Methylation-dependent loss of RIP3 expression in cancer represses programmed necrosis in response to chemotherapeutics
Receptor-interacting protein kinase-3 (RIP3 or RIPK3) is an essential part of the cellular machinery that executes “programmed” or “regulated” necrosis. Here we show that programmed necrosis is… Expand
Apoptosis and autophagy: regulatory connections between two supposedly different processes
- A. Thorburn
- Biology, Medicine
Apoptosis and autophagy are genetically-regulated, evolutionarily-conserved processes that regulate cell fate. Both apoptosis and autophagy are important in development and normal physiology and in a… Expand
Autophagy in cancer: good, bad, or both?
Autophagy has been recognized as an important cellular process for at least 50 years; however, it is only with the recent identification of key regulators of autophagy (Atg genes) that we have begun… Expand
Phosphorylation of FADD at serine 194 by CKIalpha regulates its nonapoptotic activities.

FADD is essential for death receptor (DR)-induced apoptosis. However, it is also critical for cell cycle progression and proliferation, activities that are regulated by phosphorylation of its… Expand
STAT3-mediated autophagy dependence identifies subtypes of breast cancer where autophagy inhibition can be efficacious.
Autophagy is a protein and organelle degradation pathway that is involved in diverse diseases, including cancer. Recent evidence suggests that autophagy is a cell survival mechanism in tumor cells… Expand
Autophagy and metastasis: another double-edged sword.
In order to metastasize, tumor cells must adapt to untoward, stressful microenvironments as they disseminate into the systemic circulation and colonize distant organ sites. Autophagy, a tightly… Expand
Autophagy and apoptosis: what is the connection?
The therapeutic potential of autophagy for the treatment cancer and other diseases is beset by paradoxes stemming from the complexity of the interactions between the apoptotic and autophagic… Expand
Six1 overexpression in ovarian carcinoma causes resistance to TRAIL-mediated apoptosis and is associated with poor survival.
Tumorigenesis can arise from inappropriate activation of developmental genes in mature tissues. Here, we show that the developmental regulator Six1 is overexpressed in ovarian carcinoma cell lines… Expand
Hedgehog signaling alters reliance on EGF receptor signaling and mediates anti-EGFR therapeutic resistance in head and neck cancer.
The EGF receptor (EGFR)-directed monoclonal antibody cetuximab is the only targeted therapy approved for the treatment of squamous cell carcinoma of the head and neck (HNSCC) but is only effective in… Expand
Selective inactivation of a Fas-associated death domain protein (FADD)-dependent apoptosis and autophagy pathway in immortal epithelial cells.

Although evasion of apoptosis is thought to be required for the development of cancer, it is unclear which cell death pathways are evaded. We previously identified a novel epithelial cell death… Expand
