40LoVe and Samba are involved in Xenopusneural development and functionally distinct from hnRNP AB
(2014)Heterogeneous nuclear ribonucleoproteins (hnRNPs) comprise a large group of modular RNA-binding proteins classified according to their conserved domains. This modular nature, coupled with a large choice of alternative ...

Coevolution of solid stress and interstitial fluid pressure in tumors during progression: Implications for vascular collapse
(2013)The stress harbored by the solid phase of tumors is known as solid stress. Solid stress can be either applied externally by the surrounding normal tissue or induced by the tumor itself due to its growth. Fluid pressure is ...

Cyst formation in the PKD2 (1-703) transgenic rat precedes deregulation of proliferation-related pathways
(2010)Background: Polycystic Kidney Disease is characterized by the formation of large fluid-filled cysts that eventually destroy the renal parenchyma leading to end-stage renal failure. Although remarkable progress has been ...

Defining the role of solid stress and matrix stiffness in cancer cell proliferation and metastasis
(2018)Solid tumors are characterized by an abnormal stroma that contributes to the development of biomechanical abnormalities in the tumor microenvironment. In particular, these abnormalities include an increase in matrix stiffness ...

Developmental biology: Our fly cousins' gut
(2008)What do we humans have in common with flies? Quite a lot, at least at the cellular and molecular levels. Our intestine, for instance, is similar to that of the fly, not only in function but also in its development and ...

Drosophila melanogaster as a model host for studying Pseudomonas aeruginosa infection
(2009)Conservation of host signaling pathways and tissue physiology between Drosophila melanogaster and mammals allows for the modeling of human host-pathogen interactions in Drosophila. Here we present the use of genetically ...

The effect of the phytoestrogens genistein, daidzein, and equol on the growth of tamoxifen-resistant T47D/PKCα
(2007)Soy supplements are often consumed by women for alleviating menopausal symptoms or for the perceived protective effects against breast cancer. More concerning is the concurrent consumption of soy isoflavones with tamoxifen ...

Embryonic multipotent progenitors remodel the Drosophila airways during metamorphosis
(2010)Adult structures in holometabolous insects such as Drosophila are generated by groups of imaginal cells dedicated to the formation of different organs. Imaginal cells are specified in the embryo and remain quiescent until ...

Familial C3 Glomerulopathy Associated with CFHR5 Mutations: Clinical Characteristics of 91 Patients in 16 Pedigrees
(2011)Background and objectives Complement factor H and related proteins (CFHR) are key regulators of the alternative complement pathway, where loss of function mutations lead to a glomerulopathy with isolated mesangial C3 ...

Genistein as an Inducer of Tumor Cell Differentiation: Possible Mechanisms of Action
(1995)Decreased activity of either topoisomerases or tyrosine kinases has been implicated in the differentiation of a number of cell types. It is therefore conceivable that genistein, because of its reported ability to inhibit ...

Homeostasis in Infected Epithelia: Stem Cells Take the Lead
(2009)To maintain tissue homeostasis and avoid disease, epithelial cells damaged by pathogens need to be readily replenished, and this is mainly achieved by the activation of stem cells. In this Short Review, we discuss recent ...

Article
The HPV16 oncogenes cause aberrant stem cell mobilization
(2013)Human Papilloma Virus related epithelial cancers have been speculated to derive from virus-infected tissue stem cells. Stem cells also are thought to provide a reservoir of latently infected cells that can persist for long ...

Identification of biomarkers that distinguish human papillomavirus (HPV)-positive versus HPV-negative head and neck cancers in a mouse model
(2006)Head and neck squamous cell carcinoma (HNSCC) is a leading cause of cancer mortality worldwide. Recent reports have associated a subset of HNSCC with high-risk human papillomaviruses (HPVs), particularly HPV16, the same ...

Induction of caspase-independent programmed cell death by vitamin E natural homologs and synthetic derivatives.
(2009)Current observations in the literature suggest that vitamin E may be a suitable candidate for cancer chemotherapy. To investigate this further, we examined the ability of the vitamin E natural homologs [alpha-, beta-, ...

The Ink4/Arf locus is a barrier for iPS cell reprogramming
(2009)The mechanisms involved in the reprogramming of differentiated cells into induced pluripotent stem (iPS) cells by the three transcription factors Oct4 (also known as Pou5f1), Klf4 and Sox2 remain poorly understood. The ...

Insulin-mimetic action of vanadium compounds on osteoblast-like cells in culture
(1997)Vanadium compounds mimic insulin actions in different cell types. The present study concerns the insulin-like effects of three vanadium(V) derivatives and one vanadium(IV) complex on osteoblast-like (UMR106 and MC3T3E1) ...

Multiscale biphasic modelling of peritumoural collagen microstructure: The effect of tumour growth on permeability and fluid flow
(2017)We present an in-silico model of avascular poroelastic tumour growth coupled with a multiscale biphasic description of the tumour–host environment. The model is specified to in-vitro data, facilitating biophysically realistic ...

Article
Multiscale modelling of solid tumour growth: the effect of collagen micromechanics
(2016)Here we introduce a model of solid tumour growth coupled with a multiscale biomechanical description of the tumour microenvironment, which facilitates the explicit simulation of fibre–fibre and tumour–fibre interactions. ...

Mutant polycystin-2 induces proliferation in primary rat tubular epithelial cells in a STAT-1/p21-independent fashion accompanied instead by alterations in expression of p57KIP2 and Cdk2
(2008)Background. Autosomal Dominant Polycystic Kidney Disease (ADPKD) is characterized by the formation of multiple fluid-filled cysts that destroy the kidney architecture resulting in end-stage renal failure. Mutations in genes ...
