Telomerase activity and telomere length in women with breast cancer or without malignancy: A systematic review and meta-analysis. Maturitas 2024; 180:107882. [PMID: 38029511 DOI: 10.1016/j.maturitas.2023.107882] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/02/2023] [Accepted: 10/25/2023] [Indexed: 12/01/2023]
Abstract
AIM We performed a systematic review and meta-analysis to assess whether telomerase activity and telomere length are associated with breast cancer. METHODS PubMed, Web of Science, Embase, LILACS, Scielo, Embase, and CNKI databases were searched to obtain relevant articles published through May 10, 2023, following PRISMA guidelines and a registered PROSPERO protocol (CRD42022335402). We included observational studies reporting telomerase activity or telomere length in patients with breast cancer compared with women with benign lesions or normal tissue (control women). The Newcastle-Ottawa Scale was used to evaluate the quality of studies. Data were expressed as odds ratios (OR) and 95 % confidence intervals (CI). Random effects and inverse variance methods were used to meta-analyze associations. The I2 test was used to assess heterogeneity. RESULTS The meta-analysis of telomerase shows significantly greater activity in patients with breast cancer than in those without malignancies (OR = 23.46, 95 % CI 14.07-39.11, p < 0.00001, I2 = 72 %). There were non-significant differences in relative telomere length (OR = 1.16, 95 % CI = 0.90-1.49, p = 0.26, I2 = 86 %) and leukocyte telomere length (OR = 2.32, 95 % CI = 0.89-6.08, p = 0.09, I2 = 98 %) between women with and without breast cancer. In subgroup analyses by world regions of studies, both telomerase activity and telomere length displayed the same trends as in their respective meta-analyses. In sensitivity analyses, variables showed their respective same trends. CONCLUSION Telomerase activity is higher in patients with breast cancer than in women without malignancies. There were no significant differences in either relative telomere length or leukocyte telomere length in women with and without breast cancer. PROSPERO protocol CRD42022335402.

Abstract
Cancer is considered the most important clinical, social and economic issue regarding cause‑specific disability‑adjusted life years among all human pathologies. Exogenous, endogenous and individual factors, including genetic predisposition, participate in cancer triggering. Telomeres are specific DNA structures positioned at the end of chromosomes and consist of repetitive nucleotide sequences, which, together with shelterin proteins, facilitate the maintenance of chromosome stability, while protecting them from genomic erosion. Even though the connection between telomere status and carcinogenesis has been identified, the absence of a universal or even a cancer‑specific trend renders consent even more complex. It is indicative that both short and long telomere lengths have been associated with a high risk of cancer incidence. When evaluating risk associations between cancer and telomere length, a disparity appears to emerge. Even though shorter telomeres have been adopted as a marker of poorer health status and an older biological age, longer telomeres due to increased cell growth potential are associated with the acquirement of cancer‑initiating somatic mutations. Therefore, the present review aimed to comprehensively present the multifaceted pattern of telomere length and cancer incidence association.

Abstract
Telomeres, and telomere length in particular, have broad significance for genome biology and thus are prime research targets for complex diseases such as cancers. In this context, BRCA1 and BRCA2 gene mutations have been implicated in relationship to telomere length, and breast cancer susceptibility. Yet, the linkages among human genetic variation and telomere length in persons with high hereditary cancer risk are inadequately mapped. We report here original findings in 113 unrelated women at high hereditary risk for breast cancer, who were characterized for the BRCA1 and BRCA2 mutations using next-generation sequencing. Thirty-one BRCA2 and 21 BRCA1 mutations were identified in 47 subjects (41.6%). The women with a mutation in BRCA1 and/or BRCA2 genes had, on average, 12% shorter telomere compared to women with no BRCA1 or BRCA2 mutation (p = 0.0139). Moreover, the association between telomere length and BRCA mutation status held up upon stratified analysis in those with or without a breast cancer diagnosis. We also indentified two rare mutations, c.536_537insT and c.10078A>G, and a novel mutation c.8680C>G in BRCA2 that was studied further by homology modeling of the DNA binding tower domain of BRCA2 and the structure of the protein. These data collectively lend evidence to the idea that BRCA1 and BRCA2 mutations play a role in telomere length in women at high hereditary risk for breast cancer. Further clinical and diagnostics discovery research on BRCA1 and BRCA2 variation, telomere length, and breast cancer mechanistic linkages are called for in larger study samples.

Abstract
Non-communicable diseases (NCDs) are chronic diseases that are by far the leading cause of death in the world. Many occupational hazards, together with social, economic and demographic factors, have been associated to NCDs development. Genetic susceptibility or environmental exposures alone are not usually sufficient to explain the pathogenesis of NCDs, but can be integrated in a more complex scenario that can result in pathological phenotypes. Epigenetics is a crucial component of this scenario, as its changes are related to specific exposures, therefore potentially able to display the effects of environment on the genome, filling the gap between genetic asset and environment in explaining disease development. To date, the most promising biomarkers have been assessed in occupational cohorts as well as in case/control studies and include DNA methylation, histone modifications, microRNA expression, extracellular vesicles, telomere length, and mitochondrial alterations.
