TranscriptomicsPorphyromonas gingivalis 33277 wild-type vs Fur orthologue Har isogenic mutant ECR455
Porphyromonas gingivalis is a major pathogen associated with the microbial biofilm-mediated disease chronic periodontitis. P. gingivalis has an obligate requirement for iron and protoporphyrin IX which it satisfies by transporting heme and iron liberated from the human host. The level of cellular ir...

TranscriptomicsChange in gene expression in Chlamydomonas reinhardtii upon heat shock
This was an accompanying experiment. Previously, the expression of genes hsp70A and hsp70B had been established as being tetrapyrrole-dependent (Kropat et al., 1997, 2000). Since both are well-known heat-shock proteins, we performed a one-step heat shock treatment by shifting the temperatures from 2...

TranscriptomicsCharacterization of protoporphytin IX effects on X-ray irradiation in Hela cells in vitro
Hela cells were used to evaluate the protoporphytin IX (PpIX) effects on X-ray irradiation. Treatment conditions were (1) control group (untreated cells); (2) cells treated with 1 μg /ml PpIX for 6 hours; (3) cells irradiated with 3Gy X-rays; (4) cells treated with 1 μg /ml PpIX for 6 hours prior ...
