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...

Adaptive Mechanisms in Cancer Cells

6.0K
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-Critical Genes I: Proto-oncogenes

9.2K
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...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

15.2K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

4.1K
The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Cancer Stem Cells and Tumor Maintenance

5.1K
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...

Background:

  • TEAD4 (TEA Domain Transcription Factor 4) is a DNA-binding protein crucial for the YAP transcription complex, regulated by the Hippo pathway.
  • TEAD4 requires co-activators like YAP or TAZ to mediate extracellular signals and regulate target gene transcription.
  • TEAD4 also functions independently of YAP, influencing other signaling pathways.

Purpose of the Study:

  • To review the multifaceted roles of TEAD4, including its oncogenic, epigenetic, and mitochondrial regulatory functions.
  • To discuss the mechanisms underlying TEAD4's involvement in tumorigenesis and its potential as a prognostic marker.
  • To explore TEAD4's novel role in modulating mitochondrial dynamics and cellular metabolism.

Main Methods:

  • Literature review of recent studies on TEAD4 function and regulation.
  • Analysis of TEAD4's involvement in cell proliferation, apoptosis, and differentiation.
  • Examination of TEAD4's role in cancer progression, metastasis, and drug resistance.

Main Results:

  • TEAD4 is essential for blastocyst differentiation but also promotes cancer progression, metastasis, and drug resistance.
  • Upregulation of TEAD4 is observed in various cancers (colon, gastric, breast, prostate) and serves as a prognostic marker.
  • TEAD4 uniquely regulates mitochondrial dynamics and metabolism by controlling electron transport chain gene expression.

Conclusions:

  • TEAD4 is a significant oncogene with diverse functions, including epigenetic regulation and mitochondrial modulation.
