Summary
This summary is machine-generated.Mutations in the POLE gene in endometrial cancer impact DNA repair and protein interactions. These POLE mutations may influence platinum resistance and trigger an immune response, affecting patient prognosis.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Endometrial cancer (EC) is a common gynecologic malignancy.
- The DNA Polymerase Epsilon (POLE) gene plays a critical role in DNA replication and repair.
- Understanding POLE mutations in EC is crucial for predicting disease behavior and treatment response.
Purpose Of The Study
- To characterize POLE mutations in endometrial cancer.
- To analyze the functional impact of these POLE mutations on protein structure and interactions.
- To investigate the relationship between POLE mutational status, patient survival, and prognosis in EC.
Main Methods
- Retrieved POLE mutations in EC from the Catalogue of Somatic Mutations in Cancer database.
- Analyzed mutation impact using HOPE server and built protein-protein interaction networks with Cytoscape.
- Correlated clinical data from cBioPortal and immune cell infiltration using TIMER2.0.
Main Results
- Identified thirty POLE mutations in EC, with p.P286R, p.V411L, and p.A456P being frequent and likely pathogenic.
- POLE interacts with proteins involved in DNA repair, cell proliferation, and platinum resistance.
- POLE-mutated EC tumors showed increased infiltration of specific immune cells (e.g., CD8+ T cells, M1 macrophages).
Conclusions
- POLE mutations can alter DNA polymerase epsilon function and protein interactions, potentially affecting DNA repair mechanisms.
- POLE mutations may contribute to platinum resistance but can also stimulate an anti-tumor immune response.
- These findings suggest POLE mutational status is a significant factor in EC prognosis and immune microenvironment.

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
Signal sequences are short amino acid sequences that guide newly synthesized proteins to their proper location within the cell. Classical signal sequences are fifteen to sixty amino acids long and present at the N-terminus of a polypeptide chain. Each signal sequence has a conserved segment of basic residues towards their N terminus, a hydrophobic core, and a C-terminus rich in polar residues. The C-terminus also contains a signal cleavage site and features a -3 -1 sequence motif. The -3-1...
