Recent studies show that AMPA receptor (-R) trafficking is important in synaptic plasticity. However, the signaling controlling this trafficking is poorly understood. Small GTPases have diverse neuronal functions and their perturbation is responsible for several mental disorders. Here, we examine the small GTPases Ras and Rap in the postsynaptic signaling(More)
Dendrobiumofficinale (Orchidaceae) is one of the world's most endangered plants with great medicinal value. In nature, D. officinale seeds must establish symbiotic relationships with fungi to germinate. However, the molecular events involved in the interaction between fungus and plant during this process are poorly understood. To isolate the genes involved(More)
Plant microRNAs (miRNAs) act as negative regulators of gene expression by slicing target transcripts or inhibiting translation. A number of miRNAs play important roles in development. In order to investigate the potential function of miRNAs during male gametogenesis in rice, we obtained both gene and small RNA expression profiles by combining microarray and(More)
Chronic myelogenous leukemia (CML) is characterized by the presence of the chimeric p210bcr/abl oncoprotein that shows elevated and constitutive protein tyrosine kinase activity relative to the normal c-abl tyrosine kinase. Although several p210bcr/abl substrates have been identified, their relevance in the pathogenesis of the disease is unclear. We have(More)
The elucidation of factors that activate the regeneration of the adult mammalian heart is of major scientific and therapeutic importance. Here we found that epicardial cells contain a potent cardiogenic activity identified as follistatin-like 1 (Fstl1). Epicardial Fstl1 declines following myocardial infarction and is replaced by myocardial expression.(More)
Duchenne muscular dystrophy (DMD), the most common inherited muscular dystrophy of childhood, leads to death due to cardiorespiratory failure. Paradoxically, mdx mice with the same genetic deficiency of dystrophin exhibit minimal cardiac dysfunction, impeding the development of therapies. We postulated that the difference between mdx and DMD might result(More)
Accurate quantification of transcript profiling with quantitative real time polymerase chain reaction (qRT-PCR) relies on the reliable normalization of an appropriate reference gene. This study reported the identification and validation of nine reference genes, including β-tubulin (β-TUB), elongation factor 1 alpha (EF-1α), elongation factor 1 beta (EF-1β),(More)
Cyclin-dependent kinases (CDKs) play an essential role in cell cycle regulation during the embryonic and postembryonic development of organisms. To better understand the molecular mechanisms of CDKs involved in embryogenesis regulation in the endangered medicinal plant Dendrobium candidum Wall. ex Lindl., a 1229-bp full-length cDNA of an A-type CDK gene,(More)
Engineering accumulation of triacylglycerol (TAG) in vegetative tissues has been recently proposed as a promising strategy for increasing plant oil production. However, little is known about regulatory mechanisms involved in increasing oil production in plant vegetative tissues. In this study, expression of NtMGD1 encoding a major biosynthetic enzyme for(More)
We observed mitochondrial connexin43 (mtCx43) expression under cerebral ischemia-reperfusion (I/R) injury, analyzed its regulation, and explored its protective mechanisms. Wistar rats were divided into groups based on injections received before middle cerebral artery occlusion (MCAO). Cerebral infarction volume was detected by 2,3,5-triphenyltetrazolim(More)
