Insights

Targeting ErbB receptors shows promise in cancer treatment, but resistance is a significant challenge. Understanding resistance mechanisms and developing combination therapies may improve patient outcomes for cancers like HER-2 positive breast cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • The ErbB receptor family plays a crucial role in normal cell growth and cancer.
  • Targeting ErbB receptors with inhibitors has shown success in cancer therapy.
  • Substantial resistance to ErbB inhibitor monotherapy necessitates further research.

Purpose of the Study:

  • To understand the biology of ErbB receptor inhibitors.
  • To explore mechanisms of resistance to ErbB inhibitors.
  • To evaluate strategies for overcoming resistance and improving cancer treatment.

Main Methods:

  • Review of experimental evidence on ErbB receptor inhibitor resistance.
  • Analysis of ongoing clinical trials for metastatic breast cancer.
  • Investigation of novel ErbB receptor inhibitors.

Main Results:

  • Resistance to ErbB inhibitor monotherapy is a significant clinical issue.
  • Experimental data provides insights into resistance mechanisms.
  • Resistance can be reversed in certain experimental models.
  • Clinical trials are assessing dual EGFR/HER-2 targeting agents.

Conclusions:

  • A deeper understanding of ErbB biology is essential for effective therapeutic strategies.
  • Combination therapies and novel inhibitors are crucial for overcoming resistance.
  • Continued research is expected to improve patient outcomes in ErbB-driven cancers, particularly HER-2 positive breast cancer.

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...
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...
Treatment Resistant Cancers02:56

Treatment 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...
Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
