Remote Ischemic Post‐Conditioning Preserves the Neurovascular Unit by Brain‐Derived Gas6 That Drives Monocyte‐Derived Macrophage Reprogramming via Axl and Vimentin after SAH

Advanced Science, EarlyView.
Subarachnoid hemorrhage (SAH) triggers monocyte‐derived macrophage (MDM) infiltration and M1‐like polarization via Vimentin upregulation, leading to neurovascular unit disruption and cognitive dysfunction. Remote ischemic postconditioning (RIPostC) upregulates neuronal Gas6, which activates Axl on MDMs to downregulate Vimentin and drive reparative M2 ...

Withaferin A Analogs That Target the AAA+ Chaperone p97 [PDF]

ACS Chemical Biology, 2015
Understanding the mode of action (MOA) of many natural products can be puzzling with mechanistic clues that seem to lack a common thread. One such puzzle lies in the evaluation of the antitumor properties of the natural product withaferin A (WFA). A variety of seemingly unrelated pathways have been identified to explain its activity, suggesting a lack ...

Tubocapsenolide A Overcomes Oxaliplatin Resistance in Colorectal Cancer by Targeting PLK1 to Impair CEP55–ESCRT‐Associated Vesicular Damage Clearance

Advanced Science, EarlyView.
Oxaliplatin‐resistant colorectal cancer cells utilize a previously unappreciated PLK1‐CEP55‐ESCRT‐driven vesicular extrusion mechanism to clear L‐OHP‐induced cellular damage. The natural withanolide Tubocapsenolide A directly targets and inhibits PLK1 to disrupt this specific damage‐clearance machinery. This blockade induces severe nucleolar stress and

Tackling Chronic Inflammation with Withanolide Phytochemicals—A Withaferin A Perspective [PDF]

Antioxidants, 2020
Chronic inflammatory diseases are considered to be one of the biggest threats to human health. Most prescribed pharmaceutical drugs aiming to treat these diseases are characterized by side-effects and negatively affect therapy adherence. Finding alternative treatment strategies to tackle chronic inflammation has therefore been gaining interest over the

Pharmacokinetic Tuning Redirects β‐Lapachone From NQO1 Bioactivation to Vimentin‐Targeted Oxidation in Cancer

Advanced Science, EarlyView.
Pharmacokinetic tuning acts as a programmable mechanistic switch for β‐lap. Sustained low‐concentration exposure redirects β‐lap from NQO1 bioactivation to direct oxidation of vimentin, driving disulfide crosslinking, proteasomal overload and ferroptosis.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Safety and Metabolic Effects of Withania somnifera Seed Extract and Powder in Rats: Insights From DPP‐4 Molecular Docking

Food Safety and Health, EarlyView.
Withania somnifera seed extract and powder improved metabolic parameters in rats, particularly at higher extract doses, without evident hepatic, renal, hematological, or histopathological toxicity. Molecular docking further predicted strong DPP‐4 inhibitory potential of withanone, supporting the antidiabetic potential of W. somnifera seeds.

Prevention of Early Onset of Breast Cancer With Ashwagandha

Molecular Carcinogenesis, EarlyView.
ABSTRACT Prevention of breast cancer is feasible because many risk factors for this malignancy are known (e.g., family history, reproductive factors, etc.). Medicinal plants and/or their bioactive phytochemicals are attractive for the prevention of early onset of breast cancer due to their generally favorable safety profile.
