Findings from Taipei Tzu Chi Hospital Advance Knowledge inBreast Cancer (Breast Cancer with Increased DrugResistance, Invasion Ability, and Cancer Stem Cell Propertiesthrough Metabolism Reprogramming).Date: Dec. 1, 2022 From: Women’s Health WeeklyPublisher: NewsRX LLCDocument Type: Article Length: 537 words
Full Text: 2022 DEC 1 (NewsRx) — By a News Reporter-Staff News Editor at Women’s Health Weekly — A new study on breast cancer is nowavailable. According to news reporting originating from the Taipei Tzu Chi Hospital by NewsRx correspondents, research stated,”Breast cancer is a heterogeneous disease, and the survival rate of patients with breast cancer strongly depends on their stage andclinicopathological features. Chemoradiation therapy is commonly employed to improve the survivability of patients with advancedbreast cancer.”
Funders for this research include Ministry of Science Technology; Taipei Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation.
The news editors obtained a quote from the research from Taipei Tzu Chi Hospital: “However, the treatment process is oftenaccompanied by the development of drug resistance, which eventually leads to treatment failure. Metabolism reprogramming hasbeen recognized as a mechanism of breast cancer resistance. In this study, we established a doxorubicin-resistant MCF-7 (MCF-7-D500) cell line through a series of long-term doxorubicin in vitro treatments. Our data revealed that MCF-7-D500 cells exhibitedincreased multiple-drug resistance, cancer stemness, and invasiveness compared with parental cells. We analyzed the metabolicprofiles of MCF-7 and MCF-7-D500 cells through liquid chromatography-mass spectrometry. We observed significant changes in 25metabolites, of which, 21 exhibited increased levels (>1.5-fold change and * * p* * < 0.05) and 4 exhibited decreased levels (<0.75-fold change and * * p* * < 0.05) in MCF-7 cells with doxorubicin resistance. These results suggest the involvement of metabolismreprogramming in the development of drug resistance in breast cancer, especially the activation of glycolysis, the tricarboxylic acid(TCA) cycle, and the hexamine biosynthesis pathway (HBP).”
According to the news editors, the research concluded: “Furthermore, most of the enzymes involved in glycolysis, the HBP, and theTCA cycle were upregulated in MCF-7-D500 cells and contributed to the poor prognosis of patients with breast cancer. Our findingsprovide new insights into the regulation of drug resistance in breast cancer, and these drug resistance-related metabolic pathwayscan serve as targets for the treatment of chemoresistance in breast cancer.”
