Article Abstract
The human zinc finger protein 521 (ZNF521) is a co-transcriptional factor with multiple recognized regulatory functions in a range of normal, cancer and stem cell compartments. ZNF521 regulates proliferation, progression and CSC (cancer stem cell) compartments in human ovarian cancer (hOC), which is a very aggressive and late-diagnosed female tumor. Two other important regulators of hOC are the NRF2 and NOTCH signaling pathways. In the present paper, the mRNA and protein levels of ZNF521 were correlated with those of the NRF2-NOTCH signaling components in two different hOC cell lines and in a public dataset of 381 hOC patients. The data show that high levels of ZNF521 significantly increase NRF2-NOTCH signaling expression; conversely, the silencing of ZNF521 impairs NRF2-NOTCH signaling. This experimental work shows that, in hOC, different levels of ZNF521 modulate the NRF2-NOTCH signaling pathway and also influences hOC CSC properties.

The Nuclear factor erythroid 2-related factor 2 (NRF2) Neurogenic locus NOTCH homolog protein (NOTCH) crosstalk has emerged as a critical regulatory axis in the progression of solid cancers, especially lung, affecting tumor growth and resistance to therapy. NRF2 is a master transcription factor that orchestrates the cellular antioxidant response, while NOTCH signaling is involved in the cell-cell communication processes by influencing the patterns of gene expression and differentiation. Although frequently altered independently, genetic and epigenetic dysregulation of both NRF2 and NOTCH pathways often converge to deregulate oxidative stress responses and promote tumor cell survival.

Background: Retinopathy of Prematurity (ROP) is a proliferative retinal vascular disease occurring in the retina of premature infants and is the main cause of childhood blindness. Nowadays anti-VEGF and retinal photocoagulation are mainstream treatments for ROP, but they develop a variety of complications. Hydrogen (H) is widely considered as a useful neuroprotective and antioxidative therapeutic method for hypoxic-ischemic disease without toxic effects.

Chronic wounds fail to achieve complete closure and are an economic burden to healthcare systems due to the limited treatment options and constant medical attention. Chronic wounds are characterised by dysregulated signalling pathways. Research has focused on naturally derived compounds, stem-cell-based therapy, small molecule drugs, oligonucleotide delivery nanoparticles, exosomes and peptide-based platforms.

Article Synopsis
- The study investigates how PDA affects hepatocellular carcinoma SMMC-7721 cells, focusing on its mechanisms in vitro.
- PDA shows cytotoxic effects, leading to reduced cell growth and increased markers of stress (like ROS and calcium), while altering protein levels linked to apoptosis and cell cycle regulation.
- Results indicate that PDA not only disrupts specific signaling pathways (like Notch and Nrf2) but also normalizes various metabolite levels, suggesting its potential as a therapy for liver cancer.
