Insights

Targeting the insulin-like growth factor (IGF) pathway shows promise for overcoming breast cancer treatment resistance. However, current IGF-system modulators face significant limitations, requiring further development for effective breast cancer therapeutics.

Area of Science:

  • Oncology
  • Endocrinology
  • Molecular Biology

Background:

  • The insulin-like growth factor (IGF) pathway is integral to cell growth, differentiation, and proliferation.
  • Dysregulation of the IGF system is implicated in breast cancer development and progression.
  • Targeting the IGF axis offers a potential strategy to overcome resistance to existing breast cancer therapies.

Purpose of the Study:

  • To review the current status of targeting the IGF system in breast cancer therapeutics.
  • To discuss the future perspectives of IGF-system modulators in breast cancer treatment.

Main Methods:

  • Literature review of studies on IGF pathway and breast cancer.
  • Analysis of clinical development of IGF-system modulators.
  • Discussion of therapeutic strategies and limitations.

Main Results:

  • The IGF pathway plays a critical role in breast carcinogenesis.
  • Targeting IGF offers a promising approach to bypass treatment resistance.
  • Current IGF-system modulators exhibit notable limitations in early clinical development.

Conclusions:

  • The IGF system is a relevant therapeutic target for breast cancer.
  • Further research and development are needed to overcome limitations of IGF-system modulators.
  • Optimizing IGF-axis targeting holds potential for improved breast cancer treatment outcomes.

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 specific...
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...
Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but this inhibition is released...
Glucagon-like Receptor Agonists01:24

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...
Transducer Mechanism: Enzyme-Linked Receptors01:27

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
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...
