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.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Tumor irradiation induced immunogenic response: the impact of DNA damage induction and misrepair

Radiation Oncology
Focal tumor irradiation, a cornerstone of cancer therapy, has been increasingly recognized for its capacity to provoke systemic immunogenic responses that extend beyond localized tumor control.

Clonal somatic copy number altered driver events inform drug sensitivity in high-grade serous ovarian cancer

Nature Communications, 2022
Chromosomal instability is a major challenge to patient stratification and targeted drug development for high-grade serous ovarian carcinoma. Here we show that identification of clonal somatic copy number alterations in frequently amplified cancer genes ...

RADIATION-INDUCED GENOMIC INSTABILITY [PDF]

Health Physics, 2011
Radiation induced genomic instability can be observed in the progeny of irradiated cells multiple generations after irradiation of parental cells. The phenotype is well established both in vivo (Morgan 2003) and in vitro (Morgan 2003), and may be critical in radiation carcinogenesis (Little 2000, Huang et al. 2003).

Genomic instability and mouse microRNAs [PDF]

Toxicology Mechanisms and Methods, 2011
Tumor progression is the continual selection of variant subpopulations of malignant cells that have acquired increasing levels of genetic instability (Nowell Science 1976, 194, 23-28). This instability is manifested as chromosomal aneuploidy or translocations, viral integration or somatic mutations that typically affect the expression of a gene ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

Molecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

SLC30 (ZnT) and SLC39 (ZIP) zinc transporter families: from gatekeepers of zinc homeostasis to promoters of tumorigenesis and targets for clinical therapy

Frontiers in Immunology
Zinc is a trace element that plays important functions in gene expression, enzymatic activity and cellular signaling. Cellular zinc homeostasis is tightly regulated by two solute carrier families: SLC30 (ZnT, zinc transporter) and SLC39 (ZIP, zrt- and ...
