Insights

Replication-competent viruses, like reovirus, show promise in cancer therapy by selectively targeting tumor cells. These oncolytic viruses exploit cancer cells

Area of Science:

  • Oncology and Virology

Background:

  • Cancer therapy research is advancing through understanding tumorigenesis.
  • Targeted therapies like antibodies and inhibitors show clinical promise.
  • Oncolytic viruses represent a novel therapeutic strategy.

Purpose of the Study:

  • To explore the potential of replication-competent viruses as cancer therapeutics.
  • To highlight reovirus as a promising oncolytic virus for cancer treatment.

Main Methods:

  • Exploiting tumor-specific characteristics for targeted therapy development.
  • Utilizing reovirus, a naturally occurring benign virus, for cancer treatment.
  • Evaluating reovirus in pre-clinical studies and clinical trials.

Main Results:

  • Tumor cells are more susceptible to oncolytic viruses than normal cells due to impaired antiviral responses.
  • Reovirus has demonstrated the ability to effect tumor regression in animal models.
  • Reovirus shows a lack of toxicity and signs of efficacy in clinical trials.

Conclusions:

  • Replication-competent viruses, particularly reovirus, offer a novel and exciting approach to cancer therapy.
  • Reovirus demonstrates significant promise as a potential cancer therapeutic agent with a favorable safety profile.

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...

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...

Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
Cancer Therapies02:49

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
