Sensitization to the Lysosomal Cell Death Pathway upon Immortalization and Transformation (2004)

Fehrenbacher, Nicole, Gyrd-Hansen, Mads, Poulsen, Birgit, Felbor, Ute, Kallunki, Tuula, Boes, Marianne, ...

Tumorigenesis is associated with several changes that alter the cellular susceptibility to programmed cell death. Here, we show that immortalization and transformation sensitize cells in particular...

Caspase-independent cell death (2002)

Leist, Marcel, Jäättelä, Marja

Caspase-mediated apoptosis is the death program of choice in many developmental and physiologic settings. It would, however, be very dangerous for the organism to depend on a single protease family...

Burning up TNF toxicity for cancer therapy (2002)

Leist, Marcel, Jäättelä, Marja

The tumor-killing capacity and the systemic toxicity of the cytokine tumor necrosis factor (TNF) have appeared inseparable. Now a study shows that TNF loses its toxicity but still kills tumors in...

Eradication of Glioblastoma, and Breast and Colon Carcinoma Xenografts by Hsp70 Depletion (2002)

Nylandsted, Jesper, Wick, Wolfgang, Hirt, Ulrich A., Brand, Karsten, Rohde, Mikkel, Leist, Marcel, ...

Heat shock protein 70 (Hsp70) is an antiapoptotic chaperone protein highly expressed in human tumors. Here we demonstrate that locoregional application of adenovirus expressing antisense Hsp70 cDNA...

Cathepsin B Acts as a Dominant Execution Protease in Tumor Cell Apoptosis Induced by Tumor Necrosis Factor (2001)

Foghsgaard, Lasse, Wissing, Dorte, Mauch, Daniel, Boes, Marianne, Elling, Folmer, Leist, Marcel, ...

Death receptors can trigger cell demise dependent or independent of caspases. In WEHI-S fibrosarcoma cells, tumor necrosis factor (TNF) induced an increase in cytosolic cathepsin B activity followed...

Selective depletion of heat shock protein 70 (Hsp70) activates a tumor-specific death program that is independent of caspases and bypasses Bcl-2

Nylandsted, Jesper, Rohde, Mikkel, Brand, Karsten, Bastholm, Lone, Elling, Folmer, Jäättelä, Marja

Heat shock protein 70 is an antiapoptotic chaperone protein highly expressed in human breast tumors and tumor cell lines. Here, we demonstrate that the mere inhibition of its synthesis by adenoviral...

Involvement of caspase-dependent activation of cytosolic phospholipase A2 in tumor necrosis factor-induced apoptosis

Wissing, Dorte, Mouritzen, Helle, Egeblad, Mikala, Poirier, Guy G., Jäättelä, Marja

Tumor necrosis factor (TNF)-induced apoptosis is mediated by caspases, which are cysteine proteases related to interleukin 1β-converting enzyme. We report here that TNF-induced activation of...

Diarylurea Compounds Inhibit Caspase Activation by Preventing the Formation of the Active 700-Kilodalton Apoptosome Complex

Lademann, Ulrik, Cain, Kelvin, Gyrd-Hansen, Mads, Brown, David, Peters, Dan, Jäättelä, Marja

The release of mitochondrial proapoptotic proteins into the cytosol is the key event in apoptosis signaling, leading to the activation of caspases. Once in the cytosol, cytochrome c triggers the...

Hsp70–RAP46 interaction in downregulation of DNA binding by glucocorticoid receptor

Schneikert, Jean, Hübner, Susanne, Langer, Gernot, Petri, Thomas, Jäättelä, Marja, Reed, Jennifer, ...

Receptor-associating protein 46 (RAP46) is a cochaperone that regulates the transactivation function of several steroid receptors. It is transported into the nucleus by a liganded glucocorticoid...
