Analysis of the DNA damage response in living cells [PDF]

, 2007
DNA lesions arising from environmental and endogenous sources induce various cellular responses including cell cycle arrest, DNA repair and apoptosis. Although detailed insights into the biochemical mechanisms and composition of DNA repair pathways have ...

Quantifying DNA strand breaks from targeted alpha emitters 225Ac and 227Th via Geant4-DNA: implications for RBE and cell survival

EJNMMI Physics
Background Targeted alpha therapy (TAT) utilizing high-LET alpha particles from radionuclides like 225Ac and 227Th shows promise in cancer treatment due to their ability to induce dense, localized DNA damage.

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Cutaneous Squamous Cell Carcinoma (SCC) and the DNA Damage Response:pATM Expression Patterns in Pre-Malignant and Malignant Keratinocyte Skin Lesions [PDF]

, 2011
Recent evidence suggests that an initial barrier to the emergence of tumours is a DNA damage response that evokes a counter-response which arrests the growth of, or eliminates, damaged cells.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Clustered DNA damages induced in isolated DNA and in human cells by low doses of ionizing radiation [PDF]

Proceedings of the National Academy of Sciences, 2000
Clustered DNA damages—two or more closely spaced damages (strand breaks, abasic sites, or oxidized bases) on opposing strands—are suspects as critical lesions producing lethal and mutagenic effects of ionizing radiation. However, as a result of the lack of methods for measuring damage clusters induced by ionizing radiation in genomic DNA, neither the ...

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Regulation of nucleotide excision repair by UV-DDB: prioritization of damage recognition to internucleosomal DNA [PDF]

, 2011
How tightly packed chromatin is thoroughly inspected for DNA damage is one of the fundamental unanswered questions in biology. In particular, the effective excision of carcinogenic lesions caused by the ultraviolet (UV) radiation of sunlight depends on ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.
