Summary
Genetic background influences oncogene-driven cancer stem cell reprogramming. Specific genetic components impact tumor type and resistance, demonstrating polymorphic genetic control over tumoral stem cell fate.
Area of Science:
- Oncology
- Stem Cell Biology
- Genetics
Background:
- Oncogenes can reprogram stem/progenitor cells into malignant cancer stem cells.
- The influence of genetic background on this reprogramming process is not fully understood.
Purpose of the Study:
- To investigate how genetic background affects oncogene-induced tumoral stem cell reprogramming.
- To determine if genetic factors influence the type of cancer that develops from reprogrammed stem cells.
Main Methods:
- Utilized Sca1-BCRABLp210 mice as a model system.
- Compared tumor development in mice with different genetic backgrounds (FVB and B6).
Main Results:
- Sca1-BCRABLp210 mice with FVB genetic components showed resistance to chronic myeloid leukemia (CML).
- Pure Sca1-BCRABLp210 FVB mice developed thymomas, a tumor type not observed in B6 background mice.
- Tumor type in Sca1-BCRABLp210 mice was dependent on the genetic background.
Conclusions:
- Tumoral stem cell reprogramming fate is controlled by polymorphic genetic factors.
- Genetic background plays a critical role in determining cancer stem cell reprogramming and tumor development.

02:40Cancer 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...

01:29Somatic to iPS Cell Reprogramming
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012 for this...

01:24Methods of Nuclear Reprogramming
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for injury repair.
02:15Replicative Cell Senescence
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...
