A recombinant analogue of lactaptin (RL2), a new potential anticancer molecule, induces apoptosis in cultured tumor cells. The tumor suppression efficacy of RL2 was shown against mouse hepatoma-1 cells and MDA-MB-231 human breast adenocarcinoma cells. The RL2-based therapeutic drug lactaptin is distributed evenly throughout the organism, which reduces its antitumor efficacy. In the current stud...

BACKGROUND Tumor cell expression of Toll-like receptors (TLRs) can promote inflammation and cell survival in the tumor microenvironment. Toll-like receptor 4 (TLR4) signaling in tumor cells can mediate tumor cell immune escape and tumor progression, and it is regarded as one of the mechanisms for chronic inflammation in tumorigenesis and progression. The expression of TLR4 in human breast cance...

conclusions our findings showed that the genotype tt rs53576 oxtr, as well as t allele had significant differences in our population and play a protective role. therefore, it is suggested to place more interest on these oxtr in large populations and different ethnic groups. results the logistic regression analysis suggested no significant associations of oxtr single nucleotide polymorphism (snp...

In the present study, marine crab Portunuspelagicus was screened with 17 primers and made to score polymorphism. The main emphasis of study assess genetic diversity at intra specific level among 3 accessions P. pelagicus species Gulf Mannarusing RAPD markers. analysis shows that there is a high polymorphism different accessions. From this it understood each location varied respect environmental...

Curcuma is historically problematic to identify and clear their relationships for cultivar variety appearance commonly in China. Sequence-Related Amplified Polymorphism (SRAP) marker was used detect genetic among 10 China’s endemic herbs including three Chinese rarely species firstly (C. amarissima, C. flaviflora C. yunnanensis). The 2-35 polymorphic ba...

While we previously demonstrated that CITED2 expression in primary breast tumor tissues is elevated relative to normal mammary epithelium and inversely correlated with patient survival, its functional impact on primary tumor development and progression remained unknown. To address this issue, we examined the effect of CITED2 silencing on the growth of human breast cancer cell lines MDA-MB-231 a...

Clusterin/apolipoprotein J (Clu) is a ubiquitously expressed secreted heterodimeric glycoprotein that is implicated in several physiological processes. It has been reported that the elevated level of secreted clusterin (sClu) protein is associated with poor survival in breast cancer patients and can induce metastasis in rodent models. In this study, we investigated the effects of sClu inhibitio...

UNLABELLED Copper is an essential cofactor for a variety of biochemical processes including oxidative phosphorylation, cellular antioxidant activity, and elimination of free radicals. The copper transporter 1 is known to be involved in cellular uptake of copper ions. In this study, we evaluated the utility of human copper transporter 1 (hCTR1) gene as a new reporter gene for (64)Cu PET imaging....

Objective(s) Curative treatment of breast cancer patients using chemotherapy often fails as a result of intrinsic or acquired resistance of the tumor to the drug. ERK is one of the main components of the Ras/Raf/MEK/ERK cascade, which mediates signal from cell surface receptors to transcription factors to regulate different gene expression. In this study, cytotoxicity and the expression of Erk...

BACKGROUND Our previous study demonstrated that an up-regulation of the Brain-Derived Neurotrophic Factor (BDNF) signaling pathway is involved the mechanism causing the recurrence of triple negative breast cancer. The aim of this study is to investigate the effects of commonly used Chinese medicinal herbs on MDA-MB-231 and HUVEC cells and how they interact with BDNF. METHODS Human TNBC MDA-MB...
