18 Questions
What was the primary objective of this study?
To explore the radiosensitizing effect of TRPV1 channel inhibitors in cancer cells
What was the outcome of using TRPV1 channel inhibitors in cancer cells?
They suppressed DNA damage response and enhanced radiation-induced reproductive death
What type of cells were used in the study?
A549 human lung adenocarcinoma cells and B16 mouse melanoma cells
What was the purpose of irradiating the cells with γ-rays?
To induce DNA damage response
What was the dose of γ-rays used in the study?
2.0 Gy
What was the duration of incubation after irradiation?
30 min
What is the primary goal of using radiosensitizers in cancer therapy?
To reduce damage to adjacent normal tissues during radiotherapy
What is the target of radiosensitizers in cancer therapy?
DNA damage repair systems
What type of nanoparticles are being researched as radiosensitizers to improve the efficacy of cancer radiotherapy?
Gold nanoparticles
What is the primary issue with using fractionated-dose irradiation in cancer treatment?
DNA repair during inter-fraction intervals
What is the role of the TRPV1 channel in response to DNA damage after γ-irradiation?
It is involved in the early responses to DNA damage
Why were TRPV1 channel inhibitors hypothesized to have a radiosensitizing effect?
Because they can block the repair of radiation-induced cell damage
What is the function of the TRPV1 channel in cells?
A non-selective cation channel and pain receptor
What is the potential effect of TRPV1 channel inhibitors on cancer cells?
They increase the susceptibility of cancer cells to γ-irradiation
What is the role of ATM in the early response to radiation-induced DNA damage?
Inducing phosphorylation of H2AX at DNA damage sites
What type of cancer cells are often targeted by radiosensitizers?
Radioresistant hypoxic cancer cells
What is the purpose of using radiosensitizers in cancer treatment?
To increase the effectiveness of radiation therapy
What is the result of hypoxia in solid cancer cells?
Decreased susceptibility to radiation
