Amplified fragment length polymorphism (AFLP-PCR or AFLP) is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by Pieter Vos, [ 1 ] AFLP uses restriction enzymes to digest genomic DNA , followed by ligation of adaptors to the sticky ends of the restriction ...
A biomarker may be used to see how well the body responds to a treatment for a disease or condition. Also called molecular marker and signature molecule." [18] In cancer research and medicine, biomarkers are used in three primary ways: [19] To help diagnose conditions, as in the case of identifying early stage cancers (diagnostic)
A tumor marker is a biomarker that can be used to indicate the presence of cancer or the behavior of cancers (measure progression or response to therapy). They can be found in bodily fluids or tissue. Markers can help with assessing prognosis, surveilling patients after surgical removal of tumors, and even predicting drug-response and monitor ...
Cancer is a disease with excessive molecular causes and constant evolution. There's also heterogeneity of disease even in an individual. Molecular studies of cancer have proved the significance of driver mutations in the growth and metastasis of tumors. [46] Many technologies for detection of sequence variations have been developed for cancer ...
Amplified fragment length polymorphism is a PCR-based DNA fingerprinting technique. DNA is first digested with endonucleases. The restriction fragments are then ligated together. [31] A molecular marker is then generated when specific fragments are selected for amplification. AFLP markers are run alongside a DNA marker on a gel.
Kompetitive allele specific PCR (KASP) is a homogenous, fluorescence-based genotyping variant of polymerase chain reaction. It is based on allele-specific oligo extension and fluorescence resonance energy transfer for signal generation.
In biomedical contexts, a biomarker, or biological marker, is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated using blood, urine, or soft tissues [1] to examine normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. [2]
Prognostic markers are biomarkers used to measure the progress of a disease in the patient sample. [1] Prognostic markers are useful to stratify the patients into groups, guiding towards precise medicine discovery. The widely used prognostic markers in cancers include stage, size, grade, node and metastasis. In addition to these common markers ...
