Transforming growth factor-beta (TGF-beta) superfamily regulates matrix metalloproteinases (MMP), which intrinsically regulate various cell behaviors leading to metastasis. We investigated the effect of TGF-beta(2) on MMP-2 regulation in human bladder carcinoma cell line 5637. Zymography, ELISA, and real-time polymerase chain reaction revealed that TGF-beta(2) stimulated MMP-2 production, but the transcription of its gene remained unchanged. Wortmannin could not inhibit MMP-2 secretion and activity and conversely the amount of the protein and its enzymatic activity were increased. These data suggest that TGF-beta(2) increased MMP-2 at the posttranscriptional level and this upregulation was independent of phosphatidylinositol 3-kinase signaling pathway.

D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

D053781 Transforming Growth Factor beta2 A TGF-beta subtype that was originally identified as a GLIOBLASTOMA-derived factor which inhibits the antigen-dependent growth of both helper and CYTOTOXIC T LYMPHOCYTES. It is synthesized as a precursor molecule that is cleaved to form mature TGF-beta2 and TGF-beta2 latency-associated peptide. The association of the cleavage products results in the formation a latent protein which must be activated to bind its receptor.
