Exploration of heterogeneity and recurrence signatures in hepatocellular carcinoma

open access: yesMolecular Oncology, EarlyView.
This study leveraged public datasets and integrative bioinformatic analysis to dissect malignant cell heterogeneity between relapsed and primary HCC, focusing on intercellular communication, differentiation status, metabolic activity, and transcriptomic profiles.

Composition operators acting on weighted Hilbert spaces of analytic functions [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2015
In this paper, we considered composition operators on weighted Hilbert spaces of analytic functions and  observed that a formula for the  essential norm, gives a Hilbert-Schmidt characterization and characterizes the membership in Schatten-class for ...

Approximation numbers of composition operators on $H^p$ spaces of Dirichlet series [PDF]

open access: yes, 2014
By a theorem of the first named author, φ generates a bounded composition operator on the Hardy space H pof Dirichlet series (1 6 p 1/2 if c0 = 0 and is either identically zero or maps the right half-plane into itself if c0 is positive.

Some revisited results about composition operators on Hardy spaces [PDF]

open access: yes, 2010
We generalize, on one hand, some results known for composition operators on Hardy spaces to the case of Hardy-Orlicz spaces $H^\Psi$: construction of a "slow" Blaschke product giving a non-compact composition operator on $H^\Psi$; construction of a ...

Comparing self‐reported race and genetic ancestry for identifying potential differentially methylated sites in endometrial cancer: insights from African ancestry proportions using machine learning models

open access: yesMolecular Oncology, EarlyView.
Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...

Composition Operators Belonging to Operator Ideals

open access: yesJournal of Mathematical Analysis and Applications, 1999
AbstractWith each composition operator Cϕf=f∘ϕ acting between classical Bergman spaces Ap and Aq, 1≤p, qmax(2/q−2/p,0) and κ∈R there exists a composition operator Cϕ: Ap→Aq whose associated sequence is (equivalent to) k−λ(logk)κ, k≥2. This provides an effective tool to separate quasi-Banach ideals by means of composition operators.

A large‐scale retrospective study in metastatic breast cancer patients using circulating tumour DNA and machine learning to predict treatment outcome and progression‐free survival

open access: yesMolecular Oncology, EarlyView.
There is an unmet need in metastatic breast cancer patients to monitor therapy response in real time. In this study, we show how a noninvasive and affordable strategy based on sequencing of plasma samples with longitudinal tracking of tumour fraction paired with a statistical model provides valuable information on treatment response in advance of the ...

Hyperexpansive composition operators

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 2003
The notion of a completely hyperexpansive operator has been introduced in [ 2 ] by Athavale. In this paper bounded and unbounded hyperexpansive composition operators are investigated. A unique semispectral measure is associated with a bounded completely hyperexpansive composition operator.

Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

open access: yesMolecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important
