Aims: This study aimed to develop Imatinib Mesylate (IMT)-loaded Poly Lactic-co-Glycolic Acid (PLGA)-D-α-tocopheryl polyethylene glycol succinate (TPGS)- Polyethylene glycol (PEG) hybrid nanoparticles (CSLHNPs) with optimized physicochemical properties for targeted delivery to glioblastoma multiforme.
Background: Glioblastoma multiforme (GBM) is the most destructive type of brain tumor with several complications. Currently, most treatments for drug delivery for this disease face challenges due to the poor blood-brain barrier (BBB) and lack of site-specific delivery.
Phytosomes Loaded with Mastoparan-M Represent a Novel Strategy for Breast Cancer Treatment.

Purpose: Mastoparan-M (Mast-M) has cytotoxic effects on various tumor cells in vitro, including liver cancer and colorectal cancer. However, the anti-tumor mechanism of Mast-M remains unclear and its potential for anti-tumor therapy has not been investigated. Herein, we aimed to develop a novel phytosome formulation loaded with Mast-M and evaluate its efficacy against breast cancer both in vitro and in vivo.

Background: Drug delivery strategies using chitosan nanobubbles (CS-NBs) could be used to reduce drug side effects and improve outcomes in hepatocellular carcinoma (HCC) treatment. To enhance their action, a targeting agent, such as the humanized anti-GPC3 antibody GC33 (condrituzumab), could be attached to their surface. Here, we investigated the use of idarubicin-loaded CS-NBs for HCC treatment and a GC33-derived minibody (that we named 4A1) to enhance CS-NB delivery.

B7-H3, an immunomodulatory protein overexpressed in many cancers, is associated with tumor aggressiveness and poor prognosis, making it a crucial target for imaging to elucidate its role in cancer progression and guide therapeutic interventions. This study employed PET imaging to investigate the in vivo delivery and pharmacokinetics of two anti-B7-H3 antibodies, Ab-1 and Ab-2, in mouse xenograft models with varying B7-H3 expression levels. The antibodies were radiolabeled with [Zr]Zr and evaluated through PET imaging, biodistribution studies, and in vitro assays to assess binding, tumor uptake, and retention.

Department of Nuclear Medicine and Molecular Imaging, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.
Purpose: This preclinical study explored the feasibility of assessing P-glycoprotein (P-gp) function in both brain and gastrointestinal (GI) tract of rats using positron emission tomography (PET) following oral administration of [F]MC225. Different oral administration protocols were evaluated, and radioactivity uptake was compared with uptake following intravenous administration.
Procedures: Twelve male Wistar rats were divided into four groups and subjected to intravenous or oral [F]MC225 administration protocols: G (intravenous route), G (oral administration without fasting), G (oral administration with fasting), and G (oral administration with fasting following administration of the P-gp inhibitor tariquidar).
