Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

APOBEC3 activity and DNA polymerase‐ε deficiency are associated with distinct IDH1 R132 hotspot mutations

open access: yesMolecular Oncology, EarlyView.
Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.

Bridging the gap: a genetically validated avian chorioallantoic membrane platform for investigation of spontaneous circulating tumor cells

open access: yesMolecular Oncology, EarlyView.
We established the avian chorioallantoic membrane (CAM) assay as a scalable in vivo model for studying circulating tumor cells (CTCs). Human gastrointestinal tumors spontaneously released genetically validated CTCs that were detected across multiple platforms, demonstrating that the CAM model provides an accessible tool for investigating early cancer ...

Genetic drift in genetic algorithm selection schemes [PDF]

open access: yesIEEE Transactions on Evolutionary Computation, 1999
A method for calculating genetic drift in terms of changing population fitness variance is presented. The method allows for an easy comparison of different selection schemes and exact analytical results are derived for traditional generational selection, steady-state selection with varying generation gap, a simple model of Eshelman's CHC algorithm ...

Rett syndrome and genetic drift

Brain and Development, 1999
An X chromosome gene is assumed to be responsible for the cause of Rett syndrome (RS). However, new genealogical observations suggest involvement of autosomal recessive gene(s) as well, at least in familial cases. To account for these and other recent observations, the theoretical model presented in 1990 by the authors of this paper is applied to the ...

Dominance and Genetic Drift

Crop Science, 2003
Many public sector maize recurrent selection programs have been designed based on additive genetic expectations. Populations have been managed as large metapopulations with the assumption that population size must be very large because inbreeding due to finite size causes a linear reduction in genetic variance; we show that in BS13(S)C0 such ...

Genetic drift: A case of abuse

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, 2015
In this essay, an infant with multiple fractures is removed from the custody of her parents because of suspected child abuse. Subsequently studies reveal that the child has osteogenesis imperfecta, type III. Though the child is eventually returned to the mother's custody, her entire first year has been spent in foster care.

The Effect of Genetic Drift in a Young Genetically Isolated Population

Annals of Human Genetics, 2005
SummaryThe genetic make‐up of genetically isolated populations may differ from a general population as a result of genetic drift and founder effects. We assessed the extent of this deviation in a recently isolated population located in the southwest of the Netherlands and studied as part of the Genetic Research in Isolated Population (GRIP) program.
