Project description:Whole blood transcriptional profiling of Brazilian patients with acute leptospirosis to identify mechanisms associated with case fatality
Project description:Herein, we aimed to analyze the gene expression profile of medulloblastoma samples from a Brazilian cohort of 17 pediatric patients.
Project description:Here, we used a microarray technique to provide miRNA expression data of a set of 37 adrenocortical tumors (ACT) and 9 non-neoplastic adrenal controls from Brazilian patients assisted in two treatment centers in the state of São Paulo (HC-FMRP-USP and Centro Infantil Boldrini of Campinas).
Project description:MicroRNA-sequencing of the bone marrow samples from Brazilian pediatric patients with B-cell acute lymphoblastic leukemia (B-ALL) and T-cell acute lymphoblastic leukemia (T-ALL).
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 used total RNA of nasopharyngeal swabs from COVID-19 patients to identify their gene expression profile. Multiple biological process were significantly enriched in either asymptomatic or mildly symptomatic patients. These significantly expressed genes were suggested to contribute to the severity of the disease. We also performed metagenomics analysis to identify differences in the microbiome profile of the two groups of patients.
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:The Virochip microarray (version 4.0) was used to detect viruses in patients from North America with unexplained influenza-like illness at the onset of the 2009 H1N1 pandemic. We used metagenomics-based technologies (the Virochip microarray) and deep sequencing to analyze nasal swab samples from individuals with 2009 H1N1 infection. This Series includes the Virochip microarray data only.
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. 13 childhood ACT were analyzed with Illumina HumanCNV370-Duo v1.0 chips. Paired normal blood samples from 6 patients were analyzed with Illumina HumanCNV370-Quad v3.0 chips.
