Project description:The Noda epileptic rat (NER) exhibits generalized tonic–clonic seizures (GTCS). A genetic linkage analysis demonstrated two GTCS-associated loci, Ner1 on Chr 1 and Ner3 on Chr 5. In single-locus congenic lines, neither wild-type Ner1 nor Ner3 allele suppressed GTCS, but both wild-type alleles suppressed GTCS when they were combined in double-locus congenic lines. Global expression analysis showed that Cckbr and St5 locating within Ner1 and Phf24 locating within Ner3 were significantly downregulated. De novo BAC sequencing detected an insertion of an endogenous retrovirus sequence in intron 2 of the Phf24 gene in the NER genome. PHF24 protein was almost absent in the NER brain. It has been known that the Phf24 gene encodes Gαi-interacting protein which is involved in GABAB receptor signaling pathway. Together, we concluded that Cckbr, St5, and Phf24 were strong candidate genes for GTCS in NER.
Project description:Analysis of LBNF1 rat testes from controls, containing both somatic and all germ cell types and from irradiated rats in which all cells germ cells except type A spermatgogonia are eliminated. Results provide insight into distinguishing germ and somatic cell genes and identification of somatic cell genes that are upregulated after irradiation.
Project description:In order to establish a rat embryonic stem cell transcriptome, mRNA from rESC cell line DAc8, the first male germline competent rat ESC line to be described and the first to be used to generate a knockout rat model was characterized using RNA sequencing (RNA-seq) analysis.
