Introduction:
Cutaneous melanoma represents < 5% of all skin cancers, but is responsible for the majority of skin cancer-related deaths. Ocular melanoma is the most common primary eye tumor in adults, and accounts for approximately 5% of all melanomas. Despite new diagnostic and therapeutic tools, the overall survival of patients treated for melanoma has not improved and most patients die of metastatic disease. Therefore, clarification of the molecular mechanisms underlying the etiopathogenesis of cutaneous and ocular melanomas may help determining the prognosis and tailoring therapy of patients harboring melanomas.
Areas Covered:
In this review the authors aim to survey relevant research in the molecular mechanisms underlying melanomagenesis, and therapies under evaluation with emphasis in the mTOR pathway.
Expert Opinion:
Despite an increasingly understanding of the genetics and biochemistry of melanoma, the mechanisms underlying their complex interactions are still poorly understood. Their clarification will lead to more successful therapeutic strategies and evidence-based management of patients with melanoma. More active drug combinations together with appropriate melanoma patient stratification based on molecular biomarkers will be essential for new advances in melanoma therapy.
Insights
Understanding melanoma
Area of Science:
- Oncology
- Dermatology
- Ophthalmology
Background:
- Melanoma, though less common than other skin cancers, causes most skin cancer deaths.
- Ocular melanoma is the most frequent primary eye tumor in adults.
- Current treatments have not improved survival rates, with metastasis being the primary cause of death.
Purpose of the Study:
- To review molecular mechanisms of melanoma development.
- To survey current and emerging therapies for melanoma.
- To focus on the role of the mTOR pathway in melanoma.
Main Methods:
- Literature review of research on melanoma.
- Analysis of molecular pathways involved in melanomagenesis.
- Evaluation of therapeutic strategies targeting the mTOR pathway.
Main Results:
- The complex interactions driving melanoma are not fully understood.
- The mTOR pathway is a key area of investigation for melanoma therapies.
- Molecular biomarkers are crucial for patient stratification.
Conclusions:
- Further understanding of melanoma's molecular basis is needed for improved prognosis and treatment.
- Combination therapies and molecular stratification will advance melanoma treatment.
- Targeting the mTOR pathway shows promise for future melanoma therapies.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
