Amyloid Fibrils03:03

Amyloid Fibrils

10.2K
Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Cancer-Critical Genes I: Proto-oncogenes

9.1K
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...

mTOR Signaling and Cancer Progression

3.6K
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...

Area of Science:

  • Biochemistry
  • Cell Biology
  • Neuroscience

Background:

  • The normal cellular prion protein (PrP(C)) is a conserved cell surface glycoprotein found in mammals.
  • While its role in prion diseases is established, the physiological functions of PrP(C) are not fully understood.
  • Numerous functions have been proposed for PrP(C) based on cell model studies.

Purpose of the Study:

  • To review the potential roles of PrP(C) in normal cell physiology.
  • To focus on the contribution of PrP(C) to tumorigenesis.

Main Methods:

  • Literature review of existing studies on PrP(C) function.
  • Analysis of cell model data investigating PrP(C) roles.
  • Synthesis of findings related to PrP(C) and cancer development.

Main Results:

  • PrP(C) is implicated in various cellular processes, including cell adhesion, signal transduction, and copper metabolism.
  • Emerging evidence suggests a role for PrP(C) in the regulation of cell proliferation, differentiation, and apoptosis.
  • Studies indicate that PrP(C) expression is altered in several types of tumors and may influence tumor growth and metastasis.

Conclusions:

  • PrP(C) likely plays multifaceted roles in normal cell physiology.
  • The involvement of PrP(C) in tumorigenesis warrants further investigation.
  • Understanding PrP(C) functions could offer new insights into cancer biology and potential therapeutic strategies.
