mTOR Signaling and Cancer Progression

4.5K
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...

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

The Retinoblastoma Gene

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.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Cancer-Critical Genes II: Tumor Suppressor Genes

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...

Area of Science:

  • Genetics
  • Molecular Biology
  • Medical Science

Background:

  • Tuberous sclerosis complex (TSC) is a childhood-onset monogenic disorder.
  • Characterized by hamartoma formation in multiple organs, leading to significant morbidity and reduced lifespan.
  • Involves tumor suppressor genes TSC1 and TSC2, and the mTORC1 signaling pathway.

Purpose of the Study:

  • To review the current genetic aspects of tuberous sclerosis complex.
  • To elucidate the role of TSC1 and TSC2 genes in TSC pathogenesis.
  • To discuss the implications of mTORC1 pathway research for clinical practice.

Main Methods:

  • Literature review of current research on TSC genetics.
  • Analysis of the role of TSC1 and TSC2 genes.
  • Examination of the mammalian target of rapamycin complex 1 (mTORC1) signaling pathway.

Main Results:

  • Identification of TSC1 and TSC2 as causative genes for TSC.
  • Elucidation of the critical role of the mTORC1 pathway in hamartoma formation.
  • Rapamycin and its analogues are effective mTORC1 inhibitors used in clinical practice.

Conclusions:

  • Next-generation sequencing is crucial for advancing TSC tumorigenesis research.
  • Future research may lead to novel therapeutic strategies for TSC.
  • Continued genetic research holds promise for improved patient outcomes.
