Special Issue Information

Dear Colleagues,

The incidence rate for various cancer types, including gastric cancer, colorectal cancer, lung cancer, ovary cancer, and breast cancer is the leading cause of death worldwide. The tumor therapeutic strategy has reduced mortality and recurrence; however, acquired resistance is still unclear. Multifaced mechanisms such as drug resistance, radioresitance, hypoxia, and growth factor deprivation are associated with a number of genes and signaling pathways that process the proliferation and cell death of cells. Reasons for resistance include autophagy, ER stress, DNA damage, endocytosis, oxidants, epithelial mesenchyme, epigenetic modification, pathway activation, cancer-related fibroblasts, extracellular matrix (ECM), exosomes, inflammatory immune cells, and so on. To overcome diverse chemoresistance, the relationship between the cell signaling pathway and resistant cancer models is important in studying the mechanism for tumor survival and cell death. Novel or famous antitumor reagents against various resistant cancer models represent a new, advanced strategy to overcome resistance on cancer therapy, but the underlying mechanisms are not fully clarified. This Special Issue of IJMS, “New Advances to Overcome Resistance in Tumor Therapy” will focus on new advanced therapeutic strategies to overcome chemoresistance in various resistant cancer models. Moreover, we will suggest progress in the understanding of various resistance cancer types and focus on therapeutic approaches to develop new treatments to overcome chemoresistance.

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.

Saikosaponin A is a triterpene saponin and a potentially bioactive compound derived from Bupleurum falcatum L. However, the molecular mechanisms and effects of saikosaponin A in gastric cancer remain unknown. In the present study, I evaluated the effects of saikosaponin A on cell death and endoplasmic reticulum stress via calcium and reactive oxygen species release. Targeting reactive oxygen species with diphenyleneiodonium and N-acetylcysteine inhibited cell death and protein kinase RNA-like ER kinase signaling pathway by down-regulating Nox4 and inducing glucose-regulated protein 78 exosomes. Furthermore, saikosaponin A caused a synergistic inhibitory effect of the epithelial mesenchymal transition phenomenon, indicating the reversible phenotype modulation by epithelial cells under radiation exposure in radiation-resistant gastric cancer cells. These results suggest that saikosaponin A-mediated calcium and reactive oxygen species-induced endoplasmic reticulum stress overcome radio-resistance and induce cell death under radiation in gastric cancer cells. Therefore, saikosaponin A in combination with radiation may be a potential strategy for gastric cancer therapy. Full article
