Targeted Cancer Therapies

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.

Tumor Immunotherapy

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.

Examination of safety and efficacy data.

Main Results:

Betulinic acid demonstrated selective cytotoxicity against specific tumor types and infectious agents.
In vivo studies in mice bearing melanoma xenografts showed a favorable safety margin.
Induces apoptosis in a p53- and CD95-independent manner, likely via a mitochondrial pathway.

Conclusions:

Betulinic acid exhibits significant anti-cancer and anti-infective properties.
Its unique mechanism of action, potentially involving mitochondrial pathways, suggests efficacy in drug-resistant cancers.
Further research is warranted to elucidate precise molecular targets and optimize therapeutic applications.
