Summary
This study introduces genome system theory, proposing that chromosome sets organize genes and genomic topology regulates gene expression. This "karyotype coding" explains "system inheritance" beyond traditional gene-based inheritance.
Area of Science:
- Genomics
- Molecular Biology
- Genetics
Background:
- The traditional gene-centric view of inheritance is being challenged by new genomic data.
- Chromosomal variations are increasingly recognized for their role in diseases, but their genomic basis is poorly understood.
Purpose of the Study:
- To introduce and discuss the concept of karyotype or chromosomal coding within the framework of genome system theory.
- To explore the rationale for new genomic inheritance models.
- To present the significance and evidence of chromosomal coding in biological systems.
Main Methods:
- This mini-review discusses the concept of karyotype coding.
- It examines the hypothesis, model, and predictions of chromosomal coding.
- It reviews evidence supporting chromosomal coding's role in maintaining and altering bio-systems.
Main Results:
- Genome system theory offers an alternative framework to gene-centric inheritance.
- Karyotype coding posits that chromosome sets act as gene organizers, with genomic topology regulating gene expression.
- This system inheritance encompasses gene content, karyotype, and 3D genomic topology.
Conclusions:
- Chromosomal coding provides a new conceptual framework for understanding genome organization and information.
- It highlights the importance of "system inheritance" alongside "parts inheritance" (genes).
- This perspective is crucial for future genomic and evolutionary studies.

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

02:31Synteny and Evolution
3.7K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

02:54Evolutionary Relationships through Genome Comparisons
6.8K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

01:33Cancer-Critical Genes I: Proto-oncogenes
11.0K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

02:21Cancers Originate from Somatic Mutations in a Single Cell
14.5K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
