Bacterial communication via quorum sensing (QS) molecules, as well as toxin-antitoxin (TA) gene modules located on bacterial chromosomes are well-studied mechanisms. Escherichia coli mazEF is a stress-induced TA system mediating cell death requiring a QS extracellular death factor (EDF), the pentapeptide NNWNN. MazF is an endoribonuclease specific for ACA sites. During adverse conditions, the activated MazF generates a stress induced translation machinery, composed of MazF-processed mRNAs and selective ribosomes that specifically translate these processed mRNAs.

It is now well accepted that the ionizing radiation-generated reactive oxygen species (ROS), that constitute ~2/3 of the effects of external beam radiation, do not only produce direct tumor cell death, but also affect the surrounding microenvironment. Moreover, this indirect effect of radiation may result in systemic effects, specifically the initiation of an inflammatory response.

Chronic stress exposure is linked to health and performance deficits including mental disorders, chronic diseases, and metabolic conditions. Stress management is an active process of coping with internal or external stressors to prevent or dampen biological and psychological strain

In a recent paper, we introduced a variant of the classical Simeoni tumor growth model, and illustrated its value in assessing tumor growth in a reproducible mouse model for mammary tumors. Our modification consisted of incorporating delay differential equations in the mathematical formulation of the Simeoni model, to represent the delay in drug action often observed under chemotherapeutic or immunotherapeutic regimens.

Phytophthora infestans is the causal agent of late blight disease, which affects potato and tomato crops worldwide, that brings about significant economic losses in the production of these crops. The PITG_06016 gene codes for one of the 7 glucokinases present in this phytopathogen.
