Special Issue Information

Dear Colleagues,

The evolution of molecular imaging over the past two decades has ushered in new approaches to detect, treat, and monitor the treatment response of pathophysiologic conditions in animal models of human diseases. In particular, the application of these methods to cancer imaging and therapy holds great promise in improving the accuracy of cancer detection and the efficacy of targeted therapies, as well as reporting the functional status and state of the disease. As a result, new molecular imaging probes and methods are expected to provide diagnostic information beyond what is currently available in clinics. Thus, in addition to reporting the presence of cancer, emerging molecular imaging probes could also determine tumor viability, type, stage, heterogeneity, and potential response to treatment. The goal of this Special Issue is to assemble pertinent research papers, perspectives, and concise reviews that illustrate how molecular imaging can overcome current challenges in cancer detection, staging, and response to therapy. Manuscripts that cover the diverse molecular imaging platforms are welcome. These include optical, nuclear, ultrasonic, magnetic resonance, and multimodal imaging probes and methods. Examples of research work that have advanced from bench to bedside are also encouraged, including the challenges and opportunities in obtaining regulatory approval to use molecule probes in human patients.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We aim to characterize the metabolic changes associated with early response to radiation therapy in a prostate cancer mouse model by 2-deoxy-2-[18F]fluoro-d-glucose ([18F]FDG) and [11C]acetate ([11C]ACT) positron emission tomography, with nuclear magnetic resonance (NMR) metabolomics corroboration. [18F]FDG and [11C]ACT PET were performed before and following irradiation (RT, 15Gy) for transgenic adenocarcinoma of mouse prostate xenografts. The underlying metabolomics alterations of tumor tissues were analyzed by using ex vivo NMR. The [18F]FDG total lesion glucose (TLG) of the tumor significant increased in the RT group at Days 1 and 3 post-irradiation, compared with the non-RT group (p < 0.05). The [11C]ACT maximum standard uptake value (SUVmax) in RT (0.83 ± 0.02) and non-RT groups (0.85 ± 0.07) were not significantly different (p > 0.05). The ex vivo NMR analysis showed a 1.70-fold increase in glucose and a 1.2-fold increase in acetate in the RT group at Day 3 post-irradiation (p < 0.05). Concordantly, the expressions of cytoplasmic acetyl-CoA synthetase in the irradiated tumors was overexpressed at Day 3 post-irradiation (p < 0.05). Therefore, TLG of [18F]FDG in vivo PET images can map early treatment response following irradiation and be a promising prognostic indicator in a longitudinal preclinical study. The underlying metabolic alterations was not reflected by the [11C]ACT PET. Full article
