View SamplesTranscriptome analysis of post-mortem brain tissue specimens from three brain regions (BRs), entorinal, temporal and frontal cortices, of 71 Japanese brain-donor subjects to identify genes relevant to the expansion of neurofibrillary tangles. In total, 213 brain tissue specimens (= 71 subjects 3 BRs) were involved in this study. The spreading of neurofibrillary tangles (NFTs), intraneuronal aggregates of highly phosphorylated microtubule-associated protein tau, across the human brain is correlated with the cognitive severity of Alzheimers disease (AD). To identify genes relevant to NFT expansion defined by the Braak stage, we conducted exon array analysis with an exploratory sample set consisting of 213 human post-mortem brain tissue specimens from the entorinal, temporal and frontal cortices of 71 brain-donor subjects: Braak NFT stages 0 (N = 13), III (N = 20), IIIIV (N = 19) and VVI (N = 19). We identified eight genes, RELN, PTGS2, MYO5C, TRIL, DCHS2, GRB14, NPAS4 and PHYHD1, associated with the Braak stage. The expression levels of three genes, PHYHD1, MYO5C and GRB14, exhibited reproducible association on real-time quantitative PCR analysis. In another sample set, including control subjects (N = 30) and patients with late-onset AD (N = 37), dementia with Lewy bodies (N = 17) and Parkinson disease (N = 36), the expression levels of two genes, PHYHD1 and MYO5C, were obviously associated with late-onset AD. Proteinprotein interaction network analysis with a public database revealed that PHYHD1 interacts with MYO5C via POT1, and PHYHD1 directly interacts with amyloid beta-peptide 42. It is thus likely that functional failure of PHYHD1 and MYO5C could lead to AD development.

View SamplesA long form (tRNase ZL) of tRNA 3' processing endoribonuclease (tRNase Z, or 3' tRNase) can cleave any target RNA at any desired site under the direction of artificial small guide RNA (sgRNA). We discovered in human kidney 293 cell extracts various new small noncoding RNAs (ncRNAs) including 5'-half-tRNAs and 28S rRNA fragments, co-immunoprecipitated with tRNase ZL, and demonstrated that two of these ncRNAs work as sgRNAs for tRNase ZL in vivo as well as in vitro. In order to find genuine mRNA targets of tRNase ZL guided by ncRNAs, we performed DNA microarray analysis for mRNAs from the 293 cells transfected with the tRNase ZL expression plasmid, and found that PPM1F and DYNC1H1 mRNAs are its genuine targets.

View SamplesGene expressions relate to the pathogenesis of periodontitis and have a crucial role in local tissue destruction and susceptibility to the disease. The aims of the present study were to explore comprehensive gene expressions/transcriptomes in periodontitis-affected gingival tissues, and to identify specific biological processes.

View SamplesCommon genetic traits are not well defined in hepatocellular carcinoma (HCC), because necroinflammation lasting long in prior to hepatocarcinogenesis embeds highly heterogenous genetic background in hepatocytes over the liver. We experienced a rare case with chronic hepatitis C, in which multiple liver tumors at different stages in multistep hepatocarcinogenesis were observed at the same time. Under the same genetic and etiological backgrounds, comparisons of expression profiles among dysplastic nodules (DN), well differentiated HCC (WEL), and moderately differentiated HCC (MOD) would provide critical genetic information for the initiation and progression of HCC.
