Insights

Epidermal growth factor receptor (EGFR) may play significant roles in breast cancer progression, including in triple-negative tumors and metastasis. These findings suggest EGFR as a potential therapeutic target for breast malignancies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • Epidermal growth factor receptor (EGFR) is part of the ErbB family of receptor tyrosine kinases.
  • EGFR was previously thought to have a minor role in breast cancer development and progression.
  • Recent research prompts a re-evaluation of EGFR's involvement in breast malignancies.

Purpose of the Study:

  • To review recent findings on EGFR's role in breast cancer.
  • To propose potential functions of EGFR in breast malignancies.
  • To identify contexts where EGFR could be a therapeutic target.

Main Methods:

  • Literature review of recent findings on EGFR in breast cancer.
  • Analysis of potential EGFR roles in specific breast cancer contexts.
  • Discussion of EGFR as a therapeutic target.

Main Results:

  • EGFR may play roles in triple-negative breast tumors.
  • EGFR might be involved in resistance to endocrine therapies.
  • EGFR could contribute to maintaining stem-like tumor cells and bone metastasis.

Conclusions:

  • Recent findings highlight significant roles for EGFR in breast cancer progression.
  • EGFR's involvement in triple-negative tumors, therapy resistance, stemness, and metastasis is proposed.
  • EGFR presents a potential therapeutic target in various breast malignancy contexts.

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.

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
