BCL2 and small cell lung carcinoma: High expression of the cell adhesion protein β1-integrin and the anti-apoptotic protein Bcl-2 have both been associated with increased cell survival in in vitro models of SCLC (Sethi et al, 1999; Pardo et al, 2002; Sartorius and Krammer, 2002) but in vivo confirmation of an important role in patients with SCLC is sparse.
