Organoids: From Bench to Bedside Applications

MedComm, Volume 7, Issue 6, June 2026.
Organoids, as a groundbreaking biomedical research platform, utilize adult stem cells (ASCs), embryonic stem cells (ESCs), and induced pluripotent stem cells (iPSCs) as sources. By integrating specific growth and differentiation signals within an extracellular matrix (e.g., Matrigel), organoids guide cells to self‐assemble into three‐dimensional ...

Oxidative Stress and DNA Epigenetic Modifications in Cancer: Mechanisms and Targeted Therapeutics

MedComm – Oncology, Volume 5, Issue 2, June 2026.
Reactive oxygen species (ROS) modulate DNA methyltransferases (DNMTs), ten‐eleven translocation family proteins (TETs) and their cofactors, reshaping 5‐methylcytosine (5mC)/5‐hydroxymethylcytosine (5hmC)/5‐formylcytosine (5fC) landscapes and gene expression in cancer cells. In turn, epigenetic control of antioxidant and metabolic pathways feeds back on

DNA recognition, cleavage, and toxic metal ion interaction of an artificial zinc finger protein inside E. coli cells

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Zinc finger proteins are essential for the proper functioning of eukaryotic organisms, while their artificial variants can be used in cancer therapy or gene editing via their specific DNA recognition. Zn(II) binding is indispensable for the structural integrity of zinc fingers.

Socioeconomic and Demographic Factors in Genetic Testing Utilization Among Advanced Prostate Cancer Patients

The Prostate, Volume 86, Issue 8, Page 941-948, June 2026.
ABSTRACT Purpose Germline genetic testing in patients with advanced prostate cancer (PCa) is underutilized and hypothesized to be impacted by socioeconomic and demographic factors. This single institution, retrospective study assessed the association of income and social vulnerability with genetic referrals and testing.

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 6, Page 1245-1258, June 2026.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.
