TUCAN/CARDINAL/CARD8 and apoptosis resistance in non-small cell lung cancer cells

BMC Cancer, 2006
Background Activation of caspase-9 in response to treatment with cytotoxic drugs is inhibited in NSCLC cells, which may contribute to the clinical resistance to chemotherapy shown in this type of tumor. The aim of the present study was to investigate the

Tumor‐Targeted Exosome‐Based Heavy Atom‐Free Nanosensitizers With Long‐Lived Excited States for Safe and Effective Sono‐Photodynamic Therapy of Solid Tumors

Advanced Healthcare Materials, EarlyView.
Engineered exosome‐based heavy atom‐free nanosensitizers are developed for safe and targeted sono‐photodynamic therapy of solid tumors. The IR820‐TPE‐loaded, biotin‐conjugated exosomes (IR820‐TPE@B‐Exo) demonstrate significant promise for NIR fluorescence imaging‐guided sono‐photodynamic cancer therapy.

A Complex between Atg7 and Caspase-9

Journal of Biological Chemistry, 2013
Background: Several cross-talk mechanisms between autophagy and apoptosis have been identified, where the same protein plays a central role in the opposing processes. Results: This study identified a novel cross-talk mechanism involving an Atg7·caspase-9

Nonlinear regulation of commitment to apoptosis by simultaneous inhibition of Bcl-2 and XIAP in leukemia and lymphoma cells [PDF]

Apoptosis 16:619-26 (2011), 2011
Apoptosis is a complex pathway regulated by the concerted action of multiple pro- and anti-apoptotic molecules. The intrinsic (mitochondrial) pathway of apoptosis is governed up-stream of mitochondria, by the family of Bcl-2 proteins, and down-stream of mitochondria, by low-probability events, such as apoptosome formation, and by feedback circuits ...

Proteolytic Processing of the Caspase-9 Zymogen Is Required for Apoptosome-mediated Activation of Caspase-9*

Journal of Biological Chemistry, 2013
Background: Proteolytic processing is involved in apoptosome-mediated caspase-9 activation, but its role is unknown. Results: Processed caspase-9 has much higher activity than its unprocessed zymogen in the presence of the apoptosome.

Protein‐Like Polymers Targeting Keap1/Nrf2 as Therapeutics for Myocardial Infarction

Advanced Materials, EarlyView.
We describe a Keap1 targeting protein‐like polymer (PLP) which activates Nrf2, an important cytoprotective transcription factor for relieving myocardial infarction‐induced oxidative stress. This PLP increases cell survival in vitro in multiple relevant cardiac cell types and elicits pro‐reparative responses, improving cardiac function in a preclinical ...
