Molecular pathology is the future of pathology.
Overview
Molecular pathology can be divided as follows:
| Molecular pathology | |||||||||||||||||||
| Molecular | Cytogenetics | ||||||||||||||||||
Molecular
General:
- Very small changes.
Techniques:
- DNA sequencing - RT-PCR.
- RNA sequencing.
- Southern blot.
Tests
- Hereditary:
- Factor V.
- Factor II.
- Hemochromatosis.
- Malignant hyperthermia.
- Hereditary amyloidosis.
- Alpha thalassemia.
- Lymphoma.
- Follicular lymphoma vs. follicular hyperplasia (BCL2).
- T cell neoplasia.
- B cell neoplasia.
- PTLPD vs. rejection.
- HHV associated lymphomas.
- Leukemia.
- Carcinoma:
- Nasopharyngeal (EBV quantitation).
- HPV testing.
- Metastatic colorectal carinoma.
- Non small cell lung cancer.
- Papillary thyroid carcinoma.
- Other:
- Oligodendroglioma.
- Identity testing (15 STRs and amelogenin (XY) loci).
- Melanoma (KIT, BRAF).
- Synovial sarcoma.
- Myeloproliferative disorders.
- AML, mastocytosis, GIST.
Cytogenetics
General:
- Large changes (chromosomal).
- Maximum resolution 3-4 megabase pairs (3-4 million base pairs); may be less - dependent on band density.[1]
Techniques:
- ISH = in situ hybridization.
- FISH = fluorescent in situ hybridization.
- SISH = silver in situ hybridization.[2]

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,[3] yet the announcement is in pay-for-access journal (Nature Structual Biology).[4]
Wnt/beta-catenin pathway
Important in hepatoblastomas.[5]
