Genome-wide RNAi Screening to Identify Host Factors That Modulate Oncolytic Virus Therapy
Published on: April 3, 2018
Abstract:
Retroviruses have long been fascinating to biologists because of their capacity to induce neoplasms in various animals. The transformation of the cells by the viruses was due to their oncogene-products. The viral oncogenes were thought to be originated from DNA of normal cells by recombination events between retroviruses and cellular oncogenes. Recently, many cellular oncogenes were identified in human cancerous cells by the DNA transfection method, some of which were found to contain sequences related with already known viral oncogenes. On the other hand, the research on the relation between these oncogenes and chromosomal translocation associated with carcinogenesis is now in progress.
Insights
Retroviruses can cause cancer by integrating viral oncogenes into host DNA. Researchers are now exploring links between these oncogenes, cellular oncogenes, and chromosomal changes in human cancers.
Area of Science:
- Oncology
- Virology
- Molecular Biology
Context:
- Retroviruses are known for their ability to induce neoplasms (tumors) in animals.
- Viral oncogenes, responsible for cell transformation, are believed to arise from recombination between retroviruses and cellular oncogenes.
- Recent studies have identified cellular oncogenes in human cancers using DNA transfection, with some showing homology to known viral oncogenes.
Purpose:
- To investigate the origin and role of viral and cellular oncogenes in carcinogenesis.
- To explore the relationship between identified oncogenes and chromosomal translocations in cancer development.
Summary:
- This research focuses on retroviruses and their oncogenic potential, particularly the role of viral oncogenes derived from cellular DNA.
- The study highlights the identification of cellular oncogenes in human cancers, some related to viral oncogenes.
- Current research is examining the connection between these oncogenes and chromosomal translocations implicated in cancer.
Impact:
- Understanding the mechanisms of retroviral oncogenesis and the role of oncogenes in human cancers.
- Potential for identifying new diagnostic markers or therapeutic targets for cancer based on oncogene and chromosomal aberration research.
