Although gonadotropin-releasing hormone agonists (GnRHa) have been used in the therapy of the endocrine-dependent cancers, their biological mechanism remained obscure. We have studied the roles of mitogen-activated protein kinase family in the antiproliferative effect of GnRHa on the Caov-3 human ovarian cancer cell line. Reverse transcription-PCR assays confirmed mRNA for GnRH receptor in Caov...

Interferons, in addition to their antiviral activity, induce a multiplicity of effects on different cell types. Interferon (IFN)-gamma exerts a unique regulatory effect on cells of the mononuclear phagocyte lineage. To investigate whether the antiviral and antiproliferative effects of IFN-gamma in macrophages can be genetically dissociated, and whether IFN-alpha and IFN-gamma use the same cellu...

The last one and half a decade witnessed an outstanding re-emergence of attention and remarkable progress in the field of protein methylation. In the present article, we describe the early discoveries in research and review the role protein methylation played in the biological function of the antiproliferative gene, BTG2/TIS21/PC3.

Caralluma europaea is a medicinal plant used in Morocco to cure variety of illnesses. This study was conducted determine the chemical composition, antioxidant, antiproliferative, anti-inflammatory, and wound healing activities C. lipids. The composition analyzed using time-of-flight mass spectrometry high-performance liquid chromatography. antioxidant potential determined 2,2-di-phenyl-1-picryl...

Runx3, a member of Runt-related transcription factor (Runx) proteins with tumor suppressor effect, is a tissue–restricted and cancer related transcription factor that regulate cell proliferation and growth, as well as differentiation. In the present study, exogenous Run3 was transiently expressed in AGS (human gastric adenocarcinoma), with undetectable Runx3 protein and in A549 (human lung carc...

OBJECTIVE To investigate the potential therapeutic effects of adenovirus expressing IFN-λ1 and IFN-λ2 (Ad/hIFN-λ) in treating squamous cell carcinoma of the oral tongue (SCCOT) and to explore the underlying mechanisms. METHODS Two SCCOT cell lines HSC-3 and Tca8113 were adopted as study objects. Cell Counting Kit-8 (CCK-8) cell proliferation and viability assay was performed to evaluate the a...

A series of novel indole derivatives were designed, synthesized and evaluated for the binding affinity Bcl-2 family proteins antiproliferative activity against three selected cancer cell lines (PC-3, Jurkat, MDA-MB-231). The preliminary structure-activity relationship (SAR) this scaffold was summarized. Among all compounds, compound 9k showed best inhibitory Mcl-1 with IC50 values 7.63 µM 1.53 ...

Polyamines are small cationic molecules required for cellular proliferation. Agmatine is a biogenic amine unique in its capacity to arrest proliferation in cell lines by depleting intracellular polyamine levels. We previously demonstrated that agmatine enters mammalian cells via the polyamine transport system. As polyamine transport is positively correlated with the rate of cellular proliferati...

The drug accumulation of a human multidrug resistance 1 (mdr1) gene-transfected mouse lymphoma cell line and a multidrug resistance protein (MRP)-expressing human breast cancer cell line MDA-MB-231 was compared in the presence of sixteen flavonoids and five isoflavonoids. The expression of the 170-kDa P-glycoprotein (P-gp) (MDR1) and 190-kDa multidrug resistance protein (MRP) in both cell lines...

Silibinin, a naturally occurring flavonoid antioxidant found in the milk thistle, has recently been shown to have potent antiproliferative effects against various malignant cell lines, but the underlying mechanism of action remains to be elucidated. We investigated the effect of silibinin on androgen-independent prostate cancer PC-3 cells. At pharmacologically achievable silibinin concentration...
