Published: April 2021

Natural products are widely used as source for drugs development. An interesting example is represented by natural drugs developed against human topoisomerase IB, a ubiquitous enzyme involved in many cellular processes where several topological problems occur due the formation of supercoiled DNA. Human topoisomerase IB, involved in the solution of such problems relaxing the DNA cleaving and religating a single DNA strand, represents an important target in anticancer therapy. Several natural compounds inhibiting or poisoning this enzyme are under investigation as possible new drugs. This review summarizes the natural products that target human topoisomerase IB that may be used as the lead compounds to develop new anticancer drugs. Moreover, the natural compounds and their derivatives that are in clinical trial are also commented on.

Large-scale combination drug screens are generally considered intractable due to the immense number of possible combinations. Existing approaches use ad hoc fixed experimental designs then train machine learning models to impute unobserved combinations. Here we propose BATCHIE, an orthogonal approach that conducts experiments dynamically in batches.

Targeting TOP2A in Ovarian Cancer: Biological and Clinical Implications.

Curr Oncol

December 2024

Gynecology and Obstetrics 1U, Department of Surgical Sciences, University of Turin, 10126 Turin, Italy.

The enzyme topoisomerase II alpha (TOP2A) plays a critical role in DNA replication and cell proliferation, making it a promising target for cancer therapy. In epithelial ovarian cancer (EOC), TOP2A overexpression is associated with poor prognosis and resistance to conventional treatments. This review explores the biological functions of TOP2A in EOC and discusses its potential as a therapeutic target.

Sulforaphane (SFN), an isothiocyanate found in plants of the Brassicaceae family, possesses antioxidant, apoptosis-inducing, and radiosensitizing effects. As one of the mechanisms of cytotoxicity by SFN, SFN has been suggested to be involved in the induction of DNA damage and inhibition of DNA repair. Recently, we reported on the potency of SFN in inducing single-ended double-strand breaks (DSBs) that are caused by the collision of replication forks with single-strand breaks (SSBs).

Background: As a master immune system regulator, transforming growth factor β1 (TGF-β1) is closely linked to the complicated pathophysiology and development of systemic sclerosis (SSc), a multisystem fibrotic disease.

Objective: We aim to evaluate the transcriptional levels of TGF-β1 mRNA in PBMCs, assess the TGF-β1 serum levels of SSc patients, and compare them with those of healthy subjects.

Methods: PBMCs were isolated from whole blood of 50 SSc patients and in 30 healthy controls.
