DNA double-strand break end resection factors and WRN facilitate mitotic DNA synthesis in human cells

Nature Communications
Mitotic DNA synthesis (MiDAS) serves to complete the replication of genomic loci that are not fully replicated in S phase in response to replication stress.

53BP1 can limit sister-chromatid rupture and rearrangements driven by a distinct ultrafine DNA bridging-breakage process

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 ...

Iterative Correction of Hi-C Data Reveals Hallmarks of Chromosome Organization

Nature Methods, 2012
Extracting biologically meaningful information from chromosomal interactions obtained with genome-wide chromosome conformation capture (3C) analyses requires the elimination of systematic biases.

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

Molecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Depletion of ATP-citrate lyase (ATPCL) affects chromosome integrity without altering histone acetylation in Drosophila mitotic cells [PDF]

, 2019
The Citrate Lyase (ACL) is the main cytosolic enzyme that converts the citrate exported from mitochondria by the SLC25A1 carrier in Acetyl Coenzyme A (acetyl-CoA) and oxaloacetate.

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 ...

Efficient DNA-free genome editing of bread wheat using CRISPR/Cas9 ribonucleoprotein complexes

Nature Communications, 2017
Protocols for crop genome editing would ideally be quick, efficient and specific while avoiding integration of transgenes into the genome of edited plants. Here, Lianget al.

Securin Is Not Required for Chromosomal Stability in Human Cells [PDF]

, 2005
Abnormalities of chromosome number are frequently observed in cancers. The mechanisms regulating chromosome segregation in human cells are therefore of great interest.

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells

Molecular Oncology, EarlyView.
Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...

Molecular characterisation of human penile carcinoma and generation of paired epithelial primary cell lines

Molecular Oncology, EarlyView.
Generation of two normal and tumour (cancerous) paired human cell lines using an established tissue culture technique and their characterisation is described. Cell lines were characterised at cellular, protein, chromosome and gene expression levels and for HPV status.
