Tumor Progression02:07

Tumor Progression

7.2K
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...

mTOR Signaling and Cancer Progression

4.7K
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...

The Nucleolus02:55

The Nucleolus

10.3K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Reaction Rate02:53

Reaction Rate

62.5K
The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that consume or produce gaseous substances, for example, are conveniently determined by measuring changes in volume or pressure.
The mathematical representation of the change in the concentration of reactants and products, over time, is the rate...

Spontaneous Chemical Reactions
Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...

Measuring Reaction Rates

28.7K
Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a chemical reaction. Optically active substances have the capability of rotating the plane of polarization of linearly polarized light passing through them—a feature called optical rotation. Optical activity is attributed to the molecular structure of substances. Normal monochromatic light is unpolarized and possesses oscillations of the electrical...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Immunology

Background:

  • Sirtuin 1 (SIRT1) is an NAD⁺-dependent class III histone deacetylase.
  • SIRT1 regulates gene expression through deacetylation of lysine residues on histone and non-histone proteins.
  • SIRT1 is implicated in crucial cellular processes including metabolism, aging, tumorigenesis, and inflammation.

Purpose of the Study:

  • To investigate the role of SIRT1 in inhibiting inflammatory responses.
  • To identify SIRT1 targets and signaling pathways involved in sepsis.
  • To provide evidence for SIRT1 as a therapeutic target for inflammatory diseases.

Main Methods:

  • Review of recent studies on SIRT1's role in inflammation.
  • Analysis of signaling pathways regulated by SIRT1 during inflammation.
  • Examination of SIRT1's target genes in the context of sepsis.

Main Results:

  • SIRT1 actively inhibits inflammatory responses by modulating various signaling pathways.
  • SIRT1 plays a significant role in the pathogenesis and progression of sepsis.
  • Research has identified specific signaling pathways and target genes associated with SIRT1's anti-inflammatory effects.

Conclusions:

  • SIRT1 is a critical regulator of inflammatory processes, particularly in sepsis.
  • Understanding SIRT1's mechanisms offers potential for novel therapeutic interventions in sepsis and other inflammatory conditions.
  • SIRT1 represents a promising target for managing uncontrolled inflammatory responses.
