Molecular pathology is the future of pathology.
Overview
Molecular pathology can be divided as follows:
| Molecular pathology | |||||||||||||||||||
| Molecular techniques | Cytogenetics | ||||||||||||||||||
Molecular
General
- Very small changes - submicroscopic.
- Sequence data.
Techniques
- DNA sequencing.
- Real time-PCR, AKA real time-quantitative PCR (RQ-PCR).
- RNA sequencing.
- May be examined after reverse transcription (RNA -> DNA), i.e. RT-PCR.
- Southern blot.
- Analysis of proteins.
- Amplification-refractory mutation system (ARMS):[1]
- Technique for finding a (specific) single base change.
- The (PCR) primers are designed bind to the mutated sequence.
- If the mutation is present a PCR product is seen.
- If the mutation is absent no PCR product is seen.
- The (PCR) primers are designed bind to the mutated sequence.
- Technique for finding a (specific) single base change.
Specific tests
A list of tests are found in the Molecular pathology tests article.
DNA & RNA extraction
Cytogenetics
Main article: Cytogenetics
This deals with karyotyping and ISH.
Other garbage
World protein databank
I can't help think it is ironic that the protein databank goal is to maintain a free and publicly available archive,[4] yet the announcement is in pay-for-access journal (Nature Structual Biology).[5]
Wnt/beta-catenin pathway
Important in hepatoblastomas.[6]
