Dipeptidyl peptidase II (DPP II) in normal rat lung was evaluated by the enzymes' ability to hydrolyze Lys-Ala or Lys-Pro derivatives of 4-methoxy-2-naphthylamine (MNA). For visualization of this activity, the liberated MNA was coupled with fast blue B for light

Metabolism studies on organized HaCaT keratinocyte cell sheets are reported. Cells were grown on porous membranes to form organized cell sheets of several cell layers, which were considered as a model of viable epidermis. Metabolism was studied by reflection kinetics
A new fluorometric assay for determining dipeptidyl peptidase IV (DPP IV; EC 3.4.14.5) was developed. The synthetic substrate glycyl-L-proline-4-methoxy-2-naphthylamide (20 mmol/L), Tris buffer (50 mmol/L, pH 8.3), and serum (20 microL) are mixed and incubated. The reaction is stopped with
The cysteine proteases cathepsin B and cathepsin L are very likely involved in invasive processes of normal and malignant cells, they become relevant for a number of diseases and are possibly prognostic markers for the outcome of human lung cancer.
The purpose was to investigate changes in neuropeptide Y (NPY) protein and dipeptidyl peptidase IV (DPP-IV) activity in the plasma and saliva in normally cycling women and women after menopause. We recruited 7 cycling women and 7 postmenopausal women for
