Abstract
Neuroendocrine carcinomas, such as neuroendocrine prostate cancer and small-cell lung cancer, commonly have a poor prognosis and limited therapeutic options. We report that ubiquitin carboxy-terminal hydrolase L1 (UCHL1), a deubiquitinating enzyme, is elevated in tissues and plasma from patients with neuroendocrine carcinomas. Loss of UCHL1 decreases tumor growth and inhibits metastasis of these malignancies. UCHL1 maintains neuroendocrine differentiation and promotes cancer progression by regulating nucleoporin, POM121, and p53. UCHL1 binds, deubiquitinates, and stabilizes POM121 to regulate POM121-associated nuclear transport of E2F1 and c-MYC. Treatment with the UCHL1 inhibitor LDN-57444 slows tumor growth and metastasis across neuroendocrine carcinomas. The combination of UCHL1 inhibitors with cisplatin, the standard of care used for neuroendocrine carcinomas, significantly delays tumor growth in pre-clinical settings. Our study reveals mechanisms of UCHL1 function in regulating the progression of neuroendocrine carcinomas and identifies UCHL1 as a therapeutic target and potential molecular indicator for diagnosing and monitoring treatment responses in these malignancies.

Abstract
Abstract
Background: Sequencing of immune checkpoint inhibitors (ICI) and external beam radiation therapy (EBRT) for cancer treatment has been studied, but the optimal sequencing has yet to be determined. While some studies have noted therapeutic advantages of priming the tumor immune microenvironment with EBRT prior to ICI, others have described the benefit of modulating the tumor infiltrating lymphocyte (TIL) population with ICI before EBRT. Targeted radionuclide therapy (TRT) approaches allow investigation of how irradiation by a tumor-targeted radionuclide and differences in emission type, linear energy transfer, and dose rate affect optimal timing of ICI administration. NM600 is an alkylphosphocholine analog selectively taken up by tumors capable of chelating numerous radionuclides for comparative studies.
Objective: We use two immunologically cold tumor models, MOC2 head and neck squamous cell carcinoma and B78 melanoma, to describe the influence of dose rate on type I interferon (IFN1) signaling and the effect of ICI and 90Y-, 177Lu-, and 225Ac-NM600 TRT sequences on tumor response.
Methods: 90Y, 177Lu, or 225Ac were added to culture media in activities estimated using GEANT4 Monte Carlo to deliver 12 Gy to the cell monolayer. qPCR was performed on cDNA from cells irradiated with EBRT, 90Y, 177Lu, or 225Ac, and harvested on days 1, 3, or 7. In vivo dosimetry was performed using the Monte Carlo-based RAPID platform utilizing serial PET/CT or SPECT/CT imaging and/or longitudinal biodistribution. Differences over time (days 4, 7, 14, 21, 28 after RT) in TIL and systemic immune cell populations were measured by flow cytometry following no treatment, 12 Gy EBRT, or 90Y-, 177Lu-, or 225Ac-NM600 in MOC2 tumors. Mice bearing B78 tumors received 1.5 Gy 90Y-, 177Lu-, or 225Ac-NM600, or no radiation on day 1 +/- ICI (anti-CTLA4 + anti-PDL1) on days -3/0/3 (early), 4/7/10 (middle), or 11/14/17 (late). Mice were monitored for tumor growth and survival.
Results: TRT and EBRT induced IFN1 responses in MOC2 cells. MOC2 cells treated every 24h with EBRT-matched 90Y/225Ac dose rates led to upregulation of IFN1-associated Ifnb1 and Mx1, mimicking radionuclide-induced responses. Increased tumor CD8/Treg ratios and decreased Tregs were observed at day 7 following all RT forms in MOC2 tumors. Long half-life 225Ac-NM600 (90Y: 65h; 177Lu: 161h; 225Ac: 240h) induced similar TIL changes at day 21. For 1.5 Gy 90Y-, 177Lu-, and 225Ac-NM600, B78 tumor growth delay and statistically significant overall survival benefit over respective TRT monotherapy and control groups was observed with early (day -3/0/3) dual ICI administration.
Conclusions: These studies demonstrate novel immunomodulatory effects of α- and β- emitting TRT and the capacity to achieve substantial antitumor responses with appropriate TRT + ICI sequencing. These results may inform clinical trial design of TRT + ICI regimens for patients with metastatic cancers.

