   Sammanfattning : Targeted radiotherapy of cancer intends to selectively deliver cytotoxic radionuclides to tumor cells. Affinity proteins of various kinds are explored for this task, and depending on the affinity protein used, different challenges arise. LÄS MER

3. 2. Prostate cancer theranostics using GRPR antagonist RM26

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastrin-releasing peptide receptor GRPR ; Bombesin; Prostate-specific membrane antigen PSMA ; Antagonist; Radionuclide molecular imaging; Theranostics; Peptide receptor radionuclide therapy PRRT .;

   Sammanfattning : The malignant transformation of cells is often associated with an alteration of their molecular phenotype, resulting in overexpression of several cell surface proteins. Gastrin-releasing peptide receptor (GRPR) and prostate-specific membrane antigen (PSMA) are examples of such pro-teins that are expressed at a high density in prostate cancer. LÄS MER

4. 3. Theranostic Targeting of GRPR and PSMA in Prostate Cancer

   Författare :Ayman Abouzayed; Anna Orlova; Ulrika Rosenström; Anzhelika Vorobyeva; Bogdan Mitran; Cristina Müller; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; gastrin-releasing peptide receptor GRPR ; prostate-specific membrane antigen PSMA ; nuclear medicine; molecular imaging; radiotracers; theranostics; Farmaceutisk vetenskap; Pharmaceutical Science; Oncology; Onkologi;

   Sammanfattning : This thesis is based on five original articles that investigated the theranostics of prostate cancer by gastrin-releasing peptide receptor (GRPR) and prostate-specific membrane antigen (PSMA) targeting. GRPR and PSMA are two extensively evaluated prostate cancer cell markers due to their overexpression in the majority of prostate cancer samples. LÄS MER

5. 4. Bombesin Antagonists for Targeting Gastrin-Releasing Peptide Receptor-Positive Tumors : Design, Synthesis, Preclinical Evaluation and Optimization of Imaging Agents

   Författare :Zohreh Varasteh; Anna Orlova; Roger Schibli; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bombesin; Gastrin-releasing peptide receptor GRPR ; Antagonist; Radionuclide molecular imaging;

   Sammanfattning : This thesis is focused on the development, preclinical evaluation, and optimization of radiotracers for the detection of gastrin-releasing peptide receptor (GRPR)-expressing tumors. The work is divided into three distinct parts: (1) the development of bombesin (BN) antagonist (RM26)-based imaging radiotracers for the detection of GRPR-expressing tumors using different positron emission tomography (PET) and single photon emission computed tomography (SPECT) radionuclides (68Ga, 18F and 111In), (2) the establishment of a method to monitor the ligand-G protein-coupled receptor (GPCR) interaction in real time without requiring purification and stabilization of the receptors, and (3) the evaluation of radiopeptide structure-related factors (length of mini-PEG linker and composition of chelator for metal labeling) affecting the in vitro and in vivo characteristics of RM26-based tracers.
