Summary
E-cadherin expression decreases significantly during cervical carcinogenesis, with the lowest levels observed in squamous cell carcinoma (SCC) compared to squamous intraepithelial lesions (SILs) and cervicitis. This suggests E-cadherin loss is a key event in cervical cancer development.
Area of Science:
- Oncology
- Cell Biology
- Gynecologic Pathology
Background:
- E-cadherin is a crucial cell adhesion molecule.
- Altered E-cadherin expression is implicated in various cancers.
- Understanding E-cadherin's role in cervical carcinogenesis is vital for early detection and treatment.
Purpose of the Study:
- To investigate the immunoexpression of E-cadherin during the progression of cervical carcinogenesis.
- To correlate E-cadherin expression patterns with different stages of cervical lesions.
Main Methods:
- Immunohistochemical analysis of E-cadherin expression.
- Study included cases of cervicitis, squamous intraepithelial lesions (SILs), and squamous cell carcinoma (SCC) of the uterine cervix.
Main Results:
- E-cadherin membrane expression was significantly reduced in SCC (17%) compared to SILs (73%) and cervicitis (88%).
- In SILs, reduced E-cadherin expression correlated with less differentiated cells in the basal epithelium.
- Absence of E-cadherin expression is more frequent in SCC than in SILs or cervicitis.
Conclusions:
- E-cadherin plays an essential role in cervical carcinogenesis.
- E-cadherin expression patterns vary with epithelial thickness during cervical carcinogenesis.
- E-cadherin loss is a significant molecular event in the progression to cervical cancer.

01:19Cadherins in Tissue Organization
3.4K
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.

01:25Structure of Cadherins
3.9K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
1.8K
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.

01:24Adherens Junctions
5.7K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
