Summary
Merkel cell polyomavirus (MCPyV) is linked to Merkel cell carcinoma. This study investigates MCPyV
Area of Science:
- Oncology
- Virology
- Dermatology
Background:
- Viruses are implicated in human neoplasms, but their causal roles are debated.
- Polyomaviruses, particularly Merkel cell polyomavirus (MCPyV), possess oncogenic potential.
- MCPyV is established as the cause of Merkel cell carcinoma (MCC).
Purpose of the Study:
- To explore current knowledge on MCPyV presence in keratinocyte carcinomas.
- To investigate the potential role of MCPyV in the genesis of cutaneous carcinomas beyond MCC.
Main Methods:
- Literature review on MCPyV detection in various skin cancers.
- Analysis of studies investigating MCPyV integration and mutations in tumor cells.
Main Results:
- MCPyV is found in approximately 80% of MCC cases.
- MCPyV has also been detected in basal cell carcinoma and squamous cell carcinoma.
- Data on MCPyV's role in other keratinocyte carcinomas is limited and debated.
Conclusions:
- MCPyV is a confirmed etiological agent for MCC.
- Further research is needed to clarify MCPyV's role in other keratinocyte carcinomas.

01:30Skin Cancer
4.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:03Rous Sarcoma Virus (RSV) and Cancer
5.1K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

02:23Abnormal Proliferation
4.6K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

02:38Mitogens and the Cell Cycle
6.6K
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...

02:17The Tumor Microenvironment
6.7K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
