Difference Equations in Massive Higher Order Calculations
, 2007 The calculation of massive 2–loop operator matrix elements, required for the higher order Wil-son coefficients for heavy flavor production in deeply inelastic scattering, leads to new types of multiple infinite sums over harmonic sums and related ...

CEACAM1 participation in breast cancer progression
Molecular Oncology, EarlyView.In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Oscillation of higher-order delay difference equations
Advances in Difference Equations, 2006 The oscillation and asymptotic behavior of the higher-order delay difference equation , n = 0,1,2,..., are investigated. Some sufficient conditions of oscillation and bounded oscillation of the above equation are obtained.

INITIAL AND BOUNDARY VALUE PROBLEMS FOR DIFFERENCE EQUATIONS [PDF]
We consider initial and boundary value problems for linear nonhomogeneous difference equations with constant coefficients. For such problems we compute the numerical values of the solutions using the discrete deconvolution.

Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Molecular Oncology, EarlyView.Partial inhibition of focal adhesion kinase (FAK) can paradoxically promote tumor growth, rather than simply producing a weaker antitumor effect than that observed with strong FAK suppression. In breast cancer and melanoma models, targeting p110δ PI3K, particularly in macrophages, counteracted these tumor‐promoting effects, highlighting the importance ...

Differential equations with a difference quotient
Electronic Journal of Differential Equations, 2017 The purpose of this paper is to study a class of ill-posed differential equations. In some settings, these differential equations exhibit uniqueness but not existence, while in others they exhibit existence but not uniqueness.

Linearizable Exact and Explicit Analytic Solutions for Riccati Differential Equations
In this paper, linearizable exact and explicit analytic solutions for classical Riccati differential equations are investigated in the complex field C by locally reducing the equations to other q-difference-differential equations and constructing ...

Molecular 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 ...
