flavone/悪性腫瘍

The serine-threonine kinase CK2, which targets over 300 cellular proteins, is overexpressed in all cancers, presumably reflecting its ability to promote proliferation, spread, and survival through a wide range of complementary mechanisms. Via an activating phosphorylation of Cdc373, a co-chaperone

Polymethoxylated flavones (PMFs) from citrus fruits are reported to present anticancer potential. However, there is a lack of information regarding their effect on cancer stem cell (CSC) populations, which has been recognized as responsible for tumor initiation, relapse, and chemoresistance. In this

A rat tumour (MC7 sarcoma), growing subcutaneously, has been shown to be sensitive to a single application of flavone acetic acid. Thirteen rats were still alive after 50 days and 8 of these were tumour free, as compared with control rats which survived for 15.7 +/- 2.53 days. The 8 tumour free

Flavone acetic acid (FAA), a new drug with broad activity against transplanted solid tumors of mice, induces nonrepairable DNA single strand breaks that correlate with therapeutic efficacy. To test the hypothesis that the inability of the cells to repair single strand breaks is associated with a

Phlomis bruguieri (P. bruguieri) is a large genus in the Lamiaceae family, with a wide variety distributed in Euro-Asia, Central Asia, Iran, and China. Phlomis flowers have been used as herbal tea for gastrointestinal disturbances, protection of liver and cardiovascular systems. The aim of this

BACKGROUND Dietary flavone was previously shown to increase the expression of deleted in liver cancer-1 gene (DLC-1) in HT-29 colon carcinoma cell line [Herzog A, Kindermann B, Doring F, Daniel H, Wenzel U. Pleiotropic molecular effects of the pro-apoptotic dietary constituent flavone in human colon

OBJECTIVE To observe the effects of flavone from leaves of Diospyros kaki on expression of apoptosis signal-regulating kinase 1 (ASK1) and rat vascular smooth muscle cells (VSMCs) proliferation by tumor necrosis factor alpha in vitro. METHODS Rat aortic VSMCs were cultured in vitro and treated with

Over 4000 flavonoids have been identified so far and among these, many are known to have antitumor activities. The basis of the relationships between chemical structures, type and position of substituent groups and the effects these compounds exert specifically on cancer cells are not completely

OBJECTIVE Oral squamous cell carcinoma (OSCC) is one of the most common head and neck cancers with a poor prognosis due to frequent lymph node metastasis and local invasion. A growing number of in vitro studies have been conducted on the potential anticancer activity of flavonoids in various cancer

Treatment of human umbilical vein endothelial cells with flavone acetic acid (FAA) at 800 micrograms/ml for 4 h resulted in a 3-11-fold increase in procoagulant activity. This increase was due to enhanced tissue factor expression on the endothelial cell surface, as evidenced by the blocking of the

Having observed that tumor necrosis factor (TNF)-alpha and doxorubicin (DXR) produce a synergistic inhibition of melanoma B16 and also of its multidrug resistant (MDR) variant in vitro, we tested whether this interaction would occur in vivo as well. C57BL/6 mice with s.c. tumors were treated with

Previous studies using murine tumours have shown enhanced action of certain chemotherapeutic compounds when combined with agents that reduce tumour blood flow. In the majority of cases the compounds used were cytotoxic to the induced hypoxic cells but in this study we have investigated the relative

Dietary flavonoids have been shown to exert specific cytotoxicity toward some cancer cells, but the precise molecular mechanisms are still not completely understood. In this study, cytotoxic effects of flavones (apigenin and luteolin) on two different cancer cell lines, including human chronic

Tumor initiation, progression and resistance to therapies are tightly associated with over-expression of anti-apoptotic proteins Bcl-2, Bcl-x(L), Bcl-w and Mcl-1. ABT-263 (Navitoclax), an orally bio-available small-molecule mimetic of the Bcl-2 homology domain 3, inhibits Bcl-2, Bcl-x(L), and Bcl-w

Flavone compound is a polyphenolic compound widely existing in plants and has an extensive biological activity. In recent years, it has been found to have a significant anti-cancer effect, as in combating cell proliferation, inducing cell apoptosis, interfering with cellular signal transduction,
