Description
The aim of this work was to identify functional features that are specific of human Treg cells, through the identification of genes that are differentially expressed: 1/ in activated Treg clones versus activated Thelper clones; 2/ in Th clones activated in the presence versus the absence of TGFb; 3/ in suppressed Th clones, i.e. Th clones activated in the presence of Treg clones, versus controls.
Publication Title
Comparison of stable human Treg and Th clones by transcriptional profiling.

- Affymetrix Human Gene 2.1 ST Array (hugene21st)
Description
sorafenib is the treatment of reference for hepatocellular carcinoma (HCC). We applied sorafenib on the human HCC cell line Huh7 and the subclone shRb, carrying a stable knock-down of the expression of the RB1 gene, a key regulator of liver carcinogenesis. Our aim was to better understand the physiologic and metabolic consequences of the exposure of HCC cells to sorafenib.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Melanoma growth is driven by malignant melanoma initiating cells (MMIC) identified by expression of the ATP-binding cassette (ABC) member, ABCB5. ABCB5+ melanoma subpopulations have been shown to overexpress the vasculogenic differentiation markers CD144 (VE-cadherin) and TIE-1 and are associated with CD31-negative vasculogenic mimicry (VM), an established biomarker associated with increased patient mortality. Here we identify a critical role for VEGFR-1 signaling in ABCB5+ MMIC-dependent VM and tumor growth. Global gene expression analyses, validated by mRNA and protein determinations, revealed preferential expression of VEGFR-1 on ABCB5+ tumor cells purified from clinical melanomas and established melanoma lines. In vitro, VEGF induced in a VEGFR-1-dependent manner expression of CD144 in ABCB5+ subpopulations that constitutively expressed VEGFR-1, but not in ABCB5- bulk populations that were predominantly VEGFR-1-negative. In vivo, melanomaspecific shRNA-mediated knockdown of VEGFR-1 blocked the development of ABCB5+ VM morphology and inhibited ABCB5+ VM-associated production of the secreted melanoma mitogen, laminin. Moreover, melanoma-specific VEGFR-1 knockdown markedly inhibited tumor growth (by >90%). Our results demonstrate that VEGFR-1 function in MMIC regulates VM and associated laminin production, and show that this function represents one mechanism through which MMIC promote tumor growth.

VEGFR-1 expressed by malignant melanoma-initiating cells is required for tumor growth.

- Affymetrix Mouse Gene 2.1 ST Array (mogene21st)
Description
S. epidermidis ability to form biofilms on indwelling medical devices and its association with the emergence of chronic infections is its main virulence factor. Nevertheless, it has been shown that the cells released from these biofilms are associated with the advent of serious acute infections with bacteraemia as one of the major clinical manifestations. Despite their clinical relevance, very little is known about the impact of biofilm-released cells in pathogenesis. Hence, herein, we characterized the murine immune response to the presence of cells released from S. epidermidis biofilms analysing spleen cells transcriptome by microarrays. These findings may help to explain the recurrent inflammatory symptoms presented by patients with colonization of indwelling medical devices.

Description
Endocardial (EE) and Aortic (AE) endothelial cells were isolated from the same two rats, pooled (EE and AE kept separately) and cultured for 2 passages. Culture conditions and confluence of EE and AE cell cultures were kept as identical as possible. RNA was isolated and the expression profile of both endothelial cell types was compared using the Affymetrix rat genome U34A array.
