The IGF system plays a major role in growth, development and maintenance of homeostasis in normal cells and also contributes towards proliferation of malignant cells. Any disruption in the IGF system has its implications on growth retardation, atherosclerosis, insulin resistance and cancer. Imbalances in the IGF axis are known to contribute towards the progression of breast cancer. Due to the ubiquitous nature of the components of the IGF system, targeting specific members of the axis has gained attention over the past decades. The most elaborately investigated component as a therapeutic target in the system is the IGF-IR and studies have been pursued to inhibit IGF-IR by the administration of monoclonal antibodies and tyrosine kinase inhibitors. Very recently, a novel cell death receptor that binds specifically to IGFBP-3 was identified. It has also been shown that the IGFBP-3/IGFBP-3 receptor may be impaired in breast and prostate cancer. In this review, we present the mechanisms used to target the IGF system in various diseased states, emphasizing on breast cancer. We further discuss currently available therapeutic approaches and summarize the latest patents published in the field of IGF-I/IGF-IR and IGFBP-3/IGFBP-3R systems.

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.

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
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...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
