Abstract
OBJECTIVE Breast cancer is a malignant tumor in the epithelial tissue of the breast gland. This study aimed to unveil the expression and clinical diagnostic value of lncRNA cervical cancer high-expressed 1 (CCHE1) in breast cancer. METHODS CCHE1 expression in breast cancer tissues was evaluated by RT-qPCR. The relationship between the CCHE1 expression and clinicopathological features of breast cancer was analyzed with the chi-square test, and the survival of breast cancer patients was evaluated with the Kaplan-Meier method. The diagnostic value of CCHE1 expression for breast cancer was evaluated by using the receiver operating characteristics (ROC) curve. Breast cancer cell lines (SKBR3, T47D, BT474, and MCF-7) were cultured for detecting CCHE1 expression in the cells. MCF-7 cells were selected for the subsequent experiments, and the small interfering RNA of CCHE1 (si-CCHE1) and CCHE1 overexpression vector (pcDNA-CCHE1) were transfected into MCF-7 cells. The proliferation, migration, and invasive ability were assessed by CCK-8 and Transwell assays. The influence of CCHE1 on the growth of tumors was validated by nude mice xenograft assay. RESULTS CCHE1 was up-regulated in breast cancer tissues and breast cancer cells. The high expression level of CCHE1 in cancer tissues of breast cancer patients was correlated with larger tumor size, advanced TNM stage, Ki-67 status, and lymph node metastasis. The area under the ROC curve for CCHE1 in the diagnosis of breast cancer was 0.983 (95% CI: 0.966-1.000), with a sensitivity of 95.00% and a specificity of 91.70%. The 5-year survival rate was higher in patients with low CCHE1 expression than those with high CCHE1 expression. Furthermore, restrained CCHE1 impeded proliferation, invasion, and migration of MCF-7 cells, as well as tumor growth in mice. CONCLUSION Our study highlights that elevated expression of CCHE1 in breast cancer tissues, which is closely related to clinicopathologic features, has some clinical value in the diagnosis of the disease.

Abstract
Background The objective of this study is to search for mutations in the BRCA1 (c.5177_5180delGAAA and c.4986+6T>C) and BRCA2 genes (c.6445_6446delAT) in a population of women diagnosed with breast cancer. Methods This is a case-control study that involved 140 participants, including 70 patients with histologically diagnosed breast cancer and 70 healthy women without breast cancer. Mutations in the BRCA1 (rs80357867, rs80358086) and BRCA2 (rs80359592) genes were tested by real-time PCR. The 95% confidence interval Odds Ratio (OR) was used to estimate the associations between specific genotypes and breast cancer. Results The study revealed that no mutations were detected for rs80359592. Similarly, no reference allele (TTTC/TTTC) of rs80357867 was found in this study. However, the homozygous double mutant (-/) genotype of this rs80357867 was observed in 11.43% and 1.43% of patients and controls respectively, while 88.57% of patients and 98.57% of controls had a heterozygous deletion (TTTC/-). Concerning rs80358086, 8.57% of the patients had a heterozygous mutation (A/G) with no significantly risk association with occurrence of breast cancer (OR = 6.46; 95% CI: 0.75-55.21; p = 0.11). In addition, this heterozygous mutation was significantly associated with a family history of breast cancer (OR=128; 95% CI: 9.46-1730.93) and breast cancer risk in nonmultiparous women (OR=6; 95% CI: 1-35.90; p= 0.05) but no association with overweight/obesity (OR=1.66; 95% CI: 0.18-15.35; p=1). Conclusion This study shows high frequencies of heterozygous mutation of rs80357867 and rs80358086 from patients. In Burkina Faso, these results could help with early diagnosis of breast cancer in patients.

