Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Both cellular senescence and organismic aging are known to be dynamic processes that start early in life and progress constantly during the whole life of the individual. In this work, with the objective of identifying signatures of age-related progressive change at the transcriptomic level, we have performed a whole-genome gene expression analysis of peripheral blood leukocytes in a group of healthy individuals with ages ranging from 14 to 93 years. A set of genes with progressively changing gene expression (either increase or decrease with age) has been identified and contextualized in a coexpression network. A modularity analysis has been performed on this network and biological-term and pathway enrichment analyses have been used for biological interpretation of each module. In summary, the results of the present work reveal the existence of a transcriptomic component that shows progressive expression changes associated to age in peripheral blood leukocytes, highlighting both the dynamic nature of the process and the need to complement young vs. elder studies with longitudinal studies that includes middle aged individuals. From the transcriptional point of view, immunosenescence seems to be occurring from a relatively early age, at least from the late 20s/early 30s, and the 49 56 y/o age-range appears to be critical. In general, the genes that, according to our results, show progressive expression changes with aging are involved in pathogenic/cellular processes that have classically been linked to aging in humans: cancer, immune processes and cellular growth vs. maintenance.

Description
The aim of this study was to identify differences in the NK-cell response towards Leishmania mexicana lipophosphoglycan (LPG) between patients with localized (LCL) and diffuse (DCL) cutaneous leishmaniasis through gene expression profiling, in an attempt to pinpoint alterations in the signaling pathways responsible for the NK-cell dysfunction in patients with DCL.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Alterations in the presence of sperm RNAs have been identified using microarrays in teratozoospermic (abnormal morphology) or other types of infertile patients. However, so far no studies had been reported on the sperm RNA content using microarrays in asthenozoospermic patients (low motility).

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
We examined global expression profiles of 7-days old 35S-TrAP transgenic plants compared to Col-0 wild-type using an Affymetrix ATH1 GeneChip and identified 586 genes that are differentially expressed in the 35S-TrAP transgenic plants (q<0.005). Of these, 295 transcripts were elevated whereas 291 were reduced (Figure 2E). We performed real-time PCR and RNA blot assays to validate the microarray results for the differentially expressed genes (DEGs).
