Insights

Virotherapy utilizes replication-competent viruses to target and destroy cancer cells. The measles virus (MV) Edmonston B strain shows potent, selective oncolytic activity against human tumors, offering a safe cancer treatment strategy.

Area of Science:

  • Oncology
  • Virology
  • Biotechnology

Background:

  • Cancer treatment is evolving with novel biological agents.
  • Virotherapy, using replication-competent viruses, is a promising strategy.
  • Molecular virology enables genetic engineering of viruses for targeted cancer therapy.

Purpose of the Study:

  • To review the development of replication-competent oncolytic measles virus (MV) for cancer therapy.
  • To highlight the potential of MV-Edm as a safe and effective anti-cancer agent.

Main Methods:

  • Utilizing molecular virology techniques to engineer viruses.
  • Investigating replication-competent attenuated Edmonston B measles vaccine strain (MV-Edm).
  • Assessing the oncolytic properties and tumor selectivity of MV-Edm.

Main Results:

  • MV-Edm demonstrates potent anti-tumor activity against various human tumors.
  • The virus selectively infects and replicates in tumor cells, causing cell death.
  • Extensive cell-to-cell fusion is induced by MV-Edm in tumor cells.

Conclusions:

  • Replication-competent oncolytic MV, specifically MV-Edm, is a safe and efficient therapeutic agent for cancer.
  • Further enhancements to MV vectors could improve tumor selectivity and oncolytic efficacy.
  • MV-based virotherapy represents a significant advancement in cancer treatment strategies.

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...

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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
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...
