Fibroblast activation protein (FAP), which is overexpressed in cancer-associated fibroblasts (CAFs), represents a promising target for cancer diagnosis and therapy. Hypoxia is a common feature of solid tumors. A bivalent agent, DOTA-NI-FAPI-04 (), was developed by incorporating hypoxia-sensitive nitroimidazole (NI) into the FAP-targeting agent FAPI-04.

- A study was conducted to compare a new GLP-1R-targeted PET agent, 68 Ga-HBED-CC-exendin-4, with an older version, 68 Ga-NOTA-exendin-4, for locating insulinoma in patients with hyperinsulinemic hypoglycemia.
- Both agents demonstrated 100% sensitivity, but 68 Ga-HBED-CC-exendin-4 had a lower tumor uptake value compared to 68 Ga-NOTA-exendin-4, although both maintained similar tumor-to-background ratios.
- The new agent also showed a significant reduction in renal accumulation, potentially enhancing the detection of tumors located near the kidney.
Article Synopsis
- Bisphosphonates are crucial for treating bone tumors by preventing bone loss; this study explores the effectiveness of a new bisphosphonate, [Lu]Lu-P15-073, in radioligand therapy for bone metastases.
- Ten patients aged 35 to 75 with bone metastases received a single dose of [Lu]Lu-P15-073, showing rapid accumulation in tumors and minimal impact on other organs, while demonstrating safety through blood tests and pain assessments.
- The results indicate that the treatment was well-tolerated, significantly reduced pain in most patients, and suggests that [Lu]Lu-P15-073 could be a promising option for managing bone metastases.
Article Synopsis
- D6-[F]FP-(+)-DTBZ is a new imaging agent designed for PET scans that helps diagnose Parkinson's disease (PD) by tracking VMAT2 transporters in the brain.
- In a study, this radioligand demonstrated efficient production, high purity, and distinct uptake in brain regions associated with PD, showing a greater effectiveness compared to its non-deuterated counterpart.
- The findings suggest that D6-[F]FP-(+)-DTBZ could serve as a safer, more effective tool for monitoring VMAT2 levels in monoamine neurons, potentially improving PD diagnosis.
Functional inversion of circadian regulator REV-ERBα leads to tumorigenic gene reprogramming.

Article Synopsis
- Dysregulation of circadian rhythm (CR) is linked to cancer, with the study highlighting a major shift in the function of the CR regulator REV-ERBα in tumors.
- REV-ERBα transitions from a gene repressor in normal tissues to a gene activator in cancer, activating many tumor-related signaling pathways through its partnership with other proteins like FOXA1.
- Targeting REV-ERBα with the drug SR8278 can reduce its function and, when combined with BRD4 inhibitors, effectively suppress tumor growth by disrupting tumorigenic gene programs.
