De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.

SIRT Family: Biological Functions and Therapeutic Targets

MedComm, Volume 7, Issue 8, August 2026.
SIRT1–SIRT7 networks from transgenic mice to human‑relevant therapeutic targets. SIRT1–SIRT7 form an isoform‑, organ‑, and disease‑specific regulatory network. Transgenic Sirt1–7 mouse models define central regulatory SIRTs (SIRT1, SIRT3, SIRT6), context‑dependent modifiers (SIRT2, SIRT4, SIRT5, SIRT7), and their key mechanisms and target organs. These

RCSB protein data Bank: Next‐generation advanced search for exploration of experimental structures and computed structure models

Protein Science, Volume 35, Issue 8, August 2026.
Abstract The Protein Data Bank (PDB), established in 1971, is the primary global, open‐access archive for experimentally determined 3D macromolecular structures (proteins, RNA, DNA). The research‐focused RCSB.org web‐portal provides access to these data alongside more than one million machine‐learning‐predicted structure models, greatly expanding the ...

Ammonia Metabolism in the Aging Liver: Emerging Mechanistic Insights

Aging Cell, Volume 25, Issue 8, August 2026.
Liver aging may weaken ammonia‐detoxification reserve by disrupting mitochondrial ureagenesis, GS‐mediated scavenging, glutamine metabolism, and metabolic zonation. This emerging framework links impaired nitrogen handling to potential hepatic stress amplification and systemic crosstalk, while highlighting the need for direct validation in physiological

Metabolic Signatures of Aging and Gametogenesis in Hydra oligactis

Aging Cell, Volume 25, Issue 8, August 2026.
Hydra oligactis undergoes cold‐induced sexual differentiation and aging, culminating in death. GC–MS‐based metabolite profiling revealed signatures of gametogenesis, for example, polyamine accumulation, and of aging, such as loss of cytoprotection and neurotransmitter function, including taurine depletion.
