Narrative review without systematic search methodology
PubMed 26223848 · doi:10.1128/MMBR.00006-15
What was done
This is a narrative review surveying methodological developments used to interrogate mammalian three-dimensional genome architecture. It reviews visual imaging approaches (such as fluorescence in situ hybridization [FISH]) and molecular chromosome conformation capture techniques (such as 3C and Hi-C), discussing their contributions to understanding nuclear folding and transcription regulation.
What was found
The abstract presents a qualitative overview of methodological evolution and biological principles rather than empirical findings; no quantitative numbers, sample sizes, or numerical results are reported.
Why it matters
It provides a consolidated conceptual overview of how complementary imaging and sequencing-based conformation capture techniques delineate chromosome topology across multiple genomic scales in mammalian cells.
Limits
As a narrative review, it lacks a systematic literature search protocol, quantitative data synthesis, or predefined inclusion and exclusion criteria. It presents no new primary empirical data.
