Project description:To compare the splenic macrophages between SIRPα-knockout mice and WT mice, we performed a complete transcript profiling of the splenic red pulp macrophages from SIRPα-KO mice compared to WT mice using mRNA microarray as a discovery platform. SIRPα-KO mice and WT mice were kept under the same condition. Macrophages were isolated from spleen red pulp of SIRPα-KO mice and WT mice. RNA was then isolated from the same number of freshly isolated macrophages.
Project description:To investigate the roles of Klf3 in B lymphopoiesis, CD19+ B cells were sorted from the spleens of WT and Klf3 KO mice (Molecular and Cellular Biology (2008); 28:3967–3978). Following RNA extraction, gene expression was compared in WT and Klf3 KO CD19+splenic B cells using Affymetrix microarrays.

Project description:The experiment elucidates the development of splenic B- and T lymphocytes in the absence of a vital gene. For this purpose, spleen cells of 5 wild type and 5 full knock-out mice were depleted of red blood cells and prepared for 10x single cell RNA-Seq sequencing. The library was prepared according to the manufacturers instructions.
Project description:Tristetraprolin (TTP) binds to specific AU-rich elements in the 3'UTR of certain transcripts and regulates post-transcriptional gene expression by increasing the rate of mRNA turnover. In this study, we evaluated the effects of TTP deficiency on the overall gene expression of spleen tissue, in order to discover tissue specific targets of TTP under normal physiologic conditions. We utilized "Triple KO" (Zfp36-/-/TNFR1-/-/TNFR2-/-) mice that are deficient in TTP and two TNF receptors and compared the transcriptomic changes to "Double KO" (TNFR1-/-/TNFR2-/-) and WT mice. Spleen mRNA from four WT, four "Double KO", and four "Triple mice" was subjected to RNA-Seq in two phases. All the animals used in this study were males between the ages of 12-14 weeks and were on a mixed (75% C57BL/6NTac, 25% 129/SVEV) background. Examination of splenic gene expression difference between "Triple KO"-WT and "double KO"-WT data sets
Project description:The PR-domain family (PRDMs) encodes transcriptional regulators, several of which are deregulated in cancer. We found that loss of Prdm11 accelerates MYC-driven lymphomagenesis in the Eµ-Myc mouse model. Expression data from EμMyc;Prdm11 WT and EμMyc;Prdm11 KO end-stage splenic tumors to identify genes deregulated by loss of Prdm11 9 EμMyc;Prdm11 WT and 9 EμMyc;Prdm11 KO end-stage splenic tumors
