In vitro and in vivo application of radiolabeled gastrin-releasing peptide receptor ligands in breast cancer.
UNLABELLED Breast cancer (BC) consists of multiple subtypes defined by various molecular characteristics, for instance, estrogen receptor (ER) expression. Methods for visualizing BC include mammography, MR imaging, ultrasound, and nuclear medicine-based methods such as (99m)Tc-sestamibi and (18)F-FDG PET, unfortunately all lacking specificity. Peptide receptor scintigraphy and peptide receptor ...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولGastrin-releasing Peptide Receptor Imaging in Breast Cancer Using the Receptor Antagonist 68Ga-RM2 And PET
INTRODUCTION The gastrin-releasing peptide receptor (GRPR) is overexpressed in breast cancer. The present study evaluates GRPR imaging as a novel imaging modality in breast cancer by employing positron emission tomography (PET) and the GRPR antagonist (68)Ga-RM2. METHODS Fifteen female patients with biopsy confirmed primary breast carcinoma (3 bilateral tumors; median clinical stage IIB) unde...
متن کاملGastrin releasing peptide and gastrin releasing peptide receptor expression in gastrointestinal carcinoid tumours.
AIMS To establish whether gastrin releasing peptide (GRP) and the GRP receptor (GRPR) are expressed together in gastrointestinal carcinoid tumours. METHODS Twenty six carcinoid tumours from the stomach, small intestine, appendix, and colorectum were investigated by immunohistochemistry for GRP and GRPR. RESULTS GRP was detected in nine of 19 tumours and GRPR in 22 of 26. Coexpression of bot...
متن کاملGastrin-releasing peptide receptor in breast cancer mediates cellular migration and interleukin-8 expression.
BACKGROUND Breast cancers aberrantly express gastrin-releasing peptide (GRP) hormone and its cognate receptor, gastrin-releasing peptide receptor (GRP-R). Experimental evidence suggests that bombesin (BBS), the pharmacological homologue of GRP, promotes breast cancer growth and progression. The contribution of GRP-R to other poor prognostic indicators in breast cancer, such as the expression of...
