Abstract
Breast cancer, the most prevalent malignant tumor among women globally, is significantly influenced by the Wnt/β-catenin signaling pathway, which plays a crucial role in its initiation and progression. While conventional chemotherapy, the standard clinical treatment, suffers from significant drawbacks like severe side effects, high toxicity, and limited prognostic efficacy, Traditional Chinese Medicine (TCM) provides a promising alternative. TCM employs a multi-targeted therapeutic approach, which results in fewer side effects and offers a high potential for effective treatment. This paper presents a detailed analysis of the therapeutic impacts of TCM on various subtypes of breast cancer, focusing on its interaction with the Wnt/β-catenin signaling pathway. Additionally, it explores the effectiveness of both monomeric and compound forms of TCM in the management of breast cancer. We also discuss the potential of establishing biomarkers for breast cancer treatment based on key proteins within the Wnt/β-catenin signaling pathway. Our aim is to offer new insights into the prevention and treatment of breast cancer and to contribute to the standardization of TCM.

Cabarcas-Petroski S, Olshefsky G, Schramm L. MAF1 is a predictive biomarker in HER2 positive breast cancer. PLoS One 2023; 18:e0291549. [PMID: 37801436 PMCID: PMC10558074 DOI: 10.1371/journal.pone.0291549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 09/01/2023] [Indexed: 10/08/2023] Open
Abstract
RNA polymerase III transcription is pivotal in regulating cellular growth and frequently deregulated in various cancers. MAF1 negatively regulates RNA polymerase III transcription. Currently, it is unclear if MAF1 is universally deregulated in human cancers. Recently, MAF1 expression has been demonstrated to be altered in colorectal and liver carcinomas and Luminal B breast cancers. In this study, we analyzed clinical breast cancer datasets to determine if MAF1 alterations correlate with clinical outcomes in HER2-positive breast cancer. Using various bioinformatics tools, we screened breast cancer datasets for alterations in MAF1 expression. We report that MAF1 is amplified in 39% of all breast cancer sub-types, and the observed amplification co-occurs with MYC. MAF1 amplification correlated with increased methylation of the MAF1 promoter and MAF1 protein expression is significantly decreased in luminal, HER2-positive, and TNBC breast cancer subtypes. MAF1 protein expression is also significantly reduced in stage 2 and 3 breast cancer compared to normal and significantly decreased in all breast cancer patients, regardless of race and age. In SKBR3 and BT474 breast cancer cell lines treated with anti-HER2 therapies, MAF1 mRNA expression is significantly increased. In HER2-positive breast cancer patients, MAF1 expression significantly increases and correlates with five years of relapse-free survival in response to trastuzumab treatment, suggesting MAF1 is a predictive biomarker in breast cancer. These data suggest a role for MAF1 alterations in HER2-positive breast cancer. More extensive studies are warranted to determine if MAF1 serves as a predictive and prognostic biomarker in breast cancer.

Estrone, the major postmenopausal estrogen, binds ERa to induce SNAI2, epithelial-to-mesenchymal transition, and ER+ breast cancer metastasis. Cell Rep 2022; 41:111672. [PMID: 36384125 PMCID: PMC9798480 DOI: 10.1016/j.celrep.2022.111672] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 09/22/2022] [Accepted: 10/25/2022] [Indexed: 11/18/2022] Open
Abstract
Recent work showed that the dominant post-menopausal estrogen, estrone, cooperates with nuclear factor κB (NF-κB) to stimulate inflammation, while pre-menopausal 17β-estradiol opposes NF-κB. Here, we show that post-menopausal estrone, but not 17β-estradiol, activates epithelial-to-mesenchymal transition (EMT) genes to stimulate breast cancer metastasis. HSD17B14, which converts 17β-estradiol to estrone, is higher in cancer than normal breast tissue and in metastatic than primary cancers and associates with earlier metastasis. Treatment with estrone, but not 17β-estradiol, and HSD17B14 overexpression both stimulate an EMT, matrigel invasion, and lung, bone, and liver metastasis in estrogen-receptor-positive (ER+) breast cancer models, while HSD17B14 knockdown reverses the EMT. Estrone:ERα recruits CBP/p300 to the SNAI2 promoter to induce SNAI2 and stimulate an EMT, while 17β-estradiol:ERα recruits co-repressors HDAC1 and NCOR1 to this site. Present work reveals novel differences in gene regulation by these estrogens and the importance of estrone to ER+ breast cancer progression. Upon loss of 17β-estradiol at menopause, estrone-liganded ERα would promote ER+ breast cancer invasion and metastasis.

