Summary
Sirtuins (SIRTs) are key metabolic sensors. This review analyzes transgenic mouse models to clarify SIRT functions in various diseases, guiding the development of targeted therapies.
Area of Science:
- Biochemistry and Molecular Biology
- Genetics and Genomics
- Cellular Biology
Background:
- Sirtuins (SIRT1-SIRT7) are NAD+-dependent deacylases acting as metabolic sensors.
- Dysregulated SIRT activity is implicated in aging, metabolic syndrome, cardiovascular disease, neurodegeneration, cancer, and immune disorders.
- Robust human evidence and targeted therapies for SIRTs are currently limited.
Purpose of the Study:
- To synthesize evidence from Sirt1-7 transgenic mouse models.
- To elucidate core cellular processes governed by SIRTs across organ systems.
- To guide the development of SIRT-targeted therapies for human diseases.
Main Methods:
- Review of transgenic mouse models (knockout and overexpression) across various disease contexts.
- Comparative analysis of SIRT functions in cardiovascular, respiratory, digestive, nervous, endocrine, urogenital, musculoskeletal, malignant, and immune systems.
- Summary of small-molecule SIRT modulators (activators, inhibitors, degraders) from clinical and preclinical studies.
Main Results:
- Identified SIRT1, SIRT3, and SIRT6 as central regulatory SIRTs.
- Characterized SIRT2, SIRT4, SIRT5, and SIRT7 as context-dependent modifiers.
- Detailed organ- and cell type-specific functions of different SIRT isoforms.
Conclusions:
- SIRT modulation holds promise for treating human diseases.
- Specific SIRT isoforms, tissues, and disease contexts require targeted therapeutic strategies.
- Further research is needed to address contradictions and knowledge gaps in SIRT research.

02:30siRNA - Small Interfering RNAs
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...

01:27Transducer Mechanism: Enzyme-Linked Receptors
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.

01:31Regulation of the Unfolded Protein Response
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
