Tumor-suppressor microRNA-151-5p regulates the growth, migration and invasion of human breast cancer cells by inhibiting SCOS5.

This study was designed to investigate the role and therapeutic implications of miR-151-5p in breast cancer. The results of the present study revealed that miR-151-5p is significantly downregulated in breast cancer tissues and cell lines. Overexpression of miR-151-5p in SK-BR-3 and CAMA-1 cells inhibits their proliferation and colony formation. Wound heal and transwell assays showed that miR-151-5p inhibits the migration and invasion of the SK-BR-3 and CAMA-1 breast cancer cells. TargetScan analysis followed by the dual luciferase assay confirmed SOCS5 to be the target of miR-151-5p in breast cancer. The expression of SOCS5 was upregulated in all the breast cancer tissues and cell lines. Silencing of SOC5 caused significant inhibition in the proliferation, migration and invasion of the SK-BR-3 cells. Nonetheless, overexpression of SCOS5 could avoid the growth inhibitory effects of miR-151-5p on the breast cancer cells. To conclude, miR-151-5p acts as a tumor suppressor in breast cancer and may exhibit therapeutic implications. PMID: 31934285 [PubMed]

However, these patients often simultaneously show a poor response to cytotoxic drugs, and thus the detailed mechanism of this resistance needs to be further investigated. Our previous research indicated th...

Conclusion EORTC criteria and PERCIST had early predictive value to long-term outcome, but moderate value for pCR. Furthermore, PERCIST might show more potential than the EORTC criteria and conventional PET-based parameters to predict prognosis in breast cancer patients following two cycles of neoadjuvant chemotherapy.

This article reviews current data and ongoing research on atezolizumab for the treatment of breast cancer. Results of atezolizumab monotherapy trials in the context of other early immune checkpoint blockade trials in breast cancer are discussed as well as data from combination clinical trials with chemotherapy in both early stage and metastatic breast cancer. We focus on the safety and efficacy analyses from the phase III IMpassion trial that led to FDA and EMA approval of atezolizumab and nab-paclitaxel in patients whose tumor tested positive for PD-L1 by the Ventana SP142 companion diagnostic immunohistochemical assay.Ex...

AbstractFungating breast cancer (FBC) is a rare entity in developed nations. But this occurrence is not uncommon in our country. The aim of this study was to review clinico-pathologic profile and outcomes of FBC in a developing country. This retrospective study consisted of patients with FBC managed at our institute (Jan 2005 –Dec 2015). Clinico-pathologic profile, management details, and outcomes were analyzed. The Kaplan-Meier method was used to determine overall survival (OS). Log-rank test was performed to compare survival in various subgroups. Seventy-nine patients were detected to have FBC constituting 3.3% of ...

In this study, we evaluated the changes in BMD according to adjuvant treatment in premenopausal women with breast cancer.MethodsBetween 2006 and 2010, BMD data of 910 premenopausal women with breast cancer before operation and 1, 2, 3.5, and 5  years post-operation were retrospectively analyzed. The patients were divided according to the type of treatment: observation (O), tamoxifen (T), chemotherapy (C), C followed by T (C → T), and gonadotropin-releasing hormone (GnRH) agonist with T (G + T).ResultsAfter 5  years of follow-up, BMD changes were similar between the T and O groups ...

Authors: Garufi G, Palazzo A, Paris I, Orlandi A, Cassano A, Tortora G, Scambia G, Bria E, Carbognin L Abstract Introduction: Despite recent advances in the molecular characterization of triple-negative breast cancer (TNBC), the standard treatment for early-stage TNBC is represented by the historically used anthracycline and taxane-based chemotherapy. In this modern era of precision medicine, several new therapeutic strategies and novel agents have been investigated in the neoadjuvant setting of TNBC, in order to individualize treatment.Areas covered: This review provides a comprehensive overview of the currently a...
