Autophagy is an evolutionarily conserved process by which cytoplasmic proteins and organelles are catabolized. During starvation, the protein TOR (target of rapamycin), a nutrient-responsive kinase, is inhibited, and this induces autophagy. In autophagy, double-membrane autophagosomes envelop and sequester intracellular components and then fuse with(More)
Oesophageal cancer is one of the most aggressive cancers and is the sixth leading cause of cancer death worldwide. Approximately 70% of global oesophageal cancer cases occur in China, with oesophageal squamous cell carcinoma (ESCC) being the histopathological form in the vast majority of cases (>90%). Currently, there are limited clinical approaches for the(More)
The assumption that each enzyme expresses a single enzymatic activity in vivo is challenged by the linkage of the neuronal enzyme ubiquitin C-terminal hydrolase-L1 (UCH-L1) to Parkinson's disease (PD). UCH-L1, especially those variants linked to higher susceptibility to PD, causes the accumulation of alpha-synuclein in cultured cells, an effect that cannot(More)
Hypoparathyroidism, mental retardation and facial dysmorphism (HRD) is a fatal developmental disease caused by mutations in tubulin-specific chaperone E (TBCE). A mouse Tbce mutation causes progressive motor neuronopathy. To dissect the functions of TBCE and the pathogenesis of HRD, we generated mutations in Drosophila tbce, and manipulated its expression(More)
Synaptic communication requires the controlled release of synaptic vesicles from presynaptic axon terminals. Release efficacy is regulated by the many proteins that comprise the presynaptic release apparatus, including Ca(2+) channels and proteins that influence Ca(2+) channel accumulation at release sites. Here we identify Drosophila RIM (Rab3 interacting(More)
MOTIVATION With the rapid development of next-generation sequencing techniques, metagenomics, also known as environmental genomics, has emerged as an exciting research area that enables us to analyze the microbial environment in which we live. An important step for metagenomic data analysis is the identification and taxonomic characterization of DNA(More)
Acyl-CoA synthetase long-chain family member 4 (ACSL4) converts long-chain fatty acids to acyl-CoAs that are indispensable for lipid metabolism and cell signaling. Mutations in ACSL4 cause nonsyndromic X-linked mental retardation. We previously demonstrated that Drosophila dAcsl is functionally homologous to human ACSL4, and is required for axonal targeting(More)
Basic helix-loop-helix (bHLH) transcription factors (TF) comprise a large group of proteins that are involved in many developmental and physiological processes in plants. In this study, a bHLH gene (PkbHLH2), along with its promoter, was cloned from Populus koreana Rehd. A PkbHLH2 promoter::GUS gene fusion construct was generated to investigate the(More)
An improved understanding of the relative influences of climatic and landscape controls on multiple fire regime components is needed to enhance our understanding of modern fire regimes and how they will respond to future environmental change. To address this need, we analyzed the spatio-temporal patterns of fire occurrence, size, and severity of large fires(More)
