The Kashaev Equation and Related Recurrences [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2019 The hexahedron recurrence was introduced by R. Kenyon and R. Pemantle in the study of the double-dimer model in statistical mechanics. It describes a relationship among certain minors of a square matrix. This recurrence is closely related to the Kashaev equation, which has its roots in the Ising model and in the study of relations among principal ...

Nutrition and Breast Cancer: A Literature Review on Prevention, Treatment and Recurrence
Nutrients, 2019 Breast cancer (BC) is the second most common cancer worldwide and the most commonly occurring malignancy in women. There is growing evidence that lifestyle factors, including diet, body weight and physical activity, may be associated with higher BC risk.

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential
Molecular Oncology, EarlyView.In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.

Recurrence relations for the Sheffer sequences [PDF]
Linear Algebra and its Applications, 2012 AbstractIn this paper, using the production matrix of an exponential Riordan array [g(t),f(t)], we give a recurrence relation for the Sheffer sequence for the ordered pair (g(t),f(t)). We also develop a new determinant representation for the general term of the Sheffer sequence.

Molecular Oncology, EarlyView.Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.

Recurrence relations based on minimization
Journal of Mathematical Analysis and Applications, 1974 AbstractThis paper investigates solutions of the general recurrence M(0) = g(0), M(n + 1) = g(n + 1) + min0⩽k⩽n(αM(k) + βM(n − k)) for various choices of α, β, and g(n). In a large number of cases it is possible to prove that M(n) is a convex function whose values can be computed much more efficiently than would be suggested by the defining recurrence.

Complete Asymptotic Analysis of a Nonlinear Recurrence Relation with Threshold Control
, 2010 We consider a three-term nonlinear recurrence relation involving a nonlinear filtering function with a positive threshold . We work out a complete asymptotic analysis for all solutions of this equation when the threshold varies from to . It is found that

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence
Molecular Oncology, EarlyView.The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

Systematic profiling of cancer‐fibroblast interactions reveals drug combinations in ovarian cancer
Molecular Oncology, EarlyView.Fibroblasts, cells in the tumor environment, support ovarian cancer cell growth and alter morphology and drug response. We used fibroblast and cancer cell co‐culture models to test 528 drugs and discovered new drugs for combination treatment. We showed that adding Vorinostat or Birinapant to standard chemotherapy may improve drug response, suggesting ...
