p53 directly regulates the glycosidase FUCA1 to promote chemotherapy-induced cell death [PDF]

open access: yes, 2016
p53 is a central factor in tumor suppression as exemplified by its frequent loss in human cancer. p53 exerts its tumor suppressive effects in multiple ways, but the ability to invoke the eradication of damaged cells by programmed cell death is considered

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

A non-linear mathematical model of cell turnover, differentiation and tumorigenesis in the intestinal crypt [PDF]

open access: yesJournal of Theoretical Biology (2007) 244(3):367-377, 2013
We present a development of a model of the relationship between cells in three compartments of the intestinal crypt: stem cells, semi-differentiated cells and fully differentiated cells. Stem and semi-differentiated cells may divide to self-renew, undergo programmed death or progress to semi-differentiated and fully differentiated cells respectively ...

External and internal triggers of cell death in yeast [PDF]

open access: yes, 2016
In recent years, yeast was confirmed as a useful eukaryotic model system to decipher the complex mechanisms and networks occurring in higher eukaryotes, particularly in mammalian cells, in physiological as well in pathological conditions.

Spot‐14 and its paralog Spot‐14R regulate expression of metabolic and thermogenic pathway genes in murine brown and beige adipocytes

open access: yesFEBS Letters, EarlyView.
Spot‐14 and Spot‐14R play distinct roles in regulating metabolism in brown and beige adipocytes. While both influence lipid and glucose pathways, Spot‐14 uniquely controls thermogenic gene expression. This dual regulation balances energy storage and heat production, highlighting potential therapeutic targets for obesity and metabolic disorders. Spot 14

Persistent random walk of cells involving anomalous effects and random death [PDF]

open access: yes, 2014
The purpose of this paper is to implement a random death process into a persistent random walk model which produces subballistic superdiffusion (L\'{e}vy walk). We develop a Markovian model of cell motility with the extra residence variable $\tau .$ The model involves a switching mechanism for cell velocity with dependence of switching rates on $\tau $.

Autophosphorylation at serine 166 regulates RIP kinase 1-mediated cell death and inflammation [PDF]

open access: yes, 2020
Receptor interacting protein kinase 1 (RIPK1) regulates cell death and inflammatory responses downstream of TNFR1 and other receptors, and has been implicated in the pathogenesis of inflammatory and degenerative diseases.

The ARTS of Cell Death [PDF]

open access: yesJournal of Cell Death, 2019
Although much is known regarding intestinal stem cell (ISC) self-renewal and differentiation, the specific mechanisms used for their elimination is unclear. We recently discovered that the pro-apoptotic protein ARTS, a Septin4 isoform, interacts with X-linked inhibitor of apoptosis (XIAP) in the ISC niche to regulate stem cell survival during ...

STAT3 expression is reduced in cardiac pericytes in HFpEF and its loss reduces cellular adhesion and induces pericyte senescence

open access: yesFEBS Letters, EarlyView.
Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.

Impact of aging : sporadic, and genetic risk factors on vulnerability to apoptosis in Alzheimer's disease [PDF]

open access: yes, 2003
The identification of specific genetic (presenilin-1 [PS1] and amyloid precursor protein [APP] mutations) and environmental factors responsible for Alzheimer's disease (AD) has revealed evidence for a shared pathway of neuronal death.
