Nanoscale Systems for Local Activation of Hypoxia-Inducible Factor-1 Alpha: A New Approach in Diabetic Wound Management.

Chronic wounds in diabetic patients experience significant clinical challenges due to compromised healing processes. Hypoxia-inducible factor-1 alpha (HIF-1α) is a critical regulator in the cellular response to hypoxia, enhancing angiogenesis and tissue restoration. Nevertheless, the cellular response to the developed chronic hypoxia within diabetes is impaired, likely due to the destabilization of HIF-1α via degradation by prolyl hydroxylase domain (PHD) enzymes.

PU-H71 (NSC 750424): a molecular masterpiece that targets HSP90 in cancer and beyond.

Heat shock protein 90 (HSP90) is a pivotal molecular chaperone with multifaceted roles in cellular health and disease. Herein, we explore how HSP90 orchestrates cellular stress responses, particularly through its partnership with heat shock factor 1 (HSF-1). PU-H71, a selective inhibitor of HSP90, demonstrates significant potential in cancer therapy by targeting a wide array of oncogenic pathways.

Cydonia oblonga extract mediated biosynthesis of gold nanoparticles: Analysis of its anti-oral cancer and antioxidant properties.

Here, using natural and biological macromolecules derived from Cydonia oblonga extract, we have developed a green protocol for the biogenic made Au NPs. Under ultrasonic activated conditions, the Cydonia oblonga phytomolecules were employed as an efficient green reducing agent for the Au ions to the Au NPs. Additionally, by encapsulating or capping, they allowed the Au NPs to stabilize on their own.
