Insights

The tumor suppressor PTEN (phosphatase and tensin homolog deleted on chromosome 10) is crucial for preventing skin cancer. Reduced PTEN function, often due to UV radiation, promotes skin cancer development, offering new therapeutic targets.

Area of Science:

  • Oncology
  • Dermatology
  • Molecular Biology

Background:

  • Skin cancer is the most prevalent cancer in the US, with UV radiation as a primary cause.
  • PTEN (phosphatase and tensin homolog deleted on chromosome 10) is a key tumor suppressor gene frequently altered in human cancers.
  • PTEN counteracts the PI3K/AKT signaling pathway, which is critical in cell growth and survival.

Purpose of the Study:

  • To review the role of PTEN in the development of various skin cancers.
  • To explore the regulation of PTEN by UV radiation in skin carcinogenesis.
  • To identify new therapeutic strategies targeting PTEN pathways for skin cancer prevention and treatment.

Main Methods:

  • Literature review of recent research on PTEN function in skin cancer.
  • Analysis of PTEN's role in basal-cell carcinoma, squamous-cell carcinoma, and melanoma.
  • Examination of UV radiation's impact on PTEN regulation and skin carcinogenesis.

Main Results:

  • PTEN is a critical tumor suppressor in both human and mouse skin cancer models.
  • UV radiation significantly affects PTEN function, contributing to skin carcinogenesis.
  • Altered PTEN function is a common mechanism in the development of basal-cell carcinoma, squamous-cell carcinoma, and melanoma.

Conclusions:

  • Understanding PTEN's role in UV-induced skin cancer is vital for developing targeted therapies.
  • Restoring or enhancing PTEN function presents a promising avenue for skin cancer chemoprevention and treatment.
  • Targeting PTEN pathways offers new opportunities for managing skin cancer by addressing a fundamental mechanism of carcinogenesis.

Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
Skin Cancer01:30

Skin Cancer

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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

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...
Abnormal Proliferation02:23

Abnormal Proliferation

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 daughter...
Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