Abstract
Introduction Breast cancer is a leading cause of death among women. This study aimed to evaluate the association between age and hormonal receptor status (HRS) in women with breast cancer presented at a public hospital in Karachi, Pakistan. Methods A cross-sectional study was conducted at the Department of Medical Oncology, Jinnah Postgraduate Medical Center (JPMC), Karachi, Pakistan, from January 2021 to August 2021. All women of age more than 18 years with a confirmed diagnosis of breast cancer were included in the study using non-random consecutive sampling techniques. Women who underwent artificial menopause or hysterectomy, women who had chemotherapy-induced menopause, and pregnant women were excluded from the study. Data were collected from all patients regarding socio-demographics and tumor characteristics. Immunohistochemistry (IHC) was performed to evaluate the status of hormonal receptors. Results The mean age at the time of presentation of females with breast cancer was 46.57±11.45 years. Among 317 females, 180 females had positive estrogen receptor (ER) expression (56.8%), 173 had positive progesterone receptor (PR) expression (54.6%), and 121 had positive human epidermal growth factor receptor 2 (HER2/neu) expression (38.2%). The highest proportions of positive ER (36.7%), PR (38.2%), and HER/2 neu (37.2%) expression were observed in the age group 41-50 years, respectively. There was a statistically significant association between age and ER expression (p=0.017) and age and PR expression (p=0.003) while no association was found between age and HER/2 neu expression (p=0.335). Conclusion The present study indicated that the majority of the patients were diagnosed with breast cancer in their 40s. Most of the women in the younger age groups were estrogen receptor (ER), progesterone receptor (PR), and HER2/neu negative while the older aged women were more frequently ER, PR, and HER2/neu positive albeit, the association between age or HER2/neu was not significant. In short, we can expect that the older aged patients may have better survival rates and patient prognosis. However, this is just a conjecture and further large-scale, multicenter, and long-term studies are required to understand the true relationship between age and patient survival rates. We hope that the current study will serve as a catalyst for future breast-cancer related studies.

Abstract
BACKGROUND Clinical and genomic data from patients with early-stage breast cancer suggest more aggressive disease in premenopausal women. However, the association between age, disease course, and molecular profile from liquid biopsy in metastatic breast cancer (MBC) is not well characterized. METHODS Patients were classified as premenopausal (< 45 years), perimenopausal (45-55 years), or postmenopausal (> 55 years). Cohort 1 consisted of patients with MBC who consented for prospective serial evaluation of circulating tumor cells (CTCs) using CellSearch™. Cohort 2 included patients who, as part of routine care, had circulating tumor DNA (ctDNA) sequenced by the Guardant360™ assay. Clinicopathologic data were collected from retrospective review to compare disease features between premenopausal and postmenopausal women. RESULTS Premenopausal women represented 26% of 138 patients in Cohort 1 and 21% of 253 patients in Cohort 2. In Cohort 1, younger patients had a shorter time to metastases and a higher prevalence of lung and brain metastases. Overall, there were similar rates of ≥ 5 CTCs/7.5 mL, HER2 + CTC expression, and CTC clusters between pre- and postmenopausal women. However, for those with triple negative breast cancer, premenopausal women had a higher proportion of ≥ 5 CTCs/7.5 mL. In Cohort 2, premenopausal women had a higher incidence of FGFR1 (OR 2.75, p = 0.022) and CCND2 (OR 6.91, p = 0.024) alterations. There was no difference in the ctDNA mutant allele frequency or the number of detected alterations between these age groups. CONCLUSIONS Our data reveal that premenopausal women diagnosed with MBC have unique clinical, pathologic, and molecular features when compared to their postmenopausal counterparts. Our results highlight FGFR1 inhibitors as potential therapeutics of particular interest among premenopausal women.

Abstract
Hormone receptor positivity and early stage diagnosis are generally considered signs of good prognosis in breast cancer. However, breast cancer all too frequently can become resistant to hormone-based therapies, and women can experience recurrence of their breast cancer decades after the diagnosis of early stage disease. To address the therapeutic needs for advanced and metastatic hormone receptor-positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-) breast cancer, a number of new drugs have been tested and approved for this indication, including the class of drugs that works as cyclin-dependent kinase (CDK) 4/6 inhibitors. These drugs, often combined with other hormone-based therapy, have demonstrated considerable success in clinical trials and are now being used widely in oncology practices. Because all of the currently approved CDK4/6 inhibitor agents (palbociclib, ribociclib, and abemaciclib) are given orally, issues of patient comprehension of and adherence to prescribed regimens should be at the forefront of practitioners' concerns about these drugs. In addition, ways to support and facilitate decision-making by patients related to this class of agents and other therapies recently approved for the same indication require focused attention by health-care providers. Oncology has continued to move toward a more patient-specific, precision medicine approach. Likewise, advanced practitioners have the opportunity to identify patient characteristics, preferences, and needs that are unique to individual patients to enhance precision treatment.

