of therapies that target myeloma cell-intrinsic pathways. Disease relapse is thought to originate from dormant myeloma cells, localized in specialized niches, which resist therapy and re-populate the tumor. However, little is known about the niche, and how it exerts cell-extrinsic control over myeloma cell dormancy and re-activation. In this study we track individual myeloma cells by intravital imaging as they colonize the endosteal niche, enter a dormant state and subsequently become activated to form colonies. We demonstrate that dormancy is a reversible state which is switched on by engagement with bone lining cells or osteoblasts, and switched off by osteoclasts remodeling the endosteal niche. Dormant myeloma cells are resistant to chemotherapy targeting dividing cells. The demonstration that the endosteal niche is pivotal in controlling myeloma cell dormancy highlights the potential for targeting cell-extrinsic mechanisms to overcome cell-intrinsic drug resistance and prevent disease relapse.

Osteoclasts control reactivation of dormant myeloma cells by remodelling the endosteal niche.

Description
Type II Enteropathy-associated T-cell lymphoma (Type II EATL) is an aggressive intestinal T-cell lymphoma with poor prognosis and has not been molecularly profiled. Through targeted amplicon sequencing, we identified a large portion of Type II EATL samples that harbor mutations in the STAT5B, JAK3 and GNAI2 genes. Here we performed gene expression profiling on four Type II EATL samples in order to better characterize this disease. As Type II EATL is suggested to arise from CD8+ IELs, we integrated our data with publicly available profile of CD8 and CD8 T-cells from healthy donors (GSE33374). Gene expression profiling independently demonstrated strong enrichment of several aspects of GPCR and JAK-STAT signaling pathways. Moreover, an significant association was identified with genes containing STAT5B binding sites in their promoters.

Description
We used phytochemical profiling techniques to generate a list of compounds present in each of 13 Equisetum arvense samples sourced globally. We used microarrays to detail the global programme of gene expression underlying the treatment of the model system Saccharomyces cerevisiae to a chosen number of these extracts. A thorough bioinformatic analysis was performed to identify the relationship between phytochemical and gene expression response profiles.
