PHOTOCHEMISTRY AND PHOTOBIOLOGY OF PSORALENS [PDF]

open access: yesPhotochemistry and Photobiology, 1979
Abstract— The photochemistry and photobiology of psoralens have been rcvicwed on the basis of selected literature. In addition to the well establishcd photoaddition of psoralens to DNA. photoreac‐tions involving RNA. tRNA and proteins warrant further studies.

Psoralen induced cell cycle arrest by modulating Wnt/β-catenin pathway in breast cancer cells

open access: yesScientific Reports, 2018
Psoralen could inhibit the proliferation of human breast cancer cells, however, the molecular mechanism was unclear. We evaluated the anti-proliferative effects of psoralen by MTT, plate colony formation assay and cell cycle analysis in MCF-7 and MDA-MB ...

The human DNA glycosylases NEIL1 and NEIL3 excise psoralen-induced DNA-DNA cross-links in a four-stranded DNA structure [PDF]

open access: yes, 2017
Interstrand cross-links (ICLs) are highly cytotoxic DNA lesions that block DNA replication and transcription by preventing strand separation. Previously, we demonstrated that the bacterial and human DNA glycosylases Nei and NEIL1 excise unhooked ...

Replication-fork stalling and processing at a single psoralen interstrand crosslink in Xenopus egg extracts. [PDF]

open access: yesPLoS ONE, 2011
Interstrand crosslink (ICL)-inducing agents block the separation of the two DNA strands. They prevent transcription and replication and are used in clinics for the treatment of cancer and skin diseases. Here, we have introduced a single psoralen ICL at a

A gene expression profile-based approach to screen the occurrence and predisposed host characteristics of drug-induced liver injury: a case study of Psoralea corylifolia Linn

open access: yesFrontiers in Chemistry, 2023
Drug-induced liver injury (DILI) is one of the most common causes of a drug being withdrawn, and identifying the culprit drugs and the host factors at risk of causing DILI has become a current challenge. Recent studies have found that immune status plays
