Special Issue Information

Dear Colleagues,

This Special Issue, “Targeting Apoptosis Pathways in Cancer”, will cover a selection of recent research topics and current review articles related to the intracellular signaling of resistance to apoptosis in cancer. Up-to-date review articles, commentaries, and experimental papers are all welcome.

Programmed cell death or apoptosis is a natural mechanism by which organisms control the number of cells. It plays an important role in embryonic development and in maintaining cell homeostasis. Deregulation of apoptosis machinery induces resistance to apoptosis. This resistance is characterized by inhibition of cell death triggering or delay in cell death unfolding in response to an apoptotic stimulus. Apoptosis resistance plays an important role in tumor development. Uncontrolled cell proliferation combined with resistance to apoptosis is both necessary and sufficient for tumor progression to a malignant phenotype. Although there are several mechanisms by which cells escape apoptosis, the majority of these lead to an inability for the cell to trigger the intrinsic pathway of apoptosis (called the mitochondrial pathway). Despite numerous studies of the survival pathways in the apoptosis resistance mechanism, the signaling pathways involved have not yet been fully elucidated and there are disparities regarding their role in this mechanism.

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.

Euphorbiasteroid (EPBS) has gained attention for its activity against human lung cancer and sarcoma; however, its impact on hepatocellular carcinoma has not yet been elucidated. Here, we investigated the cytotoxic effect of EPBS on human hepatocellular carcinoma (HCC) cells. We found that EPBS induced both apoptosis and autophagy in HCC cells. Additionally, we observed that EPBS treatment suppressed the constitutive as well as the inducible activation of a signal transducer and activator of transcription 3 (STAT3) protein expression. Moreover, EPBS promoted the expression of SHP-1 protein and the production of reactive oxidative stress (ROS). Furthermore, the knockdown of SHP-1 by siRNA transfection reversed the effects of EPBS, which have inductive effects related to apoptosis and autophagy. Therefore, EPBS can potentially function as an anti-cancer agent by inducing apoptosis and autophagy when targeting the SHP-1/STAT3 pathway. Full article
