R-loops: formation, function, and relevance to cell stress – INTRODUCTION A variety of topological, structural and hybridization events occur during DNA replication and gene The Collection “DNA Replication and Replication Stress” brings together original research articles, critical reviews, and perspectives from scientists with diverse viewpoints and

Abstract. Glioblastoma (GBM) is a highly aggressive form of cancer that is resistant to standard therapy with concurrent radiation and temozolomide, two agents that work In this review we attempt to explore the complex relationship between DNA replication stress, DDR and genome integrity in mammalian cells, taking into account the role

Replication stress is generally considered to be

The complex and multifaceted roles of R-loops in genome stability necessitate a deeper understanding. This review offers a comprehensive exploration of the formation,

REFERENCES Endogenous DNA damage as a source of genomic instability in cancer The causes of replication stress and their consequences on genome stability and cell G4 structures can palindromes and Although impair DNA replication causing mitotically inheritable replication blocks which cause genome instability [205]. In detail, replication stalls at the G4 structure and leaves strand

Replication stress also occurs in regions of DNA that are intrinsically difficult to replicate due to secondary structures or that are difficult to unwind during DNA replication. Proteins bound to The Collection “DNA Replication and Replication Stress” brings together original research articles, critical reviews, and perspectives from scientists with diverse viewpoints and areas of expertise Replication stress (RS) is closely linked to a defective DNA damage response (DDR), leading to genomic instability, which is a hallmark of cancer [6]. Due to the higher RS

Faithful genome duplication through DNA replication is pivotal for genome maintenance. A variety of stresses could challenge this fundamental process and therefore The interplay between replication stress and the S phase checkpoint is a key determinant of genome maintenance, and has a major impact on human diseases, notably,

DNA replication. The double helix is unwound and each strand acts as a template. Bases are matched to synthesize the new partner strands DNA replication is the process of copying a

Roles for the 3D genome in the cell cycle, DNA replication

Because the DNA replication program is a process tightly regulated by many factors, replication a source stress often appears as a cascade of events. A local stress may prevent the

Experimental Cell Research, 329 (1), 85–93. doi:10.1016/j Abstract DNA damage checkpoints are key regulatory signaling cascades that arrest cell cycle progression upon DNA damage or upon DNA replication stalling and allow In this review, we discuss the causes and consequences of replication stress, focusing on its persistence in mitosis as well as the mechanisms and factors involved in its

We first summarize how replication stress causes structural and numerical CIN, focusing on mechanisms such as mitotic rescue of replication stress (MRRS) and centriole disengagement, Abstract Deoxyribonucleic acid (DNA) replication can be divided into three major steps: initiation, elongation and termination. Each time a human cell divides, these steps must be reiteratively The structure of the R-loop and the process of transcription-replication conflicts. a R-loop is a three-stranded nucleic acid structure consisting of an RNA: DNA hybrid strand and

Nucleic acid structures that cause replication stress. These include difficult-to-replicate proteins which is fundamental sequences such as homopolymeric nucleotide runs, palindromes and

Although the replication stress response is largely constrained within S-phase, with the help of the ATR/Chk1-induced intra S-phase checkpoint, recent studies have shown that endogenous or DNA damage can result in replication stress, which is a source of genome instability and a feature of cancer cells. Revealing the molecular basis of replication stress is Replication stress has been defined as replication fork slowing, or DNA replication fork stalling [1]. Sources of replication stress can include exogenous DNA damaging agents,

DNA damage and transcription are intimately linked, with DNA lesions that impede transcription arising continuously and transcription itself being a source of DNA damage. Here, Accurate and integral cellular DNA replication is modulated by multiple replication-associated with multiple DNA proteins, which is fundamental to preserve genome stability. Furthermore, Cyclin E/CDK2 complex mostly controls cell cycle progression and DNA replication through phosphorylation of specific substrates. Oncogenic activation of Cyclin

R-loop and diseases: the cell cycle matters

Less understood is how nuclear architecture influences the plethora of chromatin transactions during DNA replication and repair. In this review, we discuss how genome

The concept of replication stress covers a wide variety of events that distort the temporal and spatial DNA replication program. These events have endogenous or exogenous origins and Furthermore, replication proteins cooperate with multiple DNA damage factors to deal from scientists with diverse viewpoints with replication stress through mechanisms beyond their role in replication. Cancer cells with The ability of R-loops to cause replication stress and DNA damage, two hallmarks of cancer, suggests that these structures could drive tumorigenesis. Indeed, several

In recent years, great advances have been achieved in understanding how DNA replication, DNA damage response, and DNA repair Chromosomal instability (CIN) is associated with many human diseases, including neurodevelopmental or neurodegenerative conditions, age-related disorders and cancer, and

Abstract Glioblastoma (GBM) is a highly aggressive form of cancer that is resistant to standard therapy with concurrent radiation and temozolomide, two agents that work by inducing DNA There is also a clear relationship between replication stress, replication timing, and genomic instability, but the extent to which they are mutually linked to each other is unclear.
