Exploring the role of trifarotene against RAR-α: an investigation of expression pattern and clinicopathological significance of RAR-α in breast cancer. Front Pharmacol 2024; 15:1361679. [PMID: 38910889 PMCID: PMC11190336 DOI: 10.3389/fphar.2024.1361679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 05/06/2024] [Indexed: 06/25/2024] Open
Abstract
Introduction The members retinoic acid receptors (RARs) (α, β, and γ) and retinoid X receptors (RXRs) (α, β, and γ) belong to the retinoid receptor family. They regulate the biological action of classical retinoids through nuclear retinoid receptors, a transcription factor that is regulated by ligands. Through the binding of particular retinoic acid-responsive elements (RAREs) located in target gene promoters, RARs and members of the RXRs form heterodimers. By binding to its nuclear receptors and triggering the transcription of the target genes downstream, retinoic acid (RA) mediates the expression of certain genes. Retinoids so mainly control gene expression to carry out their biological actions. RARs are essential for many biological processes, such as development, immunity, reproduction, organogenesis, and homeostasis. Apart from their physiological functions, RARs are also linked to pathologies and tumors due to mutations, protein fusions, changes in expression levels, or abnormal post-translational changes that lead to aberrant functions and homeostasis breakdown. The oncogenic development of animal tissues or cultured cells is linked to altered expression of retinoid receptors. The RAR-α is over-expressed in several malignancies. Increased invasion and migration in several cancer forms, including HNSC carcinoma, pediatric low-grade gliomas, lung adenocarcinoma, and breast cancer, have been linked to its upregulated expression. Numerous approved therapeutic regimens targeting RAR-α have been developed, improving patient survival rates. Objective This study's main objective was to identify novel RAR-α-targeting drugs and evaluate the expression patterns of RAR-α in breast cancer patients. Methodology In-silico investigation using a variety of bioinformatics tools like UALCAN, TISCH, TIMER 2.0, ENRICHR, and others were employed to examine the expression of RAR-α. Further we evaluated in-silico inhibition of RAR-α with trifarotene and also tested the cytotoxicity of trifarotene in breast cancer cells. Results Our research indicates that RAR-α is upregulated in several malignancies including Breast Cancer. It regulates granulocyte differentiation and has an association with the retinoic acid receptor signaling pathway and cellular response to estrogen stimulus. Furthermore, trifarotene was found as a potential synthetic compound that targets RAR-α through in silico and in-vitro study. Discussion Overall, this research indicates that elevated expression of RAR-α enhances the onset of breast cancer. Using trifarotene medication to target RAR-α will significantly boost the response of breast cancer individuals to treatment and delay the development of resistance to drugs.

Abstract
Breast cancer management for young Indian women are full of challenges. The National Cancer Registry Programme (NCRP) has predicted that nearly 2,30,000 cases of breast cancer will be reported annually by 2025; with a steady increase in cases of young women (< 45 years of age) with breast cancer. In this review, the available literature is evaluated to understand the various risk factors contributing to the rise in cases of breast cancer in young women in India. Further, the challenges that are faced by the technicians in early diagnosis (e.g., physiology of young breasts, limited trained professionals, and awareness among patients, and cost of the treatment) of breast cancer. This review also focuses on the upcoming diagnostics like serum biomarkers and nanosensors for the early identification of the disease. For better prognosis and to reduce the chances of disease reoccurrence and metastasis, it is important that the disease has to be identified at an early stage.

Abstract
Background In Switzerland, approximately 6000 new breast cancer cases and 1300 deaths are reported annually. Brain metastasis from breast cancer (BMBC) has a major effect on prognosis. This study aimed to identify prognostic factors for overall survival (OS) in a cohort of Swiss patients with BMBC. This study evaluated the prognosis on older BMBC, which has not been completely addressed in the literature. Methods We performed a retrospective chart review analysis with the primary endpoint of OS after a diagnosis of BMBC. The study population was divided into 2 groups based on an OS cut-off value of 12 months after diagnosis. Univariate and multivariate analyses of several risk factors, including age, were performed. To evaluate differences in OS according to age, we performed a secondary analysis to examine the prognostic value of clinical symptoms, metastatic pattern, and lymph node involvement in an older (≥65 years) vs. younger (<65 years) cohort. Results From 1989 to 2019, 55 patients were identified as having BMBC, among whom 47 patients were confirmed to be dead. The median patient age was 58 years (range 25-83 years). Comorbidities were present in 45 (81.8%) patients. The median survival in the OS <12 and OS ≥12 months groups was 4.3 and 30.7 months, respectively (p<0.001). Multivariate analysis revealed no significant differences in terms of comorbidities, medication use, M-stage, and symptomatology between the 2 groups. Additionally, there was no significant difference in OS in the 2 subgroups of patients aged <65 and ≥65 years. Discussion We concluded that age should not be a decisive factor in therapy planning for advanced breast cancer patients with BMBC.

