Unraveling the epigenetic code in cancer cell–tumor microenvironment crosstalk

open access: yesMolecular Oncology, EarlyView.
Epigenetic regulation is a key driver of cancer development and progression. Diverse epigenetic alterations in cancer cells and components of the tumor microenvironment (TME) orchestrate their communication through multiple mechanisms. We discuss how the epigenetic code coordinates bidirectional cancer cell–TME crosstalk to promote cancer progression ...

Real convergence and regime-switching among EU accession countries [PDF]

open access: yes, 2008
Real convergence among the ten EU 2004 accession economies is investigated with respect to long-run real interest parity. We employ a novel approach where unit-root tests for real interest differentials are embedded within a Markov regime-switching ...

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

open access: yesMolecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

open access: yesMolecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

NAPRT loss promotes lung tumor initiation and growth through AKT signaling independently of NAD+ biosynthesis

open access: yesMolecular Oncology, EarlyView.
Loss of NAPRT promotes lung tumor initiation and growth through a noncanonical mechanism, independent of its role in NAD+ biosynthesis. Mechanistically, NAPRT depletion activates the mTORC2‐driven AKT/β‐catenin signaling axis to enhance clonogenic and invasive phenotypes. Furthermore, lung‐specific Naprt deletion significantly increases tumor burden in

On the Rate of Moment Convergence for a Normalized Random Walk

open access: yes, 2012
[[abstract]]In this paper, we study the convergence rate of the r-th moments of a normalized simple random walk. When r = 1, we use the discrete-time version of Ito-Tanaka formula to obtain an exact convergence rate.

Rates of convergence for the maximum likelihood estimator in the convolution model [PDF]

open access: yesOpuscula Mathematica, 2006
Rates of convergence for the maximum likelihood estimator in the convolution model, obtained recently by S. van de Geer, are reconsidered and corrected.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

A Note on the Rate of Convergence of the Bootstrap

open access: yesJournal of Approximation Theory, 1993
Suppose \((X_ i)_{i\in\mathbb{N}}\) is an i.i.d. sequence of random variables defined on some probability space \((\Omega,{\mathcal A},\mathbb{P})\) with distribution function (d.f.) \(F\), \(F_{\eta_ n}\) denotes the d.f. of the standardized sample mean \(\eta_ n=\Bigl(\sum^ n_{i=1} X_ i- \mu_ n\Bigr)/(\sigma n^{1/2})\), \(\mu=\mathbb{E}(X_ 1)\) the ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
