This study was set to study the molecular mechanism underlying how miR-200 regulates EGF/EGFR signaling to involve in epithelial–mesenchymal transition (EMT) in anaplastic thyroid cancer (ATC) cells. Loss-of-function experiments of EGFR silencing by siRNA transfection was performed. Transfection of pre-miR-200s or anti-miR-200s was used to increase or… (More)
The effect of activating 5-lipoxygenase (ALOX5AP) gene polymorphisms on stroke risk may be influenced by the coexistence of modifiable predisposing conditions. We explored the interactions of ALOX5AP polymorphisms and cigarette smoking in a case-control study of patients with atherosclerotic cerebral infarction (ACI). Three polymorphisms of the ALOX5AP gene… (More)
The atmospheric refractive index consists of both real and imaginary parts. The intensity of refractive index fluctuations is generally expressed as the refractive index structure parameter, with the real part reflecting the strength of atmospheric turbulence and the imaginary part reflecting absorption in the light path. A large aperture scintillometer… (More)
Hole-transporting materials with tunable structures and properties are mainly applied in organic light-emitting diodes as transport layer. But their catalytic properties as signal amplifiers in biological assays are seldom reported. In this paper, a starburst molecule, 4,4,4″-tri(N-carbazolyl)-triphenylamine (TCT), containing a triphenylamine as the central… (More)
The effects of foliar spray of putrescine (Put; 8 mM) on chlorophyll (Chl) metabolism and xanthophyll cycle in cucumber seedlings were investigated under saline conditions of 75 mM NaCl. Exogenous Put promoted the conversion of uroporhyrinogen III to protoporphyrin IX and alleviated decreases in Chl contents and in a size of the xanthophyll cycle pool under… (More)
A highly robust MOF based on a 12-carboxyl dendritic aromatic ligand and two Cd clusters is successfully synthesized. This activated MOF exhibits high heat of absorption of CO2 and highly selective adsorption of CO2 over CH4. Especially, a new type of topology (hhm-a) is presented.
A porous aromatic framework (referred as PAF-39) based on tetrakis(4-(9H-carbazol-9-yl)phenyl)methane has been designed and synthesized by oxidative coupling polymerization. PAF-39 exhibits high surface area and high heat of adsorption (Qst ) of CO2 . Especially, the PAF material was applied for non-enzymatic H2 O2 sensing.
The developmental plasticity of leaf size and shape is important for leaf function and plant survival. However, the mechanisms by which plants form diverse leaves in response to environmental conditions are not well understood. Here, we identified TIE1-ASSOCIATED RING-TYPE E3 LIGASE1 (TEAR1) and found that it regulates leaf development by promoting the… (More)
