The mean value of alpha 1-AT (+/- SEM) in cases with cancer of the pancreas was 486 (+/- 18) mg/100 ml, and it was significantly higher than the corresponding mean value in controls, which was 434 (+/- 13) mg/100 ml (p approximately 0.02).
Our results suggest that enhanced expression of EGF receptor in human pancreatic cancer can be associated with either structural or numerical alterations of chromosome 7.
One of the antibodies, CM1, recognises p53 in formalin-fixed, paraffin-embedded archival material and using this reagent we found immunodetectable p53 in 28 of 124 (23%) pancreatic cancers.
Well- to moderately-differentiated SW1990 and CAPAN-2 human pancreatic cancer cells were found to produce more high-Mr glycoprotein (HMG) than less-differentiated MIA PaCa-2 and PANC-1 cells.
These results indicate that the AC inhibitor in the pancreatic cancer extract is histone H1b or H1d and histones H2A, H2B and H3 also have an AC inhibitory activity.

Overexpression of the epidermal growth factor receptor in human pancreatic cancer is associated with concomitant increases in the levels of epidermal growth factor and transforming growth factor alpha.
These findings suggest that EGF and TGF-alpha may participate in the regulation of normal pancreatic exocrine function, and that overexpression of the EGF receptor and its two principal ligands may contribute to the pathophysiological processes that occur in human pancreatic cancer.
