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...

Cancer Stem Cells and Tumor Maintenance

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Loss of Tumor Suppressor Gene Functions

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Adaptive Mechanisms in Cancer Cells

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Area of Science:

Oncology
Cancer Biology
Tumor Microenvironment

Background:

Dormant, microscopic tumors are highly prevalent in healthy individuals.
These tumors are asymptomatic, non-invasive, and often undetected due to their small size.
Tumor dormancy is a critical phase where neoplasms remain static without progressive growth.

Purpose of the Study:

To review observations, models, and experimental approaches for studying tumor dormancy.
To discuss the mechanisms underlying tumor dormancy, including angiogenesis.
To highlight the implications of tumor dormancy for early cancer detection and therapeutic strategies.

Main Methods:

Review of existing literature on tumor dormancy.
Analysis of models and experimental approaches to study dormant neoplasms.
Discussion of regulatory mechanisms and the angiogenic switch in tumor progression.

Main Results:

Tumor dormancy is a common phenomenon, not necessarily indicative of active cancer.
Angiogenesis is a critical factor for the transition from dormant to progressive tumor growth.
Dormancy can occur in primary tumors, as residual disease, or as micrometastases.

Conclusions:

Elucidating tumor dormancy mechanisms is crucial for identifying early cancer biomarkers.
Developing therapies that promote dormancy could offer novel treatment rationales.
Further research into tumor dormancy is needed despite its high prevalence and clinical significance.
