Tumor Resistance Explained by Hormesis

open access: yesDose-Response, 2010
Enhanced drug (GDC 0449) resistance in a mouse model for human medulloblastoma is shown in the present paper to act via an hormetic response. This has significant implications, imposing constraints on the quantitative features of the dose response of the

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Interaction between Short-Term Heat Pretreatment and Fipronil on 2 Instar Larvae of Diamondback Moth, (Linn)

open access: yesDose-Response, 2010
Based on the cooperative virulence index ( c.f. ) and LC 50 of fipronil, the interaction effect between short-term heat pretreatment and fipronil on 2 nd instar larvae of diamondback moth (DBM), Plutella xylostella (Linnaeus), was assessed.

Compound Optimal Designs for Percentile Estimation in Dose-Response Models with Restricted Design Intervals [PDF]

open access: yes
In dose-response studies, the dose range is often restricted due to ethics concerns over drug toxicity and/or efficacy, particularly when human subjects are involved.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Radiation Responses of Human Mesenchymal Stem Cells Derived From Different Sources

open access: yesDose-Response, 2019
Mesenchymal stem cells (MSCs) derived from different tissues may aid in the regeneration of radiation-induced organ lesions; however, the radiation responses of human MSCs from different sources are unknown. In our study, a comparison of the results from

Optimal designs for dose finding studies [PDF]

open access: yes
Identifying the "right" dose is one of the most critical and difficult steps in the clinical development process of any medicinal drug. Its importance cannot be understated: selecting too high a dose can result in unacceptable toxicity and associated ...

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

What Can Chemical Carcinogenesis Shed Light on the LNT Hypothesis in Radiation Carcinogenesis?

open access: yesDose-Response, 2019
To protect the public’s health from exposure to physical, chemical, and microbiological agents, it is important that any policy be based on rigorous scientifically based research. The concept of “linear no-threshold” (LNT) has been implemented to provide
