Project description:The development of precision medicine strategies requires prior knowledge of the genetic background of the target population. However, despite the availability of data from admixed Americans within large reference population databases, we cannot use these data as a surrogate for that of the Brazilian population. This lack of transferability is mainly due to differences between ancestry proportions of Brazilian and other admixed American populations. To address the issue, a coalition of research centres created the Brazilian Initiative on Precision Medicine (BIPMed), an initiative of five Research Innovation and Dissemination Centers (RIDCs) supported by FAPESP.
Project description:We showed that Brazilian green propolis attenuated Aβ-induced memory and learning impairment. Comprehensive gene expression analysis demonstrated that Brazilian green propolis treatment suppressed inflammation and immune responses via immune cells such as microglia and astrocytes in the brain. These results indicate the potential of Brazilian green propolis as a promising ingredient for preventing AD-type dementia.
Project description:SNP array data from 13 Brazilian childhood adrenocortical tumors (ACTs) were analyzed to detect recurrent copy number changes and highlight potential candidate driver genes.
Project description:Gut microbes elicit specific changes in gene expression in the colon of mice. We colonized germ-free mice with microbial communities from the guts of humans, zebrafish and termites, human skin and tongue, soil and estuarine microbial mats. We used microarrays to detail the differences in global gene expression in colon tissue that are caused by the different microbial communities 28 days after gavage into the germfree animal.
Project description:a. After collection, live termites were brought to geneOmbio Technologies Central Processing Laboratory under controlled room temperature (25.9C, 72% RH) until dissection was made. The termites selected for analysis were collected from Pune region (18°31′13″N 73°51′24″E) from the state of Maharashtra, India. These were identified as Hypotermes xenotermitis based on mitochondrial COI gene sequencing. b. Based on the morphological features the insects were segregated into two groups (a) workers (b) soldiers c. Ten termites from each group were anaesthetized on ice and immediately dissected for isolation of mandibular glands (circled) using sterile scalpel, blade and petri plate. d. The glands were transferred in two milliliter sterile Tris HCl buffer (pH 7.0) containing 0.1 M NaCl for SDS-PAGE analysis. Duplicate samples were collected for each workers and soldiers. Hence total four protein samples were prepared. e. The sample was homogenized with a teflon pestle homogenizer and stored at -20 C till use.

Project description:Methylation differences between SIC 5 cocoa seedlings germinated in a common environment before growth for 74 days under semic controlled environmental conditions set to mimic the Malaysian or Brazilian temperature environment. Genomic DNA sonicated and the methylated fraction enriched using a 5-methylcytosine antibody before whole genome amplification and hybridisation to the array. Two-condition experiment, Methyl enriched gDNA Malaysian vs. Brazilian leaf samples. 7 Biological replicates independently grown and harvested. Environmental (temperature) effect