Abstract
Background The expression of estrogen and progesterone receptors (ER and PR) and human epidermal growth factor receptor-2 (HER2) has been reported to have an invaluable prognostic role. The aim of this study was to determine the expression of ER, PR and HER2 in women with breast cancer (BC) in Kampala, Uganda. Methods Expression of ER, PR and HER2 was determined immunohistochemically. Logistic regression was performed to determine the effect of the independent factors in predicting the risk of not expressing the breast markers. A two-tailed p<0.05 was regarded to be statistically significant. Results ER, PR and HER2 were expressed in 53.4%, 46.6% and 18.5%, respectively. ER and PR co-expression was present in 42.7% and 37.9% patients had triple negative breast cancer (TNBC). Age was an independent predictor of expression of ER (AOR = 0.18, 95% CI = 0.062–0.541, p = 0.002) and PR (AOR = 0.35, 95% CI = 0.129–0.968, p = 0.043). Conclusion The majority of patients in this study had less than 50 years with high tumour grade. Interestingly, most of them had high expression of HER2 with TNBC which are molecular subtypes of BC with poor prognosis. Age was an independent predictor of expression of both ER and PR.

Abstract
Breast cancer is the most common malignancy in young women worldwide, accounting for an estimated 30% of new cancer diagnoses and 25% of cancer deaths. Approximately two thirds of young women with breast cancer have hormone receptor-positive (HR+)/human epidermal growth receptor 2-negative (HER2-) tumors. Numerous studies, primarily in early-stage breast cancer, have demonstrated that young age is an independent risk factor for more aggressive disease and worse outcomes. Although more limited data are available regarding outcomes in young patients with advanced disease, these age-related disparities suggest that breast cancer in premenopausal women has distinct clinicopathologic and molecular features that can impact treatment outcomes. Until recently, limited data were available on the intrinsic molecular subtypes and genetics of young patients with HR+/HER2- metastatic breast cancer (mBC). In this review, we explore insights into the clinical and pathologic features of HR+/HER2- mBC in younger women derived from recent clinical trials of the cyclin-dependent kinase 4/6 inhibitors palbociclib (PALOMA-3), ribociclib (MONALEESA-7), and abemaciclib (MONARCH 2) and the implications of these findings for clinical practice, guideline development, and future research. IMPLICATIONS FOR PRACTICE: This review provides clinicians with an overview of emerging data on the unique clinicopathologic and molecular features of hormone receptor-positive/human epidermal growth receptor 2-negative metastatic breast cancer (mBC) in premenopausal women, summarizes findings from the most recent clinical trials of endocrine-based treatment in this patient population, and explores the implications of these findings for clinical practice, guideline development, and future research. Improved understanding of the key factors influencing disease course and treatment response in premenopausal patients with mBC may lead to more timely incorporation of evidence-based treatment approaches, thereby improving patient care and outcomes.

Abstract
Background The presence of circulating tumor cells (CTCs) in patients with breast cancer correlates to a bad prognosis. Yet, CTCs are detectable in only a minority of patients with progressive breast cancer, and factors that influence the abundance of CTCs remain elusive. Methods We conducted CTC isolation and enumeration in a selected group of 73 consecutive patients characterized by progressive invasive breast cancer, high tumor load and treatment discontinuation at the time of CTC isolation. CTCs were quantified with the Parsortix microfluidic device. Clinicopathological variables, blood counts at the time of CTC isolation and detailed treatment history prior to blood sampling were evaluated for each patient. Results Among 73 patients, we detected at least one CTC per 7.5 ml of blood in 34 (46%). Of these, 22 (65%) had single CTCs only, whereas 12 (35%) featured both single CTCs and CTC clusters. Treatment with the monoclonal antibody denosumab correlated with the absence of CTCs, both when considering all patients and when considering only those with bone metastasis. We also found that low red blood cell count was associated with the presence of CTCs, whereas high CA 15-3 tumor marker, high mean corpuscular volume, high white blood cell count and high mean platelet volume associated specifically with CTC clusters. Conclusions In addition to blood count correlatives to single and clustered CTCs, we found that denosumab treatment associates with most patients lacking CTCs from their peripheral circulation. Prospective studies will be needed to validate the involvement of denosumab in the prevention of CTC generation.

Abstract
Lymphangioleiomyomatosis (LAM) is a rare and refractory disease that affects women of reproductive age. Several target therapies are used to manage LAM, but no curative modes of treatment have been reported yet. Therefore, in this study, we focused on targeting human epidermal growth factor receptor (HER) family proteins as a treatment strategy for LAM. In antibody array analysis, HER signaling was detected in the proteins extracted from LAM tissues. We then evaluated the expression of HER family members in 34 pulmonary LAM specimens using both immunohistochemistry and quantitative reverse-transcription polymerase chain reaction. Hierarchical clustering analysis was performed to classify the cases based on the immunohistochemistry results. Both epidermal growth factor receptor (EGFR) and HER4 were expressed in all 34 cases. HER3 was expressed in 25 of 34 cases, but HER2 was not expressed in any case. In addition, results of quantitative reverse-transcription polymerase chain reaction analysis confirmed the expression of EGFR and HER4 expression in LAM cells. Patients with HER3- or HER4-positive tissues were younger and had a history of pneumothorax. The cases were classified into 4 different clusters based on the results of hierarchical cluster analysis. One of these clusters was associated with EGFR, HER3, and HER4; the patients in this cluster were significantly younger and had a history of pneumothorax. These results indicated that HER family could contribute to the progression of pulmonary LAM, and treatments targeted against HER family might be effective for treating pulmonary LAM.
