Intratumoral hypoxia is a poor prognostic factor associated with reduced disease-free survival in many cancer types, including breast cancer. Hypoxia encourages tumor cell proliferation, stimulates angiogenesis and lymphangiogenesis, and promotes epithelial-mesenchymal transition and metastasis.
Cadmium is a heavy metal posing severe risks and destructive effects on human health. Although cadmium was classified as a human carcinogen, it has been also shown to be a cytotoxic agent that induces cell death either by necrosis or apoptosis. In this study, we investigated the protective role of
OBJECTIVE
Breast cancer survivors in adjuvant therapy, frequently experience the estrogen deficiency with genitourinary symptoms mostly represented by recurrent bacterial cystitis. The objective of the present study was to evaluate the effectiveness of N-acetylcysteine, D-mannose and Morinda
High oxidative stress as defined by hydroxyl and peroxyl activity is often found in the stroma of human breast cancers. Oxidative stress induces stromal catabolism, which promotes cancer aggressiveness. Stromal cells exposed to oxidative stress release catabolites such as lactate, which are up-taken
Purpose: The aim of the current study was to evaluate the effect of N-acetylcysteine (NAC) on the incidence and severity of paclitaxel-induced peripheral neuropathy (PIPN) in breast cancer patients.
Breast cancer is a great public health problem. It remains unclear how pharmorubicin induces cardiac dysfunction in patients with breast cancer. Our study was aimed to explore the influence of pharmorubicin on the left ventricular ejection fraction (EF) of patients with breast cancer A growing number of studies indicate that breast cancer initiation is related to abnormal estrogen oxidation to form an excess of estrogen-3,4-quinones, which react with DNA to form depurinating adducts and induce mutations. This mechanism is often called estrogen genotoxicity. 4-Catechol estrogens,
Malignant cells are highly dependent on aerobic glycolysis, which differs significantly from normal cells (the Warburg effect). Interference of this metabolic process has been considered as an innovative method for developing selective cancer therapy. A recent study demonstrated that the glycolysis
A novel plant sesquiterpene lactone derivative, DET derivative (DETD)-35, originating from parental deoxyelephantopin (DET) was previously observed to effectively suppress human triple negative breast cancer (TNBC) MDA-MB-231 cell activity and tumor growth in mice. In this study, the mechanisms
Cambogin is a polycyclic polyprenylated acylphoroglucinol (PPAP) from the Garcinia genus, which has been used traditionally for cancer treatment across Southeastern Asia. In this study, we found that cambogin inhibited breast cancer cell proliferation and induced cell apoptosis in vitro. Cambogin
Continuous exposure of breast cancer cells to adriamycin induces high expression of P-gp and multiple drug resistance. However, the biochemical process and the underlying mechanisms for the gradually induced resistance are not clear. To explore the underlying mechanism and evaluate the anti-tumor
Baicalein (5,6,7-trihydroxyflavone) (1) has been found to be active against a wide variety of cancer cells. However, the molecular mechanism underlying the effects of 1 on the induction of Ca(2+) movement and cytotoxicity in human breast cancer cells is unknown. This study examined the relationship
The synthetic retinoid N-(4-hydroxphenyl) retinamide (4HPR) has manifold actions, which may contribute to its chemopreventive effects on breast cancer cell growth and progression. A role for ceramide as a stress-response signal is investigated here during the cytotoxic action of 4HPR in MCF-7 cells.
Calcitriol, the hormonal form of vitamin D, enhanced TNF-induced cytotoxicity in MCF-7 breast cancer cells. It increased the induction of caspase-3-like activity and TNF-induced caspase-independent cytotoxicity in the presence of a pan-caspase inhibitor. The antioxidants N-acetylcysteine,
OBJECTIVE
To evaluate the mechanism for enhancing cell death induced by microwave ablation (MWA) combined with doxorubicin treatment in breast cancer cells.
METHODS
Different temperatures of heat treatment were used to mimic the tumor affected by sublethal heat during MWA in vitro. Breast cancer
