Stochastic comparisons of maintenance policies and Bayesian imperfect repair model

, 1994
The types of repairs considered in this research are: (i) perfect repair, (ii) imperfect repair and (iii) minimal repair. When a failed unit is repaired, it is returned to the good-as-new state (perfect repair), is restored to its condition just prior to

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Unreliability of a Standby System with Repair and Imperfect Switching

, 1974
We evaluate and analyze a model of a 2-unit standby system with repair and imperfect switching. The model determines the cumulative probability that system failure occurs in a time interval 0 to T.

Emerging Pronoun Practices After the Procedural Turn: Disclosure, Discovery, and Repair

Sociological Science
We examine emerging practices of pronoun disclosure, discovery, and repair after the procedural turn in pronoun politics, which shifted attention from the substantive question of which pronouns should be used to the procedural question of how preferred ...

AAV-Mediated CRISPR/Cas9 Gene Editing in Murine Phenylketonuria

Molecular Therapy: Methods & Clinical Development, 2020
Phenylketonuria (PKU) due to recessively inherited phenylalanine hydroxylase (PAH) deficiency results in hyperphenylalaninemia, which is toxic to the central nervous system. Restriction of dietary phenylalanine intake remains the standard of PKU care and

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Mapping DNA glycosylase binding across lesion sequence contexts reveals extended sequence and structural recognition logic

Nature Communications
DNA repair of mutagenic lesions is imperfect, allowing mutations to accumulate unevenly across the genome. In base excision repair, glycosylases must locate rare damaged bases embedded in diverse sequence contexts, yet how these contexts shape ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.
