Illumina HumanRef-8 v3.0 expression beadchip
Description
The goal of this study was to determine what genes are up- and down-regulated in response to lupus immune complexes in purified CD14+ monocyte stimulations. Our results have shown that novel genes are induced by immune complexes but the response is less robust when using purified monocytes versus total PBMCs

Description
These experiments were done to compare the gene expression profiles in CD4+ T cells responding to antigen presented by dendritic cells transiently or persistently. Some treatments include the activation of the dendritic cells by CD40 engagement.
Publication Title
Sustained antigen presentation can promote an immunogenic T cell response, like dendritic cell activation.

IlluminaHiSeq2500
Description
The aim of our study was to discover a miR marker panel prognostic of 5-year survival in OSCC patients that may be utilized in parallel with the current clinical covariates. We assessed differential expression of miRNAs genome-wide via deep sequencing in 20 tumor tissue samples. We also attempted to identify deregulated miR expression signatures that may serve as the prognostic marker of cancer survival. Selected miR marker-based panel then may serve as a guide for selection of appropriate follow-up chemo/radiation treatment, significantly improving the clinical management of OSCC and the overall survival rate. Overall design: Identify miRs differentially expressed in the poor prognosis group compared to the good prognosis group

Description
Hepatocellular carcinoma (HCC) represents a major health problem as it afflicts an increasing number of patients worldwide. Albeit most of the risk factors for HCC are known, this is a deadly syndrome with a life expectancy at the time of diagnosis of less than 1 year. Definition of the molecular principles governing the neoplastic transformation of the liver is an urgent need to facilitate the clinical management of patients, based on innovative methods to detect the disease in its early stages and on more efficient therapies. In the present study we have combined the analysis of a murine model and human samples of HCC to identify genes differentially expressed early in the process of hepatocarcinogenesis, using a microarray based approach. Expression of 190 genes was impaired in murine HCC from which 65 were further validated by low-density array RT PCR. The expression of the best 45 genes was then investigated in human samples resulting in 18 genes which expression was significantly modified in HCC. Among them, JUN, methionine adenosyltransferase 1A and 2A, phosphoglucomutase 1, and acyl CoA dehydrogenase short branched chain indicate defective cell proliferation as well as one carbon pathway, glucose and fatty acid metabolism, both in HCC and cirrhotic liver, a well known preneoplastic condition. These alterations were further confirmed in public transcriptomic datasets from other authors. In addition, vasodilator stimulated phosphoprotein, an actin-associated protein involved in cytoskeleton remodelling, was also found to be increased in the liver and serum of cirrhotic and HCC patients. In addition to revealing the impairment of central metabolic pathways for liver homeostasis, further studies may probe the potential value of the reported genes for the early detection of HCC.

Description
Ovariectomized virgin Ccnd1-/- and Ccnd1+/+ mice (5 weeks of age) were allowed to recuperate for 2 weeks. The mice were assigned to either replacement pellets containing E2 (0.75 mg, 60-day release) or pellet containing placebo. Mice were sacrificed at day 7 after pellet implantation. RNA extracted from mammary glands (3 each group) was labeled and used to probe Affymetrix 430_2.0 arrays.

Description
The CCND1 gene, which is frequently overexpressed in cancers, encodes the regulatory subunit of a holoenzyme that phosphorylates the retinoblastoma protein (pRb). It is known that cyclin D1 regulates ER transactivation using heterologous reporter systems, the significance of this observation to E2 dependent gene activation is unknow. E2 stimulated MCF7 cells treated with cyclin D1 siRNA in order to analyze the genes regulated by estradiol in a cyclin D1 dependent manner. Hormone deprived MCF7 cells were treated with cyclin D1 siRNA or control siRNA and stimulated with E2 or vehicle

Description
Previous studies have suggested that CD133+ cells isolated from human kidney biopsies have the potential to ameliorate injury following intravenous (IV) administration in rodent models of kidney disease by integrating into damaged renal tissue and generating specialised renal cells. However, whether renal engraftment of CD133+ cells is prerequisite for ameliorating injury has not yet been unequivocally resolved. Here, we have established a cisplatin-induced nephropathy model in immunodeficient rats to assess the efficacy of CD133+ human kidney cells in restoring renal health, and to determine the fate of these cells after systemic administration. Specifically, following IV administration, we evaluated the impact of the CD133+ cells on renal function by undertaking longitudinal measurements of the glomerular filtration rate using a novel transcutaneous device. Furthermore, using histological assays, we assessed whether the human kidney cells could promote renal regeneration, and if this was related to their ability to integrate into the damaged kidneys. Our results show that both CD133+ and CD133- cells improve renal function and promote renal regeneration to a similar degree. However, this was not associated with engraftment of the cells into the kidneys. Instead, after IV administration, both cell types were exclusively located in the lungs, and had disappeared by 24 hours. Our data therefore indicate that renal repair is not mediated by CD133+ cells homing to the kidneys and generating specialised renal cells. Instead, renal repair is likely to be mediated by paracrine or endocrine factors.
