Insights

Epidermal growth factor receptor (EGFR) signaling regulates cell growth and survival. Dysregulation of EGFR is implicated in cancer, making it a target for cancer therapies.

Area of Science:

  • Cell biology
  • Molecular oncology
  • Biochemistry

Background:

  • Cellular processes like growth and survival are regulated by external stimuli.
  • Signal transduction relies on cell surface or transmembrane receptors.
  • Epidermal growth factor receptor (EGFR) is a key type I receptor tyrosine kinase involved in cellular signaling.

Purpose of the Study:

  • To review the structural and physiological aspects of EGFR and its ligands.
  • To elucidate the role of EGFR in cancer development and progression.
  • To discuss EGFR-targeted therapeutic strategies.

Main Methods:

  • Literature review of existing research on EGFR.
  • Analysis of EGFR's role in cellular pathways.
  • Examination of EGFR's involvement in cancer pathogenesis.

Main Results:

  • EGFR and its ligands regulate multiple critical cellular pathways.
  • EGFR signaling is extensively studied for its biological and pathophysiological significance.
  • Evidence strongly links EGFR to the pathogenesis and progression of various cancers.

Conclusions:

  • EGFR plays a significant role in cellular regulation.
  • EGFR is a crucial factor in cancer development.
  • Targeting EGFR offers a promising therapeutic avenue for cancer 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...

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...

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.

The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...

Receptor Downregulation in MVBs01:15

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...

Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...
