Mechanosensory neurons (SNs) of Aplysia form synapses in culture with some targets (L7), but not others (L11), even when a SN is plated with both targets. We examined whether branch-specific net export of mRNA encoding synapse-specific molecules might contribute to branch-specific synapse formation. Single-cell RT-PCR was used to assay levels of mRNA(More)
In addition to protein-coding genes, the human genome makes a large amount of noncoding RNAs, including microRNAs and long noncoding RNAs (lncRNAs). Both microRNAs and lncRNAs have been shown to have a critical role in the regulation of cellular processes such as cell growth and apoptosis, as well as cancer progression and metastasis. Although it is well(More)
Morphological changes are thought to contribute to the expression of long-term synaptic plasticity, a cellular basis for learning and memory. The mechanisms mediating the initiation and maintenance of the morphological changes are poorly understood. We repeatedly imaged the axonal arbors of mechanosensory neurons of Aplysia as they formed new synaptic(More)
Long noncoding RNAs (lncRNAs) have been shown to regulate tumor biology and might be used for cancer diagnosis, prognosis and potential therapeutic targets. Although up-regulation of lncRNA UCA1 (urothelial carcinoma-associated 1) in several cancers has been found, its role in gastric cancer remains elusive. The aim of this study was to detect the(More)

MicroRNAs (miRNAs) are approximately 22 nucleotide non-coding RNA molecules that regulate gene expression post-transcriptionally. Although aberrant expression of miRNAs in various human cancers suggests a role for miRNAs in tumorigenesis, it remains largely unclear as to whether knockdown of a specific miRNA affects tumor growth. In this study, we profiled(More)
Functional genomics studies have led to the discovery of a large amount of non-coding RNAs from the human genome; among them are long non-coding RNAs (lncRNAs). Emerging evidence indicates that lncRNAs could have a critical role in the regulation of cellular processes such as cell growth and apoptosis as well as cancer progression and metastasis. As master(More)
High-intensity focused ultrasound (HIFU) is a noninvasive treatment that induces complete coagulative necrosis of a tumour at depth through the intact skin. This study was to explore the possibility of using HIFU for the treatment of patients with localised breast cancer in a controlled clinical trial. A total of 48 women with biopsy-proven breast cancer(More)
To explore mechanisms of long-term, pathway-specific synaptic plasticity, we examined consequences of differential stimulation of Aplysia sensorimotor connections in culture where two sensory neuron (SN) inputs converge on a single target motor cell L7. A single pairing of tetanus in one SN with bath application of 5-HT evoked long-term (24 hr) increase in(More)
Quantitative trait loci (QTL) for carcass and meat quality traits were detected in a sample of 224 progeny from four males in line VI and 12 females in line V of Beijing ducks. These lines were selected for high body weight at 42 days of age (line VI) or high egg production at 360 days of age (line V). Traits were weights of the carcass, head, neck, shanks,(More)
