Abstract

Insights

Sirtuin 1 (SIRT1) regulates mammalian metabolism and is a key metabolic sensor. Its function is influenced by metabolic diseases, offering potential therapeutic targets for conditions like cancer.

Area of Science:

  • Biochemistry
  • Cellular Biology
  • Metabolic Regulation

Background:

  • Sirtuin 1 (SIRT1) plays a crucial role in cellular processes, including chromatin structure, remodeling, and gene expression.
  • SIRT1's activity is intrinsically linked to cellular homeostasis and metabolic status.

Purpose of the Study:

  • To review recent discoveries on SIRT1's regulation of mammalian metabolism.
  • To explore the impact of metabolic abnormalities in disease on SIRT1 function, considering its dependence on NAD.
  • To examine the interplay between SIRT1, mitochondrial biogenesis, redox pathways, and angiogenesis.

Main Methods:

  • Literature review of recent studies on SIRT1 and metabolic regulation.
  • Analysis of signaling pathways integrating energy metabolism and homeostasis.
  • Examination of SIRT1-mediated deacetylation of key metabolic regulators.

Main Results:

  • SIRT1 integrates diverse signaling pathways to regulate energy metabolism and homeostasis.
  • SIRT1 influences mitochondrial biogenesis, cellular redox, and angiogenesis.
  • SIRT1-mediated deacetylation of transcriptional regulators and enzymes is a key mechanism.

Conclusions:

  • SIRT1 functions as a metabolic sensor, directly coupled with homeostasis.
  • Disease-related metabolic abnormalities can impair SIRT1 functioning.
  • SIRT1's role in disease, particularly cancer survival, presents potential therapeutic targets.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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.

PI3K/mTOR/AKT Signaling Pathway

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 rapamycin-insensitive companion...
Regulation of Metabolism01:19

Regulation of Metabolism

Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...
Replicative Cell Senescence02:15

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...
Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

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,...
