Is Intravenous and Oral Topotecan in Small-Cell Lung Cancer Truly Equal? A Case Report

open access: yesCase Reports in Oncology
Introduction: Treatment with topotecan is standard-of-care therapy for relapsed small-cell lung cancer (SCLC). Both oral and intravenous administrations of topotecan have been extensively researched and are found to be equally effective with less adverse

Topoisomerase 1 Regulates Gene Expression in Neurons through Cleavage Complex-Dependent and -Independent Mechanisms. [PDF]

open access: yesPLoS ONE, 2016
Topoisomerase 1 (TOP1) inhibitors, including camptothecin and topotecan, covalently trap TOP1 on DNA, creating cleavage complexes (cc's) that must be resolved before gene transcription and DNA replication can proceed.
