Zonated Copper‐Driven Breast Cancer Progression Countered by a Copper‐Depleting Nanoagent for Immune and Metabolic Reprogramming

Advanced Science, EarlyView.
Spatially resolved multiomics reveals that high‐copper zones are closely associated with tumor metastasis, immune‐desert phenotypes, and oxidative‐phosphorylation (OXPHOS)‐dependent proliferation. A targeted bacterial nanovesicle delivering copper‐depleting agents effectively reduces tumor copper levels, inhibits OXPHOS‐dependent tumor growth, and ...

The GABAergic system: a possible component of estrogenic feedback on gonadotropin secretion in rainbow trout (Oncorhynchus mykiss)

Knowledge and Management of Aquatic Ecosystems, 1998
In teleost fish, GTH secretion is controlled by a large number of neuroendocrine factors at the central level and steroid feedback represents an efficient process to synchronize the activity of all the systems involved along the brain-pituitary-gonad ...

Analysis of differential splicing suggests different modes of short-term splicing regulation [PDF]

arXiv, 2016
Motivation: Alternative splicing is an important mechanism in which the regions of pre-mRNAs are differentially joined in order to form different transcript isoforms. Alternative splicing is involved in the regulation of normal physiological functions but also linked to the development of diseases such as cancer.

Targeting Senescence with Apigenin Improves Chemotherapeutic Efficacy and Ameliorates Age‐Related Conditions in Mice

Advanced Science, EarlyView.
As a plant‐derived flavonoid, apigenin directly targets PRDX6 to inhibit its PLA2 activity, blocking HSPA8 activation and disturbing its interactions with ATM and p38MAPK in senescent cells. By dampening wide spectrum expression of the SASP, apigenin prevents loss of tissue homeostasis, improves organ function, and alleviates multiple age‐related ...

Ovarian steroids regulate tachykinin and tachykinin receptor gene expression in the mouse uterus

Reproductive Biology and Endocrinology, 2009
Background In the mouse uterus, pregnancy is accompanied by changes in tachykinin and tachykinin receptor gene expression and in the uterotonic effects of endogenous tachykinins. In this study we have investigated whether changes in tachykinin expression

Role of Testosterone Signaling in Microglia: A Potential Role for Sex‐Related Differences in Alzheimer's Disease

Advanced Science, EarlyView.
Testosterone enhances Aβ‐induced autophagy in microglia via the non‐genomic testosterone receptor GPRC6A, promoting Aβ clearance by suppressing ERK phosphorylation and inhibiting mTOR activation. In male 5xFAD mice, testicular removal reduces microglial autophagy and Aβ clearance, which is restored by testosterone.

Pupylation‐Based Proximity Labeling Unravels a Comprehensive Protein and Phosphoprotein Interactome of the Arabidopsis TOR Complex

Advanced Science, EarlyView.
The target of rapamycin (TOR) complex is a central plant growth regulator. Here, the protein–protein interactions underlying its various functions are mapped by pupylation‐based proximity‐labeling in Arabidopsis, using TOR complex subunits LST8‐1 and RAPTOR1, alongside TOR inhibitor FK506‐binding protein, as baits.

Molecular characterization and expression profile of estrogen receptor subtypes in female hilsa (Tenualosa ilisha)

Frontiers in Marine Science
Hilsa (Tenualosa ilisha), a highly prized edible fish, is consumed by over 250 million people worldwide. Estrogens are essential hormones required during reproduction and bind with estrogen receptors in target organs for biological activity.

Trifunctional Sialylation‐Based SF‐ZIF@NA Hydrogel for Selective Osteoclast Inhibition and Enhanced Bone‐Vessel Regeneration in Osteoporotic Bone Defects

Advanced Science, EarlyView.
This study introduces the SF‐ZIF@NA hydrogel system for osteoporotic bone defect treatment. The hydrogel inhibits osteoclast fusion by removing sialic acid and preserves the anabolic function of precursor osteoclasts (pOCs). It also releases Zn2⁺ in acidic conditions, promoting osteogenesis and angiogenesis.
