Eribulin induces micronuclei and enhances the nuclear localization of cGAS in triple-negative breast cancer cells.

Eribulin (ERI), clinically utilized for locally advanced or metastatic breast tumors, has shown potential links to the immune system. Notably, the cGAS-STING pathway, a key component of innate immunity, has gained prominence. Yet, limited reports explore ERI's effects on the cGAS-STING pathway.

New genetic and epigenetic insights into the chemokine system: the latest discoveries aiding progression toward precision medicine.

Over the past thirty years, the importance of chemokines and their seven-transmembrane G protein-coupled receptors (GPCRs) has been increasingly recognized. Chemokine interactions with receptors trigger signaling pathway activity to form a network fundamental to diverse immune processes, including host homeostasis and responses to disease. Genetic and nongenetic regulation of both the expression and structure of chemokines and receptors conveys chemokine functional heterogeneity.

Less necessity of adjuvant S-1 treatment in non-monarchE-eligible patients.

Background: In monarchE and Postoperative Therapy with Endocrine and TS-1 (POTENT) trials, abemaciclib and S-1 have, respectively, shown to be effective as adjuvant therapies for luminal breast cancer (BC), although whether patients who meet the criteria are at high risk of recurrence compared to non-eligible patients is still unknown. Here, we investigated recurrence risk according to the criteria of each trial in Japanese patients.

Methods: We reviewed the records of 992 patients who received surgery at Chiba University Hospital for stage I-III BC from January 2017 to May 2022 and selected 553 analytic cohort patients and retrospectively analyzed the relapse-free survival of the patients as the primary endpoint.
