Insights

Genetic variations in pattern recognition receptors (PRRs) and their signaling pathways may influence cancer risk and progression. This review analyzes polymorphisms linked to various cancers, especially those caused by infectious agents.

Area of Science:

  • Immunology
  • Oncology
  • Genetics

Background:

  • Pattern recognition receptors (PRRs), including Toll-like receptors, NOD-like receptors, C-type lectin receptors, and RIG-I-like receptors, are crucial for detecting infectious agents.
  • These receptors initiate immune responses against pathogens, some of which are carcinogenic.
  • Genetic variations in PRRs and their signaling pathways can impact immune function and influence cancer development.

Purpose of the Study:

  • To review the association between inherited structural variations in PRRs and their signaling pathways with cancer risk and progression.
  • To analyze relevant malignancies, gene polymorphisms, and future research directions in this field.
  • To propose a strategy for selecting polymorphisms for further oncogenomic investigation.

Main Methods:

  • Literature review and analysis of existing studies on PRR gene polymorphisms and cancer.
  • Examination of associations between specific polymorphisms and various cancer types.
  • Synthesis of findings from basic research and epidemiological studies.

Main Results:

  • Polymorphisms in genes encoding PRRs and their signaling proteins are potentially associated with nearly all cancer types.
  • Strong associations are observed in cancers with a significant infectious agent component, such as gastric, colorectal, liver, cervical, and nasopharyngeal carcinomas.
  • The review identifies key gene polymorphisms and discusses their implications for cancer risk and progression.

Conclusions:

  • Genetic variations in PRRs and associated signaling pathways represent a significant factor in cancer development and progression.
  • Further oncogenomic investigation of selected PRR polymorphisms, guided by integrated basic and epidemiological data, is warranted.
  • Understanding these genetic links can lead to novel strategies for cancer prevention and treatment.

Mismatch Repair01:20

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

Cancers Originate from Somatic Mutations in a Single Cell

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...
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 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...
