An object of the present invention is to develop and provide a lung cancer differential marker with which lung cancer can be diagnosed conveniently and highly sensitively without depending only on increase or decrease in protein expression level between cancer patients and healthy persons. Another object of the present invention is to develop and provide a glycan marker capable of distinguishing histological types of lung cancer. Of serum glycoproteins, glycopeptide and glycoprotein groups whose glycan structures were altered specifically in lung cancer cell culture supernatants were identified, and they are provided as lung cancer differential markers.

The present invention provides a novel artificial mimic miRNA utilizing miRNA. An artificial mimic miRNA is a single-stranded nucleic acid including: a X region; and a Y region, the Y region and the X region being linked, wherein the X region is a guide strand sequence of a mature miRNA or a partial sequence of the guide strand sequence of the mature miRNA and consists of a linking side region (X_(B)) and a non-linking side region (X_(F)) to the Y region, the linking side region (X_(B)) is a sequence that does not cause intramolecular annealing within its region, and the Y region is a sequence that intramolecularly anneals to the non-linking side region (X_(F)) of the X region. According to the artificial mimic miRNA of the present invention, the expression of the target gene can be inhibited.


Humanin is a 24-amino acid, secreted bioactive peptide that prevents various types of cell death and improves some types of cell dysfunction. Humanin inhibits neuronal cell death that is caused by a familial Alzheimer’s disease (AD)-linked gene via binding to the heterotrimeric Humanin receptor (htHNR). This suggests that Humanin may play a protective role in AD-related pathogenesis. Calmodulin-like skin protein (CLSP) has recently been identified as a physiological agonist of htHNR with 105-fold more potent anti-cell death activity than Humanin. Humanin has also shown to have protective effects against some metabolic disorders. In this review, the broad range of functions of Humanin and the functions of CLSP that have been characterized thus far are summarized.

The present invention provides a new artificial match-type miRNA utilizing miRNA. A single strand nucleic acid containing X region and Y region, wherein the 3-terminal of the X region and the 5-terminal of the Y region are linked via a linker region of a non-nucleotide structure, the X region contains a guide strand sequence of a mature miRNA, and the Y region contains a sequence completely complementary to the X region is an artificial match-type miRNA. The artificial match-type miRNA can suppress expression of the target gene.

Toll-like receptor 9 (TLR9) is an innate immune sensor for microbial DNA that erroneously responds to self DNA in autoimmune disease. To prevent autoimmune responses, Toll-like receptor 9 is excluded from the cell surface and silenced until the N-terminal half of the ectodomain (TLR9N) is cleaved off in the endolysosome. Truncated Toll-like receptor 9 (TLR9C) senses ingested microbial DNA, although the precise role of the truncation remains controversial. Here we show that TLR9 is expressed on the surface of splenic dendritic cells. Following the cleavage of TLR9 in the endolysosome, N-terminal half of the ectodomain remains associated with truncated TLR9, forming the complex TLR9N+C. The TLR9-dependent cytokine production by Tlr9(-/-) dendritic cells is rescued by a combination of TLR9N and TLR9C, but not by TLR9C alone. These results demonstrate that the TLR9N+C complex is a bona fide DNA sensor.

Two amino acids (lysine at position 627 or asparagine at position 701) in the polymerase subunit PB2 protein are considered critical for the adaptation of avian influenza A viruses to mammals. However, the recently emerged pandemic H1N1 viruses lack these amino acids. Here, we report that a basic amino acid at position 591 of PB2 can compensate for the lack of lysine at position 627 and confers efficient viral replication to pandemic H1N1 viruses in mammals. Moreover, a basic amino acid at position 591 of PB2 substantially increased the lethality of an avian H5N1 virus in mice. We also present the X-ray crystallographic structure of the C-terminus of a pandemic H1N1 virus PB2 protein. Arginine at position 591 fills the cleft found in H5N1 PB2 proteins in this area, resulting in differences in surface shape and charge for H1N1 PB2 proteins. These differences may affect the protein's interaction with viral and/or cellular factors, and hence its ability to support virus replication in mammals.


Keloid is a dermal fibroproliferative growth that results from dysfunction of the wound healing processes. Through a multistage genome-wide association study using 824 individuals with keloid (cases) and 3,205 unaffected controls in the Japanese population, we identified significant associations of keloid with four SNP loci in three chromosomal regions: 1q41, 3q22.3-23 and 15q21.3. The most significant association with keloid was observed at rs873549 (combined P = 5.89 x 10(-23), odds ratio (OR) = 1.77) on chromosome 1. Associations on chromosome 3 were observed at two separate linkage disequilibrium (LD) blocks: rs1511412 in the LD block including FOXL2 with P = 2.31 x 10(-13) (OR = 1.87) and rs940187 in another LD block with P = 1.80 x 10(-13) (OR = 1.98). Association of rs8032158 located in NEDD4 on chromosome 15 yielded P = 5.96 x 10(-13) (OR = 1.51). Our findings provide new insights into the pathophysiology of keloid formation.

MAP kinase (MAPK) modules are conserved three-kinase cascades that serve central roles in intracellular signal transduction in eukaryotic cells. MAPK pathways of different inputs and outputs use overlapping sets of signaling components. In yeast, for example, three MAPK pathways (pheromone response, filamentous growth response, and osmostress adaptation) all use the same Ste11 MAPK kinase kinase (MAPKKK). How undesirable leakage of signal, or cross-talk, is prevented between these pathways has been a subject of intensive study. This review discusses recent findings from yeast that indicate that there is no single mechanism, but that a combination of four general strategies (docking interactions, scaffold proteins, cross-pathway inhibition, and kinetic insulation) are utilized for the prevention of cross-talk between any two MAPK modules. © 2010 Elsevier Ltd.
