Moan J, Bech O, Peng Q, Berg K
Tidsskr Nor Laegeforen . 1998 May; 118(8):1206-11. PMID: 9567698
5-aminolevulinic acid is an early intermediate product in the synthesis of heme. Some of the enzymes in the heme synthesis chain have altered activities in tumor tissue, so that application...

J Photochem Photobiol B . 1998 Jan; 41(1-2):136-44. PMID: 9440321
Different cell lines were given photodynamic treatment with 5-aminolaevulinic acid (ALA) and light. In addition, the iron chelator 1,2-diethyl-3-hydroxypyridin-4-one (CP94) was used. The porphyrin species produced was spectrofluorimetrically identified as...

Moan J, Bech O, Gaullier J, Stokke T, Steen H, Ma L, et al.
Int J Cancer . 1998 Jan; 75(1):134-9. PMID: 9426701
Human colon adenocarcinoma cells (WiDr) and Chinese hamster lung fibroblasts cells (V79) were incubated with different concentrations of 5-aminolevulinic acid (ALA), and the production of protoporphyrin IX (PpIX) was studied...

Bech O, Berg K, Moan J
Cancer Lett . 1997 Feb; 113(1-2):25-9. PMID: 9065797
Chinese hamster cells (V79) and human adenocarcinoma cells (WiDr) were incubated with 5-aminolevulinic acid (ALA) at different pH values and the rate of production of protoporphyrin IX (PpIX) was measured....

Int J Cancer . 1997 Jan; 70(1):90-7. PMID: 8985096
Protoporphyrin IX (Pp IX) is the main photosensitizer in photochemotherapy with 5-aminolevulinic acid (ALA). Pp IX is photolabile and the present work shows that 70-95% of Pp IX in cells...

Berg K, Anholt H, Bech O, Moan J
Br J Cancer . 1996 Sep; 74(5):688-97. PMID: 8795569
Human adenocarcinoma cells of the line WiDr and Chinese hamster lung fibroblasts of the line V79 were treated with 5-aminolaevulinic acid (5-ALA) and exposed to light. The effects of the...
