Project description:Glomerular expression data from human kidney biopsy in African American subjects with glomerulopathies We used microarrays to analyze the transcriptome of African American subjects with glomerulopathies and the association of expression with APOL1 risk alleles (G1 and G2)
Project description:Tubulointersitial expression data from human kidney biopsy in African American subjects with glomerulopathies We used microarrays to analyze the transcriptome of African American subjects with glomerulopathies and the association of expression with APOL1 risk alleles (G1 and G2)
Project description:This study investigates the presence of specific fibrosis-associated gene expression signatures in Crohn's disease patient biopsies.
Project description:Women of sub-Saharan African descent have disproportionately higher incidence of Triple Negative Breast Cancer (TNBC), and TNBC-specific mortality. Population comparative studies show racial differences in TNBC biology, including higher prevalence of basal-like and Quadruple-Negative subtypes in African Americans (AA). However, previous investigations relied on self-reported race (SRR) of primarily United States (US) populations. Due to heterogenous genetic admixture, and biological consequences of social determinants, the true association of African ancestry with TNBC biology is unclear. To address this, we conducted RNAseq on an international cohort of AAs, west and east Africans with TNBC. Using comprehensive genetic ancestry estimation in this African-enriched cohort, we found expression of 613 genes associated with African ancestry and 2000+ associated with regional African ancestry. A subset of African-associated genes also showed differences in normal breast tissue. Pathway enrichment and deconvolution of tumor cellular composition revealed tumor-associated immunological profiles are distinct in patients of African descent.
Project description:In Crohn's disease, creeping fat is the characteristic expansion of mesenteric adipose tissue wrapping around the inflamed intestine. Through a comparative transcriptomic analysis of creeping fat and normal-looking mesenteric adipose tissues from patients with Crohn's disease and non-Crohn's disease, we found that a dynamic transcriptional and cell compositional change occurs during the progression from non-Crohn's disease to Crohn's disease, and finally to creeping fat.
