A programmable DNA tetrahedron platform for selective and efficient capture of cells and proteins

Describes a programmable tetrahedral DNA nanostructure platform and stepwise protocol for precisely placing capture ligands to enrich cells and proteins for regenerative and analytical uses.

Key takeaways
  • 2: Overview of the procedure from topology-guided design to in vivo validation of TDN capture platforms.
  • Conventional multivalent platforms suffer from uncontrolled ligand distribution and poor spatial alignment.
  • This versatile platform enables the rational design of high-efficiency capture agents for diverse biological targets.

CRISPR makes prostate cancer vulnerable to immunotherapy (Science Daily - Health & Medicine)

CRISPR makes prostate cancer vulnerable to immunotherapy

This preview invites you into a research feature about an experimental RNA-targeting CRISPR strategy that aims to sensitize immune-cold prostate tumors to immunotherapy.

Key takeaways
  • RNA-targeting CRISPR Cas13 system was used to lengthen shortened SPSB1 mRNA in prostate cancer cells.
  • Restoring SPSB1 mRNA length reduced SPSB1 protein and rescued MHC-I presentation on tumor cells.
  • Combining this mRNA engineering with immune checkpoint therapy dramatically improved anti-tumor responses in mice.

Synthetic ion channel inhibitors enhance plant drought tolerance (Nature - Biotechnology)

Synthetic ion channel inhibitors enhance plant drought tolerance

Report on synthetic voltage-dependent potassium channel inhibitors that trigger stomatal closure and boost plant drought tolerance by altering guard cell ion dynamics.

Key takeaways
  • Chemical screen identified NS5806 as a KAT1 inhibitor reducing channel activity by about 55%.
  • Rationally designed analog, UA49, increased KAT1 inhibition to 79% and showed stronger KAT2 inhibition.
  • NS5806 and UA49 raised cytosolic Ca2+ in guard cells and enhanced plant drought resistance when applied.

Fight Aging! Newsletter, July 27th 2026

A newsletter roundup covering new research on neuromuscular junction failure in sarcopenia, immune cell senescence driving bone disease, and clinical debate over p-tau217 biomarker follow-up actions.

Key takeaways
  • NMJ transmission failure and localized loss of NaV1.4 channel contribute to age-related muscle weakness.
  • Small molecule ClC-1 inhibition restored NMJ transmission and improved motor function in aged rats.
  • Immune cell senescence promotes bone resorption and impairs formation with varied roles across bone diseases.
