The Study Of Serum Prostate Specific Antigen And Phosphatase Isoenzymes Activity As Diagnostic Parameters In Patients With Prostate Cancer In Nigeria

open access: yesOnline Journal of Health & Allied Sciences, 2004
Serum activities of Acid Phosphatase (ACP) and Prostatic Acid Phosphatase (PAP) are still employed in most hospitals in Nigeria for the diagnosis of prostate cancer, because of lack of resources for prostate specific antigen (PSA) assay.

Age‐Related Lamin B1 Deficiency Activates SLC7A11‐Dependent Disulfidptosis to Impair Osteogenesis via Intercepting Mitochondrial Fission

open access: yesAdvanced Science, EarlyView.
This study reveals that age‐related LMNB1 deficiency in mesenchymal stem cells epigenetically upregulates SLC7A11, triggering actin disulfidptosis and mitochondrial dysfunction. This cascade impairs bone formation in senile osteoporosis. Furthermore, researchers identified the FDA‐approved drug naldemedine as a targeted SLC7A11 inhibitor to reverse ...

A Novel Reactive Oxygen Species‐Responsive Bone‐Targeted Nanoplatform Based on Cloperastine Attenuates Ovariectomy‐Induced Bone Loss by Inhibiting Osteoclast Oxidative Phosphorylation

open access: yesAdvanced Science, EarlyView.
Cloperastine suppresses osteoclastogenesis by inhibiting PGC1β‐mediated oxidative phosphorylation. Its incorporation into a ROS‐responsive, Asp8‐modified nanoplatform enhances skeletal accumulation. The resulting Clo/Asp8‐PMK‐MCs combine cloperastine‐mediated antiresorptive activity with carrier‐mediated osteogenic activity to attenuate OVX‐induced ...

Intratumoral Fusogenic Outer Membrane Vesicles Enhance Antitumor Immunity Through Tumor MHC‐I Upregulation and Tumor Bacterization

open access: yesAdvanced Science, EarlyView.
Tumor bacterization by fusogenic outer membrane vesicles enhances microbial‐like recognition of tumor cells while activating the TLR4–NF‐κB–NLRC5 axis to upregulate MHC class I expression. By simultaneously strengthening APC sensing and T‐cell recognition, this strategy breaks tumor immune invisibility and promotes more effective antitumor immune ...

A Fish MDA5 Integrates Canonical RIG‐I and MDA5 Ligand Recognition

open access: yesAdvanced Science, EarlyView.
These results show that the large yellow croaker lacks RIG‐I, yet its MDA5 senses both 5′ppp‐dsRNA and long dsRNA. A flexible RNA‐capping loop in the MDA5 C‐terminal domain enables two ligand‐binding modes. This dual recognition signals through MAVS–STING–TBK1/IRF3 and induces type I interferons, revealing unexpected plasticity in vertebrate antiviral ...

A Fluorogenic Cysteine‐Tetrapeptide Tagging Strategy for Nonperturbative Protein Labeling and Protein–Ligand Interaction Tracking

open access: yesAdvanced Science, EarlyView.
A compact Phe‐Cys‐Pro‐Phe (FCPF) tag and an environment‐sensitive SBD‐Cl‐derived probe form a sequence‐selective fluorogenic pair for wash‐free live‐cell protein imaging. This minimally perturbing chemistry allows flexible insertion at termini or loops, produces strong fluorescence upon local microenvironment confinement, supports FRET‐assisted ...

Polyphosphate Copper Nanospheres Drive Mitochondrial Metabolic Reprogramming via Calcium Phase Separation for Self‐Sensitizing Cuproptosis

open access: yesAdvanced Science, EarlyView.
This study developed polyphosphate (polyP)‐based nanostructures that enable calcium‐mediated metabolic reprogramming via liquid–liquid phase separation (LLPS). Released polyP undergoes LLPS with Ca2+, suppressing glycolytic flux and enhancing mitochondrial metabolism effectively.
