ed GnRH analogue. The cells do not accumulate 3H inositol phosphates after treatment c-Met Signaling Pathway with triptorelin. Transfected fa Stable breast cell lines with GnRH receptor functional model for the GnRH-positive breast cancer can be generated, exp HNT cell lines were the top with a GnRH receptor expression of transfected cDNA construct into pcDNA3.1 neo and G418-resistant cells were cloned. At least three Strength G418-resistant clones from each cell line were on the expression of GnRH receptors sieved with the binding assay and in accordance with their relative levels of receptor detectable on the cell Surface. The relative values of the specific binding of repr Sentative clones identified are shown in Figure 2A. A clone expressing high SVCT GnRH receptor on the cell Surface.
About 50% of transfected MCF-7 clones had moderate levels of specific GnRH binding. A 75 ZR 1-transfected cell clones U Erte and m Pure high specific GnRH binding. Vinorelbine A 30-transfected MDA MB expressed 231clones high GnRH receptor, but not T47D transfected clones showed GnRH binding. MCF 7hygro 14 cells were prepared from MCF-7 cells by cloning 30 st by transfection with a promoter fragment gene and hygromycin resistance again followed by cloning into further subcloned. Among these clones, MCF had 7hygro14 h HIGHEST GnRH receptor cell surface Surface. Analysis of the integration site of the gene for resistance to hygromycin, with restriction endonuclease excision, circularization of DNA, wherein the inverse PCR cloning and sequences Age of DNA, insertion immediately 5, the CMV promoter directs transcription of the GnRH receptor in the rat cDNA in MCF 7hygro14.
In all other clones 7hygro MCF study the hygro gene was inserted at c Tee of three, side of the GnRH receptor of the rat cDNA. Levels of GnRH receptor on the cell surface were Surface SVCT 2, MDA MB231 and MCF 7hygro14 34 Similar levels of transfected F Stable HEK293 cells Prostate WPE described an 8-cells elsewhere NB26. The presence of GnRH receptors functional in these clones was best determined by measuring the production of phosphate 3Hinositol after the addition of triptorelin CONFIRMS. SVCT 2, MCF 7hygro14 and MDA-MB 231 cells express the GnRH receptor of the rat produced high levels of inositol phosphates 3H after GnRH receptor activation, that correlates with the H Height of receptor expression.
MDA MB 231 cells showed high basal 34 phospholipase C activity of t, the dynamics of accumulation of inositol phosphate after GnRH receptor activation were in various cell lines, but differences in sales after the activation of cell receptors provided removalGnRH were an incubated serum-free medium overnight before stimulation. In the presence of serum, the GnRH receptor activation does not significantly affect the levels of p ERK1 / 2 Levels of p ERK1 / 2 not by GnRH receptor activation in serum starved MDA-MB231 cells 34 VER Changed. Treatment of cells with MCF 7hygro14 15 20 M IR-II inhibitor IGF entered Not fast f Filled and stable p ERK1 / 2 in the presence of serum. The inhibitor does not elicit this effect in MDA-MB 231 cells 34th If the inhibitor is washed away by MCF 7hygro14 cells after exposure for 1 h by addition of serum-containing medium, followed, there was a rapid hypno
