Filter by:The investigators designed and synthesized a novel fibroblast activation protein (FAP) ligand (DOTA-GPFAPI-04) by assembling three functional moieties: a quinoline-based FAP inhibitor for specifically targeting FAP, a FAP substrate Gly-Pro as a linker for increasing the FAP protein interaction, and a 2,2',2",2‴-(1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrayl)tetraacetic acid (DOTA) chelator for radiolabeling with different radionuclides. Molecular docking studies investigated the FAP targeting ability of DOTA-GPFAPI-04. DOTA-GPFAPI-04 was then radiolabeled with 68Ga to give 68Ga-DOTA-GPFAPI-04 for positron emission tomography (PET) imaging. The investigators found that the 68Ga-DOTA-GPFAPI-04 has high stability, targeted specificity, and longer retention time. The tumor-to-muscle (T/M) ratio for 68Ga-DOTA-GPFAPI-04 reached 9.15.

Many human diseases are characterized by their ability to alter existing metabolic pathways and interrupt cellular processes. Cancer exploits the Warburg effect and utilizes greater glucose than normal cells and within this process uses anaerobic respiration, leading to increased conversion of pyruvate to lactate. This can be exploited by hyperpolarized imaging. Hyperpolarized 13C MRI imaging is an approach that utilizes a stable isotope of Carbon (13C) linked to pyruvate. MRI spectroscopy is used in conjunction with hyperpolarized 13C pyruvate in order to temporally detect pyruvate and its conversion to lactate in-vivo, in order to visualize downstream metabolic (glycolytic) activity secondary to the Warburg effect, which should be useful in detecting and characterizing tumors of various types. Hyperpolarized 13C pyruvate MR imaging has not been tested in most cancers. In this preliminary survey, we will test the hypothesis that hyperpolarized 13C pyruvate MR imaging can be used to image various cancers.
This study is a clinical trial of prospective, two-center, single-arm objective performance criteria. This trial will be conducted in 2 clinical trial sites with a total of 47 subjects enrolled. All of subjects will be treated with radiation therapy using the medical device Varian ProBeam Proton Therapy System (ProBeam), aim to compare the data with objective performance criteria (OPC) to evaluate the effectiveness and safety of ProBeam radiotherapy system for oncology patients, providing a clinical basis for the medical device registration.
Primary Objectives are to determine the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of ZN-c3 and ZN-c3 and bevacizumab or ZN-c3 and bevacizumab plus pembrolizumab in metastatic CCNE1 amplified and TP53 mutant solid tumors as well to evaluate antitumor activity of ZN-c3 and bevacizumab or ZN-c3 and bevacizumab plus pembrolizumab in metastatic CCNE1 amplified and TP53 mutant solid tumors.
We will conduct a two-phase study. The first phase is to adapt and develop an active video game (AVG)-centered lifestyle physical activity (PA) intervention (POWER UP) for adolescents and young adults (AYA) with central nervous system tumors. The second phase is to test the feasibility and preliminary efficacy of a 12-week virtually delivered, group-based active video game-centered lifestyle physical activity intervention on function and quality of life in AYAs (aged 15-39) who are ≤1-year post-surgery for a central nervous system tumor. This population is at very high-risk for steep functional decline.
Primary objective of this study is to identify and describe the clinico-biological and molecular characteristics of tumors with somatic POLE (Polymerase ɛ)/POLD1 mutation identified by molecular biology platforms for all stages and primary sites combined
A Phase 2 multi-center open-label basket trial of nab-sirolimus for adult and adolescent patients with malignant solid tumors harboring pathogenic inactivating alterations in TSC1 or TSC2 genes
Fluorescence is one of the most commonly used research and detection techniques in the field of biomedical science. The characteristics of fluorescent probe directly affect the performance and application of fluorescence analysis and imaging. Aggregation-Caused Quenching has limited the application of traditional fluorescent probes to some extent. This project intends to systematically evaluate the detection efficiency of new methods through the detection of biomarkers in clinical samples and the comparison with the detection methods of traditional biomarkers, so as to provide theoretical and experimental basis for the establishment of fast and simple biomarker detection technologies with new biological probes.
