Aberrant expression of Lin28 and let-7 has been observed in many human malignancies. However, its functions and underlying mechanisms remain largely elusive. Here we show that aberrant expression of Lin28 and let-7 facilitates aerobic glycolysis, or Warburg effect, in cancer cells. Mechanistically, we discover that Lin28A and Lin28B enhance, whereas let-7(More)
BACKGROUND Epidermal growth factor receptor (EGFR) inhibitors are mainly used for the targeted therapy of non-small cell lung cancer (NSCLC). Therefore, EGFR mutations should be detected to treat lung cancer. The aim of this study is to determine the detection rate of NSCLC in patients with EGFR gene mutations by conducting direct sequencing and ARMS assay.(More)
Fear memory formation is thought to require dopamine, brain-derived neurotrophic factor (BDNF) and zinc release in the basolateral amygdala (BLA), as well as the induction of long term potentiation (LTP) in BLA principal neurons. However, no study to date has shown any relationship between these processes in the BLA. Here, we have used in vitro whole-cell(More)
Cell-cycle-related proteins, such as cyclins or cyclin-dependent kinases, may have functions beyond that of cell cycle regulation. The expression and translocation of cyclinD1-CDK4 in post-mitotic neurons indicate that they may have supplementary functions in differentiated neurons that might be associated with neuronal plasticity. In the present study, our(More)
Rett syndrome (RTT) arises from loss-of-function mutations in methyl-CpG binding protein 2 gene (Mecp2), but fundamental aspects of its physiological mechanisms are unresolved. Here, by whole-cell recording of synaptic responses in MeCP2 mutant mice in vivo, we show that visually driven excitatory and inhibitory conductances are both reduced in cortical(More)
BACKGROUND The growing applications of nanotechnologic products, such as quantum dots (QDs), increase the likelihood of exposure. Furthermore, their accumulation in the bioenvironment and retention in cells and tissues are arousing increasing worries about the potentially harmful side effects of these nanotechnologic products. Previous studies concerning QD(More)
NaOH was used to disintegrate a mixture composed mainly of primary sludge with biofilm sludge before anaerobic digestion in batch experiments. NaOH pretreatment dissolved some organic substances, and the optimum dose was 0.1mol/L. After the alkali-treated sludge was fed into the digesters, the higher pH delayed the start of digestion and reduced the biogas(More)
Competing mechanisms of long-term potentiation (LTP) and long-term depression (LTD) in principal neurons of the basolateral amygdala (BLA) are thought to underlie the acquisition and consolidation of fear memories, and their subsequent extinction. However, no study to date has examined the locus of action and/or the cellular mechanism(s) by which these(More)
Synaptic plasticity is the ability of synapses to modulate the strength of neuronal connections; however, the molecular factors that regulate this feature are incompletely understood. Here, we demonstrated that mice lacking brain-specific angiogenesis inhibitor 1 (BAI1) have severe deficits in hippocampus-dependent spatial learning and memory that are(More)
Genetic studies have revealed significant overlaps of risk genes among psychiatric disorders. However, it is not clear how different mutations of the same gene contribute to different disorders. We characterized two lines of mutant mice with Shank3 mutations linked to ASD and schizophrenia. We found both shared and distinct synaptic and behavioral(More)
