Insights

The EGF/ErbB pathway is crucial for ovarian function and cancer. Its dysregulation drives epithelial ovarian cancer, suggesting its members and soluble forms are valuable biomarkers and therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • The Epidermal Growth Factor Receptor (EGFR)/ErbB family of receptor tyrosine kinases is vital for normal ovarian follicle development and ovarian surface epithelium cell growth regulation.
  • Dysregulation of EGFR/ErbB pathways, including mutations and overexpression, contributes to the development and progression of epithelial ovarian cancer.

Purpose of the Study:

  • To investigate the role of the EGF/ErbB pathway in ovarian cancer.
  • To explore the potential of EGFR/ErbB family members and their soluble isoforms as biomarkers and therapeutic targets for epithelial ovarian cancer.

Main Methods:

  • The study reviews existing literature on the EGF/ErbB pathway in ovarian biology and cancer.
  • Analysis of gene expression, mutations, and signaling pathways related to EGFR/ErbB in epithelial ovarian cancer.

Main Results:

  • The EGF/ErbB pathway plays a critical role in normal ovarian function and is frequently dysregulated in epithelial ovarian cancer.
  • Overexpression or mutation of EGFR/ErbB family members and downstream signaling elements are implicated in ovarian cancer etiology and progression.

Conclusions:

  • EGFR/ErbB gene products and their soluble isoforms show potential as clinical biomarkers for disease activity in epithelial ovarian cancer.
  • Soluble receptor isoforms exhibiting growth inhibitory properties are promising candidates for novel ovarian cancer therapeutics.

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...
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...
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...
The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

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.
