Curcumin-Induced Antitumor Effects On Triple-Negative Breast Cancer Patient-Derived Xenograft Tumor Mice Through Inhibiting Salt-Induced Kinase-3 Protein, Tzu-Chun Cheng, John Oliver Sayseng, Shih-Hsin Tu, Ting-Ching Juan, Chia-Lang Fang, You-Cheng Liao, Cheng-Ying Chu, Hui-Wen Chang, Yun Yen, Li-Ching Chen, Yuan-Soon Ho

Journal of Food and Drug Analysis
This study demonstrated for the first time that curcumin effectively inhibits the growth of triple-negative breast cancer (TNBC) tumors by inhibiting the expression of salt-induced kinase-3 (SIK3) protein in patient-derived xenografted tumor mice (TNBC-PDX). For TNBC patients, chemotherapy is the only option for postoperative adjuvant treatment. In this study, we detected the SIK3 mRNA expression in paired-breast cancer tissues by PCR analysis. The results revealed that SIK3 mRNA expression was significantly higher in tumor tissues when compared to the normal adjacent tissues (73.25 times, n=183). Thus, it is proposed for the first time that the antitumor effect induced by curcumin …
Role Of Autophagy In Acridocarpus Orientalis-Induced Anti-Breast Cancer Activity, Suhib Hisham Ahmed Saeed Altabbal
Role Of Autophagy In Acridocarpus Orientalis-Induced Anti-Breast Cancer Activity, Suhib Hisham Ahmed Saeed Altabbal
Theses
Breast cancer is the most frequently diagnosed cancer in women worldwide. Triple Negative Breast Cancer (TNBC), which lacks the expression of the hormonal Estrogen Receptor (ER) and Progesterone Receptor (PR), and the amplification of Human Epidermal Growth Factor Receptor 2 (HER2), is not responsive to the hormonal therapy. Therefore, chemotherapy and radiotherapy, which cause severe side effects, are the current available choices to treat TNBC. Hence, there is an urgent need to find new therapeutic choices for TNBC. It is estimated that 50% of all drugs in clinical use during the 21st century are natural products and plants derived. …

Manuscripts, Articles, Book Chapters and Other Papers
Triple-negative breast cancer (TNBC) is a subtype of breast cancer that disproportionally accounts for the majority of breast cancer-related deaths due to the lack of specific targets for effective treatments. In this review, we highlight the complexity of the transforming growth factor-beta family (TGF-β) pathway and discuss how the dysregulation of the TGF-β pathway promotes oncogenic attributes in TNBC, which negatively affects patient prognosis. Moreover, we discuss recent findings highlighting TGF-β inhibition as a potent method to target mesenchymal (CD44+/CD24-) and epithelial (ALDHhigh) cancer stem cell (CSC) populations. CSCs are associated with tumorigenesis, metastasis, relapse, resistance, and diminished patient prognosis; …

Molecular Mechanisims Underlying The Anti-Cancer Activity Of Gum Arabic From Acacia Sp. In Triple-Negative Breast Cancer Cells., Sawsan Yaslam Alyafii
Theses
Metastatic breast cancer is the leading cause of cancer-related deaths among women worldwide. Triple-negative breast cancer (TNBC) is the most aggressive, accounting for 15-20% of all breast cancer cases. As TNBC cells lack the expression of hormone receptors estrogen receptors (ER) and progesterone receptors (PR) and human epidermal growth factor receptor 2 (HER2), TNBCs are unresponsive to hormonal therapy and often become highly resistant when exposed to standard chemotherapy, which has been identifies as a major obstacle in TNBC treatment. Gum Arabic, a natural exudate produced from plants, is widely used traditionally for religious, cosmetics as well as medical purposes …

Advancing The Preclinical Development Of Secondary Metabolites From Cacospongia Mycofijiensis For The Treatment Of Cancer, Joseph Morris
Advancing The Preclinical Development Of Secondary Metabolites From Cacospongia Mycofijiensis For The Treatment Of Cancer, Joseph Morris
Natural Sciences and Mathematics | Biological Sciences Master's Theses
The marine sponge Cacospongia mycofijiensis from the Indo-Pacific has proven to be a source of structurally diverse secondary metabolites that are biologically active against a variety of distinct targets. Current interest in the secondary metabolites of C. mycofijiensis largely stems from a) their potent and preferential cytotoxicity for cancer cell lines versus normal cells, making many of them promising leads as cancer therapeutics and b) the novel mechanisms of action responsible for their impressive cytotoxicity. However, limited compound availability has resulted in a paucity of studies aimed at advancing the preclinical development of these secondary metabolites from C. mycofijiensis for …

Chemotherapy is the main treatment for triple-negative breast cancer (TNBC), a subtype of breast cancer that is aggressive with a poor prognosis. While chemotherapeutics are potent, these agents lack specificity and are equally toxic to cancer and nonmalignant cells and tissues. Targeted therapies for TNBC treatment could lead to more safe and efficacious drugs. We previously engineered a breast cancer cell targeting peptide 18-4 that specifically binds cell surface receptor keratin 1 (K1) on breast cancer cells. A conjugate of peptide 18-4 and doxorubicin (Dox) containing an acid-sensitive hydrazone linker showed specific toxicity toward TNBC cells. Here, we report the …
The Effect Of Breastfeeding Education In African American Women On Initiation And Duration Of Breastfeeding, Shalawn F. Harris
The Effect Of Breastfeeding Education In African American Women On Initiation And Duration Of Breastfeeding, Shalawn F. Harris
Electronic Theses and Dissertations
Abstract
This Doctor of Nursing Practice scholarly project aimed to evaluate the effectiveness of breastfeeding education in African American women on the initiation and duration of breastfeeding. Studies demonstrated that breastfeeding education by providers and a breastfeeding support network positively influenced breastfeeding initiation and continuation in African American women. Breastfeeding education containing information on the decreased risk of breast cancer in African American women may be an even greater motivator for breastfeeding. Participants for this project were African American women, ages 18–50, in their last trimester of pregnancy. The project was approved to be implemented at an urban clinic in …

Journal of Food and Drug Analysis
Triple-negative breast cancers (TNBCs) lack specific targeted therapy options and have evolved into highly chemo-resistant tumors that metastasize to multiple organs. The present study demonstrated that the proline dehydrogenase (PRODH) mRNA level in paired (tumor vs. normal) human breast tissue samples (n=234) was 6.6-fold greater than normal cells (*p=0.021). We established stable PRODH-overexpressing TNBC (HS578T) cells, and the malignant phenotypes were evaluated using soft agar colony formation and Transwell migration assays. The results demonstrated that PRODH induced epithelial-mesenchymal transition in cancer cells and increased cell proliferation. The present study found that the tea polyphenol epigallocatechin-3-gallate (EGCG) significantly inhibited …

Targeting a tumor’s metabolic dependencies is a clinically actionable therapeutic approach; however, identifying subtypes of tumors likely to respond remains difficult. The use of lipids as a nutrient source is of particular importance, especially in breast cancer. Imaging techniques offer the opportunity to quantify nutrient use in preclinical tumor models to guide development of new drugs that restrict uptake or utilization of these nutrients. We describe a fast and dynamic approach to image fatty acid uptake in vivo and demonstrate its relevance to study both tumor metabolic reprogramming directly, as well as the effectiveness of drugs targeting lipid metabolism. Specifically, …
