Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

open access: yesAdvanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

No evidence for oncogenic mutations in guanine nucleotide-binding proteins of human adrenocortical neoplasms [PDF]

open access: yes, 1933
G-Proteins are membrane-bound heterotrimeric polypeptides that couple receptor signals to second messenger systems such as cAMP. Recently, point mutations at 2 codons of the highly preserved alpha-chain of Gs, the adenyl cyclase-stimulating G-protein ...

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

open access: yesAdvanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,

Dysfunctional TRIM31 of POMC Neurons Provokes Hypothalamic Injury and Peripheral Metabolic Disorder under Long‐Term Fine Particulate Matter Exposure

open access: yesAdvanced Science, EarlyView.
Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...

Single‐Cell Dissection Reveals Immune Dysregulation After CD5 or CD7‐Directed Chimeric Antigen Receptor T‐Cell Therapy

open access: yesAdvanced Science, EarlyView.
Single‐cell RNA/TCR/BCR sequencing reveals that 5CAR therapy in T‐ALL induces T‐cell exhaustion, reduces EBV‐associated TCRs, lowers TCR/BCR diversity, and increases NK/DC/monocyte activation and function. In contrast, 7CAR therapy reduces multiple pathogen‐associated TCRs, enhances NK cell activation and function, decreases monocyte activation, and ...

Bioprinting of Microtissues Within Mechanically Tunable Support Baths to Engineer Anisotropic Musculoskeletal Tissues

open access: yesAdvanced Science, EarlyView.
This study presents a novel 4D bioprinting platform for engineering biomimetic musculoskeletal grafts. By tuning the mechanical properties of support baths, we enhance tissue fusion, collagen alignment, and cell differentiation. Using this strategy, we successfully fabricate scaled‐up, anisotropic tissues such as meniscus, articular cartilage, and ...

Pancreatic endocrine and exocrine signaling and crosstalk in physiological and pathological status

open access: yesSignal Transduction and Targeted Therapy
The pancreas, an organ with dual functions, regulates blood glucose levels through the endocrine system by secreting hormones such as insulin and glucagon. It also aids digestion through the exocrine system by secreting digestive enzymes.
