Role of apoptotic and anti-apoptotic mechanisms in erythroblast differentiation [PDF]

, 2004
The present study focuses on deciphering the differentiation mechanisms of erythroid cells. In particular, the involvement of apoptotic mechanisms in erythroblast differentiation and enucleation was examined.

E2A selectively regulates TGF‐β–induced apoptosis in KRAS‐mutant non‐small cell lung cancer

Molecular Oncology, EarlyView.
Ability to induce apoptosis by TGF‐β is frequently lost in advanced lung adenocarcinoma despite intact TGF‐β signaling. We identify E2A as a mutant KRAS–dependent mediator of resistance to TGF‐β–induced apoptosis. TGF‐β induces E2A via SMAD3 in mutant KRAS cells, and E2A silencing restores apoptosis and enhances radiation response in cell lines ...

Effect of miR-21 on Apoptosis in Lung Cancer Cell Through Inhibiting the PI3K/ Akt/NF-κB Signaling Pathway in Vitro and in Vivo

Cellular Physiology and Biochemistry, 2018
Background/Aims: Lung cancer is one of the most common malignancies in the world. Apoptosis-stimulating protein of p53 (ASPP2), a tumorigenesis related protein, plays a critical role in the initiation and development of various types of cancers. However,

Caspase activation and apoptosis in response to proteasome inhibitors [PDF]

Cell Death & Differentiation, 2005
Several studies have indicated that proteasome inhibitors (PIs) are promising anticancer agents. We have discovered that PIs have the unique ability to activate effector caspases through a mitochondrial Bcl-2 inhibitable but caspase-9 independent pathway.

THE ROLE OF INFLAMMASOME AND CASPASE-1 IN REGULATING ADAPTIVE RESPONSE TO OXIDATIVE STRESS IN MOUSE HEPATOCYTES [PDF]

, 2013
In myeloid cells, oxidative stress can induce the activation of caspase-1 through canonical inflammasome signaling, which leads to the release of proinflammatory cytokines IL-1β/IL-18 and a potentially damaging inflammatory response.

Over-expression of MAP kinase phosphatase-2 enhances adhesion molecule expression and protects against apoptosis in human endothelial cells [PDF]

, 2010
In this study we used adenovirus infection to overexpress the dual specific phosphatase, MAP kinase phosphatase-2 (MKP-2), in human umbilical vein endothelial cells and examined inflammatory protein expression and apoptosis, two key features of ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Inhibitor specificity of recombinant and endogenous caspase-9 [PDF]

Biochemical Journal, 2002
Apoptosis triggered through the intrinsic pathway by radiation and anti-neoplastic drugs is initiated by the activation of caspase-9. To elucidate control mechanisms in this pathway we used a range of synthetic and natural reagents. The inhibitory potency of acetyl-Asp-Glu-Val-Asp-aldehyde ('Ac-DEVD-CHO'), benzyloxycarbonyl-Val-Ala-Asp ...

Caspase-9 and -3 colorimetric activity assay on WSU-FSCCL cells exposed to ApoG2 at indicated times and concentrations [PDF]

, 2011
50 μg of protein from cell lysates were incubated in triplicate with the corresponding substrates for caspase-9 (LEHD-pNA) caspase-3 (DEVD-pNA). Free pNA is released from the labeled synthetic substrate on cleavage by active caspase and analyzed (A and B)

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.
