- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The aim of this study was to compare the gene expression profile changes breast tumors after the treatment with Anthracyclines and Taxanes. To this end, an oligonucleotide microarray was performed (Affymetrixs HG-U133 Plus 2.0 array). This gene expression study was carried out on the biopsied tumor samples previous being treated with chemotherapy, and subsequently compared with themselves once treatment schedule ended. The post-chemotherapy biopsy was obtained from the surgical piece. The goal of this study was the finding of several genes related to apoptosis, proliferation, differentiation, survival and transformation-related genes and correlating their differences in expression with the degree of response to chemotherapy, determined by the Miller and Payne histological grading system.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
The aim of this study was to compare the gene expression profile changes of DMBA-induced rat breast tumors after treatment with hydroxytyrosol (a natural compound from virgin olive oil). To this end, a cDNA microarray experiment was performed (Affymetrixs Rat Genome 230 2.0 array). This gene expression study was carried out on the tumor biopsy samples prior to hydroxytyrosol treatment, and compared with matched tumor biopsy samples after completion of the hydroxytyrosol treatment schedule. The result of this study was the identification of several genes related to apoptosis, cell cycle arrest, proliferation, differentiation, survival and transformation-related genes.

Description
The aim of this study was to compare the gene expression profile changes of DMBA-induced rat breast tumors from an initial stage to the moment of sacrifice. To this end, a cDNA microarray was performed (Affymetrixs Rat Genome 230 2.0 array). This gene expression study was carried out on the umor biopsy samples and compared with matched tumor biopsy samples once the study ended (7 weeks after initial biopsy).

Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
To study the transcriptional profile of patients with acute RSV or Influenza infection,children of median age 2.4 months (range 1.5-8.6) hospitalized with acute RSV and influenza virus infection were offered study enrollment after microbiologic confirmation of the diagnosis. Blood samples were collected from them within 42-72 hours of hospitalization. We excluded children with suspected or proven polymicrobial infections, with underlying chronic medical conditions (i.e congenital heart disease, renal insufficiency), with immunodeficiency, or those who received systemic steroids or other immunomodulatory therapies. The RSV cohort consisted of 51 patients with median age of 2 months (range 1.5-3.9) and the influenza cohort had 28 patients with median age of 5.5 months (range 1.4-21). Control samples were obtained from healthy children undergoing elective surgical procedures or at outpatient clinic visits. To exclude viral co-infections we performed nasopharyngeal viral cultures of all subjects. We recruited 10 control patients for the RSV cohort with median age of 6.7 months (range 5-10), and 12 control patients for the influenza cohort with median age of18.5 months (range 10.5-26).

Description
Staphylococcus aureus has emerged as a significant pathogen causing severe, invasive disease in otherwise healthy people. Despite considerable advances in understanding the epidemiology, resistance mechanisms, and virulence factors produced by the bacteria, there is limited knowledge of the in vivo host immune response to acute, invasive S. aureus infections. Herein, we report that peripheral blood mononuclear cells from patients with severe S. aureus infections demonstrate a distinctive and robust gene expression profile which is validated in a distinct group of patients and on a different microarray platform. Application of a systems-wide modular analysis framework reveals significant over-expression of innate immunity genes and under-expression of genes related to adaptive immunity. Simultaneous flow cytometry analyses demonstrated marked alterations in immune cell numbers, with decreased central memory CD4 and CD8 T cells and increased number of monocytes. CD14+ monocyte numbers significantly correlated with the gene expression levels of genes related to the innate immune response. These results demonstrate the value of applying a systems biology approach that reveals the significant alterations in the components of circulating blood lymphocytes and monocytes in invasive S. aureus infections.
