We report a systematic plasmonic study of twisted bilayer graphene (TBLG)-two graphene layers stacked with a twist angle. Through real-space nanoimaging of TBLG single crystals with a wide distribution of twist angles, we find that TBLG supports confined infrared plasmons that are sensitively dependent on the twist angle. At small twist angles, TBLG has a plasmon wavelength comparable to that o...

Epithelial-to-mesenchymal transition (EMT) induced by chronic hypoxia is one of the critical causes of renal fibrosis. Twist, a basic helix-loop-helix transcription factor, is believed to be important in promoting EMT. We found that the expression of Twist was increased in human tubule cell lines (HK-2 and HKC) grown under hypoxic conditions. This was accompanied by reduced expression of the ep...

Most targeted gene mutations are recessive and analyses of gene function often focus on homozygous mutant phenotypes. Here we describe parts of the expression pattern of M-twist in the head of developing wild-type mice and present our analysis of the phenotype of heterozygous twist- null animals at around birth and in adults. A number of twist -null heterozygous mice present skull and limb defe...

BACKGROUND Twist, a basic helix--loop-helix transcription factor, has been reported to be associated with the development and progression of human cancer. We examined the distribution and expression of Twist in cervical cancer to examine its clinical significance. PATIENTS AND METHODS We examined the distribution and expression of Twist in 101 cervical cancer specimens and determined the asso...

The epithelial-mesenchymal transition (EMT) represents a cellular de-differentiation process that provides cells with the increased plasticity required during embryonic development, tissue remodeling, wound healing and metastasis. Slug and Twist are two key EMT transcription factors (EMT-TFs) that are tightly regulated via ubiquitination and degradation. How Slug and Twist escape degradation an...

In a genomewide anoikis suppression screen for metastasis genes, we previously identified the neurotrophic receptor tyrosine kinase TrkB. In mouse xenografts, activated TrkB caused highly invasive and metastatic tumors. Here, we describe that TrkB also induces a strong morphological transformation, resembling epithelial-mesenchymal transition (EMT). This required TrkB kinase activity, a functio...

A set of dynamical equations are derived for a slender tube of isolated magnetic ux generalizing a model due to Spruit. The tube is assumed to consist of eld lines which twist about the tube's axis at some rate q. The equations describe the evolution of the axis and the evolution of the twist. They include the interaction between twist and motions of the axis described as writhing. Through this...

We consider the Melvin Twist of AdS5×S5 under U(1)×U(1) isometry of the boundary S3 of the global AdS5 geometry and identify its field theory dual. We also study the thermodynamics of the Melvin deformed theory. Melvin twist, also known as the T-s-T transformation, is a powerful solution generating technique in supergravity and string theories [1–6]. The procedure relies on having a U(1)× U(1) ...

We give a general treatment of twist-three effects in two-photon reactions. We address the issue of the gauge invariance of the Compton amplitude in generalized Bjorken kinematics and relations of twist-three 'transverse' skewed parton distributions to twist-two ones and interaction dependent three-particle correlation functions. Finally, we discuss leading order evolution of twist-three functi...

Snail1 and Zeb1 are E-cadherin-transcriptional repressors induced during epithelialmesenchymal-transition (EMT). In this article we have analyzed the factors controlling Zeb1 expression during EMT. In NMuMG cells treated with TGF-β, Snail1 RNA and protein are induced one hour after addition of the cytokine preceeding Zeb1 up-regulation that requires six to eight hours. Zeb1 gene expression is c...
