A Tutte Polynomial for Partially Ordered Sets
Journal of Combinatorial Theory, Series B, 1993 We investigate the Tutte polynomial of a greedoid associated to a partially ordered set. In this case, we explore the deletion-contraction formula in two ways and develop an antichain expansion for the polynomial. We show that the polynomial can determine the number of order ideals, order filters and antichains of all sizes of a poset \(P\), but ...

Molecular Oncology, EarlyView.Loss of eIF5A rewires thapsigargin‐mediated endoplasmic reticulum stress responses in multiple myeloma cells by selective translation of mRNA transcripts, consequently dampening thapsigargin‐induced unfolded protein response (UPR) activation and shifting the balance from induction of apoptosis toward cell survival and proliferation.

Metrics on partially ordered sets—A survey
Discrete Mathematics, 1981 AbstractWe review more or less recent results on metrics associated with valuations or (and) minimum weighted paths in posets, metric characterizations of posets and we point out some applications of these results to problems involving uses of distances in social sciences.

Molecular Oncology, EarlyView.This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Partially Ordered Sets Associated with Permutations
European Journal of Combinatorics, 1989 Let \(\Sigma\) be a set of permutations of \([n]=\{1,...,n\}\). A poset P is called chain-permutational with respect to \(\Sigma\) iff the edges of the Hasse diagram of P can be labeled with labels from [n] so that the sequence of labels along each maximal chain of P is a permutation in \(\Sigma\), each permutation in \(\Sigma\) arises exactly once in ...

Molecular Oncology, EarlyView.The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Molecular Oncology, EarlyView.This paper shows that size‐exclusion chromatography and sequential centrifugation applied to seminal plasma enrich for different populations of extracellular vesicles. This may significantly affect the detection and analysis of extracellular vesicle‐associated cancer biomarkers.

On Lattice Embeddings for Partially Ordered Sets
, 1954 Let P be a set partially ordered by a (reflexive, antisymmetric, and transitive) binary relation ≺. Let be the family of all subsets K of P having the property that x ∈ P and y ∈ K and y ≺ x imply x ∈ K.

Engineering IL‐4 resistant proinflammatory human myeloid cells for cancer immunotherapy
Molecular Oncology, EarlyView.We developed a scalable workflow to generate proinflammatory human myeloid cells. CRISPR/Cas9‐edited CD34+ hematopoietic stem and progenitor cells were expanded and differentiated with M‐CSF. Deletion of STAT6 or STAT6/NFKB1 enhanced macrophage proinflammatory gene expression and cytokine secretion in the presence of IL‐4 while maintaining antibody ...
