mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.8K
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...

Induced Pluripotent Stem Cells

4.0K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Cancer-Critical Genes I: Proto-oncogenes

8.8K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
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.
Such genes that act...

Abnormal Proliferation02:23

Abnormal Proliferation

4.5K
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...

Adaptive Mechanisms in Cancer Cells02:53

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,...

  • Cancer Biology
  • Metabolic Reprogramming

Background:

  • Glucose transporter 5 (GLUT5) is increasingly recognized for its role in cancer development.
  • Overexpression of GLUT5 is observed across various cancer types, impacting cellular metabolism.
  • GLUT5's involvement extends beyond metabolism to influence immune evasion in tumors.

Purpose of the Study:

  • To provide a comprehensive overview of GLUT5 overexpression in cancer.
  • To elucidate the dual role of GLUT5 in metabolic reprogramming and immune modulation.
  • To highlight GLUT5 as a potential diagnostic marker and therapeutic target.

Main Methods:

  • Literature review of studies investigating GLUT5 in cancer.
  • Analysis of molecular mechanisms underlying GLUT5 upregulation.
  • Examination of GLUT5's impact on cancer cell metabolism and immune response.

Main Results:

  • GLUT5 upregulation promotes altered fructose metabolism and aerobic glycolysis (Warburg effect) in cancer cells.
  • This metabolic shift provides an alternative energy source, supporting uncontrolled cancer cell proliferation.
  • GLUT5 overexpression contributes to tumor immune evasion, exacerbating tumor progression.

Conclusions:

  • GLUT5 plays a critical dual role in cancer, influencing both metabolism and immune evasion.
  • Targeting GLUT5 presents a potential therapeutic strategy to disrupt cancer vulnerabilities.
