Human GAL1 receptor mRNA has been detected in multiple cell and tissue samples including Bowes melanoma cells, brain, gastrointestinal tract (from esophagus to rectum), heart, prostate, and testes. Rat GAL1 mRNA was detected in olfactory regions, many hypothalamic nuclei (including supraoptic nucleus),...

Ponnazhagan and Kwon (1992) reported a putative tissue-specific ds-element (TE-1) located at-236 bp of the mouse tyrosinase promoter. They partially purified a TE-1 binding protein (approximately 49 kDa in size), but tissue specificity remains to be confirmed by a more detailed analysis. For the human tyrosinase promoter, Shibata et al. (1992) identified a 200-bp pigment cell-specific enhancer, located between -2.0 and -1.8 kb. A minimum core sequence of 39 bp was shown to be sufficient to confer the specific activity, although other regions (not identified so far) within the 200-bp fragment are required for more efficient expression in melanoma cells (Shibata et al., 1992). 

Another potential source of iron, at least for hepatocytes, is receptor-independent uptake of iron from transferrin. This appears to involve an iron uptake pathway from transferrin which is neither suppressed in hepatocytes by antibodies to TfR (Trinder et at, 1988), nor by transfection of HuH-7 hepatoma cells with transferrin receptor anti-sense cDNA (Trinder etat, 1996). The same pathway may also be utilized for iron uptake from isolated transferrin N-lobe, which is not recognized by the receptor (Thorstensen et at, 1995). The possible role of TfR2 in this process remains to be established, as does the physiological importance of this pathway in intact liver. Human melanoma cells (Richardson and Baker, 1994) and Chinese hamster cells lacking transferrin receptors but transfected with melanotransferrin (Kennard et at, 1995) use another pathway for transferrin iron uptake, independent of the transferrin receptor, but utilizing iron transfer from transferrin or simple iron chelates to membrane-anchored melanotransferrin, and from there onwards into the cellular interior.

The importance of superoxide-mediated damage to cancer cells was also demonstrated in the experiments with overexpressed mitochondrial MnSOD. Hirose et al. [186] showed that the overexpression of mitochondrial MnSOD enhanced the survival of human melanoma cells exposed to cytokines IL-1 and TNF-a, anticancer antibiotics doxorubicin and mitomycin C, and y-irradiation. Similarly, Motoori et al. [187] found that overexpression of MnSOD reduced the levels of reactive oxygen species in mitochondria, the intracellular production of 4-hydroxy-2-nonenal, and prevented radiation-induced cell death in human hepatocellular... 

Inverse Relationship between Protease Inhibitors and Metastatic Ability. All proteases, apart from possibly CD, appear to be controlled by endogenous inhibitors. In theory, therefore, the ability of malignant cells to produce metastasis could depend not only on the levels of the specific protease, but also on the concentration of relevant endogenous inhibitors. Thus, the presence of high levels of protease inhibitors might inhibit metastasis, while low levels of inhibitors might enhance metastasis. An inverse relationship between a number of specific inhibitors and metastatic potential has now been shown. Some examples of this type of relationship include TIMP-1 in Swiss 3T3 cells (K4), cysteine protease inhibitors in mouse melanoma cells (R6), and an alpha-1-proteinase inhibitor in rat mammary carcinomas (N2). Furthermore, a newly described serine protease inhibitor, known as maspin, was found to be expressed less frequently in advanced human breast cancers compared with early cancers (Z2). 

Recently, a number of factors have been described that appear to be primarily motility factors (G3). These include scatter factor, a peptide produced by fibroblasts autocrine motility factor (AMF), a peptide originally purified from human melanoma cells and migration-stimulating factor (MSF), a peptide synthesized by embryo and certain tumor-associated fibroblasts. While both AMF...

Alteplase Alteplase is a drag that activates human tissue plasminogen (t-PA). It is a glycoprotein of molecular mass 68,000 that is synthesized by vascular endothelial cells. t-PA cells were first isolated from cultured human melanoma cells [56-58], but currently a genetically recombined form of rt-PA is genetically engineered.
