Insights

Picornaviruses are being explored as novel anticancer agents. These oncolytic viruses (OVs) selectively target and destroy cancer cells, offering a promising therapeutic approach.

Area of Science:

  • Virology
  • Oncology
  • Gene Therapy

Background:

  • Oncolytic viruses (OVs) represent a novel class of anticancer therapeutics.
  • Several viral families, including Picornaviridae, exhibit anticancer properties.
  • Picornaviruses are small, non-enveloped RNA viruses with potential for cancer treatment.

Purpose of the Study:

  • To review picornaviruses investigated for their anticancer potential.
  • To elucidate the mechanisms underlying the cancer-specific activity of picornaviruses.

Main Methods:

  • Literature review of studies on picornaviruses as anticancer agents.
  • Analysis of viral characteristics relevant to cancer therapy.
  • Examination of mechanisms of viral oncolysis and tumor specificity.

Main Results:

  • Picornaviruses demonstrate selective infection and lysis of cancer cells.
  • Advantages for cancer therapy include non-integration of genomes, absence of oncogenes, and ease of genetic manipulation.
  • Specific picornaviruses have been identified and studied for their therapeutic efficacy.

Conclusions:

  • Picornaviruses hold significant promise as oncolytic viruses for cancer treatment.
  • Their inherent biological properties contribute to their specificity and safety profile.
  • Further research into picornavirus mechanisms can optimize their use in oncology.

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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Gene Therapy00:59

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Group Therapy01:26

Group Therapy

Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Psychodynamic Therapy01:29

Psychodynamic Therapy

Psychodynamic therapies emphasize the exploration of unconscious processes and early childhood experiences as fundamental contributors to psychological difficulties. These therapies, deeply rooted in Freud's psychoanalytic theory, aim to uncover and resolve unconscious conflicts, granting individuals insights that promote emotional and behavioral healing. Contemporary psychodynamic approaches have evolved, integrating a broader range of influences and methodologies while still valuing the...

Humanistic Therapy01:24

Humanistic Therapy

Humanistic therapies emphasize personal growth, self-understanding, and the fulfillment of human potential. Rooted in the belief that individuals inherently strive toward self-actualization, these approaches encourage clients to explore their feelings and experiences in a supportive, nonjudgmental environment. Humanistic therapies differ from psychodynamic approaches by focusing on conscious experiences, present circumstances, and the potential for self-improvement rather than past conflicts...
