Cancer-Critical Genes II: Tumor Suppressor Genes01:05

Cancer-Critical Genes II: Tumor Suppressor Genes

9.3K
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...

Genomics

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...

Mouse Models of Cancer Study

6.3K
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers 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...

Area of Science:

  • Genomics
  • Bioinformatics
  • Cancer Research

Background:

  • Understanding cancer requires integrative multi-omics data analysis, as single-dimensional approaches are insufficient.
  • Previous work introduced DriverDB for identifying cancer driver genes and mutations using bioinformatics algorithms.

Purpose of the Study:

  • To update DriverDB to DriverDBv3, enhancing its capability to interpret complex cancer omics information with data visualization.
  • To incorporate computational tools for defining copy number variation (CNV) and methylation drivers, offering deeper insights into molecular dysregulation.
  • To introduce new features (CNV, Methylation, Survival, miRNA) and a 'Survival Analysis' function for comprehensive exploration of gene relationships and co-occurring events.

Main Methods:

  • Incorporation of computational tools for CNV and methylation driver identification.
  • Addition of CNV, Methylation, Survival, and miRNA data exploration modules.
  • Redesign of the web interface with interactive figures and a Summary panel for multi-omics visualization.
  • Implementation of a 'Survival Analysis' function for customized analysis of gene co-occurrence and expression in patient groups.

Main Results:

  • DriverDBv3 provides concise data visualization for complex cancer omics information.
  • New features allow exploration of relationships between CNV, methylation, survival, and miRNA data.
  • The 'Survival Analysis' tool enables investigation of co-occurring events based on mutation status or expression.
  • An updated web interface and summary panel offer concise multi-omics feature visualization.

Conclusions:

  • DriverDBv3 improves the study of integrative cancer omics data by identifying driver genes.
  • The database contributes to a more comprehensive understanding of cancer biology through multi-omics integration.
  • Enhanced data visualization and analysis tools facilitate deeper insights into cancer molecular mechanisms.
