Bcl-2 family members: essential players in skin cancer
1Cell Death Research & Therapy Unit, Department for Molecular Cell Biology, Catholic University of Leuven, Leuven, Belgium.
Abstract:
Skin cancer has reached epidemic proportions and is considered to be a direct consequence of ultraviolet (UV) radiation exposure. Excessive exposure of epidermal cells to UV results in apoptosis of irreparably damaged cells to avoid malignant transformation. The Bcl-2 family of proteins is emerging as a crucial regulator of epidermal homeostasis and cell's fate in the stressed skin. Not surprisingly, deregulation of Bcl-2 family members is also chiefly involved in skin carcinogenesis and response to cancer therapy. Here we discuss the physiopathological role of epidermal Bcl-2 family members, their implications in skin carcinogenesis and as potential targets in cancer therapy.
Insights
Skin cancer, driven by UV radiation, involves cell death regulated by Bcl-2 proteins. Understanding these proteins
Area of Science:
- Dermatology and Oncology
- Molecular Biology
- Cell Biology
Background:
- Skin cancer incidence is rising globally, primarily linked to ultraviolet (UV) radiation exposure.
- UV radiation induces DNA damage in epidermal cells, triggering apoptosis to prevent malignant transformation.
- The Bcl-2 protein family plays a critical role in regulating skin cell survival and death pathways.
Purpose of the Study:
- To elucidate the physiopathological roles of Bcl-2 family proteins in the epidermis.
- To investigate the involvement of Bcl-2 family members in skin carcinogenesis.
- To explore the potential of Bcl-2 family proteins as therapeutic targets for skin cancer.
Main Methods:
- Review of current literature on Bcl-2 family proteins and skin cancer.
- Analysis of the role of Bcl-2 family in epidermal homeostasis and response to UV stress.
- Examination of the link between Bcl-2 deregulation and skin tumor development.
Main Results:
- Bcl-2 family proteins are key regulators of cell fate in UV-stressed skin.
- Dysregulation of Bcl-2 family members is implicated in the development of skin cancer.
- Altered expression of Bcl-2 proteins is observed in various skin malignancies.
Conclusions:
- Bcl-2 family proteins are crucial for maintaining epidermal integrity and preventing skin cancer.
- Targeting Bcl-2 family members offers a promising therapeutic strategy for skin cancer treatment.
- Further research into Bcl-2 family functions could lead to novel anti-skin cancer therapies.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
