Summary
Cell polarity is crucial for healthy cells, but its disruption is a cancer hallmark. Understanding how polarity protein alterations drive cancer may lead to new diagnostic and therapeutic strategies.
Area of Science:
- Cell Biology
- Cancer Biology
- Molecular Oncology
Background:
- Cell polarity defines the organization of cells and tissues, essential for normal function.
- Aberrant cell polarity is a recognized characteristic of cancer cells.
- Key polarity proteins are frequently altered in cancer, but their precise roles remain unclear.
Purpose of the Study:
- To review recent findings on the involvement of polarity proteins in cancer development.
- To elucidate the molecular mechanisms linking polarity alterations to oncogenesis.
- To explore the potential of targeting cell polarity for cancer prediction, diagnosis, and treatment.
Main Methods:
- Literature review of recent research findings.
- Analysis of molecular alterations in polarity proteins in various cancers.
- Discussion of the functional implications of these alterations in cancer progression.
Main Results:
- Identified specific polarity proteins and their altered expression or function in cancer.
- Highlighted the link between disrupted cell polarity and key cancer hallmarks.
- Provided insights into how polarity pathways are co-opted during tumorigenesis.
Conclusions:
- Altered cell polarity proteins are significantly involved in cancer development and progression.
- Understanding these molecular changes offers potential for novel cancer biomarkers.
- Targeting cell polarity pathways presents a promising avenue for future cancer therapies.

2.3K
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,...

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...

02:21Cancers Originate from Somatic Mutations in a Single Cell
12.0K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

02:40Cancer Stem Cells and Tumor Maintenance
4.9K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

01:21Cell Polarization by Rho Proteins
2.7K
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

01:19Cadherins in Tissue Organization
3.0K
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.
