Summary
Gene therapy shows promise for cancer treatment by targeting oncogenes or enhancing anti-tumor immunity. While preclinical studies are positive, clinical trials are still evolving, with some showing promising results in later phases.
Area of Science:
- Oncology
- Molecular Biology
- Immunology
Context:
- Gene therapy is a promising approach for treating malignant diseases, including cancers.
- Research focuses on two main gene categories: oncogenes/oncosuppressors for direct tumor killing and immunoregulatory molecules to boost anti-tumor immunity.
Purpose:
- To review genes targeted for cancer therapy and current clinical trials.
- To provide a better understanding of the field of cancer gene therapy.
Summary:
- Gene therapy utilizes viral or unviral vectors to deliver therapeutic genes, aiming to directly eliminate tumors or enhance the host's immune response against cancer.
- Preclinical studies demonstrate anti-tumor efficacy, but overall clinical trial success has been limited, raising questions about its superiority over conventional treatments.
- Despite challenges, recent Phase II/III clinical trials show encouraging responses for specific targeted genes, suggesting potential advancements.
Impact:
- Highlights the ongoing development and challenges in clinical translation of cancer gene therapy.
- Provides insights into the diverse strategies and targeted genes being investigated for cancer treatment.
- Informs researchers and clinicians about the current status and future directions of gene therapy in oncology.

00:59Gene 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 inserted. The...

02:57Targeted 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.

02:56Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
01:30Cancer 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...
