The noncoding region between tRNAPro and the large conserved sequence block is the most variable region in the mammalian mitochondrial DNA D-loop region. This variable region (ca. 270 bp) of four species of Equus, including Mongolian and Japanese native domestic horses as well as Przewalskii's (or Mongolian) wild horse, were sequenced. These data were(More)
The genetic relationships of seven Japanese and four mainland-Asian horse populations, as well as two European horse populations, were estimated using data for 20 microsatellite loci. Mongolian horses showed the highest average heterozygosities (0.75-0.77) in all populations. Phylogenetic analysis showed the existence of three distinct clusters supported by(More)
The D-loop regions in equine mitochondrial DNA were cloned from three thoroughbred horses by polymerase chain reaction (PCR). The total number of bases in the D-loop region were 1114 bp, 1115 bp and 1146 bp. The equine D-loop region is A/T rich like many other mammalian D-loops. The large central conserved sequence block and small conserved sequence blocks(More)
The in vivo rat brain microdialysis technique with HPLC/UV was used to determine the blood-brain barrier (BBB) penetration of pralidoxime iodide (2-PAM), which is a component of the current nerve agent antidote therapy. After intravenous dosage of 2-PAM (10, 50, 100 mg/kg), 2-PAM appeared dose-dependently in the dialysate; the striatal extracellular/blood(More)
Organ-specific variations in blood group H-like activity were observed in developing radish plants. A temporary increase in serological activity was found to occur in the roots at the earlier stages of development. Arabinogalactan-proteins (AGPs) were isolated from primary and mature roots, and investigated for changes in their physicochemical properties,(More)
In order to contribute to conservation of the endangered Kiso horse, we clarified their genetic information using 31 microsatellite DNAs, and genotyped 125 horses, 83% of the existing breed. First, we clarified the current status of the horses. The horses were confirmed to have experienced rapid loss of population causing a bottleneck, and their effective(More)
Short interspersed repetitive elements (SINEs) were isolated from the equine genome and characterized. The equine SINE (ERE-1) family has several features characteristic of tRNA-derived retroposons. The five members of the equine family of SINEs are approximately 230 nucleotides in length and terminate with a sequence rich in oligo(A). They are all flanked(More)
Employing a combination of reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE) techniques, the complete coding sequence of cDNA for the equine SRY gene was determined. We also attempted to make clear whether the equine SRY gene transcript is expressed in the adult testis, and whether the type of transcript is(More)
A genomic clone isolated from an equine genomic library probed with an oligonucleotide (CAG)10 showed high sequence similarity to the human F18 gene and was tentatively named equine F18 gene. Because the human F18 gene is expressed in many tissues, we examined whether this equine clone was also expressed in equine tissues. The cDNA encoding equine F18 was(More)
