Project description:The Deciphering the Mechanisms of Developmental Disorders (DMDD) programme analyses the morphological and molecular phenotypes of embryonic and perinatal lethal mouse mutant lines. Here we show that single whole embryo RNA-seq of 73 mouse mutant lines (>1000 transcriptomes) uncovers transcriptional events underlying embryonic lethality and associates previously uncharacterised genes with specific pathways and tissues. Further, we separate embryonic delay signatures from line-specific transcriptional changes by developing a baseline mRNA expression catalogue of wild-type mice during somitogenesis. Collectively, this work provides a rich resource to further our understanding of early embryonic developmental disorders.

Project description:The DMDD Programme (Deciphering the Mechanisms of Developmental Disorders) provides a free online database of morphological and molecular phenotypes from embryonic-lethal mouse gene knockouts (http://www.dmdd.org.uk/). Embryos are imaged using HREM, placentas are examined by histology and mutant embryo mRNA expression profiles are compared to wild type. Total RNA was extracted from somite number staged homozygous mutant, heterozygous and sibling wild-type E9.5 whole C57BL/6N embryos and DNase treated. The embryos were derived from Mouse Genetics Programme gene knockout lines defined as homozygous embryonic lethal (http://www.sanger.ac.uk/science/collaboration/mouse-resource-portal).

Project description:The DMDD Programme (Deciphering the Mechanisms of Developmental Disorders ) provides a free online database of morphological and molecular phenotypes from embryonic-lethal mouse gene knockouts (http://www.dmdd.org.uk/).

To underpin these investigations we have produced a comprehensive time series of gene expression through normal embryo development.

Project description:2-Dodecyl-6-Methoxycyclohexa-2, 5 -Diene-1,4-Dione (DMDD) was purified from the roots of Averrhoa carambola L. Previous research demonstrated that DMDD is a small molecular compound with significant therapeutic potential for diabetes. However, the efficacy of DMDD to ameliorate diabetic cognitive impairment in type 2 diabetes mice has not been reported. In present study, we detected gene expression profiles in the hippocampi of diabetic db/db mice after DMDD treatment. 9-week-old male db/db mice were treated with DMDD (50 mg/kg) for 28 days followed by Y maze and novel object recognition test for behavioral evaluation. Our results showed that DMDD attenuated the spatial working memory and object recognition memory impairment in db/db mice. Using mouse lncRNA array analysis, 11 lncRNAs and 4 mRNAs with significant differential expression were identified after DMDD treatment. Among these, Hif3a expression was significantly increased in the hippocampi of diabetic db/db mice compared with db/m control mice and then decreased after DMDD treatment. Besides, DMDD treatment reduced tau protein expression, the formation of a-synuclein oligomers and high glucose-induced apoptosis in the hippocampi of db/db mice and high glucose-treated HT22 cells. DMDD protected neural cells from apoptosis by repression of Hif3a. These data suggest that DMDD can alleviate cognitive impairment by regulating apoptosis through the pro-apoptotic protein Hif3a. In conclusion, our study suggests that DMDD has great potential to be a new preventive and therapeutic compound for diabetic cognitive impairment.
