Special Issue Information

Dear Colleagues,

Cancer cells reprogram their metabolism by consuming high levels of glucose and some nonessential amino acids (like glutamine, serine, and others), producing reactive oxygen species, and potentiating the synthesis of nucleotides, fatty acids, and lipids. The application of metabolomic profiling to biological fluids and matrices has recently emerged as a powerful and reliable tool for identifying novel biomarkers to improve early diagnosis and prognostication and for predicting the response of cancer patients to treatment. The large-scale study of metabolites in biological samples, such as cells, tissues, or biological fluids, takes advantage of several technologies, like 1H-nuclear magnetic resonance (1H-NMR) spectroscopy; gas chromatography–mass spectrometry (GC-MS), liquid chromatography–mass spectrometry (LC-MS), Fourier-transform infrared spectroscopy (FT-IR), and vibrational and Raman spectroscopy.

The aim of this Special Issue is to present the latest research and new studies based on metabolomics approaches applied to cancer research on different biological matrices such as cancer cells, tissues, and biological fluids. Pure clinical studies would not suitable for our Special Issue; however, clinical submissions with biomolecular/metabolomic experiments will be welcome.

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 submissions that pass pre-check are 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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

In this work, the HR MAS NMR (high-resolution magic-angle spinning nuclear magnetic resonance) spectroscopy technique was combined with standard histological examinations to investigate the metabolic features of high-grade serous ovarian cancer (HGSOC) with a special focus on the relation between a metabolic profile and a cancer cell fraction. The studied group consisted of 44 patients with HGSOC and 18 patients with benign ovarian tumors. Normal ovarian tissue was also excised from 13 control patients. The metabolic profiles of 138 tissue specimens were acquired on a Bruker Avance III 400 MHz spectrometer. The NMR spectra of the HGSOC samples could be discriminated from those acquired from the non-transformed tissue and were shown to depend on tumor purity. The most important features that differentiate the samples with a high fraction of cancer cells from the samples containing mainly fibrotic stroma are the increased intensities in the spectral regions corresponding to phosphocholine/glycerophosphocholine, phosphoethanolamine/serine, threonine, uridine nucleotides and/or uridine diphosphate (UDP) nucleotide sugars. Higher levels of glutamine, glutamate, acetate, lysine, alanine, leucine and isoleucine were detected in the desmoplastic stroma within the HGSOC lesions compared to the stroma of benign tumors. The HR MAS NMR analysis of the metabolic composition of the epithelial and stromal compartments within HGSOC contributes to a better understanding of the disease’s biology. Full article
