Genome-wide profiling of uncapped mRNA [PDF]
, 2012 Gene transcripts are under extensive posttranscriptional regulation, including the regulation of their stability. A major route for mRNA degradation produces uncapped mRNAs, which can be generated by decapping enzymes, endonucleases, and small RNAs ...

Genome Stability Requires p53 [PDF]
Cold Spring Harbor Perspectives in Medicine, 2016 It is now clear that functional p53 is critical to protect the genome from alterations that lead to tumorigenesis. However, with the myriad of cellular stresses and pathways linked to p53 activation, much remains unknown about how p53 maintains genome stability and the proteins involved. The current understanding of the multiple ways p53 contributes to

Genome stability versus transcript diversity [PDF]
DNA Repair, 2016 Our genome is protected from the introduction of mutations by high fidelity replication and an extensive network of DNA damage response and repair mechanisms. However, the expression of our genome, via RNA and protein synthesis, allows for more diversity in translating genetic information.

ARID1A mutation and genomic stability [PDF]
Molecular & Cellular Oncology, 2020 We have recently discovered that AT-rich interactive domain-containing protein 1A (ARID1A) protects telomere cohesion through regulation of the cohesin subunit stromal antigen 1 (STAG1). ARID1A inactivation results in mitotic defects and negatively selects gross chromosomal aberrations, resulting in preservation of genomic stability in ARID1A-mutated ...

Nature Communications, 2018 Chromosome instability is associated with cancer formation. Here the authors identify in cultured human cancer cells a non-canonical DNA bridge breakage pathway leading to chromosome missegregation and rearrangements triggered by sister DNA ...

Nature Communications, 2016 Werner syndrome is a progeroid disease characterised by genetic instability due to mutations to the WRN helicase/exonuclease. Here the authors define a novel Ku binding motif (KBM) and show that two such motifs facilitate the involvement of WRN in DNA ...

Immune Checkpoints in Viral Infections
Viruses, 2020 As evidence has mounted that virus-infected cells, such as cancer cells, negatively regulate the function of T-cells via immune checkpoints, it has become increasingly clear that viral infections similarly exploit immune checkpoints as an immune system ...

Genomic stability of Self-inactivating Rabies [PDF]
eLife, 2020 Abstract Transsynaptic viral vectors provide means to gain genetic access to neurons based on synaptic connectivity and are essential tools for the dissection of neural circuit function. Among them, the retrograde monosynaptic ΔG-Rabies has been widely used in neuroscience research.

Genomic stability and tumorigenesis
Seminars in Cancer Biology, 2005 Cancer research needs to explain the observed incidence of cancer. Many factors determine this process, including: the number of susceptible cells in the tissue of origin; the number of normal cell divisions through which susceptible cells pass in normal development and turnover; the number of cell divisions during tumorigenesis; the selective ...
