TRAIL, a Mighty Apoptosis Inducer

Youngleem Kim, Dai-Wu Seol

Abstract

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a membrane-bound cytokine molecule that belongs to the family of tumor necrosis factor (TNF). TRAIL has been shown to be a potent apoptosis inducer in a wide variety of cancer cells in vitro and to limit tumor growth efficiently in vivo without damaging normal tissues. These features have focused considerable attention on TRAIL as a potential therapeutic agent to treat human cancers. Recent data also suggest the implication of TRAIL in a natural defense mechanism since its abrogation results in certain autoimmune disorders. This review will summarize recent progress in TRAIL research, including understanding of apoptotic signaling, regulation of TRAIL action, and possible therapeutic applications.

COVER PICTURE
Chronic obstructive pulmonary disease (COPD) is marked by airspace enlargement (emphysema) and small airway fibrosis, leading to airflow obstruction and eventual respiratory failure. Shown is a microphotograph of hematoxylin and eosin (H&E)-stained histological sections of the enlarged alveoli as an indicator of emphysema. Piao et al. (pp. 558-572) demonstrate that recombinant human hyaluronan and proteoglycan link protein 1 (rhHAPLN1) significantly reduces the extended airspaces of the emphysematous alveoli by increasing the levels of TGF-β receptor I and SIRT1/6, as a previously unrecognized mechanism in human alveolar epithelial cells, and consequently mitigates COPD.
