Inhibition of SIRT7 Overcomes Radioresistance in Pancreatic Neuroendocrine Tumors by Reactivating MEN1 Expression

open access: yesAdvanced Science, EarlyView.
Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

Deoxyribonucleic acid damage in Iranian veterans 25 years after wartime exposure to sulfur mustard [PDF]

open access: yes, 2013
• Background: More than 100,000 Iranian veterans and civilians still suffer from various long-term complications due to their exposure to sulfur mustard (SM) during the Iran–Iraq war in 1983–88. The aim of the study was to investigate DNA damage of SM in

Valosin-containing protein regulates the proteasome-mediated degradation of DNA-PKcs in glioma cells. [PDF]

open access: yes, 2013
DNA-dependent protein kinase (DNA-PK) has an important role in the repair of DNA damage and regulates the radiation sensitivity of glioblastoma cells. The VCP (valosine-containing protein), a chaperone protein that regulates ubiquitin-dependent protein ...

Macrophage Extracellular Traps in Immunity and Cancer

open access: yesAdvanced Science, EarlyView.
As a macrophage‐mediated innate defense mechanism, the dysregulated release of METs drives chronic inflammation and influences tumor progression. Furthermore, METs exhibit a functional duality within the tumor microenvironment, capable of both promoting and suppressing tumor development.

Consequences of simulated microgravity in neural stem cells: biological effects and metabolic response. [PDF]

open access: yes, 2015
Objective: Microgravity was often shown to cause cell damage and impair cell cycle in a variety of biological systems. Since the effects on the neural system were poorly investigated, we aimed to gain insight into how biological processes such as cell ...

The International Comet Assay Workshop [PDF]

open access: yesMutagenesis, 1998
The Comet (single cell gel electrophoresis) assay primarily measures DNA strand breakage in single cells (Singh et al., 1988). Briefly, cells are suspended in low melting point agarose on a microscope slide. The slides are put in lysing buffer to allow the DNA to unwind and then in electrophoresis buffer.
