Complement plays a critical role in the development of tissue injury in systemic lupus erythematosus. The B6.MRL/lpr mouse, an autoimmune prone mouse, exhibits accelerated and intensified tissue injury in the ischemia/reperfusion (IR) model. It has been demonstrated in nonautoimmune mice that inhibition of complement attenuates inflammatory tissue injury in IR models. The role of complement is ...
Sle1 is a potent autoimmune susceptibility locus on chromosome 1 originally identified in a genome scan of testcross progeny between the systemic lupus erythematosus-prone NZM2410 strain and C57BL/6. We subsequently produced B6.NZMc1, a congenic strain carrying the NZM2410-derived Sle1 genomic interval on the B6 background and demonstrated that Sle1 mediated the loss of tolerance to chromatin i...
PURPOSE Define a role for Fas-FasL in oxygen-induced retinopathy and explore the mechanism of pigment-epithelium-derived growth factor (PEDF) inhibition in this model. METHODS Seven-day-old mice C57BL/6J (B6), FasL-defective (B6-gld), or Fas-defective (B6-lpr) mice were exposed to 75% oxygen for 5 days (postnatal day [P]7-P12) and returned to room air. On day P17, vascular architecture was as...
Folate-mediated one-carbon metabolism (FMOCM) is linked to DNA synthesis, methylation, and cell proliferation. Vitamin B6 (B6) is a cofactor, and genetic polymorphisms of related key enzymes, such as serine hydroxymethyltransferase (SHMT), methionine synthase reductase (MTRR), and methionine synthase (MS), in FMOCM may govern the bioavailability of metabolites and play important roles in the ma...
BACKGROUND The current study was designed to test our hypothesis that atorvastatin could reduce infarct size in intact mice by activating eNOS, specifically the eNOS in bone marrow-derived cells. C57BL/6J mice (B6) and congenic eNOS knockout (KO) mice underwent 45 min LAD occlusion and 60 min reperfusion. Chimeric mice, created by bone marrow transplantation between B6 and eNOS KO mice, underwe...
Genetic variations in the wild-derived inbred mouse strains are more diverse than that of classical laboratory inbred mouse strains, including C57BL/6J (B6). The sleep/wake and monoamine properties of six wild-derived inbred mouse strains (PGN2, NJL, BLG2, KJR, MSM, HMI) were characterized and compared with those of B6 mice. All examined mice were nocturnal and had a polyphasic sleep pattern wi...
Vitamin B6 is a cofactor of various enzymes influencing numerous neurotransmitters in the brain such as norepinephrin, and serotonin. Since these neurotransmitters influence mood, the aim the present work to evaluate the effect of vitamin B6 on depression and obsessive compulsive behavior when coadministred with clomipramine, fluoxetine, or venlafaxine. Male mice weighing 25-30 g were used. The...
PY R I D O X A L 5 -P H O S P H A T E (PLP), the principal active coenzyme form of vitamin B6, is involved in almost 100 enzymatic reactions. One function of vitamin B6 is its role in the 1-carbon metabolic pathway, which involves the transfer of 1-carbon groups for DNA synthesis and DNA methylation. Deficiency of vitamin B6 has been associated with considerably impaired 1-carbon metabolism in ...
PURPOSE The present study was conducted to investigate healing of alkali-burned corneas in MRL/MpJ (MRL) mice. METHODS Gross, clinical, and histologic criteria were used to compare healing of alkali-burned corneas in MRL and control C57BL/6J (B6) mice. Effects of neutrophil depletion of B6 mice and allogeneic reconstitution of B6 mice with MRL bone marrow on wound healing were evaluated. Gene...
