Project description:It is well-known that between 40 and 50% of patients taking antidepressants do not respond to treatment or relapse. Genome wide gene expression studies can help us to understand better the response to antidepressants, revealing the effects of both genetic background and environmental/epigenetic factors. We used microarrays to detail the response to Fluoxetine in children and adolescents, analysing the expression just before intake of drug and 8 weeks after starting the treatment.
Project description:The goal of this observational population-based cohort study is to investigate the clinical characteristics and outcomes of children and adolescents with primary gastrointestinal malignancies registered in the publicly available Surveillance, Epidemiology, and End Results (SEER) 17 database during 2000-2019.
Project description:This study included whole-genome DNA methylation data from 64 whole-blood samples from patients recruited from the Hospital Psiquiatrico Infantil Juan N. Navarro in Mexico City. The project explored epigenetic changes associated with eating disorders in children and adolescents from a Mexican population.
Project description:Fifty-six children and adolescents with type 1 diabetes at least one year after diagnosis, aged 6-17 years old and fifty-six healthy age- and sex-matched subjects were enrolled in this cross-sectional study. Tear samples were collected using Schirmer strips placed on the lower eyelid. The proteomic analysis was based on a detergent-assisted protein extraction and their digestion from the tears, analysis of the tryptic peptides with LC-MS/ enabling the identification, and quantification of the Shirmer strip protein content via DIA-NN, and subsequently the statistical and bioinformatic analysis using the R and Metascape enrichment analysis tool.
Project description:The gene expression patterns in the dentate gyrus of wild-type mice treated with fluoxetine (15 mg/kg/day for 3 weeks) or vehicle were examined using Affymetrix GeneChip arrays.
Project description:The gene expression patterns in the medial prefrontal cortex of wild-type mice treated with fluoxetine (15 mg/kg/day for 3 weeks) or vehicle were examined using Affymetrix GeneChip arrays.
Project description:Outcome of paediatric B-cell Non-Hodgkin Lymphoma (B-NHL) has significantly improved in the last decades due to risk adapted strategies and the addition of immunotherapy, (survival >90%). However, limited progress has been achieved in relapsed patients, mostly Burkitt lymphoma (<30%). Validation of prognostic biomarkers to identify candidates to novel therapies is imperative. This retrospective study reports on clinical and therapeutic data of 46 children and adolescents with relapsed B-NHL, including integrative molecular data of 16 (35%) cases. TP53 alterations were identified in 10 (60%) patients which were associated with worse outcome. Our data support the focus on TP53 as a potential biomarker.
Project description:DNA methylation profiles from saliva collected from 89 mothers and 179 adolescent children who received or did not receive perinatal folic acid supplementation Periconceptional folic acid supplementation and DNA methylation patterns in adolescents
