PDZK1‐ULK1 Axis Triggers Lipophagy to Inhibit Tumor Progression and Sunitinib Resistance in Clear Cell Renal Cell Carcinoma

Advanced Science, EarlyView.
This study reveals that PDZK1 loss impairs ULK1‐mediated lipophagy, driving lipid droplet accumulation and sunitinib resistance in clear cell renal cell carcinoma. PDZK1 inhibits LEF1 nuclear translocation, enhancing ULK1 transcription. Pharmacological ULK1 activation resensitizes resistant tumors to sunitinib.

TriCON: A Carbon‐Based Triple‐Modal Nanoplatform for Pancreatic Cancer Therapy

Advanced Science, EarlyView.
We developed TriCON, a triple‐modality nanotherapeutic platform, to treat pancreatic ductal adenocarcinoma (PDAC) by synergizing gene editing, chemotherapy, and immunotherapy. TriCON utilizes CRISPR/Cas9 to target the poliovirus receptor (PVR), combined with nano‐encapsulated doxorubicin and checkpoint blockade. This approach achieved significant tumor

Metabolic Reprogramming of T Cells by Dual UCP2 and IL‐17 Blockade Enhances Immunity Against Pancreatic Cancer

Advanced Science, EarlyView.
This study demonstrates that dual UCP2/IL‐17 blockade reprograms T‐cell metabolism to overcome PDAC immunosuppression. Genipin‐mediated UCP2 inhibition enhances CD8⁺ T‐cell IFN‐γ via IL‐12R/STAT4/mTOR signaling and mitochondrial OXPHOS. Combined IL‐17 depletion amplifies Tc1/Th1 responses, reduces MDSCs, and prolongs survival in PDAC models ...

The distribution of ATP within tomato (Lycopersicon esculentum Mill.) embryos correlates with germination whee as total ATP concentration does not [PDF]

The distribution of ATP in tomato seeds was visualized by monitoring the luminescence of frozen sections on top of a gel containing all the components of the luciferase reaction, but excluding ATP.

Fibrates Inhibit PLTP‐induced M2 Macrophage Infiltration and Increase the Sensitivity of Hepatocellular Carcinoma to ICIs

Advanced Science, EarlyView.
Phospholipid transfer protein(PLTP) plays a critical role in forming a complex with kinase A (AURKA) and P65. This interaction facilitates phosphorylation of P65 at Ser536, leading to the activation of the NF‐κB signaling pathway. Ultimately, this leads to the upregulation of downstream cytokines, including IL‐6, IL‐8, and CSF‐1, which promotes M2 ...

Early Detection of Cell Death Using Transmembrane Water Exchange Magnetic Resonance Imaging

Advanced Science, EarlyView.
Cell death is important in both the development and treatment of cancer. In this study, it is demonstrated for the first time that a specific measurement of the transmembrane water exchange rate using magnetic resonance imaging can be used as an early marker of cell death in mammalian cells, in animals and in human patients. Abstract Cell death plays a

De novo variants disturbing the transactivation capacity of POU3F3 cause a characteristic neurodevelopmental disorder

, 2019
POU3F3, also referred to as Brain-1, is a well-known transcription factor involved in the development of the central nervous system, but it has not previously been associated with a neurodevelopmental disorder.

In vivo dual substrate bioluminescent imaging.

Journal of visualized experiments : JoVE, 2011
Our understanding of how and when breast cancer cells transit from established primary tumors to metastatic sites has increased at an exceptional rate since the advent of in vivo bioluminescent imaging technologies. Indeed, the ability to locate and quantify tumor growth longitudinally in a single cohort of animals to completion of the study as opposed
