Eribulin induces micronuclei and enhances the nuclear localization of cGAS in triple-negative breast cancer cells. Sci Rep 2024; 14:14146. [PMID: 38898119 PMCID: PMC11187130 DOI: 10.1038/s41598-024-64651-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Accepted: 06/11/2024] [Indexed: 06/21/2024] Open
Abstract
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. Additionally, the nuclear presence of cGAS remains poorly understood. This study uniquely delves into ERI's impact on both the cytosolic cGAS-STING pathway and nuclear cGAS. ERI enhances nuclear localization of cGAS, resulting in hyper-activation of the cGAS-STING pathway in triple-negative breast cancer cells. Reduction of cGAS heightened both cell proliferation and ERI sensitivity. In clinical data using ERI in a neo-adjuvant setting, patients with low cGAS cases exhibited reduced likelihood of achieving pathological complete response after ERI treatment. These findings illuminate the potential of cGAS and IFNβ as predictive biomarkers for ERI sensitivity, providing valuable insights for personalized breast cancer treatment strategies.

Abstract
BACKGROUND Measurements on DNA content and steroid receptor status in breast cancer are of great clinical interest. Objective determination of estrogen and progesterone receptor expression should help to define the lowest levels of positivity still responding to adjuvant antihormonal therapy. For this purpose, a simple protocol for laser scanning cytometry is presented. METHODS Analysis of 54 routine breast cancer samples was performed by laser scanning cytometry (LSC). To obtain single cell preparations from fresh tumor tissue, slides were prepared using the Cervisoft cytological device. Exact determination of tumor cell DNA content was done by referring to the CD45-positive tissue leukocyte fraction as the internal diploid reference cell population. Steroid receptor-expressing cells were detected by indirect immunolabeling. RESULTS Indirect immunofluorescence allowed the best quantification of both the estrogen and progesterone receptor-expressing cell fractions by LSC. The number of receptor-expressing cells could be given in percentage. For comparison, the 10% cutoff value was used to determine receptor positivity. CONCLUSION LSC enabled a simple, reliable, and inexpensive determination of DNA index and steroid receptor expression in breast cancer specimens by objective criteria.

Abstract
Tests for estrogen (ER) and progesterone (PR) receptors, c-erbB-2, p53 and Bcl-2 were made on paraffin sections of thirty-three cases of invasive micropapillary carcinoma (MPCa) of the breast. The relations between these proteins and general parameters and the patients' evolution, were analyzed and their statistical significance determined by Fisher's exact test. Follow up was available on twenty one patients of whom thirteen were alive after a mean of sixty months. Tumor size, metastatic nodes, c-erbB-2 and Bcl-2 all showed higher values in the dead patient group, but only nuclear grade and extensive lymphatic vessel invasion (LVI) were statistically significant prognostic factors. Hormone receptors and oncogenes were positive in quite similar figures to those of common breast cancers (NOSCa) and offered supplementary information about differentiation and cell atypia of individual cancers. Accordingly, ER (72.7%), PR (45.4%) and Bcl-2 (69.6%) were directly interrelated and inversely related with nuclear grade, mitotic grade, c-erbB-2 (36.3%) and p53 (12.1%). In conclusion, MPCa is a lymphotropic cancer phenotype whose prognosis can be influenced by known prognostic factors, including molecular. The lack of discriminative power between MPCa and NOSCa of ER, PR, c-erbB-2, p53, and Bcl-2 reinforces the importance of recognizing this particular type of cancer.

Abstract
The nuclear specific surface density (Sv/Vv), mean nuclear area (A) and numerical density (Nv) of tumor cell nuclei from 30 primary invasive female breast carcinomas with known concentrations of estrogen and progesterone receptors (ER and PR), were morphometrically analyzed at the ultrastructural level. It was found that carcinomas with concordant positive ER and PR status contained significantly higher number of smaller nuclei per volume unit of epithelium (mean Nv = 1.5 x 10(6) mm-3, mean A = 27 microns 2), than carcinomas of negative concordant receptor status (mean Nv = 0.8 x 10(6) mm-3, mean = 37 microns 2). Tumor cell nuclei of the former frequently displayed an elliptic shape (mean Sv/Vv = 1.16 microns-1), and had deeply invaginated surfaces, whereas nuclei of the latter were more frequently ball-shaped and exhibited a smooth-surface (mean Sv/Vv = 0.88 microns-1). The numerical density Nv (NUC/EPI) of tumor cell nuclei turned out to be a most reliable morphological marker of the concordant ER and PR status (overall efficiency = 84%, p < 0.01). The nuclear surface and volume ratio and mean nuclear area also appear to be reliable markers for terminal stages of the biochemical differentiation of breast carcinoma (overall efficiency = 79%, p < 0.05).
