[PMID: 39114035 PMCID: PMC11305230 DOI: 10.1016/j.heliyon.2024.e34079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 07/03/2024] [Accepted: 07/03/2024] [Indexed: 08/10/2024] Open
Abstract
Background A growing corpus of research has revealed that circular RNAs (circRNAs) have become increasingly important for the growth of malignancies in recent years. CircRNAs as ideal candidates for breast cancer (BC) therapeutic targets is still absent. Methods In our study, the dysregulated circRNAs in BC progression were explored, we analysed the BC's circRNA expression profiles using publicly available datasets (GSE101124 and GSE101122). The expression of circZEB1 in BC and cell lines was investigated by qPCR. RNase and actinomycin D were used to examine the features of circZEB1. The function of circZEB1 was subsequently investigated through the utilisation of colony formation, tube formation, transwell assays, and xenograft animal models.RNA immunoprecipitation (RIP), luciferase reporter assays, immunoprecipitation (co-IP) test in conjunction with LC-MS, and ChIP-seq assay to investigate the molecular mechanism underlying the biological activity of circZEB1 in BC. Results Among the circRNAs, we were particularly interested in hsa_circ_0000228, which is spliced from the oncogene ZEB1. In BC cell lines, CircZEB1 expression was upregulated. CircZEB1 knockdown prevented BC cells from migrating and invading, as well as HUVECs from forming tubes and developing. By sponging miR-337-3p, functional testing revealed that circZEB1 promoted O-GlcNAcylation, increased YBX1, and OGT expression. Moreover, circZEB1 overexpression is reversible, in contrast to YBX1 knockdown, which mostly results in the downregulation of multiple oncogenes. Conclusion Our study indicate that circZEB1 had oncogenic function in BC by focusing on circZEB1/miR-337-3p/OGT and YBX1. It might be inferred that circZEB1 could be a promising new target for BC treatment.

Association between epidemiological and clinico-pathological features of breast cancer with prognosis, family history, Ki-67 proliferation index and survival in Tunisian breast cancer patients. PLoS One 2022; 17:e0269732. [PMID: 36094928 PMCID: PMC9467370 DOI: 10.1371/journal.pone.0269732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Accepted: 05/26/2022] [Indexed: 11/19/2022] Open
Abstract
Breast cancer has different epidemio-clinical characteristics in Middle East and North-African populations compared to those reported in the Western countries. The aim of this study is to analyze the epidemiological and clinico-pathological features of breast cancer in Tunisia and to determine prognostic factors with special interest to family history, Ki-67 proliferation index and comorbidity. We retrospectively reviewed epidemiological and clinico-pathological data from patients’ medical records, treated in the Medical Oncology Department at Abderrahmane Mami Hospital, in the period 2011–2015. Data has been collected on 602 breast cancer patients and analyzed using SPSS software V.23.0. Our study showed high fractions of young breast cancer patients and cases with dense breasts. The most prevalent comorbidities observed in the studied cohort were cardiovascular diseases and diabetes. Familial breast cancer was found in 23.3% of cases and was associated with younger age at diagnosis (p<0.001) and advanced stage (p = 0.015). Ki-67 index >20% was significantly associated with early age at diagnosis, lymph node involvement (p = 0.002), advanced tumor grade (p<0.001) and high risk of relapse (p = 0.007). Ki-67 cut-off 30% predicted survival in luminal cases. Survival was worse in patients with triple negative breast cancer compared to non-triple negative breast cancer, inflammatory breast cancer compared to non-inflammatory breast cancer, moderately to poorly differentiated tumors compared to well-differentiated tumors and with positive lymph nodes compared to pN0 (p<0.05). Our study showed new insights into epidemiological and clinico-pathological characteristics of breast cancer that are not well explored in Tunisian population. Considering our findings along with the implementation of electronic health record system may improve patient health care quality and disease management.

Li L, Lv D, Zhai J, Zhang D, Guan X, Ma F. Breast Cancer in Chinese Females Aged 25 Years and Younger. JOURNAL OF ONCOLOGY 2021; 2021:4891936. [PMID: 34887923 PMCID: PMC8651374 DOI: 10.1155/2021/4891936] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Accepted: 11/16/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Breast cancer has both aggressive clinicopathological characteristics and a poor prognosis in young females. However, limited information is available for breast cancer in Chinese females aged ≤25 years. Therefore, we aimed to explore prognostic factors for invasive disease-free (iDFS) and overall survival (OS) among breast cancer patients aged ≤25 years. METHODS We retrospectively analyzed data from 174 Chinese females aged ≤25 years with invasive breast cancer treated in the Cancer Hospital of the Chinese Academy of Medical Sciences from January 1, 1999, to December 31, 2018. Univariate and multivariate Cox regression analyses were performed to identify independent prognostic factors. RESULTS The median follow-up time was 75 months (ranging from 1 to 236 months). Breast cancer patients aged ≤25 years exhibited aggressive clinicopathological characteristics, including advanced tumor stage (21.8%), lymph node metastasis (47.1%), lymphovascular invasion (24.1%), estrogen receptor negativity (44.3%), progesterone receptor (PR) negativity (42.5%), and triple-negative breast cancer (25.3%). Among them, 50 cases had locoregional recurrence and metastasis, 20 had bilateral invasiveness, and 33 had breast cancer-specific deaths. Cox multivariate analysis identified that diagnosis delay, PR status, and radiotherapy were significant prognostic factors for both iDFS and OS (P < 0.05). The risk of recurrence and metastasis was five times higher in N3 than in N0 (HR: 6.778, 95% CI: 2.268-17.141, P < 0.001). Patients with lymphovascular invasion had a threefold increase in the risk of breast cancer-specific death (HR: 4.217, 95% CI: 1.956-9.090, P < 0.001). No differences were observed between mastectomy and breast-conserving surgery (BCS) plus radiotherapy for iDFS or OS (iDFS: χ 2 = 0.678, P=0.410; OS: χ 2 = 0.165, P=0.685). CONCLUSIONS Breast cancer in females ≤25 years old was associated with aggressive clinical features and a worse prognosis. Young females with breast lumps should receive timely diagnosis and treatment. Young breast cancer patients with lymphovascular invasion, PR-negative status, and lymph node metastasis have an increased risk of experiencing recurrence and metastasis and should hence be closely monitored. Age at diagnosis should not be the sole deciding factor for surgical treatment methods.
