WebCTCF is a nuclear protein initially discovered for its role in enhancer-promoter insulation. It has been shown to play a role in genome architecture and in fact, its DNA binding sites … WebThe chromatin in mitotic cells was found to be ~2.8 times more sensitive to radiation-induced DNA single-strand breakage than the chromatin of interphase cells. Conclusions: The alpha-inactivation coefficient of mitotic HT-29 cells was ~30 times larger than that of interphase cells.
Ionizing Radiation - Health Effects Occupational Safety …
Webterm radiosensitivity describes how likely the cell is to be damaged by radiation. Cancer cells tend to divide quickly and grow out of control. Radiation therapy kills cancer cells … WebMay 14, 2024 · For biologists, the most significant forms of radiation are light, heat, and ionizing radiation. Ionizing radiation can penetrate cells and create ions in the cell contents. These, in turn, can cause permanent alterations in DNA (i.e., mutations). Ionizing radiation includes X rays, gamma rays, neutrons, electrons ("beta" particles), and alpha ... barbacena 5

WebSep 30, 2024 · The radiation you get from x-ray, CT, and nuclear imaging is ionizing radiation — high-energy wavelengths or particles that penetrate tissue to reveal the body's internal organs and structures. Ionizing radiation can damage DNA, and although your cells repair most of the damage, they sometimes do the job imperfectly, leaving small areas of ... WebMar 23, 2024 · Ionizing radiation could affect either the whole body (somatic damage) and/or eggs and sperm (genetic damage). Figure 5.4. 1: Radiation can harm biological systems by damaging the DNA of cells. If this damage is not properly repaired, the cells may divide in an uncontrolled manner and cause cancer. Much of the threat from radiation is … WebJun 21, 2024 · Gold nanoparticles (AuNP) can increase the efficacy of radiation therapy by sensitising tumor cells to radiation damage. When used in combination with radiation, AuNPs enhance the rate of cell killing; hence, they may be of great value in radiotherapy. This study assessed the effects of radiation and AuNPs on mitochondrial reactive oxygen … barbacena a muriae
