Nap1L4a Cooperates with Scl/Klf1 to Recruit H2A.Z in Mediating Interactions Among Cis‐Regulatory Elements and Transcription Required for Primitive Erythropoiesis in Zebrafish

open access: yesAdvanced Science, EarlyView.
Nap1l4a is required in erythropoiesis and hypoxia responses via physical interaction with Klf1 and Scl to recruit the histone variant H2A.Z. This facilitates its associated cis‐regulatory element (CRE) remodeling and the consequent chromatin assembly, and activates the transcription of erythroid lineage‐specific genes.

Requiring that Minimal Separators Induce Complete Multipartite Subgraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2018
Complete multipartite graphs range from complete graphs (with every partite set a singleton) to edgeless graphs (with a unique partite set). Requiring minimal separators to all induce one or the other of these extremes characterizes, respectively, the ...

Partitioning Chordal Graphs

open access: yesElectronic Notes in Discrete Mathematics, 2011
Matrix partition problems generalize graph colouring and homomorphism problems and occur frequently in the study of perfect graphs. It is difficult to decide, even for a small matrix M, whether the M-partition problem is polynomial time solvable or NP-complete (or possibly neither), and whether M-partitionable graphs can be characterized by a finite ...

Clique Graphs of Chordal and Path Graphs [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 1994
Clique graphs of chordal and (undirected) path graphs are characterized. The clique graph of a graph \(G\) is the intersection graph of maximal cliques of \(G\). A chordal graph is the intersection graph of subtrees of a tree. A path graph is the intersection graph of paths of a tree. (Given a family \(F\) of subsets, the intersection graph of \(F\) is

On Hyper-Chordal graphs [PDF]

open access: yesCarpathian Journal of Mathematics, 2021
Triangulated graphs have many interesting properties (perfection, recognition algorithms, combinatorial optimization algorithms with linear complexity). Hyper-triangulated graphs are those where each induced subgraph has a hyper-simplicial vertex. In this paper we give the characterizations of hyper-triangulated graphs using an ordering of vertices and

Toughness and hamiltonicity in $k$-trees [PDF]

open access: yes, 2001
We consider toughness conditions that guarantee the existence of a hamiltonian cycle in $k$-trees, a subclass of the class of chordal graphs. By a result of Chen et al.\ 18-tough chordal graphs are hamiltonian, and by a result of Bauer et al.\ there ...

A Polynomial Delay Algorithm for Enumerating Minimal Dominating Sets in Chordal Graphs [PDF]

open access: yesInternational Workshop on Graph-Theoretic Concepts in Computer Science, 2014
An output-polynomial algorithm for the listing of minimal dominating sets in graphs is a challenging open problem and is known to be equivalent to the well-known Transversal problem which asks for an output-polynomial algorithm for listing the set of ...
