Cells of the osteoblast lineage affect the homing and the number of long-term repopulating haematopoietic stem cells, haematopoietic stem cell mobilization and lineage determination and B cell lymphopoiesis. Osteoblasts were recently implicated in pre-leukaemic conditions in mice. However, a single genetic change in osteoblasts that can induce(More)
The gene encoding pyrethroid-hydrolyzing esterase (EstP) from Klebsiella sp. strain ZD112 was cloned into Escherichia coli and sequenced. A sequence analysis of the DNA responsible for the estP gene revealed an open reading frame of 1914 bp encoding for a protein of 637 amino acid residues. No similarities were found by a database homology search using the(More)
The pyrethroid pesticides residues on foods and environmental contamination are a public safety concern. Pretreatment with pyrethroid hydrolase has the potential to alleviate the conditions. For this purpose, a fungus capable of using pyrethroid pesticides as a sole carbon source was isolated from the soil and characterized as Aspergillus niger ZD11. A(More)
MicroRNAs (miRNAs) have been implicated in the maintenance of the cancer stem cell (CSC) phenotype via their ability to affect expression of genes and proteins that regulate cell proliferation and/or cell death. Thus, identification of CSC-related miRNAs would provide information for a better understanding of (More)
Brachypodium distachyon (Brachypodium) is a temperate wild grass species and is a powerful model system for studying grain, energy, forage and turf grasses. Exploring the natural variation in the drought response of Brachypodium provides an important basis for dissecting the genetic network of drought tolerance. Two experiments were conducted in a(More)
We have cloned a novel KRAB-related zinc finger gene, ZNF307, encoding a protein of 545aa. ZNF307 is conserved across species in evolution and is differentially expressed in human adult and fetal tissues. The fusion protein of EGFP-ZNF307 localizes in the nucleus. Transcriptional activity assays show ZNF307 suppresses transcriptional activity of(More)
Transplantation of olfactory ensheathing cells has been one of the promising strategies in enhancing central nerve fiber regeneration. Membrane surface molecules on olfactory ensheathing cells mediating cell-cell interactions as well as various factors released from them are thought to be important for nerve regeneration. The latter, however, has not been(More)
Drought is a major environmental stress limiting growth of perennial grasses in temperate regions. Plant drought tolerance is a complex trait that is controlled by multiple genes. Candidate gene association mapping provides a powerful tool for dissection of complex traits. Candidate gene association mapping of drought tolerance traits was conducted in 192(More)
OBJECTIVE Cell-matrix interactions promote cartilage homeostasis. We previously found that Smad1, the transcriptional modulator of the canonical bone morphogenetic protein 7 (BMP-7) pathway, interacted with the cytoplasmic domain of CD44, the principal hyaluronan receptor on chondrocytes. To elucidate the physiologic function of CD44-Smad1 interactions, as(More)
