Objectives: Long non-coding RNAs (lncRNAs), a vast class of recently discovered non-coding genes in the human genome, have been implicated in the regulation of several biological processes, including the maintenance of stem cell pluripotency and neurogenesis. New evidences have emerged that some long IncRNAs act as enhancers for their neighboring genes. Oct4, also known as POU5F1 and Oct3/4, functions as a master regulator in maintaining the properties of pluripotency and self-renewal of embryonic stem (ES) cells and embryonal carcinoma (EC) cells. Oct-4 expression must be tightly regulated; too much or too little expression can lead to cell differentiation. Methods: PSORS1C3, an IncRNA, is located upstream of the Oct4 gene. This IncRNA could potentially impact the level of Oct4 expression. Here, we have investigated potential expression of PSORS1C3 on 23 different human pluripotent and cancer cell lines by means of RT-PCR. Results: Our results revealed a noticeable expression of PSORS1C3 both in a well-known pluripotent cell line (NTera2/NT2) and five different cancer cell lines (AGS, 5637, Ht-29, HepG2 and PC3). Conclusion: We detected the expression of PSORS1C3 for the first time in both cancer cell lines and stem cells.

The global development of social media and the acceptance of luxury products among Iranian customers have significant effects on the marketing activities of luxury brands and their customer equity. The objective of this research is to examine the effect of Social Media Marketing(SMM) activities on customer equity of luxury brands. In terms of objective, this research was descriptive of survey type. The statistical population of the present research was Dorsa’s customers with a sample size of 384. In order to test the hypotheses, Structural Equation Modeling (SEM) and AMOS software were used. The results showed that SMM activities have positive impacts on value equity, relationship equity, brand equity, and attitudinal equity. Moreover, relationship equity and brand equity have positive impacts on customer equity, and purchase intention is directly affected by value equity and relationship equity. Eventually, purchase intention and brand experience had a positive effect on customer equity.
