Multiplex RT-PCR Assay for Detection of Common Fusion Transcripts in Acute Lymphoblastic Leukemia and Chronic Myeloid Leukemia Cases.
BACKGROUND Acute lymphoblastic leukemia (ALL) is a heterogeneous disease which requires a risk-stratified approach for appropriate treatment. Specific chromosomal translocations within leukemic blasts are important prognostic factors that allow identification of relevant subgroups. In this study, we developed a multiplex RT-PCR assay for detection of the 4 most frequent translocations in ALL (B...
متن کاملMultiplex fluorescent RT-PCR to quantify leukemic fusion transcripts.
The detection of chimeric transcripts derived from aberrant chromosomal fusion events provides an exceptionally valuable toolfor the diagnosis of leukemia. We have developed a simple, inexpensive, reproducible, and automated method to quantify RT-PCR products. Our approach utilizesfluorescent PCRfor the co-ampification of the specific fusion transcript with an internal control (HPRT). We have a...
متن کاملMultiplex PCR of bcr-abl fusion transcripts in Philadelphia positive acute lymphoblastic leukemia.
We describe a multiplex PCR assay for the detection of bcr-abl fusion mRNA in Philadelphia chromosome positive acute lymphoblastic leukemia (Ph + ALL). The assay provides a quick method for screening p190 (e1:a2) and p210 (b2:a2 or b3:a2) bcr-abl mRNAs simultaneously. The assay proves to be highly sensitive with detection of as little as one positive bcr-abl-expressing cell in a background of 1...
متن کاملMultiplex reverse transcription-PCR screening for EML4-ALK fusion transcripts.
PURPOSE EML4-ALK is a fusion-type protein tyrosine kinase that is generated by inv(2)(p21p23) in the genome of non-small cell lung cancer (NSCLC). To allow sensitive detection of EML4-ALK fusion transcripts, we have now developed a multiplex reverse transcription-PCR (RT-PCR) system that captures all in-frame fusions between the two genes. EXPERIMENTAL DESIGN Primers were designed to detect a...
متن کاملFrequency of BCR-ABL Fusion Transcripts in Iranian Azeri Turkish patients with Chronic Myeloid Leukemia
Background: The Philadelphia chromosome (Ph) characterized by t (9; 22) (q34; q11.2) is a reciprocal translocation giving rise to a chimeric BCR-ABL fusion gene. Incidence of Ph chromosome is over 98% in Patients with Chronic Myeloid Leukemia (CML) and around 20% in acute lymphoblastic leukemia (ALL). The finding of this fusion gene is essential for diagnosis of CML by detection of various fusi...
