abstract background: the aims of this study were to assay the activity of adenosine deaminase (ada) in estrogen receptor positive (mcf-7) and negative (mda-mb468) breast cancer cell lines. methods: mda-mb468 and mcf-7 breast cancer cell lines were cultured in complete medium, striped serum with and without 0.0 1~-lm diethylstilbestrol (des), complete medium in the presence and absence of 111m t...
background & aim:breast cancer is the second most common cancer in women after lung cancer. given that the herbal ingredients are used for centuries to treat cancer,the aim of this study was to determine the cytotoxic effect of hydroalcholic extract from thymus daenesiscelak on mcf-7 cancer cells line. experimental: breast cancer cells mcf-7 and natural fibroblast cells were cultured in dmem me...
We report the characterization of the virus produced by a lymphoid cell line derived from a lymphoma of an AKR mouse after injection of the polytropic AKR virus MCF-247. The virus displays polytropic host range properties and is indistinguishable from MCF-247 as judged by analysis of the large RNase T1-resistant oligonucleotides of the RNA genome. Restriction enzyme analysis of cellular DNA rev...
We performed near-diffraction limited two-photon fluorescence (TPF) imaging through a lensless, multicore-fiber (MCF) endoscope utilizing digital phase conjugation. The phase conjugation technique is compatible with commercially available MCFs with high core density. We demonstrate focusing of ultrashort pulses through an MCF and show that the method allows for resolution that is not limited by...
Abstract We discuss general structural features of the Banning and Mission Creek strands (BF MCF) southern San Andreas fault (SSAF) in Coachella Valley, based on ambient noise earthquake wavefields recorded by a seismic array with >300 nodes. Earthquake P arrivals show rapid changes waveform characteristics over 20–40 m zones that coincide surface BF MCF. These variations indicate MCF ar...
We have examined the effect of two small interference RNA against Jnk-1 and Jnk-2 in the breast cancer cell line MCF-7. The expression of the JNK-1 and JNK-2 is frequently elevated in breast cancer and is a frequent genetic abnormality in this malignancy. For a better understanding of its role in maintaining the malignant phenotype, we used small RNA interference (siRNA) directed against Jnk-1 ...
Epoxyeicosatrienoic acid (EET) production via cytochrome P450 (CYP) epoxygenases closely correlates with the progression of breast cancer. However, its role in the development of chemoresistant breast cancers has yet to be elucidated. Here, we found that CYP3A4 expression and its epoxy-product, 11,12-epoxyeicosatrienoic acid (11,12-EET) was enhanced in tamoxifen (TAM)-resistant MCF-7 (TAMR-MCF-...
Multicast is designed to jointly deliver content from a single source to a set of destinations; hence, it can efficiently save the bandwidth consumption and reduce the load on the source. In many important applications, the appearance of multiple sources brings new opportunities and challenges to reduce the bandwidth consumption of a multicast transfer. In this paper, we focus on such type of m...
Montane cloud forest (MCF) has high levels of species diversity, contributes positively to the catchment water yield, and is a globally threatened habitat type. The shortage of reliable data regarding the area currently occupied by MCF remains an obstacle to operational conservation planning in Mexico. This paper assesses how much MCF remains in the central Highlands of Chiapas (Mexico) and how...
GSTP1, encoding the pi-class glutathione S-transferase, is commonly inactivated by somatic CpGisland hypermethylation in cancers of the prostate, liver, and breast. We report here thathypermethylation of CpG dinucleotides at the 5' transcriptional regulatory region was sufficient to inhibit GSTP1 transcription in MCF-7 breast cancer cells and that repression of GSTP1 transcription was mediated ...
