Fluorescence In Situ Hybridization (FISH)

Term: Fluorescence In Situ Hybridization (FISH)Definition: A molecular cytogenetic technique used to detect and locate the presence or absence of specific DNA sequences on chromosomes.Phonetic Pronunciation: (floo-RES-ens in SY-too hy-BRID-ih-ZAY-shun)Origin: The term originates from the Latin "fluo," meaning "to flow," and the Greek "phōs," meaning "light," indicating the use of fluorescent molecules. "In situ" is Latin for "in position," and "hybridization" comes from the Greek "hybris," meaning "hubris" or "excess," referring to the process of combining nucleic acid strands.Significance in Asbestos Context: FISH is significant in asbestos-related cases as it can be used to identify chromosomal abnormalities associated with asbestos-induced diseases, such as mesothelioma. This technique aids in the early detection and diagnosis of these conditions, which is crucial for legal claims and medical treatment.Example Sentence: The use of Fluorescence In Situ Hybridization (FISH) helped confirm the presence of chromosomal abnormalities in the patient's lung tissue, supporting the diagnosis of asbestos-related mesothelioma.Related Terms: Mesothelioma, Biomarker, Chromosomal Abnormality, Cytogenetics, DiagnosisNotes: - FISH is not a standalone diagnostic tool but is often used in conjunction with other diagnostic methods. - It can be used on various types of tissue samples, including those affected by asbestos exposure.
