Antun sente ml5/5/2023 Due to high volumes of spamming and progression of online communication clutter, some practitioners began to question the usability of e-mail as a marketing communication channel, while others embarked on working on improving the message itself. From the very beginning of Internet utilization for business purposes, e-mail was one of the most widely used communication techniques in B2B and B2C markets alike. Design/Methodology/Approach – E-mail marketing techniques have been a substantial part of e-marketing methodology since the early Internet days of the mid-1990s. Open-Rate Controlled Experiment in E-Mail Marketing Campaignsĭirectory of Open Access Journals (Sweden)įull Text Available Purpose – The main purpose of this paper is to test the controlled experiment (A/B split methodology in B2C oriented e-mail marketing campaigns. To remove them it may be necessary to re-install the Windows software on your PC. They can enter your system when you open an attachment. Some of these so called 'Trojan horses' can conceal themselves in very attractive pictures and funny slide shows.On the PC Windows infrastructure, CERN runs software to protect users from known viruses, but new ones can sometimes arrive before our software recognises them. Attachments that are apparently harmless might hide active content producing nasty effects as soon as they are opened. These data provide new evidence that further strengthens the important nature of COUP-TFII in steroidogenesis, androgen homeostasis, cellular defense, and differentiation in mouse Leydig cells.Īn in-depth high-throughput transcriptomic analysis of COUP-TFII-depleted Leydig cells reveals novel gene pathways and networks regulated by this orphan nuclear receptor.Following the recent e-mail viruses you are asked to be cautious when opening e-mail attachments on your PC. Finally, analysis of the Gsta3 and Inha gene promoters showed that at least two of the downregulated genes are potentially new direct targets for COUP-TFII. Downregulated genes included hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 1 (Hsd3b1), cytochrome P450, family 11, subfamily a, polypeptide 1 (Cyp11a1), prolactin receptor (Prlr), nuclear receptor subfamily 0, group B, member 2 (Shp/Nr0b2), ferredoxin 1 (Fdx1), scavenger receptor class B, member 1 (Scarb1), inhibin alpha (Inha), and glutathione S-transferase, alpha 3 (Gsta3). We validated the microarray data for a subset of the modulated genes by RT-qPCR. Many of the differentially expressed genes are known to be involved in lipid biosynthesis, lipid metabolism, male gonad development, and steroidogenesis. We identified 262 differentially expressed genes in COUP-TFII-depleted MA-10 cells. To provide new information into the mechanism of action of COUP-TFII in Leydig cells, we performed microarray analyses of COUP-TFII-depleted MA-10 Leydig cells. Until now, only a handful of target genes have been identified for COUP-TFII in Leydig cells. Steroid production has also been shown to be diminished in COUP-TFII-depleted Leydig cells, indicating an important functional role in steroidogenesis. In the testis, COUP-TFII is expressed and plays a role in the differentiation of cells committed to give rise to fully functional steroidogenic adult Leydig cells. Chicken ovalbumin upstream promoter-transcription factors I (COUP-TFI/NR2F1) and COUP-TFII (NR2F2) belong to the steroid/thyroid hormone nuclear receptor superfamily of transcription factors. In males, Leydig cells are the main producers of testosterone and insulin-like 3 (INS元), two hormones essential for sex differentiation and reproductive functions.
