Insights

Oncoviruses mimic human protein interfaces to drive cancer by targeting key host proteins. This computational study reveals viral strategies for subverting immunity and offers new avenues for drug design.

Area of Science:

  • Virology
  • Oncology
  • Computational Biology

Background:

  • Oncoviruses subvert host immunity and pathways for proliferation, but precise mechanisms remain unclear.
  • Understanding oncovirus-host interactions is crucial for cancer research and therapeutic development.

Purpose of the Study:

  • To investigate the role of oncovirus mimicry of human protein interfaces in cancer development.
  • To explore oncovirus strategies for targeting host proteins and inducing cellular transformation.

Main Methods:

  • Utilized a novel interface-based host-microbe interaction (HMI) prediction method.
  • Employed computational approaches to model 3D structural HMIs and analyze protein targeting.

Main Results:

  • Oncoviruses mimic human protein binding surfaces to target key network proteins, leading to cancer hallmarks.
  • Identified specific and shared host protein targets across different oncoviruses, suggesting common infection strategies.
  • Estimated a 25% false discovery rate based on oncovirus-targeted human protein tissue expression.

Conclusions:

  • Interface mimicry is a pivotal strategy employed by oncoviruses to drive cancer.
  • Computational HMI modeling provides a tractable approach to elucidate pathogenesis and aid drug design.
  • Findings offer insights into oncovirus virulence mechanisms and potential therapeutic targets.

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Cancer-Critical Genes II: Tumor Suppressor Genes

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
