Introduction Breast cancer is an important cause of death in women with prevalence increasingwithage[1].Hormonereceptorstatusisone of a. The link between cancer and altered metabolism is not new, as many observations made during the early period of cancer biology research identified metabolic changes as a common feature of cancerous tissues (such as the Warburg effect; discussed below) 7. As much of the work in the field to date has focused on rapidly prolif-File Size: KB.

  Estrogen receptor-positive MCF-7 human breast cancer cells were cultured with or without various concentrations of the test compounds. The concentration required to inhibit cell proliferation by 50% was determined as measured by the incorporation of [3 H]thymidine into DNA. The experiments were done in triplicate, and the results are averages of three by:   Although previously unknown in human lung cancer, PC activation was recently reported in hepatic tumors in rat and in estradiol-stimulated breast cancer cells. PC expression or suppression has also been respectively associated with enhanced metabolism/proliferation of mammalian cells [ 41 ] or inhibition of tumor cell growth [ 42 ].Cited by:

Introduction. The long-term survival rate among patients with breast cancer across Europe is >70% ().This rate is, in part, due to the widespread use of post-surgery adjuvant anthracycline-based chemotherapy to treat early-stage breast cancer to reduce the risk of relapse and mortality ().The major anthracycline chemotherapeutic reagent is doxorubicin (DOX), a Streptomyces by: 2. cycle progression and tumor growth in MDA-MB human breast cancer cells. However, it is not clear whether this compound exerts other anticancer effects. The results demostrated that synthetic Cam B can inhibit the anchorage-independent growth of MDA-MB breast cancer cells.

Effects of amiodarone, cyclosporin A, and PSC on the cytotoxicity of mitoxantrone, doxorubicin, and vincristine in non-P-glycoprotein human small cell lung cancer cell lines. The mechanism underlying the differential cytotoxicity of curcumin in various cancer types, however, remains largely unclear.

The aims of this study is to examine the concentration- and time-related effects of curcumin on two different breast cancer cells, MCF-7 and MDA-MB, and investigated the functional changes induced by curcumin treatment, as well as their relationship to the Cited by: Human breast cancer MCF-7 cells, obtained from Chinese Academy of Sciences cell library, were cultured in Dul- becco’s modified Eagle’s medium (Hyclone, Thermo Sci.

(HE, HE and HE) on MCF-7 human breast cancer cells. Material and Methods: MCF-7 cells were treated with different concentrations of piperine derivatives (0 Œ 10 μM) during 24h after 48h of cell seeding ( cells/mL).

Results and Discussion: Cell viability assay with MTT, showed that cell growth was dose dependent. However, studies investigating the effect of chemotherapy on the metabolism of breast cancer cells are still limited.

We used 1 H high-resolution magic angle spinning (HR-MAS) NMR spectroscopy to study the metabolic profile of human breast cancer MDA-MB cells either untreated (control) or treated with tamoxifen, cisplatin, and by: 7.

It was found that the IC 50 values of ADR to MCF-7 cells were much lower than those to MCF-7/ADR cells and the values decreased with the treating time extension. GQ reduced the IC 50 of ADR to both cell lines, but its effect on MCF-7/ADR cells was much stronger than that on MCF-7 cells (Fig.

Differences in energy metabolism between normal and cancer cells are reported andalterations in cellular bioenergetics are one of the hallmarks of cancer [].The general principles of metabolic control analysis can be effective for cancer management as abnormal energy metabolism and biological disorder are characteristics of tumors [].In line with this, increased aerobic glycolysis and elevated Cited by: 9.

Tumor therapy mainly attacks the metabolism to interfere the tumor's anabolism and signaling of proliferative second messengers. However, the metabolic demands of different cancers are very heterogeneous and depend on their origin of tissue, age, gender and other clinical parameters.

Gastric cancer (GC) is one of the most common human cancers and the second leading cause of cancer-related mortality worldwide ().The major cause of death is metastasis, which greatly hinders treatment success ().Human gastric cancer tissue contains cancer initiating cells (CIC) ().CIC are defined as the unique subpopulation in the tumors that possess the ability to initiate Cited by: 2.

We found that ΔFosB increased the expression of MMP-9 in MCF-7 breast cancer cells. ΔFosB overexpression in MCF-7 cells increased cellular viability and decreased cell apoptosis.

Alcohol consumption is a risk factor for breast cancer. Little is known regarding the mechanism, although it is assumed that acetaldehyde or estrogen mediated pathways play a role.

We previously showed that long-term exposure to mM ethanol (blood alcohol ~%) of MCFA, a human normal epithelial breast cell line, induced epithelial.karyotype contractions (KC) allow cancer cells to support fewer chromosomes, increase their proliferation rate and acquire the phenotype of a stable, growing tissue similar to stem cells.

Hyperploid cancer cells can expand or contract their karyotypes through rapid mechanisms of endo-reduplication or chromosome : Ying Li.Numerous transcriptomics and cistromics studies were done to investigate estrogen signaling and gene regulation in breast cancer cells, including MCF7 cells 2, In this study, for the first time, we added metabolomics data and tried to infer metabolic networks that are directly regulated by .
