Insights

Poxviruses like vaccinia and myxoma are promising candidates for oncolytic virotherapy, selectively destroying cancer cells with a strong safety profile. Combining these oncolytic viruses with traditional treatments may enhance efficacy for incurable cancers.

Area of Science:

  • Oncology
  • Virology
  • Biotechnology

Background:

  • Standard cancer treatments often fail to cure, necessitating novel therapeutic approaches.
  • Oncolytic virotherapy utilizes replication-competent viruses to target and eliminate cancer cells, sparing healthy tissues.
  • Poxviruses, including vaccinia and myxoma, exhibit significant potential as oncolytic agents due to their inherent properties.

Purpose of the Study:

  • To review poxviruses being developed for oncolytic virotherapy.
  • To summarize clinical and preclinical findings of poxvirus-based oncolytic virotherapy.
  • To explore the synergistic effects of combining poxvirus oncolytic virotherapy with conventional cancer treatments.

Main Methods:

  • Review of existing clinical and preclinical studies on poxviruses for oncolytic virotherapy.
  • Analysis of safety and efficacy data from trials involving vaccinia and myxoma viruses.
  • Examination of research on combination therapies involving poxvirus oncolytic virotherapy.

Main Results:

  • Poxviruses demonstrate remarkable safety in clinical and preclinical oncolytic virotherapy studies.
  • Candidate poxviruses show potential for treating various types of currently incurable cancers.
  • Combination of poxvirus oncolytic virotherapy with conventional therapies indicates superior efficacy.

Conclusions:

  • Poxviruses are a viable and safe platform for oncolytic virotherapy.
  • Further development of poxvirus-based therapies holds promise for challenging cancers.
  • Combination strategies may significantly improve treatment outcomes in oncology.

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 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...

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
