Project description:The BEECH study enrolled 297 children with stunting or wasting in Misisi, Lusaka. This is a sub-study of n=30 RNAseq datasets from intestinal biopsies from children undergoing endoscopy who had failed to respond to a nutritional intervention
Project description:This study aimed to analyze the whole-blood transcriptome profile of fit children with overweight/obesity (OW/OB) compared to unfit children with OW/OB. Methods: 27 children with OW/OB (10.14 ± 1.3 years, 59% boys) from the ActiveBrains project were evaluated. VO2peak was assessed using a gas analyzer, and participants were categorized into fit or unfit according to the CVD risk-related cut-points. Whole-blood transcriptome profile (RNA sequencing) was analyzed. Differential gene expression analysis was performed using Limma R/Bioconductor software package (analyses adjusted by sex and maturational status). Results: 256 genes were differentially expressed in fit children with OW/OB compared to unfit children with OW/OB after adjusting by sex and maturational status (FDR < 0.05). Enriched pathways analysis identified gene pathways related to inflammation (e.g., dopaminergic and GABAergic synapse pathways). Conclusion: The distinct pattern of whole-blood gene expression in fit children with OW/OB reveals genes and gene pathways that might play a role in reducing CVD risk factors later in life.
Project description:The miRNA expression profile in the body circulation of obese children differs from normal children.Thirty-six differential expression miRNAs were screened by gene chip, and seven up-regulated miRNAs were verified by TaqMan qPCR This result is attributed to the abnormal metabolism of obese children. hsa-miR-15b-5p and hsa-miR-223-3p could serve as a molecular marker for screening obese children and susceptible population of metabolic syndrome.
Project description:According to the status of children acute lymphoblastic leukemia,we collected samples from the new dignosed, complete remmission and relapsed.
