Mitogens and the Cell Cycle

6.4K
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...

Abnormal Proliferation02:23

Abnormal Proliferation

4.5K
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...

mTOR Signaling and Cancer Progression

3.8K
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...

Summary

Insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) is overexpressed in esophageal squamous cell carcinoma (ESCC), driving cancer progression. Targeting the IGF2BP2-hepatoma-derived growth factor (HDGF) axis may offer new therapeutic strategies for ESCC.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Genomics

Background:

  • Esophageal squamous cell carcinoma (ESCC) is a major global health concern.
  • Understanding the molecular mechanisms driving ESCC progression is crucial for developing effective treatments.

Purpose of the Study:

  • To investigate the role of Insulin-like Growth Factor 2 mRNA-Binding Protein 2 (IGF2BP2) in the progression of ESCC.
  • To elucidate the molecular mechanisms underlying IGF2BP2's function in ESCC.

Main Methods:

  • Analysis of The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets for m6A-associated gene expression in ESCC.
  • In vitro and in vivo experiments to assess the functional impact of IGF2BP2.
  • Investigation of IGF2BP2's interaction with hepatoma-derived growth factor (HDGF) transcripts.

Main Results:

  • IGF2BP2 is significantly overexpressed in ESCC tissues, correlating with poor patient prognosis.
  • Modulating IGF2BP2 levels affects ESCC cell proliferation, migration, invasion, and tumor growth.
  • IGF2BP2 binds to and stabilizes HDGF transcripts in an m6A-dependent manner, enhancing HDGF expression.

Conclusions:

  • The IGF2BP2-HDGF axis plays a critical role in ESCC progression.
  • IGF2BP2 represents a potential therapeutic target for ESCC treatment.