Abstract
Background The use of poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors for breast cancer (BC) therapy is the subject of debate, and there is an urgent need to understand much the expression and prognostic role of the PARP1 protein. In this study, we have compared the expression of PARP between BC and benign breast disease (BBD) patients and also analyzed the association of PARP expression with clinicopathological parameters in BC. Methods The study consists of 30 patients with newly diagnosed operable BC who were planned for surgery without neoadjuvant chemotherapy and 15 patients of BBD as a control between 2019 and 2021. Immunohistochemical analyses were performed prospectively on tissue samples. Anti-human PARP1 rabbit polyclonal antibody gives strong nuclear positivity. Internal control was the adipose tissue and the BBD acted as the external control. PARP1 expression was evaluated using the multiplicative quickscore method. Results The mean age for BC patients was 51.30 ± 10.694 years (range: 25-75 years) while BBD was below 30 years. Overexpression of PARP was present in 25 (83.3%) and weak expression in 5 (16.7%) of BC patients compared to BBD, only 2 (13.3%) patients demonstrated an overexpression of PARP, and 13 (86.6%) patients showed weak expression which showed significant association (P < 0.001). In BC, nuclear PARP (nPARP) overexpression was seen in 22 (73.3%) patients and weak expression of nPARP in 8 (26.7%), whereas 5 (16.7%) patients showed cytoplasmic overexpression. On comparing expression of PARP with clinicopathological parameters, PARP overexpression was significantly associated with older population (age >50 years) (P = 0.002), postmenopausal women (P = 0.029), higher TNM stage (Stage II and III) (P = 0.014), higher histological grade (grade 2) (P = 0.043), and presence of lymphovascular invasion (P = 0.015). Enhanced PARP1 expression is closely correlated with positive estrogen receptor status (P = 0.001) and PR status (P = 0.001). Overall PARP and nPARP overexpression was significantly associated with ER- (P = 0.006 and P = 0.008) and PR-positive (P = 0.006 and P = 0.008) patients. The PARP and nPARP overexpression was significantly associated with nontriple-negative BC patients (P = 0.001 and P = 0.001). Conclusion We have not come across any study in the literature to compare PARP expression in BC and BBD patients. On the basis of our observations, we concluded that PARP overexpression is a poor prognostic marker in BC.

Front Mol Biosci 2021; 8:697922. [PMID: 34235182 PMCID: PMC8255376 DOI: 10.3389/fmolb.2021.697922] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 06/04/2021] [Indexed: 02/05/2023] Open
Abstract
Background: Triple-negative breast cancer (TNBC) is associated with a poor prognosis. Sphingosine-1-phosphate (S1P), a potent sphingolipid metabolite, has been implicated in many processes that are important for breast cancer (BC). S1P signaling regulates tumorigenesis, and response to chemotherapy and immunotherapy by affecting the trafficking, differentiation or effector function of tumor-infiltrating immune cells (TIICs). Objective: In this study, using bioinformatics tools and publicly available databases, we have analyzed the prognostic value of S1P metabolizing genes and their correlation with TIICs in BC patients. Methods: The expression of S1P metabolizing genes and receptors was evaluated by the UALCAN cancer database. The correlation between mRNA expression of S1P metabolizing genes and receptors and survival outcome of breast cancer patients was analyzed by the Kaplan-Meier plotter database. The association between the gene expression and infiltration of immune cells in the tumors was analyzed by "Tumor-Infiltrating Immune Estimation Resource (TIMER). In silico protein expression analysis was done using the Human Protein Atlas" database. Results: TNBC patients with lower expression of S1P phosphatase 1 (SGPP1) or lipid phosphate phosphatase 3 (PLPP3) have much shorter relapse-free survival than the patients with a higher expression of these genes. SGPP1 and PLPP3 expression show a strong positive correlation with tumor-infiltrating dendritic cells (DCs), CD4+ and CD8+ T cells, neutrophils, and macrophages in the TNBC subtypes. In addition, S1P receptor 4 (S1PR4), an S1P receptor exhibit a strong positive correlation with DCs, CD4+ and CD8+ T cells and neutrophils in TNBC. We, therefore, conclude that low expression of SGPP1 and PLPP3 may hinder the recruitment of immune cells to the tumor environment, resulting in the blockage of cancer cell clearance and a subsequent poor prognosis.
