Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
There have been few studies that have focused on the periplaque regions surrounding demyelinated plaques, especially in spinal cords. Areas of incomplete demyelination have been demonstrated but poorly studied. The present study aimed to analyze the molecular immunopathology of periplaque demyelinated lesions (PDLs) in the spinal cord of patients with secondary progressive multiple sclerosis (MS).

- Affymetrix Mouse Gene 2.1 ST Array (mogene21st)
Description
mRNA from wild-type (Cre-) and MLL1-deficient (Cre+) BMDMs were analyzed via gene chip (Mouse Gene ST 2.1, Affymetrix) for relative expression changes. Isolated mRNA from Cre- and Cre+ BMDMs stimulated with classical activation signals (IFNg, LPS or IFNg+LPS) was analyzed using a gene chip panel of >40,000 RefSeq transcripts, and resulting fold expression was determined by analyzing quality-controlled expression values for validated probesets.

- Affymetrix C. elegans Genome Array (celegans)
Description
Our understanding of cellular mechanisms by which animals regulate their response to starvation is limited despite the close relevance of the problem to major human health issues. L1 diapause of Caenorhabditis elegans, where newly hatched first stage larval arrested in response to food-less environment, is an excellent system to study the problem. We found through genetic manipulation and lipid analysis that ceramide biosynthesis, particularly those with longer fatty acid side chains, critically impacts animal survival during L1 diapause. Genetic and expression analyses indicate that ceramide likely regulate this response by affecting gene expression and activity in multiple regulatory pathways known to regulate starvation-induced stress, including the insulin-IGF-1 signaling (IIS) pathway, Rb and other pathways that mediate pathogen/toxin/oxidative stress responses. These findings provide an important insight into the roles of sphingolipid metabolism in not only starvation response but also aging and food-response related human health problems.

- Affymetrix Chicken Gene 1.1 ST Array (chigene11st)
Description
White Striping and Wooden Breast (WS/WB) are abnormalities increasingly occurring in the fillets of high breast yield and growth rate chicken hybrids. These defects lead to consistent economic losses for poultry meat industry, as affected broilers fillets present an impaired visual appearance that negatively affects consumers acceptability. Previous studies have highlighted in affected fillets a deeply damaged muscle, showing profound inflammation, fibrosis and lipidosis. The present study investigated the differentially expressed genes and pathways linked to the compositional changes observed in WS/WB breast muscles, in order to outline a more complete framework of the gene networks related to the occurrence of this complex pathological picture. The biochemical composition was performed on 20 Pectoralis major samples obtained from high breast yield and growth rate broilers (10 affected vs. 10 normal) and 12 out of the 20 samples were used for the microarray gene expression profiling (6 affected vs. 6 normal). The obtained results indicate strong changes in muscle mineral composition, coupled to an increased deposition of fat. In addition, 204 differentially expressed genes (DEG) were found: 102 up-regulated and 102 down-regulated in affected breasts. The gene expression pathways found more altered in WS/WB muscles are those related to muscle development, polysaccharide metabolic processes, proteoglycans synthesis, inflammation and calcium signaling pathway. On the whole, the findings suggest that a multifactorial and complex etiology is associated with the occurrence of WS/WB muscle abnormalities, contributing to further define the transcription patterns associated to these myopathies.

Description
We find significant evidence of the OVOL, AP1, STAT1, STAT3, and NFKB1 TFs having important roles in MET. We prioritize known gene/drug targets for follow-up in the clinic, and show that the AP1/MYC TF pair is a strong candidate for intervention. Overall design: Examination of the effects of OVOL1 and OVOL2 overexpression common to prostate cancer and breast cancer models.
Publication Title
A bioinformatics approach reveals novel interactions of the OVOL transcription factors in the regulation of epithelial - mesenchymal cell reprogramming and cancer progression.

Description
The objective of the overall study was to determine the effects of oral vitamin D supplementation on alveolar macrophages from human subjects. In this substudy, subjects treated with vitamin D (intervention group) in paired analysis had small, but significant effects on immune-related differential gene expression pre versus post supplementation.
