Polymerase chain reaction (PCR) amplifies specific DNA from tissue sections, enabling analysis of genomic alterations and pathogen detection. This technique links morphology to molecular pathology, even in archival samples.

Area of Science:

  • Molecular Biology
  • Genetics
  • Pathology

Context:

  • Histological sections provide a link between disease morphology and molecular alterations.
  • Paraffin-embedded archival specimens are suitable for PCR analysis.
  • Minute biological samples are sufficient for sensitive molecular detection.

Purpose:

  • To analyze genomic alterations (mutations, deletions, translocations) in pathogenetic processes.
  • To detect heterologous nucleic acids (viral, bacterial) with high sensitivity.
  • To bridge the gap between morphological descriptions and molecular underpinnings of disease.

Summary:

  • Polymerase chain reaction (PCR) amplifies specific DNA sequences from tissue sections using Taq polymerase.
  • The method allows analysis of genomic alterations and detection of foreign nucleic acids.

  • It is applicable to paraffin-embedded archival material and requires minimal sample amounts.

    • Impact:

    • Enables molecular analysis of disease directly from histological sections.
    • Facilitates the study of gene mutations and expression in preneoplastic and neoplastic tissues.
    • Provides a sensitive tool for molecular pathology, complementing classical morphological analysis.
