The T cytoplasm of maize serves as a model for the nuclear restoration of cytoplasmic male sterility. The rf2 gene, one of two nuclear genes required for fertility restoration in male-sterile T-cytoplasm (cmsT) maize, was cloned. The protein predicted by the rf2 sequence is a putative aldehyde dehydrogenase, which suggests several mechanisms that might(More)
Some plant cytoplasms express novel mitochondrial genes that cause male sterility. Nuclear genes that disrupt the accumulation of the corresponding mitochondrial gene products can restore fertility to such plants. The Texas (T) cytoplasm mitochondrial genome of maize expresses a novel protein, URF13, which is necessary for T cytoplasm-induced male(More)
BACKGROUND AND PURPOSE Diabetes mellitus (DM) is a major stroke risk factor and is associated with poor recovery compared with nondiabetic stroke patients. In the present study, we investigated the effects of tissue plasminogen activator (tPA) treatment of stroke in diabetic and non-diabetic rats. METHODS Type-1 diabetes (T1DM) was induced by injection of(More)
There is now clear evidence that vitamin D is involved in brain development. Our group is interested in environmental factors that shape brain development and how this may be relevant to neuropsychiatric diseases including schizophrenia. The origins of schizophrenia are considered developmental. We hypothesised that developmental vitamin D (DVD) deficiency(More)
Neovascularization may contribute to functional recovery after neural injury. Combination treatment of stroke with a nitric oxide donor, (Z)-1-[N-(2-aminoethyl)-N-(2-ammonioethyl) amino] diazen-1-ium-1, 2-diolate (DETA-NONOate) and bone marrow stromal cells promotes functional recovery. However, the mechanisms underlying functional improvement have not been(More)
Arteriogenesis supports restored perfusion in the ischemic brain and improves long-term functional outcome after stroke. We investigate the role of endothelial nitric oxide synthetase (eNOS) and a nitric oxide (NO) donor, (Z)-1-[N-(2-aminoethyl)-N-(2-ammonioethyl) amino] diazen-1-ium-1, 2-diolate (DETA-NONOate), in promoting arteriogenesis after stroke.(More)
OBJECTIVE High-mobility group box 1 (HMGB1), an active receptor for advanced glycation endproducts (RAGE), functions as a potent proinflammatory cytokine-like factor that contributes to the pathogenesis of vasculature. Diabetes mellitus (DM) is associated with accelerated development of both microvascular and macrovascular disease and increases the risk of(More)
Apart from its role in regulating calcium there is growing evidence that vitamin D is a neuroactive steroid capable of regulating multiple pathways important for both brain development and mature brain function. Vitamin D induces its genomic effects through its nuclear receptor the vitamin D receptor (VDR). Although there is abundant evidence for this(More)
There is growing evidence that vitamin D is a neuroactive steroid capable of regulating multiple pathways important for both brain development and mature brain function. In particular, there is evidence from rodent models that prenatal vitamin D deficiency alters the development of dopaminergic pathways and this disruption is associated with altered(More)
The present work was designed to study the role of the oncogene product c-Fos in activating the transcription of preproenkephalin (PPE) gene following a kind of peripheral electric stimulation known as electroacupuncture (EA) stimulation. The temporal patterns of rat brain c-fos and PPE mRNA expression were evaluated using the method of Northern blotting,(More)
