Metalloproteinases are zinc-dependent endopeptidases that function as primary effectors of tissue remodeling, cell-signaling, and many other roles. Their regulation is ferociously complex, and is exquisitely sensitive to their molecular milieu, making in vivo studies challenging. Phenanthroline (PhN) is an inexpensive, broad-spectrum inhibitor of metalloproteinases that functions by chelating t...
Dibenzo(a,e)fluoranthene (DBF), a highly carcinogenic polycyclic hydrocarbon without an apparent K-region, binds covalently to DNA, transfer RNA, and polyribonucleotides when incubated with hepatic microsomal frac tions under standard conditions. Optimal binding condi tions for [3H]DBF were established. Methylcholanthrene-pretreated mouse liver microsomes induced a higher level of binding of [ ...
The formation of polycyclic aromatic hydrocarbon-DNA adducts was studied in peripheral blood lymphocytes obtained from men with occupational and environmental exposure. Subjects included coke factory workers, residents from the vicinity of the cokery, and rural region inhabitants (16 individuals in each exposure group). Adducts were determined by immunohistochemical analysis using a polyclonal ...
