Abstract

Insights

Altered EGFR-PI3K-Akt-mTOR signaling drives head and neck squamous cell carcinoma (HNSCC) progression. Targeting this pathway offers a promising therapeutic strategy for HNSCC treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Genetics

Background:

  • Head and neck squamous cell carcinomas (HNSCC) involve multiple dysregulated signaling pathways.
  • The EGFR-PI3K-Akt-mTOR pathway is frequently altered and crucial for HNSCC oncogenesis.
  • This pathway regulates key cellular processes like metabolism, growth, and apoptosis, contributing to tumor progression.

Purpose of the Study:

  • To review the current understanding of the EGFR-PI3K-Akt-mTOR signaling pathway in HNSCC.
  • To examine the impact of genetic and epigenetic alterations on this pathway.
  • To highlight the therapeutic potential of targeting this cascade in HNSCC.

Main Methods:

  • Comprehensive literature search of books, journals, databases, and websites.
  • Review and synthesis of current research on EGFR-PI3K-Akt-mTOR signaling in HNSCC.
  • Analysis of genetic and epigenetic alterations affecting the pathway.

Main Results:

  • Genetic and epigenetic alterations in the EGFR-PI3K-Akt-mTOR pathway are common in HNSCC.
  • These alterations lead to oncogene activation or tumor suppressor inactivation.
  • Targeting central nodes of this pathway shows therapeutic promise.

Conclusions:

  • Dysregulation of the EGFR-PI3K-Akt-mTOR pathway is a hallmark of HNSCC.
  • Targeted therapies against this pathway are attractive for molecularly oriented cancer treatment.
  • Further research is needed to fully elucidate pathway biology and optimize therapeutic strategies.

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.

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...
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...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
