Molecular Pathology is a branch
of pathology that focuses on the study of diseases at the molecular level. It
involves examining the molecular and genetic mechanisms that underlie disease
processes, using techniques from molecular biology, genetics, and biochemistry.
This field aims to improve disease diagnosis, prognosis, and treatment through
a detailed understanding of the molecular alterations that occur in various
conditions. Molecular pathology is the study of disease at the molecular level,
including the molecules found in tissues and organs. It involves analysing DNA,
RNA, and proteins in a disease state to investigate human disease processes.
For example, sophisticated tests like Next Generation Sequencing can be
performed on DNA or RNA from tissue or blood samples to reveal genetic changes.
These changes may be indicative of germline disorders or somatic neoplastic.
1. Key Concepts in Molecular Pathology
a. Molecular Mechanisms of Disease
Genetic Mutations: Molecular pathology examines genetic
mutations, such as point mutations, insertions, deletions, and chromosomal
rearrangements, that drive disease processes.
Epigenetic Changes: It also studies epigenetic modifications
(e.g., DNA methylation, histone modification) that affect gene expression
without altering the DNA sequence.
Gene Expression: Analysing changes in gene expression levels
through techniques such as quantitative PCR and RNA sequencing helps understand
how deregulated gene expression contributes to diseases.
b. Diagnostic Techniques
Polymerase Chain Reaction (PCR): PCR amplifies specific DNA
or RNA sequences to detect genetic mutations or pathogens.
Next-Generation Sequencing (NGS): NGS allows for
high-throughput sequencing of DNA or RNA, enabling comprehensive genetic
profiling and identification of mutations across the genome.
In Situ Hybridization: This technique detects specific
nucleic acid sequences within tissue sections, helping visualize gene
expression patterns and localization.
