Special Issue Information

Dear Colleagues,

The human microbiome, a diverse ecosystem of bacteria, viruses, fungi, and protozoa, colonizes various body sites and plays a crucial role in maintaining homeostasis and driving disease-related phenomena. Microbiota regulates host gene expression through complex bidirectional interactions occurring in both cellular and extracellular environments. Microbiome-derived signals (such as transcripts, metabolites, enzymes, and changes in pH) are detected by host cells via extracellular receptors or following intracellular entry. These signals influence key regulatory mechanisms, including transcription factor (TF) binding, DNA methylation, chromatin accessibility, transcription initiation, and alternative splicing, ultimately leading to changes in gene and protein expressions. Conversely, host-derived proteins affect microbial growth and gene expressions, creating a dynamic feedback loop.

This Special Issue invites research studies that expand the knowledge of the already known microbiota–host axis, but more importantly, it favors research studies that explore new relationships. Given the ability of microbiota to influence host gene expression independent of chromatin accessibility (e.g. via epigenetic modifications or changes in the TF expression), studies exploring this are especially valued. We welcome original studies in the form of in silico, in vitro, and in vivo investigations, with exploratory and bioinformatics-based approaches being encouraged in cases of conceptually novel relationships. Papers that fall outside these criteria will also be considered.

We look forward to receiving your contributions.

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. 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.

The AP-2 family is a group of key regulators in cancer, yet their relationship with intratumoral microbes remains undefined. The present pan-cancer workflow leveraged TCGA transcriptomic data to correlate expression of AP-2 representatives with bacterial abundance on the genus and species level, followed by cohort-specific survival modeling, clinical profiling, differential expression, weighted co-expression analysis, and chromatin proximity tests with AP-2 enrichment. Significant correlations between microbiota and AP-2 were observed in 18 of 33 analyzed tumor types; TFAP2E-AS1 was most recurrent among AP-2 members, and Halomonas was most recurrent among genera. Further species-level verification and prognostic importance nominated three promising pairs: Paraburkholderia fungorum–TFAP2E in adrenocortical carcinoma (ACC), Actinomyces oris–TFAP2E in diffuse large B-cell lymphoma (DLBC), and Cutibacterium granulosum–TFAP2B in stomach adenocarcinoma (STAD). An attempt to define a consensus expression signature driven by microbiota and AP-2, yet independent of the specific species or family member, revealed genes regulating various biological processes and pathways. ACC and DLBC shared a consensus expression program, whereas STAD diverged; chromatin analysis showed AP-2 motifs near microbe-responsive genes in ACC and DLBC but not STAD, supporting cohort-specific regulation. Collectively, AP-2 family members emerge as plausible mediators of tumor microbiota–host interplay, warranting further mechanistic and translational research. Full article
