23-Hydroxyursolic Acid Isolated from the Stem Bark of Cussonia bancoensis Induces Apoptosis through Fas/Caspase-8-Dependent Pathway in HL-60 Human Promyelocytic Leukemia Cells

open access: yesMolecules, 2018
The natural product 23-hydroxyursolic acid (23-HUA) is a derivative of ursolic acid, which is known to induce cancer cell apoptosis. However, apoptotic effects and mechanisms of 23-HUA have not been well characterized yet.

Monte Carlo study elucidates the type 1/type 2 choice in apoptotic death signaling in normal and cancer cells [PDF]

open access: yesCells 2013 2:361-392, 2013
Apoptotic cell death is coordinated through two distinct (type 1 and type 2) intracellular signaling pathways. How the type 1/type 2 choice is made remains a fundamental problem in the biology of apoptosis and has implications for apoptosis related diseases and therapy.

Engineering Novel DNA Nanoarchitectures for Targeted Drug Delivery and Aptamer Mediated Apoptosis in Cancer Therapeutics

open access: yesAdvanced Functional Materials, EarlyView.
Designer DNA Architecture‐templated Drug Conjugates (DDA‐DCs) are comprised of a DNA nanomaterial decorated with multiple drug‐loaded DNA aptamers. DDA‐DCs use a combination of multiple aptamer types, each recognizing a different membrane protein to achieve precise targeting of cancer cells.

Modeling the effects of HIV-1 virions and proteins on Fas-induced apoptosis of infected cells [PDF]

open access: yesarXiv, 2007
We report a first in modeling and simulation of the effects of the HIV proteins on the (caspase dependent) apoptotic pathway in infected cells. This work is novel and is an extension on the recent reports and clarifications on the FAS apoptotic pathway from the literature.

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment

open access: yesAdvanced Functional Materials, EarlyView.
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

Non-autonomous consequences of cell death and other perks of being metazoan

open access: yesAIMS Genetics, 2015
Drosophila melanogaster remains a foremost genetic model to study basic cell biological processes in the context of multi-cellular development. In such context, the behavior of one cell can influence another.

Density-based modeling and identification of biochemical networks in cell populations [PDF]

open access: yesarXiv, 2010
In many biological processes heterogeneity within cell populations is an important issue. In this work we consider populations where the behavior of every single cell can be described by a system of ordinary differential equations. Heterogeneity among individual cells is accounted for by differences in parameter values and initial conditions.

Ovarian Function Restoration with Biomimetic Scaffold Incorporating Angiogenic Molecules and Antioxidant in Chemotherapy‐Induced Perimenopausal Model

open access: yesAdvanced Healthcare Materials, EarlyView.
This study developed a biomimetic scaffold incorporating PDRN and melatonin to restore ovarian function in chemotherapy‐induced premature ovarian insufficiency, enhancing cell survival, folliculogenesis, and hormone normalization, while improving fertility rates and offspring in a mouse model, offering a promising strategy for ovarian function ...

A caspase for stress

open access: yesThe Journal of Cell Biology, 2004
Stress in the endoplasmic reticulum (ER)—caused by anything from ischemia to expression of mutant proteins—triggers several responses. Cells slow translation, produce more chaperones, degrade more unfolded proteins, and as a last resort, induce apoptosis. Hitomi et al. (page 347) identify caspase-4 as a critical component of the pathway leading from ER
