Project description:We identified a Mariner transposase helix-turn-helix (HTH) DNA-binding domain that was captured in the Caenorhabditis genus by a subset of F-box genes, which we refer to as F-box A2 genes. The origin of F-box A2 genes likely occurred through a single transposase capture event, followed by an increase in copy number. We focused on fbxa-215, a F-box A2 gene highly expressed in the C. elegans germline and embryos, and that localizes to germ granules in embryos. The HTH domain of FBXA-215 is required for fertility and displays predominantly a signature of purifying selection, highlighting the importance of this domain. As the HTH domain of FBXA-215 is related to the DNA-binding HTH domain of transposases, we reasoned that FBXA-215 may bind to DNA in C. elegans and thus regulate gene expression at the transcriptional level. We performed mRNA sequencing of young adults and embryos to test this, but found no clear deregulation of protein-coding genes and transposable elements upon complete deletion of fbxa-215.

Project description:This study investigates the medical and psychosocial consequences of colorectal cancer on adolescents and young adults. Measuring physical function in adolescents and young adults with colorectal cancer may help doctors better understand the level of physical function during cancer treatment and how to improve the management of colorectal cancer in adolescents and young adults. This study may also help design a future exercise program to decrease risk factors including high blood pressure, high blood sugar, and high cholesterol.
Project description:In type 1 diabetes (T1D), impaired insulin sensitivity may contribute to the development of diabetic kidney disease (DKD) through alterations in kidney oxidative metabolism. Young adults with T1D and healthy controls underwent single-cell RNA sequencing, and spatial metabolomics to assess this relationship.
Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to GO and rGO on nematode, Caenorhabditis elegans. We performed whole genome DNA microarray experiments using age synchronized young adult C. elegans population exposed to GO and rGO for 24h. We used whole genome microarrays to screen for global changed in C. elegans transcription profiles and with subsequent quantitative analysis conducted on selected genes. Young adults of C.elegans were selected for RNA extraction and hybridization on Affymetrix microarrays.
