The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Self-assembly and semiconductivity of an oligothiophene supergelator

Beilstein Journal of Organic Chemistry, 2010
A bis(trialkoxybenzamide)-functionalized quaterthiophene derivative was synthesized and its self-assembly properties in solution were studied. In non-polar solvents such as cyclohexane, this quaterthiophene π-system formed fibril aggregates with an H ...

On the polar derivative of lacunary type polynomials

Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics
Let $p(z)=a_nz^n+\sum_{l=\nu}^na_{n-l}z^{n-l}$, where $1\leq \nu \leq n$, be a polynomial of degree $n$ having all its zeros in $|z|\leq k\leq 1$. For polar derivative $D_{\alpha}p(z)$, it is known that for each $|\alpha|\leq 1$ on $|z|=1$, \begin{align*} |D_{\alpha}p(z)|\leq \frac{n}{1+k^{\nu}}\Big\{(|\alpha|+k^{\nu})\|p\|_{\infty}-\frac{1 ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Assignments of NMR Spectral Data of a Novel Carbazole-Triazinoindole Based N-Acylhydrazone Derivative

Chinese Journal of Magnetic Resonance, 2020
N-acylhydrazone compounds have two isomers, E/cis and E/trans, in polar solvents. In this work, 1H and 13C nuclear magnetic resonance (NMR) signals, coupling constants (J), and the spatial structures of the two isomers (E/cis and E/trans) of a novel ...

Inequalities for the derivative and polar derivative of lacunary polynomials

Journal of Mathematical Inequalities
Summary: In this paper, we study lacunary polynomials of degree \(n\) having \(s\)-fold zeros at the origin and the remaining zeros lying on or outside the boundary of a prescribed disk. This study in turns gives generalizations and improvements of some well-known results.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Application of M¨obius coordinate transformation in evaluating Newton’s integral

Contributions to Geophysics and Geodesy, 2011
We propose a numerical scheme which efficiently combines various existing methods of solving the Newton’s volume integral. It utilises the analytical solution of Newton’s integral for tesseroid in computing the near-zone contribution to gravitational ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.
