SIRT1

SIRT1 is a signaling regulator and protein deubiquitination target that appears to sit at the intersection of autophagy, aging, and disease-associated signaling. It is implicated in autophagy and human longevity, and the literature here highlights modulation by bioactive natural compounds as well as direct post-translational regulation by l3emp. In one study, SIRT1 was described as the signaling regulator through which natural products modulate autophagy, while another reported that L3EMP catalyzes SIRT1 deubiquitination, linking it to lung adenocarcinoma progression. Computational work also identified SIRT1 as the strongest-binding target of vernomenin, with stable molecular dynamics supporting the vernomenin–SIRT1 complex in a fever-focused screening study. Overall, these findings position SIRT1 as a mechanistically important regulator in aging-related pathways and as a druggable node in inflammatory and cancer-related contexts.

Autophagy and Aging

  • Bioactive natural compounds were reported to modulate autophagy through SIRT1, supporting its role as a signaling regulator in longevity-related biology. (PMID:41830033)
  • The study explicitly framed SIRT1 in the context of human aging and longevity, consistent with its relevance to autophagy control. (PMID:41830033)
  • This work was published in a 2026 Nutrients article on mechanistic modulation of autophagy by natural products. (PMID:41830033)

Cancer

  • l3emp was shown to catalyse deubiquitination of SIRT1, and this mechanism was linked to lung adenocarcinoma progression. (PMID:41942609)
  • The finding suggests SIRT1 is a post-translationally regulated node in oncogenic signaling rather than only a transcriptional or metabolic regulator. (PMID:41942609)
  • This was reported in a 2026 British Journal of Cancer study describing a novel microprotein-driven cancer mechanism. (PMID:41942609)

Fever / Natural Product Targeting

  • Vernomenin showed the strongest binding affinity to SIRT1 in docking analyses and maintained stable complex dynamics in molecular dynamics simulations. (PMID:41691789)
  • The study positioned SIRT1 as a molecular target in a fever-related network pharmacology screen of Vernonia amygdalina compounds. (PMID:41691789)
  • These computational results were published in a 2026 Journal of Molecular Graphics and Modelling paper as a preliminary assessment for fever targeting. (PMID:41691789)