Abstract
PURPOSE The lack of effective molecular biomarkers to monitor idiopathic pulmonary fibrosis (IPF) activity or treatment response remains an unmet clinical need. Herein, we determined the utility of fibroblast activation protein inhibitor for positron emission tomography (FAPI PET) imaging in a mouse model of pulmonary fibrosis. METHODS Pulmonary fibrosis was induced by intratracheal administration of bleomycin (1 U/kg) while intratracheal saline was administered to control mice. Subgroups from each cohort (n = 3-5) underwent dynamic 1 h PET/CT after intravenously injecting FAPI-46 radiolabeled with gallium-68 ([68 Ga]Ga-FAPI-46) at 7 days and 14 days following disease induction. Animals were sacrificed following imaging for ex vivo gamma counting and histologic correlation. [68 Ga]Ga-FAPI-46 uptake was quantified and reported as percent injected activity per cc (%IA/cc) or percent injected activity (%IA). Lung CT density in Hounsfield units (HU) was also correlated with histologic examinations of lung fibrosis. RESULTS CT only detected differences in the fibrotic response at 14 days post-bleomycin administration. [68 Ga]Ga-FAPI-46 lung uptake was significantly higher in the bleomycin group than in control subjects at 7 days and 14 days. Significantly (P = 0.0012) increased [68 Ga]Ga-FAPI-46 lung uptake in the bleomycin groups at 14 days (1.01 ± 0.12%IA/cc) vs. 7 days (0.33 ± 0.09%IA/cc) at 60 min post-injection of the tracer was observed. These findings were consistent with an increase in both fibrinogenesis and FAP expression as seen in histology. CONCLUSION CT was unable to assess disease activity in a murine model of IPF. Conversely, FAPI PET detected both the presence and activity of lung fibrogenesis, making it a promising tool for assessing early disease activity and evaluating the efficacy of therapeutic interventions in lung fibrosis patients.

Abstract
There is a clinically unmet need for effective treatments for triple-negative breast cancer (TNBC), as it remains the most aggressive subtype of breast cancer. Herein, we demonstrate a promising strategy using a tumor-targeting alkylphosphocholine (NM600) for targeted radionuclide therapy of TNBC. Methods: NM600 was radiolabeled with 86Y for PET imaging and 177Lu for targeted radionuclide therapy. 86Y-NM600 PET imaging was performed on female BALB/C mice bearing syngeneic 4T07 (nonmetastatic) and 4T1 (metastatic) TNBC tumor grafts (n = 3–5). Quantitative data derived from a PET-image region-of-interest analysis, which was corroborated by ex vivo biodistribution, were used to estimate the dosimetry of 177Lu-NM600 treatments. Weight measurement, complete blood counts, and histopathology analysis were performed to determine 177Lu-NM600 toxicity in naïve BALB/C mice administered 9.25 or 18.5 MBq. Groups of mice bearing 4T07 or 4T1 grafts (n = 5–6) received excipient or 9.25 or 18.5 MBq of 177Lu-NM600 as a single or fractionated schedule, and tumor growth and overall survival were monitored. Results: Excellent tumor targeting and rapid normal-tissue clearance of 86Y-NM600 were noted in both 4T07 and 4T1 murine models. Ex vivo biodistribution corroborated the accuracy of the PET data and validated 86Y-NM600 as a surrogate for 177Lu-NM600. 177Lu-NM600 dosimetry showed absorbed doses of 2.04 ± 0.32 and 1.68 ± 0.06 Gy/MBq to 4T07 and 4T1 tumors, respectively, which were larger than those delivered to liver (1.28 ± 0.09 Gy/MBq) and to bone marrow (0.31 ± 0.05 Gy/MBq). The 177Lu-NM600 injected activities used for treatment were well tolerated and resulted in significant tumor growth inhibition and prolonged overall survival in both tested TNBC models. A complete response was attained in 60% of treated mice bearing 4T07 grafts. Conclusion: Overall, our results suggest that 177Lu-NM600 targeted radionuclide therapy has potential for TNBC and merits further exploration in a clinical setting.
