Insights

EphA2, a tyrosine kinase, is highly produced in tumors and shows potential for cancer treatment. Despite clinical trials, targeting EphA2 for anticancer strategies requires further insights.

Area of Science:

  • Cellular signaling
  • Molecular biology
  • Oncology

Background:

  • Eph receptors and ephrin ligands form a critical cell signaling network.
  • EphA2 tyrosine kinase is upregulated in tumors but low in normal tissues.
  • Extensive research has elucidated EphA2 functions over 30 years.

Purpose of the Study:

  • To review the role of EphA2-ephrin A1 signaling in carcinogenesis.
  • To examine EphA2's involvement in resistance to molecular-targeted agents.
  • To provide insights into EphA2 as a potential cancer treatment target.

Main Methods:

  • Literature review of EphA2 signaling.
  • Analysis of EphA2's role in cancer development.
  • Examination of EphA2's function in drug resistance.

Main Results:

  • EphA2-ephrin A1 signaling contributes to cancer development.
  • EphA2 plays a role in resistance to targeted cancer therapies.
  • Compounds targeting EphA2 have shown limited clinical success.

Conclusions:

  • EphA2 is a promising target for cancer therapy.
  • Further research is needed to optimize EphA2-targeting anticancer strategies.
  • Understanding EphA2's multifaceted roles is crucial for effective treatment.

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...

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.

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

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...
