uPAR Immuno-PET in Pancreatic Cancer, Aging, and Chemotherapy-Induced Senescence.

Identifying cancer therapy resistance is a key time-saving tool for physicians. Part of chemotherapy resistance includes senescence, a persistent state without cell division or cell death. Chemically inducing senescence with the combination of trametinib and palbociclib (TP) yields several tumorigenic and prometastatic factors in pancreatic cancer models with many potential antibody-based targets.

Pb-Pretargeted Theranostics for Pancreatic Cancer.

Although pancreatic ductal adenocarcinoma (PDAC) is associated with limited treatment options and poor patient outcomes, targeted α-particle therapy (TAT) represents a promising development in the field. TAT shows potential in treating metastatic cancers, including those that have become resistant to conventional treatments. Among the most auspicious radionuclides stands the in vivo α-generator Pb.

PET Imaging of Acidic Tumor Environment With Zr-labeled pHLIP Probes.

Acidosis of the tumor microenvironment is a hallmark of tumor progression and has emerged as an essential biomarker for cancer diagnosis, prognosis, and evaluation of treatment response. A tool for quantitatively visualizing the acidic tumor environment could significantly advance our understanding of the behavior of aggressive tumors, improving patient management and outcomes. Zr-labeled pH-low insertion peptides (pHLIP) are a class of radiopharmaceutical imaging probes for the analysis of acidic tumor microenvironments positron emission tomography (PET).
