Summary
Genetic susceptibility to radiation-induced thyroid cancer was investigated. Variants in CDH2, NFATc2, ENOSF1/THYS, RPA3, and MGMT genes are associated with differentiated thyroid cancer risk.
Area of Science:
- Genetics
- Oncology
- Radiation Biology
Background:
- Diagnostic procedures increasingly involve radiation, necessitating understanding of genetic factors influencing thyroid cancer risk.
- Genetic susceptibility plays a role in developing radiation-induced thyroid cancer.
Purpose of the Study:
- To investigate genetic susceptibility to radiation-induced differentiated thyroid cancer (DTC).
- To identify specific gene variants associated with DTC risk following radiation exposure.
Main Methods:
- Two case-control studies in France analyzed self-declared diagnostic radiology records.
- Thyroid radiation doses were estimated for 1,071 DTC cases and 1,188 controls.
- Genotyping focused on 5,817 single nucleotide polymorphisms (SNPs) in 571 DNA damage response and repair genes.
Main Results:
- A 1.02 odds ratio (OR) per milli-Gray (mGy) for thyroid radiation dose was observed.
- Significant associations were found between DTC and variants in CHD2, NFATc2, ENOSF1/THYS, and RPA3.
- An interaction between an MGMT variant and thyroid radiation dose was significant.
Conclusions:
- Variants in CDH2, NFATc2, ENOSF1/THYS, RPA3, and MGMT are implicated in differentiated thyroid cancer risk.
- CDH2, NFATc2, ENOSF1/THYS, and RPA3 variants show a novel association with DTC risk.

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Other Unique Bacteria

Magnetic bacteria exhibit a directed movement called magnetotaxis, driven by structures called magnetosomes. These magnetosomes consist of chains of magnetic particles made of either magnetite (Fe₃O₄) or greigite (Fe₃S₄) and are organized in a linear conformation by a protein scaffold within invaginations of the cell membrane. The bacteria align along the north–south magnetic field lines, much like a compass needle. They are typically microaerophilic or anaerobic...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
197
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
