DNA Replication Errors Drive Genome‐Wide Small Inverted Triplication Dynamics

open access: yesAdvanced Science, EarlyView.
This study provides insight into the dynamic equilibrium mechanism of a novel structural variant, small inverted triplication (SIT), which is generated by misalignment of the 3’ flap generated under DNA replication stress with palindromic sequence. Alternatively, the end sequence may fold back on itself to form an inverted fragment.

Microsatellite instability in Marek’s Disease Virus infected primary chicken embryo fibroblasts

open access: yesVirology Journal, 2012
Background Marek’s disease virus (MDV), an oncogenic α-herpes virus, causes a devastating disease in chickens characterized by development of lymphoblastoid tumors in multiple organs.

LINE-1 hypomethylation in cancer is highly variable and inversely correlated with microsatellite instability. [PDF]

open access: yesPLoS ONE, 2007
Alterations in DNA methylation in cancer include global hypomethylation and gene-specific hypermethylation. It is not clear whether these two epigenetic errors are mechanistically linked or occur independently.

Elevated neoantigen levels in tumors with somatic mutations in the HLA-A, HLA-B, HLA-C and B2M genes. [PDF]

open access: yes, 2019
BackgroundThe major histocompatibility complex class I (MHC-I) molecule is a protein complex that displays intracellular peptides to T cells, allowing the immune system to recognize and destroy infected or cancerous cells.

Mutations and amplification of oncogenes in endometrial cancer [PDF]

open access: yes, 1999
Alterations in oncogenes are critical steps in the development of endometrial cancer. To investigate the potential clinical relevance of the amplification of the oncogenes c-erbB2, c-myc, and int-2 and the mutation of K-ras in endometrial cancer, 112 ...

Testing tumors for microsatellite instability [PDF]

open access: yesEuropean Journal of Human Genetics, 1999
The methods for determining microsatellite instability in tumors are highly heterogeneous. Recently a 5-marker panel of microsatellites was suggested for this purpose. In this review attention is drawn to the fact that microsatellite instability can be assessed by analyzing tumor DNA with a single marker, BAT-26, and that normal tissue DNA from the ...

EEPD1 Inhibition Unleashes Antitumor Immunity in Colorectal Cancer by Activating the cGAS‐STING Pathway

open access: yesAdvanced Science, EarlyView.
In colorectal cancer, high expression of the DNA repair protein EEPD1 correlates with immune exclusion and poor prognosis. This study demonstrates that EEPD1 depletion induces genomic instability, leading to cytosolic DNA accumulation and subsequent activation of the cGAS‐STING‐type I interferon pathway. This cascade remodels the tumor microenvironment

Znaczenie mechanizmu naprawy DNA błędnie sparowanych zasad azotowych (MMR) w raku piersi

open access: yesMenopause Review, 2010
Background: Microsatellite instability (MSI) is due to defective DNA mismatch repair. Defects in DNA mismatch-repair (MMR) genes lead to replication errors revealed as instability in microsatellite markers.

Identification of a novel deletion mutant strain in Saccharomyces cerevisiae that results in a microsatellite instability phenotype [PDF]

open access: yesBioDiscovery, 2012
The DNA mismatch repair (MMR) pathway corrects specific types of DNA replication errors that affect microsatellites and thus is critical for maintaining genomic integrity.