Haplotypes of single cancer driver genes and their local ancestry in a highly admixed long-lived population of Northeast Brazil. Genet Mol Biol 2022; 45:e20210172. [PMID: 35112701 PMCID: PMC8811751 DOI: 10.1590/1678-4685-gmb-2021-0172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Accepted: 11/17/2021] [Indexed: 12/02/2022] Open
Abstract
Admixed populations have not been examined in detail in cancer genetic studies.
Here, we inferred the local ancestry of cancer-associated single nucleotide
polymorphisms (SNPs) and haplotypes of a highly admixed Brazilian population.
SNP array was used to genotype 73 unrelated individuals aged 80-102 years. Local
ancestry inference was performed by merging genotyped regions with phase three
data from the 1000 Genomes Project Consortium using RFmix. The average ancestry
tract length was 9.12-81.71 megabases. Strong linkage disequilibrium was
detected in 48 haplotypes containing 35 SNPs in 10 cancer driver genes. All
together, 19 risk and eight protective alleles were identified in 23 out of 48
haplotypes. Homozygous individuals were mainly of European ancestry, whereas
heterozygotes had at least one Native American and one African ancestry tract.
Native-American ancestry for homozygous individuals with risk alleles for
HNF1B, CDH1, and BRCA1 was inferred for
the first time. Results indicated that analysis of SNP polymorphism in the
present admixed population has a high potential to identify new
ancestry-associated alleles and haplotypes that modify cancer susceptibility
differentially in distinct human populations. Future case-control studies with
populations with a complex history of admixture could help elucidate
ancestry-associated biological differences in cancer incidence and therapeutic
outcomes.

Breast cancer in West Africa: molecular analysis of BRCA genes in early-onset breast cancer patients in Burkina Faso. Hum Genomics 2021; 15:65.

Abstract
BACKGROUND Breast cancer (BC) is the most commonly diagnosed cancer and the second leading cause of cancer-related deaths among women in Africa after cervical cancer. Even if the epidemiological data are now aligned with those relating to industrialized countries, the knowledge concerning breast cancer in Africa, particularly in Western Africa, still lack clinical data, medical treatments, and the evaluation of genetic and non-genetic factors implicated in the etiology of the disease. The early onset and the aggressiveness of diagnosed breast cancers in patients of African ancestry strongly suggest that the genetic risk factor may be a key component, but so far, very few studies on the impact of germ line mutations in breast cancer in Africa have been conducted, with negative consequences on prevention, awareness and patient management. Through Next Generation sequencing (NGS), we analyzed all of the coding regions and the exon-intron junctions of BRCA1 and BRCA2 genes-the two most important genes in hereditary breast cancer-in fifty-one women from Burkina Faso with early onset of breast cancer with or without a family history. RESULTS We identified six different pathogenic mutations (three in BRCA1, three in BRCA2), two of which were recurrent in eight unrelated women. Furthermore, we identified, in four other patients, two variants of uncertain clinical significance (VUS) and two variants never previously described in literature, although one of them is present in the dbSNP database. CONCLUSIONS This is the first study in which the entire coding sequence of BRCA genes has been analyzed through Next Generation Sequencing in Burkinabe young women with breast cancer. Our data support the importance of genetic risk factors in the etiology of breast cancer in this population and suggest the necessity to improve the genetic cancer risk assessment. Furthermore, the identification of the most frequent mutations of BRCA1 and BRCA2 in the population of Burkina Faso will allow the development of an inexpensive genetic test for the identification of subjects at high genetic cancer risk, which could be used to design personalized therapeutic protocols.

Identification of Variants (rs11571707, rs144848, and rs11571769) in the BRCA2 Gene Associated with Hereditary Breast Cancer in Indigenous Populations of the Brazilian Amazon. Genes (Basel) 2021; 12:genes12020142. [PMID: 33499154 PMCID: PMC7911168 DOI: 10.3390/genes12020142] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 01/14/2021] [Accepted: 01/20/2021] [Indexed: 12/09/2022] Open
Abstract
Estimates show that 5–10% of breast cancer cases are hereditary, caused by genetic variants in autosomal dominant genes; of these, 16% are due to germline mutations in the BRCA1 and BRCA2 genes. The comprehension of the mutation profile of these genes in the Brazilian population, particularly in Amazonian Amerindian groups, is scarce. We investigated fifteen polymorphisms in the BRCA1 and BRCA2 genes in Amazonian Amerindians and compared the results with the findings of global populations publicly available in the 1000 Genomes Project database. Our study shows that three variants (rs11571769, rs144848, and rs11571707) of the BRCA2 gene, commonly associated with hereditary breast cancer, had a significantly higher allele frequency in the Amazonian Amerindian individuals in comparison with the African, American, European, and Asian groups analyzed. These data outline the singular genetic profiles of the indigenous population from the Brazilian Amazon region. The knowledge about BRCA1 and BRCA2 variants is critical to establish public policies for hereditary breast cancer screening in Amerindian groups and populations admixed with them, such as the Brazilian population.
