Abstract:
ALK was first reported in 1994 as a translocation in anaplastic large cell lymphoma and then described with different abnormalities in a number of tumors. Recently, a shortly accumulated biomedical research clarified the numerous biological processes underlying its ability to support cancer development, growth and progression. Advent of precision medicine has finally provided unexpected advances, leading to the development of ALK-targeting inhibitors with superior efficacy as compared with standard chemotherapy regimens, as well as the identification of resistance mechanisms and the creation of 'next-generation' treatments. This review summarizes the current understanding of ALK-driven cancers from the oncogenesis and mutation frequency by The Cancer Genome Atlas database through the diagnostic approach, to an updated portrait of available tyrosine kinase inhibitors, considering their effectiveness in cancer treatment, the molecular reasons of therapeutic failure, and the actual and future ways to overcome resistances.
Insights
Anaplastic Lymphoma Kinase (ALK) plays a key role in cancer development. ALK-targeting inhibitors offer effective treatment, but resistance necessitates next-generation therapies.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Anaplastic Lymphoma Kinase (ALK) was initially identified in anaplastic large cell lymphoma.
- ALK abnormalities are implicated in the development and progression of various cancers.
- Recent research has elucidated ALK's role in oncogenesis.
Purpose of the Study:
- To review the current understanding of ALK-driven cancers.
- To summarize diagnostic approaches and ALK-targeting inhibitors.
- To discuss resistance mechanisms and future therapeutic strategies.
Main Methods:
- Literature review of ALK-driven cancers.
- Analysis of The Cancer Genome Atlas database for mutation frequency.
- Evaluation of tyrosine kinase inhibitors' efficacy and resistance patterns.
Main Results:
- Precision medicine has led to effective ALK-targeting inhibitors.
- Understanding resistance mechanisms is crucial for treatment.
- Next-generation treatments are being developed to overcome resistance.
Conclusions:
- ALK-driven cancers represent a significant area for targeted therapy.

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.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
