Special Issue Information
Dear Colleagues,
Gastric cancer remains one of the most lethal malignancies worldwide, continuing to pose a major challenge in clinical oncology. Despite advances in diagnosis and therapy, the prognosis for patients with advanced or recurrent gastric cancer remains poor. Systemic multidrug chemotherapy is widely applied as a standard treatment; however, its efficacy is often hampered by tumor heterogeneity and the frequent emergence of chemoresistance.
Accumulating evidence highlights the pivotal role of gastric cancer stem cells (CSCs) in mediating chemoresistance, tumor relapse, and metastasis. CSCs possess unique capabilities for self-renewal, differentiation, and tumor initiation, enabling them to survive conventional treatments and repopulate tumors. Among the key regulatory pathways, nuclear factor erythroid 2-related factor 2 (Nrf2) has emerged as a crucial transcription factor maintaining cellular redox balance by regulating antioxidant enzyme expression. Enhanced Nrf2 activity within CSCs contributes to their resistance to oxidative stress and therapy-induced cytotoxicity. Nrf2-mediated extracellular vesicles (EVs) also play a pivotal role in facilitating communication between CSCs and tumor microenvironment cells.
The interplay between CSCs and antioxidant transcriptional networks, such as Nrf2 signaling, represents a novel conceptual framework for understanding gastric cancer progression and therapeutic resistance. Exploring this crosstalk could unveil innovative strategies for targeting redox homeostasis and stemness in gastric tumors. Furthermore, increasing evidence suggests that nutritional or natural compounds capable of modulating antioxidant pathways and CSC activity may offer promising preventive or therapeutic benefits in gastrointestinal cancers.
In line with these emerging insights, this Special Issue welcomes original research articles, reviews, and communications focusing on novel treatment strategies, molecular mechanisms of chemoresistance, and the pathogenesis of gastrointestinal cancers. Studies exploring the biological regulation of CSCs, redox signaling, EVs-gastric cancer cell communication and the therapeutic potential of natural compounds are particularly encouraged.

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. Current Issues in Molecular Biology 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 2200 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.
