Special Issue Information

Dear Colleagues,

Bioinformatics has become a central driver of innovation in modern biotechnology, transforming how we discover, design and develop new therapies, diagnostics and biomaterials. This Special Issue, “The Emerging Role of Bioinformatics in Biotechnology,” aims to showcase cutting-edge computational approaches that bridge data and experiment, accelerating translation from molecules to mechanisms to products.

We invite contributions that highlight how bioinformatics unlocks value from complex biological data, including genomics, transcriptomics, proteomics, structural and imaging datasets. Relevant topics include, but are not limited to, the following: machine learning and AI for biomarker discovery and target identification; computational drug design and virtual screening; molecular dynamics simulations and protein structure–function analysis; integrative pipelines for multi-omics data; bioinformatics for gene and cell therapies; synthetic biology and rational design of biological systems; and data-driven bioprocess optimization.

Both methodological papers and application-focused studies are welcome, as well as reviews that synthesize emerging trends at the interface of computation and biotechnology. The overarching aim of this Special Issue is to illustrate how robust, transparent and scalable bioinformatics solutions can de-risk R&D, enable precision biotechnology, and open new frontiers in health, industry and beyond.

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 250 words) can be sent to the Editorial Office for assessment.

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. BioTech is an international peer-reviewed open access quarterly 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.

Radiotherapy (RT) is one of the main treatments for breast cancer, but response varies between patients. Tumour hypoxia and intrinsic radiosensitivity are major determinants of response to RT. Using TCGA-BRCA, a 563-gene hypoxia meta-signature was built by combining curated hypoxia gene sets from MSigDB with published hypoxia metagenes (Buffa, Winter, Elvidge, Fardin, and related sets). After Cox screening and penalised regression, a simple three-gene hypoxia score (CP, GPC3, STC1) was derived. In parallel, based on DSB-repair factors highlighted by Mladenov et al. as key regulators of intrinsic radiosensitivity, a four-gene radiosensitivity (RS) signature (ATR, RPA2, BLM, MRE11A) was trained using only RT-treated patients. In TCGA, both signatures were prognostic and showed significant interaction with RT status in Cox models. The hypoxia score was strongly associated with worse outcomes in RT-untreated patients, but this effect was much weaker in RT-treated patients (Hypoxia × RT HR = 0.009, p = 0.044). The RS score showed a similarly strong interaction with RT (RS × RT HR = 0.011, p = 0.003). When we combined both signatures into one interaction model, it gave the best performance (C-index = 0.785), and both interaction terms stayed independently significant. The hypoxia score was then validated externally in METABRIC (N = 1979; 1143 events), where it remained associated with overall survival, although more weakly than in TCGA (HR = 1.34, 95% CI: 1.10–1.63; p = 0.0042). Overall, these results suggest that hypoxia and DSB-repair capacity capture two complementary sides of radiosensitivity and RT-modified survival patterns, and they support further prospective testing and validation in independent datasets with strong RT annotation.
