Blue Light Aminolevulinic Acid Photodynamic Therapy Did Not Induce Detectable CPD or 6–4PP Photolesions in Human Dermal Fibroblasts

Journal of Biophotonics, Volume 19, Issue 8, August 2026.
This study demonstrates that combination BL and 5‐ALA PDT does not induce detectable levels of CPD or 6–4PP photolesions in human dermal fibroblasts in vitro. Our findings contribute to the lesion‐specific genotoxic safety profile of blue light photodynamic therapy, an established research topic.ABSTRACTPhotodynamic therapy (PDT) is an established ...

Isothiocyanates as Ferroptosis Inducers to Promote Cancer Cell Death

Phytotherapy Research, Volume 40, Issue 8, Page 5119-5131, August 2026.
ABSTRACT Cancer remains a leading cause of global mortality, with the therapeutic efficacy of anticancer drugs often hampered by late diagnosis and the development of chemotherapy resistance. Ferroptosis is an iron‐dependent form of regulated non‐apoptotic cell death driven by lipid peroxidation.

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, Volume 49, Issue 8, Page 5401-5420, August 2026.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Automated HPLC method for determining zinc protoporphyrin ix and protoporphyrin ix in erythrocytes of workers exposed to lead.

Sangyo Igaku, 1988
We developed an automated HPLC method for determining erythrocyte protoporphyrin. After a single extraction with N,N-dimethylformamide (DMF), zinc protoporphyrin IX (ZP) and protoporphyrin IX (PP) were separated by the column packed with a new type of reversed phase silica (capcell type) within 5 min. The column life was markedly extended to facilitate

Oxygen and Conformation Dependent Protein Oxidation and Aggregation by Porphyrins in Hepatocytes and Light-Exposed CellsSummary

Cellular and Molecular Gastroenterology and Hepatology, 2019
Background & Aims: Porphyrias are caused by porphyrin accumulation resulting from defects in the heme biosynthetic pathway that typically lead to photosensitivity and possible end-stage liver disease with an increased risk of hepatocellular carcinoma ...
