Summary
This summary is machine-generated.Methyltransferase-like 3 (METTL3) promotes esophageal squamous cell carcinoma (ESCC) progression. Targeting the METTL3-m<sup>6</sup>A-YTHDC1-AMIGO2 pathway could offer new therapeutic strategies for ESCC.
Area Of Science
- Oncology
- Molecular Biology
- Epigenetics
Background
- Methyltransferase-like 3 (METTL3) upregulation is linked to esophageal cancer progression.
- The precise role of METTL3-mediated N<sup>6</sup>-methyladenosine (m<sup>6</sup>A) modifications in esophageal squamous cell carcinoma (ESCC) remains unclear.
Purpose Of The Study
- To investigate the functional role of METTL3 and its downstream targets in ESCC.
- To elucidate the molecular mechanisms by which METTL3 influences ESCC cell proliferation and metastasis.
Main Methods
- Silencing METTL3 in ESCC cells and assessing proliferation and metastasis in vitro and in vivo.
- Identifying downstream targets using molecular assays.
- Investigating the interaction between METTL3, YTHDC1, and AMIGO2 using RNA immunoprecipitation and splicing analysis.
Main Results
- METTL3 silencing significantly inhibited ESCC cell proliferation and metastasis.
- Adhesion molecule with Ig like domain 2 (AMIGO2) was identified as a downstream target, promoting ESCC malignancy.
- METTL3 knockdown reduced m<sup>6</sup>A modification in AMIGO2 pre-mRNA, and YTHDC1 regulated AMIGO2 expression via splicing modulation.
Conclusions
- The METTL3-m<sup>6</sup>A-YTHDC1-AMIGO2 axis plays a crucial role in regulating ESCC cell proliferation and motility.
- This pathway represents a potential therapeutic target for esophageal squamous cell carcinoma.

A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...
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...
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...
