Ursolic Acid Impairs Cellular Lipid Homeostasis and Lysosomal Membrane Integrity in Breast Carcinoma Cells

open access: yesCells, 2022
Cancer is one of the leading causes of death worldwide, thus the search for new cancer therapies is of utmost importance. Ursolic acid is a naturally occurring pentacyclic triterpene with a wide range of pharmacological activities including anti ...

Endoplasmic reticulum involvement in yeast cell death [PDF]

open access: yes, 2012
Yeast cells undergo programed cell death (PCD) with characteristic markers associated with apoptosis in mammalian cells including chromatin breakage, nuclear fragmentation, reactive oxygen species generation, and metacaspase activation.

A 3D cell death assay to quantitatively determine ferroptosis in spheroids [PDF]

open access: yes, 2020
The failure of drug efficacy in clinical trials remains a big issue in cancer research. This is largely due to the limitations of two-dimensional (2D) cell cultures, the most used tool in drug screening.

Spatially and temporally defined lysosomal leakage facilitates mitotic chromosome segregation

open access: yesNature Communications, 2020
Lysosomes are intracellular organelles containing degradative enzymes, and leakage of lysosomal contents into the cell is thought to trigger cell death.

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.

Cell death

open access: yesCell
Cell death supports morphogenesis during development and homeostasis after birth by removing damaged or obsolete cells. It also curtails the spread of pathogens by eliminating infected cells. Cell death can be induced by the genetically programmed suicide mechanisms of apoptosis, necroptosis, and pyroptosis, or it can be a consequence of dysregulated ...

Effector Caspase Dcp-1 and IAP Protein Bruce Regulate Starvation-Induced Autophagy during Drosophila Melanogaster Oogenesis [PDF]

open access: yes, 2008
A complex relationship exists between autophagy and apoptosis, but the regulatory mechanisms underlying their interactions are largely unknown. We conducted a systematic study of Drosophila melanogaster cell death–related genes to determine their ...

PTEN modulates EGFR late endocytic trafficking and degradation by dephosphorylating Rab7

open access: yesNature Communications, 2016
Rab7 is a critical GTPase for endosome maturation and it is implicated in the endocytic traffic of several receptors, including EGFR. In this study, the authors reveal the potential role of PTEN in the endocytic trafficking pathway of EGFR, which is ...

Editorial: Yeast cell aging and death [PDF]

open access: yes, 2018
A conspicuous amount of knowledge about the molecular biol- ogy of the cell has come from studies on yeast Saccharomyces cere- visiae, mostly because of its unrivaled qualities as a toolkit for molecular genetics study.

Caspase-independent cell death? [PDF]

open access: yesOncogene, 2002
Many cells die with apoptotic morphology and with documented activation of an effector caspase, but there are also many exceptions. Cells frequently display activation of other proteases, including granzymes, lysosomal cathepsins, matrix metalloproteinases, and proteasomal proteases, and others display morphologies that are not fully consistent with ...
