Cytogenetics and Cell Genetics
|January 1, 1986
Summary
Researchers mapped the polymorphic DNA probe D3S3 to chromosome 3p14. This genetic marker is near a fragile site, aiding the study of 3p aberrations in cancers.
Area of Science:
- Human Genetics
- Molecular Biology
- Cancer Research
Background:
- Chromosome 3 aberrations are implicated in various malignant diseases.
- Precise localization of polymorphic DNA markers is crucial for genetic studies.
- The short arm of chromosome 3 (3p) is frequently altered in cancers.
Purpose of the Study:
- To regionally assign the polymorphic DNA probe D3S3 on the human genome.
- To identify novel genetic markers for studying chromosome 3 abnormalities.
- To investigate the potential of D3S3 in cancer research.
Main Methods:
- Utilized molecular hybridization techniques.
- Employed a human chromosome 3/hamster somatic cell hybrid deletion panel.
- Performed regional mapping of the D3S3 probe.
Main Results:
- Successfully assigned the D3S3 probe to the 3p14 region of chromosome 3.
- This represents the first regional assignment of a polymorphic probe to chromosome 3p.
- D3S3 was found to be proximal to the chromosome 3 fragile site.
Conclusions:
- The D3S3 probe is a valuable genetic marker localized to chromosome 3p14.
- Its proximity to the fragile site suggests utility in characterizing 3p chromosomal aberrations.
- D3S3 can aid in understanding the genetic basis of various malignant diseases.

Labeling DNA Probes
DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Southern Blot
Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...

FISH - Fluorescent In-situ Hybridization
Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...
In-situ Hybridization
In situ hybridization (ISH) is a technique used to detect and localize specific DNA or RNA molecules in cells, tissue, or tissue sections using a labeled probe. The technique was first used in 1969 for the investigation of nucleic acids. It is currently an essential tool in scientific research and clinical settings, especially for diagnostic purposes.
