Tumor Progression02:07

Tumor Progression

6.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
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...

Cancer Stem Cells and Tumor Maintenance

4.3K
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...

Adaptive Mechanisms in Cancer Cells

5.7K
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,...

Disorders of Leukocytes01:27

Disorders of Leukocytes

2.3K
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Cancer02:18

Cancer

51.7K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Abnormal Proliferation02:23

Abnormal Proliferation

4.0K
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...

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • Cancer cells display variable tumorigenic potential after transplantation.
  • The molecular mechanisms governing cancer cell activity are not fully understood.
  • T-cell acute lymphoblastic leukemia (T-ALL) is a significant area of cancer research.

Purpose of the Study:

  • To investigate the role of Akt signaling in regulating leukemia-propagating potential.
  • To determine how Akt signaling influences the proliferation rate of cancer cells.
  • To elucidate the distinct molecular pathways involved in T-ALL progression.

Main Methods:

  • Experimental transplantation of individual cancer cells.
  • Analysis of Akt signaling pathways in T-ALL models.
  • Comparative studies of proliferation rates and tumor-initiating capacities.

Main Results:

  • Akt signaling was found to regulate leukemia-propagating potential.
  • Distinct molecular pathways were identified for regulating proliferation rate.
  • These effects were specifically observed in T-ALL.

Conclusions:

  • Akt signaling plays a dual role in T-ALL, affecting both stemness and proliferation.
  • Understanding these distinct pathways offers potential therapeutic targets for T-ALL.
  • Further research into Akt signaling could improve treatment strategies for leukemia.
