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

arXiv, 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.

Caspase-9 mediates Puma activation in UCN-01-induced apoptosis

Cell Death and Disease, 2014
The protein kinase inhibitor 7-hydroxystaurosporine (UCN-01) is one of the most potent and frequently used proapoptotic stimuli. The BH3-only molecule of Bcl-2 family proteins has been reported to contribute to UCN-01-induced apoptosis.

Sepsis is a syndrome with hyperactivity of TH17-like innate immunity and hypoactivity of adaptive immunity [PDF]

arXiv, 2013
Currently, there are two major theories for the pathogenesis of sepsis: hyperimmune and hypoimmune. Hyperimmune theory suggests that cytokine storm causes the symptoms of sepsis. On the contrary, hypoimmune theory suggests that immunosuppression causes the manifestations of sepsis.

Morphometric‐Assisted Prediction of Developmental Toxicity Using Stem Cell‐Based Embryo Models in Microwells

Advanced Healthcare Materials, EarlyView.
This proof‐of‐concept study involves high‐throughput teratogenicity screening of compounds using XEn/EpiCs, a 3D stem cell‐based embryo model, within microwells. The term ‘morphotoxicity’ is introduced to complement traditional cytotoxicity assays through automated feature extraction and machine‐learning‐assisted classification of morphologies.

Triptolide inhibits Epstein-Barr nuclear antigen 1 expression by increasing sensitivity of mitochondria apoptosis of nasopharyngeal carcinoma cells

Journal of Experimental & Clinical Cancer Research, 2018
Background Epstein-Barr virus (EBV) is widely found in nasopharyngeal carcinoma (NPC) tissue and associated with poor prognosis of patients. EBV nuclear antigen 1 (EBNA1) is expressed in all NPC tumors and plays multiple biological roles in both virus ...

Carbon‐Based Flexible Electrode for Efficient Electrochemical Generation of Reactive Chlorine Species in Tumor Therapy

Advanced Healthcare Materials, EarlyView.
A flexible electrode loaded with a carbon nanowire network (CC@C‐NWN) is developed for electrochemically generating reactive chlorine species (RCS) from abundant chloride ions in body fluids for tumor therapy. CC@C‐NWN enhances chlorine evolution, inducing redox dysregulation and synergistic apoptosis‐ferroptosis in tumor cells.
