Summary
Endothelial cell-specific molecule 1 (ESM1) is overexpressed in cervical cancer, driving tumor growth and metastasis. Silencing ESM1 inhibits cancer progression, suggesting it as a therapeutic target.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Endothelial cell-specific molecule 1 (ESM1) function in cervical cancer is not well understood.
- ESM1 expression is elevated in cervical cancer tissues and correlates with poor patient prognosis.
Purpose of the Study:
- To investigate the role and molecular mechanisms of ESM1 in human cervical cancer.
- To evaluate ESM1 as a potential diagnostic marker and therapeutic target.
Main Methods:
- Bioinformatics analysis and RNA sequencing.
- In vitro studies using ESM1 knockdown (shRNA, CRISPR/Cas9) and overexpression (lentiviral).
- In vivo xenograft models in mice.
Main Results:
- ESM1 upregulation promotes cervical cancer cell proliferation, migration, invasion, and inhibits apoptosis.
- ESM1 influences the PI3K-Akt pathway and epithelial-mesenchymal transition (EMT).
- SYT13 identified as a target gene mediating ESM1's effects on cell migration and invasion.
- ESM1 knockout suppressed tumor growth in vivo, with reduced PI3K-Akt activation and EMT markers.
Conclusions:
- Overexpressed ESM1 drives cervical cancer growth and progression by activating the PI3K-Akt pathway and promoting EMT.
- ESM1 is a potential diagnostic biomarker and therapeutic target for cervical cancer.

02:30Metastasis
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...

01:35Cancer Cell Migration through Invadopodia
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, invadopodia can...
01:10Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
01:19Cadherins in Tissue Organization
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

01:25Selectins
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain, which...
