Abstract

Human cancers frequently arise from exposure to chemicals, although radiation, oxidation, and genetic factors play critical roles as well. DNA damage by these agents in a cell is an important first step in the process of carcinogenesis. DNA repair processes have evolved to repair these damages. However, the replication of damaged DNA may occur frequently prior to repair, resulting in gene mutations and the generation of altered proteins. Mutations in an oncogene, a tumor-suppressor gene, or a gene that controls the cell cycle give rise to a clonal cell population with an advantage in proliferation. The complex process of carcinogenesis includes many such events, but has been generally considered to be comprised of the three main stages known as initiation, promotion, and progression, which ultimately give rise to the induction of human cancer. The articles published in this book entitled “Chemically-Induced DNA Damage, Mutagenesis, and Cancer” provide an overview on the topic of the “consequence of DNA damage” in the context of human cancer with their challenges and highlights.

Abstract

The conditions for DNA replication are not ideal, owing to endogenous and exogenous replication stresses that lead to arrest of the replication fork. Arrested forks are among the most serious threats to genomic integrity because they can break or rearrange, leading to genomic instability, which is a hallmark of cancers and aging-related disorders. This title, “DNA Replication Controls”, presents series of new reviews and original research articles, providing a comprehensive guide to theoretical advancements in the field of DNA replication research in both prokaryotic and eukaryotic systems. The topics include DNA polymerases and helicases; replication initiation; replication timing; replication-associated DNA repair; and replication of difficult-to-replicate genomic regions, including telomeres, centromeres and highly-transcribed regions. This title also provides recent advancements in studies of cellular processes that are coordinated with DNA replication and how defects in the DNA replication program result in genetic disorders, including cancer. Written by leading experts in DNA replication regulation, this book will be an important resource for a wide variety of audiences, including junior graduate students and established investigators who have interests in DNA replication and genome maintenance mechanisms.

Abstract

This Special Issue of International Journal of Molecular Sciences (IJMS) is dedicated to the mechanisms mediated at the molecular and cellular levels in response to adverse genomic perturbations and DNA replication stress. The relevant proteins and processes play paramount roles in nucleic acid transactions to maintain genomic stability and cellular homeostasis. A total of 18 articles are presented which encompass a broad range of highly relevant topics in genome biology. These include replication fork dynamics, DNA repair processes, DNA damage signaling and cell cycle control, cancer biology, epigenetics, cellular senescence, neurodegeneration, and aging. As Guest Editor for this IJMS Special Issue, I am very pleased to offer this collection of riveting articles centered on the theme of DNA replication stress. The blend of articles builds upon a theme that DNA damage has profound consequences for genomic stability and cellular homeostasis that affect tissue function, disease, cancer, and aging at multiple levels and through unique mechanisms. I thank the authors for their excellent contributions, which provide new insight into this fascinating and highly relevant area of genome biology.
