can you paraphrase this: Gene therapy, a transformative medical approach, involves modifying cellular genetic content to combat disease. Utilizing vectors, often viruses, a healthy gene replaces a defective one in a patient's cells. Despite its experimental status, gene therapy shows potential against malignancies, genetic disorders, and viral infections. Challenges include accurate gene control and vector-associated risks like insertional mutagenesis, which can disrupt host cell genes, possibly leading to cancer. The EIAV lentivirus vector study uncovers insertional mutagenesis' significance. Injected into mouse genomes, it induced genetic changes resulting in hepatocellular carcinoma (HCC), emphasizing the genotoxic risk of lentiviral vectors. Recovery methodologies, like LAM PCR, unravel genetic insights. The B-raf gene's involvement in the MAP kinase pathway suggests cancer links. This study examined EIAV-induced tumour DNA sequences, aligning with B-raf gene's sequence, underpinning cancer-associated cascades. Gene therapy holds transformative potential, providing solutions for existing health challenges.

The principle of flow cytometry is to measure the distribution and number of cells in a Suspension Medium. In flow cytometry, the Suspension Medium is filled with cells and passed through a series of filters that allow only the cells through. The number of cells that pass through the filters can be used to calculate the size of the sample. Flow cytometry is a more accurate technology than immunohistochemistry, but is less versatile.

Describe the principles of flow cytometry and its purpose and compare these with other technologies such as immunohistochemistry

Radiation-induced chromosomal aberrations are the result of damage to the cells' DNA, which can cause missing or added genetic material, as well as broken chromosomes. This damage can occur naturally as a result of exposure to ionizing radiation, but it can also be caused by the use of cancer-causing radiation therapy.

Explain the mechanisms behind radiation-induced chromosomal aberrations?

0 ▲

Radiation-induced chromosomal aberrations, or RICAs, are the most common type of cancer caused by radiation. They happen when the breaks in the chromosomes caused by the radiation cause DNA to copy incorrectly. This can lead to a change in the gene that is responsible for a particular cellular function.
