Persistent Telomere Damage Induces Bypass of Mitosis and Tetraploidy

Tetraploidization has been proposed as an intermediate step toward aneuploidy in human cancer but a general mechanism for the induction of tetraploidy during tumorigenesis is lacking. We report that tetraploidization occurs in p53-deficient cells experiencing a prolonged DNA damage signal due to persistent telomere dysfunction. Live-cell imaging revealed that these cells have an extended G2 due...

DNA-damage response during mitosis induces whole-chromosome missegregation.

UNLABELLED Many cancers display both structural (s-CIN) and numerical (w-CIN) chromosomal instabilities. Defective chromosome segregation during mitosis has been shown to cause DNA damage that induces structural rearrangements of chromosomes (s-CIN). In contrast, whether DNA damage can disrupt mitotic processes to generate whole chromosomal instability (w-CIN) is unknown. Here, we show that act...

Development of a robust DNA damage model including persistent telomere-associated damage with application to secondary cancer risk assessment

Mathematical modelling has been instrumental to understand kinetics of radiation-induced DNA damage repair and associated secondary cancer risk. The widely accepted two-lesion kinetic (TLK) model assumes two kinds of double strand breaks, simple and complex ones, with different repair rates. Recently, persistent DNA damage associated with telomeres was reported as a new kind of DNA damage. We t...

Thymoquinone Induces Telomere Shortening, DNA Damage and Apoptosis in Human Glioblastoma Cells

BACKGROUND A major concern of cancer chemotherapy is the side effects caused by the non-specific targeting of both normal and cancerous cells by therapeutic drugs. Much emphasis has been placed on discovering new compounds that target tumour cells more efficiently and selectively with minimal toxic effects on normal cells. METHODOLOGY/PRINCIPAL FINDINGS The cytotoxic effect of thymoquinone, a...

G-quadruplex ligand SYUIQ-5 induces autophagy by telomere damage and TRF2 delocalization in cancer cells.

Agents stabilizing G-quadruplexes have the potential to destroy the functional structure of telomere and could therefore act as antitumor agents. We previously reported that SYUIQ-5 could stabilize G-quadruplex, induce senescence, and inhibit c-myc gene promoter activity. In this study, we showed that SYUIQ-5 inhibited proliferation of CNE2 and HeLa cancer cells, triggered a rapid and potent te...
