Tumor Progression02:07

Tumor Progression

6.5K
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...

Somatic to iPS Cell Reprogramming

2.3K
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...

Methods of Nuclear Reprogramming

1.9K
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...

Introduction to Nuclear Reprogramming

2.0K
Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

5.1K
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...

Summary

Embryonic development, inflammation, and cancer share similar cellular traits like rapid division and plasticity. Oncofetal reprogramming helps tumors evade immune responses, promoting growth and spread.

Area of Science:

  • Oncology
  • Developmental Biology
  • Immunology

Background:

  • Embryonic development involves rapid cell division, plasticity, and a vascular microenvironment.
  • Tumorigenesis shares these characteristics, with malignant cells proliferating and exhibiting plasticity.
  • Tumor microenvironments often feature immunosuppressive elements, mirroring aspects of fetal development.

Purpose of the Study:

  • To discuss the similarities between embryogenesis, inflammation, and tumorigenesis.
  • To describe oncofetal reprogramming mechanisms.
  • To explain how these mechanisms promote tumor growth and metastasis by evading immune responses.
