Spatial Au+ Mapping Reveals a Self‐Amplifying Anti‐Tumor Immunity Loop Driven by Au(I) Complexes

Advanced Science, EarlyView.
The first report of spatial Au+ mapping of a representative gold complex (Au9). Macrophages, DCs, and tumor cells ranked as the top three in Au+ enrichment after Au9 treatment. Interestingly, Au9 treatment could induce ferroptosis and suppress cellular cholesterol, further eliciting a self‐amplifying anti‐tumor immunity loop.

A population-based study of the risk of osteoporosis and fracture with dutasteride and finasteride

BMC Musculoskeletal Disorders, 2018
Background Dutasteride is a potent inhibitor of 5-alpha reductase enzymes that reduces concentrations of dihydrotestosterone to a greater extent than finasteride. Whether this has adverse implications for bone health is unknown.

5-alpha reductase inhibitors, benign prostatic hyperplasia, and risk of male breast cancer [PDF]

, 2015
5-alpha reductase inhibitors (5-ARI) have been suggested to increase the risk of male breast cancer. The aim of this study was to study the risk of breast cancer in men on 5-ARI, in men with benign prostatic hyperplasia (BPH) not on 5-ARI, and in men ...

ROS/pH‐Responsive Phenylboronic Acid–Chitosan Nanoparticles Improve Silymarin‐Mediated Hepatoprotection After Hepatectomy With Gut‐Liver Axis‐Associated Responses

Advanced Science, EarlyView.
Bioactive phenylboronic acid–chitosan nanoparticles enable responsive silymarin delivery for post‐hepatectomy liver protection. The nanoplatform integrates antioxidant and antibacterial functions, improves hepatic recovery, and is associated with coordinated shifts in gut microbiota, metabolites, cytokines, and hepatic proteomic pathways, suggesting a ...

Hormonal manipulation of lower urinary tract symptoms secondary to benign prostatic obstruction

Indian Journal of Urology, 2014
Although the etiology of lower urinary tract symptoms (LUTS) is often multifactorial, a significant proportion of men over the age of 50 suffer from benign prostatic obstruction (BPO) secondary to benign prostatic hyperplasia. Prostate, being an androgen

Novel Lead Generation through Hypothetical Pharmacophore Three-Dimensional Database Searching:  Discovery of Isoflavonoids as Nonsteroidal Inhibitors of Rat 5α-Reductase

, 2016
A hypothetical pharmacophore of 5α-reductase inhibitors was generated and served as a template in virtual screening. When the pharmacophore was used, eight isoflavone derivatives were characterized as novel potential nonsteroidal inhibitors of rat 5α ...

An ATP7A‐Mediated Endogenous Regulation Bio‐Clay Enzyme Enables Self‐Amplified Copper Accumulation for Immunogenic Pyrop

Advanced Science, EarlyView.
A self‐amplifying bio‐clay nanozyme (Bio‐Clayzyme) disrupts tumor metabolic homeostasis through endogenous copper transporter ATPase (ATP7A) downregulation, enhancing cascade catalysis and triggering immunogenic pyroptosis for effective tumor immunotherapy.

Lipid Metabolic Dysregulation Driven by OSMR Mutations Underlies Amyloidogenesis in Primary Localized Cutaneous Amyloidosis

Advanced Science, EarlyView.
OSMR mutations disrupt STAT5 signaling and AKR1B10‐mediated lipid metabolism, leading to lipid accumulation and protein aggregation in keratinocytes. This metabolic reprogramming drives amyloid deposition in primary localized cutaneous amyloidosis, revealing a mechanistic link between lipid dysregulation and amyloidogenesis.

A Postbiotic‐Inducing Ganoderma applanatum Polysaccharide Repairs the Intestinal Barrier via a Phocaeicola vulgatus ‐ Tridecylic Acid Axis

Advanced Science, EarlyView.
This study identifies GAP2, a bioactive polysaccharide fraction derived from Ganoderma applanatum, as a postbiotic inducer that repairs intestinal barrier damage in a gut microbiota‐dependent manner. GAP2 enriches Phocaeicola vulgatus, which degrades GAP2 and promotes tridecylic acid production, triggering Rho/CDC42 signaling and tight‐junction ...
