Genomic characteristics of RARRES1 wild type and knockout mice lung tissues

ABSTRACT: Purpose: RARRES1 is proposed as tumor suppressor gene but its function is not clear yet. To elucidate RARRES1 function in carcinogenesis, we examine phenotype and genetic characteristics of the RARRES1 genetically knockout mice lung. Methods: Genetic profiles of RARRES1 wild type and knockout mouse lung tissues of embryonic day 19.5, 10-month-old, and 18-month-old mice were analyzed by whole genome and RNA sequencing in triplicate, using Illumina Hiseq X ten. Additionally, three lung tumors originated from RARRES1 knockout mice also examine using same platform. Results: RARRES1 knockout accelerate spontaneous lung carcinogenesis, with pluripotency of stem cells, Hippo signaling pathway, Wnt signaling pathway, and cell cycle related genes are significantly activated including Nanog, CDK1, Cyclin E. In addition, RARRES1 knockout induced lung cancer had rare oncogenic mutations, on the contrary, lung tissue progenitor cell, lung bipotent progenitor cell and AT2 type cell popularity increased. Conclusions: RARRES1 knockout accelerate spontaneous lung carcinogenesis through organ stem cell population enhancement with various stemness related gene set activation beside rare mutational driving.

Soluble RARRES1 induces podocyte apoptosis to promote glomerular disease progression

Project description:We try to explore the effect of RARRES1 on human podocyte, so we performed RARRES1 overexpression and knockdown experiments. cell mRNA profiles of human human podocyte cell lines transfected with RARRES1 overexpression vectors orcontrol vectors; and cells transfected with RARRES1 shRNA lentivirus or scramble shRNA lentivirus and stimulated with TNFa (10ng/ml) or without TNFa for 24 hours were generated by deep sequencing, in triplicate, using Illumina GAIIx. The sequence reads that passed quality filters were analyzed at the transcript. We found that most differentially expressed genes (DEGs) are enriched with cell migration and apoptosis-related pathways, also DEGs stimulated by TNFα but suppressed by RARRES1 knockdown, were also enriched with cell cycle-related pathways.These data suggest that RARRES1 plays a key role in the regulation of cell cycle and apoptosis, consistent with its role as a tumor suppressor gene.

IQGAP2 knockout model of hepatocellular carcinoma

Project description:Whole body knockout mice lacking IQ-motif containing GTPase-activating protein 2 (IQGAP2) develop spontaneous hepatocellular carcinoma (HCC) at the age of 12 months and older (Schmidt et al., 2008). Hepatic transcript expression profiles were obtained for IQGAP2 knockout and wild-type control mice of two age groups, 6- and 24-month-old. Liver samples from 24-month-old IQGAP2 knockout mice were HCC tumors, livers from all other groups were tumor-free. Results provide insights into the potential role of IQGAP2 as a liver-specific tumor suppressor. Transcript profiles of four groups of mouse livers (N = 3 in each group) were compared using Affymetrix GeneChip® Mouse Genome 430 2.0 Array. The groups included livers from 6- and 24-month-old wild-type (WT) mice and 6- and 24-month-old (KO) Iqgap2-/- mice.

Expression data from Gprc5a wild type or knockout mouse tracheal epithelial cells (MTECs)

Project description:Gprc5a is a lung tumor suppressor gene. Gprc5a-knockout (ko) mice can develop spontaneous lung cancer and Gprc5a-ko mouse model is relevant to human lung cancer. Thus, exploration of the mechanisms underlying lung tumorigenesis in Gprc5a-ko mice would be very helpful for revealing those in human lung cancer. We used microarrays to detail the global gene expression profile that underlies oncogenesis by Gprc5a-knockout gene deletion in mouse tracheal epithelial cells. Wild type and gene-knockout mouse tracheal epithelial cells that were divided into two groups were used for RNA extraction.

Arginase 1 deletion in myeloid cells decreases immune suppression and tumor formation in pancreatic cancer

Project description:We deleted Arginase 1 in myeloid cells in a spontaneous pancreatic cancer mouse model. We sequenced the spontaneous pancreatic tumor generated by an 11-month-old KF mouse (Ptf1aFlpO/+;KrasFrt-STOP-Frt-G12D/+) and an 11-month-old KFCA mouse (Ptf1aFlpO/+;KrasFrt-STOP-Frt-G12D/+;LysMcre;Arg1f/f). Single cell RNA sequencing revealed macrophage reprogramming and increase CD8+ T cell infiltration upon deletion of Arginase 1 in myeloid cells.

Single-cell transcriptional analysis of kidney from aging mice with podocyte specific RARRES1 overexpression

Project description:Retinoic acid receptor responder protein-1 (RARRES1) was identified as a podocyte transmembrane protein whose expression correlates with glomerular disease progression. The cytopathic effect of RARRES1 is carried out only when proteolytically cleaved in its ectodomain into a soluble form (sRARRES1) and subsequently endocytosed by podocytes, as a membrane-bound, cleavage site mutant failed to induce any effect. We investigated the effects of long-term podocyte-derived RARRES1 overexpression on aging-induced kidney injury.

Microarray analysis of the effects of TNFAIP8 and RARRES1 on global gene expression in prostate cancer PC3 cells against empty vector control

Project description:Tumor necrosis factor-α-inducible protein 8 (TNFAIP8) is a TNF-α inducible anti-apoptotic protein involved in tumor growth and survival. The effect and biological significance of TNFAIP8 over-expression on the global gene expression in prostate cancer PC3 cells was analysed. Retinoic Acid Receptor Responder (RARRES1)/ Tazarotene-induced gene-1 (TIG-1) is a putative tumor suppressor gene. The effect of RARRES1 over-expression on the global gene expression was also analysed in order to determine the significance of RARRES1 in prostate cancer PC3 cells.

Mechanisms of CS-related A/J lung tumorigenesis

Project description:The A/J mouse is highly susceptible to lung tumor induction and has been widely used as a screening system in carcinogenicity testing and chemoprevention studies. However, the A/J mouse model has several disadvantages. Most notably, it develops tumors spontaneously. Moreover, there is a considerable gap in our understanding of the underlying mechanisms of pulmonary chemical carcinogenesis in the A/J mouse. Therefore, we examined the differences between spontaneous and cigarette smoke-related lung tumors in the A/J mouse using transcriptomics and microRNA (miRNA) profiling. Male A/J mice were exposed whole-body to mainstream cigarette smoke (MS) for 18 months. Gene expression analysis of lung tumors and surrounding non-tumorous parenchyma samples from animals that were exposed to either 300 mg/m3 MS or sham-exposed to fresh air indicated significant differential expression of 296 genes. Ingenuity Pathway Analysis illustrated an overall suppression of the humoral immune response, which was accompanied by a disruption of sphingolipid and glycosaminoglycan metabolism in tumors of MS-exposed A/J mice. Thus, we propose that MS exposure leads to severe perturbations in pathways essential for tumor recognition by the immune system, thereby potentiating the ability of tumor cells to escape from immune surveillance. Further, exposure to MS appeared to affect expression of miRNA which have previously been implicated in carcinogenesis and are thought to contribute to tumor progression. Finally, we identified a 50-gene signature and show its utility in distinguishing between the cigarette smoke-related and spontaneous lung tumors.
