Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10
FEBS Letters, EarlyView.Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Solvability of a class of hyperbolic-cosine-type difference equations
Advances in Difference Equations, 2020 We describe a method for constructing one of the basic classes of solvable hyperbolic-cosine-type difference equations, generalizing a known difference equation by Laplace in a natural way.

A Random Difference Equation with Dufresne Variables revisited [PDF]
, 2014 The Dufresne laws (laws of product of independent random variables with gamma and beta distributions) occur as stationary distribution of certain Markov chains $ X_n $ on $ R$ defined by: \begin{equation} X_n = A_n ( X_{n-1} + B_n ) \end{equation ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Some results of ϖ-Painlevé difference equation
Advances in Difference Equations, 2018 In this article, we mainly investigate some properties of two types of difference equations Y(ϖz)+Y(z)+Y(zϖ)=ξz+oY(z)+v $$ Y(\varpi z)+Y(z)+Y\biggl(\frac{z}{\varpi}\biggr)=\frac{\xi z+o}{Y(z)}+v $$ and Y(ϖz)+Y(zϖ)=ξz+oY(z)+vY2(z). $$ Y(\varpi z)+Y\biggl(\

A second-order difference equation with sign-alternating coefficients
Kuwait Journal of Science, 2023 We provide an explicit solution for the terms of the sequence $(x_{n,k})$ defined by $$x_{n,k}= x_{n-1,k} - (-1)^{\lfloor (n-2)/k\rfloor} x_{n-2,k}\, ,$$ for $n\geqslant 3$, setting $x_{1,k}=1$ and $x_{2,k}=0$. Several particular examples are considered.

Difference equation of the colored Jones polynomial for torus knot
, 2004 We prove that the N-colored Jones polynomial for the torus knot T_{s,t} satisfies the second order difference equation, which reduces to the first order difference equation for a case of T_{2,2m+1}.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

On the Difference Equation 𝑥𝑛+1=𝛼+𝑥𝑛−𝑚/𝑥𝑘𝑛
Discrete Dynamics in Nature and Society, 2008 We investigate the global behaviour of the difference equation of higher order 𝑥𝑛+1=𝛼+𝑥𝑛−𝑚/𝑥𝑘𝑛, 𝑛=0,1,…, where the parameters 𝛼,𝑘∈(0,∞) and the initial values 𝑥−𝑚,𝑥−(𝑚−1),…,𝑥−2,𝑥−1, and 𝑥0 are arbitrary positive real numbers.
