Genomic Instability and Cancer [PDF]
Journal of Carcinogenesis & Mutagenesis, 2014 Genomic instability is a characteristic of most cancer cells. It is an increased tendency of genome alteration during cell division. Cancer frequently results from damage to multiple genes controlling cell division and tumor suppressors. It is known that genomic integrity is closely monitored by several surveillance mechanisms, DNA damage checkpoint ...

Molecular Oncology, EarlyView.Detection of extrachromosomal circular DNA (eccDNA) in plasma samples from EGFR‐mutated non‐small cell lung cancer patients. Plasma was collected before and during treatment with the EGFR‐tyrosine kinase inhibitor osimertinib. Plasma eccDNA was detected in all cancer samples, and the presence of the EGFR gene on eccDNA serves as a potential biomarker ...

Molecular Oncology, EarlyView.Clinical trials on PARP inhibitors in urothelial carcinoma (UC) showed limited efficacy and a lack of predictive biomarkers. We propose SLFN5, SLFN11, and OAS1 as UC‐specific response predictors. We suggest Talazoparib as the better PARP inhibitor for UC than Olaparib.

MicroRNAs, Genomic Instability and Cancer [PDF]
International Journal of Molecular Sciences, 2014 MicroRNAs (miRNAs) are small non-coding RNA transcripts approximately 20 nucleotides in length that regulate expression of protein-coding genes via complementary binding mechanisms. The last decade has seen an exponential increase of publications on miRNAs, ranging from every aspect of basic cancer biology to diagnostic and therapeutic explorations ...

Molecular Oncology, EarlyView.HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

Drug Targeting of Genomic Instability in Multiple Myeloma
Frontiers in Genetics, 2020 Genomic instability can be observed at both chromosomal and chromatin levels. Instability at the macro level includes centrosome abnormalities (CA) resulting in numerical as well as structural chromosomal changes, whereas instability at the micro level ...

Effect of chemotherapy on passenger mutations in metastatic colorectal cancer
Molecular Oncology, EarlyView.Changes in passenger mutation load and predicted immunotherapy response after chemotherapy treatment. Tumor cells rich with passenger mutations have increased sensitivity to chemotherapy. Correlation of passenger mutations with neoantigen load suggests highly mutated clones promote a more effective response to immunotherapy, and therefore, first‐line ...

TRAIP/RNF206 is required for recruitment of RAP80 to sites of DNA damage
Nature Communications, 2016 Recruiting DNA damage repair factors to the sites of DNA damage is critical for the maintenance of genome integrity. Here the authors identify that the TRAF-interacting protein (TRAIP/RNF206) is required for normal recruitment of RAP80 to DNA lesions and

Genome instability: McClintock revisited [PDF]
Current Biology, 2001 Recent studies in yeast have shed light on the molecular mechanisms by which telomere dysfunction leads to chromosome fusions. Furthermore, examination of the consequences of telomerase loss in mice suggests that only a few critically short telomeres may be sufficient to promote genomic instability.
