Lack of prognostic significance of survivin, survivin-deltaEx3, survivin-2B, galectin-3, bag-1, bax-alpha and MRP-1 mRNAs in breast cancer.

The expression of transcripts for anti-apoptotic (survivin, survivin-deltaEx3, survivin-2B, galectin-3, bag-1 and bcl-2) and pro-apoptotic (bax-alpha) genes, and for multiple drug resistance related protein-1 (MRP-1) gene were investigated, using RT-PCR, in 106 breast tumour biopsies. Normal breast tissue was also analysed for comparative purposes. Overall, survivin, survivin-deltaEx3, survivin-2B, bcl-2, bag-1, galectin-3, bax-alpha and MRP-1 mRNAs were detected in 68, 54.

Galectin-3 expression alters adhesion, motility and invasion in a lung cell line (DLKP), in vitro.

Background: Galectin-3, a beta-galactosidase-binding protein, is involved in regulating many physiological and pathological cellular processes. The significance of galectin-3 in human lung and nasal carcinoma cells has not yet been elucidated.

Materials And Methods: Using RT-PCR and Western blotting techniques, the constitutive level of galectin-3 in the human non-small cell lung carcinoma cell line, DLKP, was investigated.
