Levels of retinol-binding (RBP), the plasma transport protein for vitamin A, were measured by radioimmunoassay in sera and in a large number of tissues from both normal and vitamin A-deficient rats. The tissues included liver, kidney, fat, muscle, brain, eye, salivary gland, thymus, lung, heart, intestine, spleen, adrenal, testes, thyroid, and red blood(More)
Neuronal protein NP25 is a neuron-specific protein present in highly differentiated neural cells, but its functional properties have not been well characterized. NP25 shows high amino acid sequence homology with the smooth muscle cell cytoskeleton-associated proteins, SM22, mp20, and calponin. To gain an insight into the biological functions of NP25, we(More)
We have investigated the modulatory effect of dietary perilla oil which is rich in the n-3 polyunsaturated fatty acid, alpha-linolenic acid, on the development of azoxymethane (AOM)-induced colonic aberrant crypt foci (ACF) in male F344 rats. Animals were given three weekly subcutaneous injections of AOM (15 mg/kg body weight) to induce ACE. The rats were(More)
Liver fibrosis is commonly observed in chronic liver disease. However, the immunological mechanisms underlying hepatic fibrosis due to chronic inflammation are not well defined, mainly because suitable experimental models have not been established. We have found that weekly i.v. administration of concanavalin A (Con A) in BALB/c mice brought about a(More)
A polyclonal antibody was raised against a recombinant ligand binding domain construct of the human retinoid X receptor (RXR) alpha. This antibody reacted with an endogenous 54 kDa nuclear protein from human hepatoma-derived HuH7 cells in immunoblot analyses. Immunoblotting of nuclear proteins from human hepatocellular carcinomas (HCCs) and their(More)
BACKGROUND AND PURPOSE The locus coeruleus (LC) is a major source of noradrenergic projections to the dorsal spinal cord, and thereby plays an important role in the modulation of nociceptive information. The LC receives inputs from substance P (SP)-containing fibres from other regions, and expresses the NK(1) tachykinin receptor, a functional receptor for(More)
Although impaired liver regeneration is thought to be a major cause of death in patients with fulminant hepatitis, the mechanisms are not well defined. Since IL-12 synthesis has been reported to be up-regulated in murine hepatitis virus infection, we studied the influence of continuous IL-12 stimulation on murine liver regeneration using flow cytometric and(More)
The formyl peptide receptors (FPRs) are a family of chemoattractant receptors with important roles in host defense and the regulation of inflammatory reactions. In humans, three FPR paralogs have been identified (FPR1, FPR2, and FPR3) and may have functionally diversified by gene duplication and adaptive evolution. However, the evolutionary mechanisms(More)
We used an evolutionary genomics approach to identify genes that are under lineage-specific positive selection in six species of the genus Bacteroides, including three strains of pathogenic Bacteroides fragilis. Using OrthoMCL, we identified 1275 orthologous gene clusters present in all eight Bacteroides genomes. A total of 52 genes were identified as under(More)
Ten-eleven translocation (TET) proteins, a family of Fe(2+)- and 2-oxoglutarate-dependent dioxygenases, are involved in DNA demethylation. They also help regulate various cellular functions. Three TET paralogs have been identified (TET1, TET2, and TET3) in humans. This study focuses on the evolution of mammalian TET genes. Distinct patterns in TET1 and TET2(More)
