Skin Cancer

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 Progression

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...

Abnormal Proliferation

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...

Area of Science:

Oncology
Molecular Biology
Genetics

Background:

Melanoma development involves genetic alterations activating critical signaling pathways.
RAS-RAF-MAP kinase and PI3-kinase pathways are frequently altered in melanoma.
Mutations in BRAF, NRAS, KIT, and GNAQ lead to MAP-kinase activation.

Purpose of the Study:

To review genetic alterations in melanoma.
To discuss the role of signaling pathway activation in melanoma growth.
To explore therapeutic interventions targeting these pathways.

Main Methods:

Analysis of genetic alterations in melanoma.
Review of signaling pathway activation.
Evaluation of therapeutic interventions.

Main Results:

Recurrent mutations activate growth-promoting signaling pathways in melanoma.
Mutations in BRAF, NRAS, KIT, and GNAQ occur mutually exclusively.
Loss of PTEN function is common in the PI3-kinase cascade, often with BRAF mutations.

Conclusions:

Constitutive activation of signaling pathways confers a growth advantage and dependency.
Targeting activated signaling components presents therapeutic opportunities.
Kinases involved in these pathways are under evaluation for melanoma treatment.
