Project description:FAN (Factor associated with neutral sphingomyelinase activation) is an adaptor protein that constitutively binds to TNF-R1. Microarray analysis was performed in fibroblasts derived from wild-type or FAN knockout mouse embryos to evaluate the role of FAN in TNF-induced gene expression. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes during this process. Keywords: genetic modification
Project description:FAN (Factor associated with neutral sphingomyelinase activation) is an adaptor protein that constitutively binds to TNF-R1. Microarray analysis was performed in fibroblasts derived from wild-type or FAN knockout mouse embryos to evaluate the role of FAN in TNF-induced gene expression. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes during this process. Experiment Overall Design: MEFs were derived from C57BL/6 embryos that were either wild type or FAN-/-. Cells were either grown in DMEM 0%FCS for 24h or DMEM 0% FCS for 8h followed by incubation in DMEM 0% FCS containing 50ng/ml TNF for 16h. These four conditions were each used to generate total RNA (RNeasy MidiKit, Qiagen) which was sent to AROS applied biotechnology (Sweden) for Affymetrix GeneChip Mouse Genome 430 2.0 Array analysis.
Project description:Purpose of this experiment was to study the host-transcriptional response to MA-15, MA-15epsilon, and MA-15-gamma in both young and aged mice to further understand the differences between response within each age group, and the age-related differences in response to each virus.
Project description:The purpose of this study was to identify differentially-expressed genes between WT MA-10 mouse tumor Leydig cells and MA-10 cells in which the steroidogenic acute regulatory protein (STAR) is knocked out.
Project description:The oldest authenticated peptide sequences to date were reported in 2016 from 3.8 Ma old ostrich eggshell (OES) from the site of Laetoli, Tanzania (Demarchi et al., 2016). Here we demonstrate survival of the same sequences in 6.5-9Ma OES recovered from a palaeosteppe setting in northwestern China. The eggshell is thicker than those observed in extant species and consistent with the Liushu Struthio sp. ootaxon. These findings push the preservation of ancient proteins back to the Miocene and highlight their potential for paleontology, paleoecology and evolutionary biology.
