Pronunciation: [bˌiːsˌiːˈɑː vˈiː ˈabə͡l ˈɒnkə͡ʊd͡ʒˌiːnz] (IPA)

The spelling of "bcr v abl Oncogenes" may seem daunting at first, but it can be easily broken down using the International Phonetic Alphabet (IPA) transcription. "Bcr" is pronounced as /biːsiːɑːr/, "v" is pronounced as /viː/, and "abl" is pronounced as /eɪbiːɛl/. Finally, "Oncogenes" is pronounced as /ɒŋkədʒiːnz/. Altogether, the term refers to a group of genes that, when mutated, can lead to the formation of cancerous tumors. Understanding the phonetic transcription can help to better comprehend the pronunciation and overall spelling of the term.

BCR V ABL ONCOGENES Meaning and Definition

1. BCR-ABL oncogenes are fusion genes that result from the rearrangement of genetic material between the BCR (breakpoint cluster region) and ABL (Abelson) genes. These oncogenes are a hallmark of chronic myeloid leukemia (CML) and a subset of acute lymphoblastic leukemia (ALL).

   The BCR-ABL fusion gene is formed as a result of a chromosomal translocation, wherein a piece of chromosome 9, which contains the ABL gene, fuses with a piece of chromosome 22, which contains the BCR gene. This translocation occurs as a result of errors in DNA repair mechanisms, leading to the formation of abnormal proteins with constitutive tyrosine kinase activity.

   The resulting BCR-ABL fusion protein has the ability to overly activate signaling pathways that regulate cellular growth and survival, leading to uncontrolled proliferation and resistance to apoptosis (programmed cell death). This uncontrolled cell growth and survival is the underlying cause of malignant transformation and the development of leukemia.

   The detection of BCR-ABL fusion genes is critical in the diagnosis and monitoring of CML and certain forms of ALL. Tests such as fluorescence in situ hybridization (FISH) and polymerase chain reaction (PCR) are commonly used to detect the presence of BCR-ABL fusion transcripts and monitor their levels over time.

   Targeted therapies, such as tyrosine kinase inhibitors (TKIs), have revolutionized the treatment of BCR-ABL-positive leukemias. These drugs specifically target the aberrant tyrosine kinase activity of the BCR-ABL fusion protein and have shown remarkable efficacy in inducing remission and prolonging survival in affected individuals.
