Insights

Sirtuins regulate cellular processes and their roles in cancer are complex, acting as both tumor suppressors and oncogenic drivers. Targeting the Sirtuin pathway offers a promising strategy for precision oncology.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • Sirtuins (SIRT1-SIRT7) are NAD+-dependent histone deacetylases crucial for cellular homeostasis.
  • Cancer cells hijack cellular processes, promoting metastasis and angiogenesis for survival.

Purpose of the Study:

  • To review the multifaceted roles of Sirtuins in cancer, focusing on oxidative stress, redox signaling, and angiogenesis.
  • To explore Sirtuin interactions with key transcription factors and their impact on cancer progression.
  • To investigate Sirtuin involvement in tumor immunosuppression and identify therapeutic targets.

Main Methods:

  • Literature review of Sirtuin functions in various cancers.
  • Analysis of Sirtuin interactions with transcription factors (p53, FOXO, HIF-1α).
  • Network-based analysis to identify regulatory axes (e.g., miRNA-Transcription Factor-Sirtuin).
  • Molecular docking to elucidate structural interactions (SIRT1-HIF-1α).

Main Results:

  • Sirtuins exhibit context-dependent roles as tumor suppressors or oncogenic drivers.
  • Sirtuins modulate pathways involving p53, FOXO, and HIF-1α in breast, oral, and liver cancers.
  • Sirtuins influence FOXP3 expression and Treg differentiation, contributing to immunosuppression.
  • miR-34a identified as a key regulator; SIRT1-HIF-1α interaction confirmed.

Conclusions:

  • Sirtuins are critical regulators in cancer development and progression.
  • The miRNA-Transcription Factor-Sirtuin axis presents a viable therapeutic framework.
  • Sirtuins hold significant potential as targets for precision oncology and novel anti-cancer therapies.

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 Pathway01:22

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...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...
