Users’ Emotional Attachments to Internet Celebrities: Based on the Perspective of Extended-self

Although previous researcher has focused on the use of social media between celebrities and fans from the use and gratification perspective, knowledge on why users stick with live streaming is limited. Therefore, the authors propose that sticking with live streaming reflects a strong connection between celebrities and users. We define emotional attachment as the strength of the cognitive and emotional bond connecting the celebrities with the self. Consequently, in this study, we adopt attachment theory to investigate users’ tendency to stick with live streaming from the extended-self perspective. The findings of this study fully support the hypotheses specifying the relationships between constructs. Emotional attachment was influenced by gratifying the self, enriching the self and enabling the self, and which in turn are strong predictors of users’ stickiness intention. The current research contributes to the further expansion of social media research and applied attachment theory into the live streaming context

Datasets of YY1 expression in rheumatoid arthritis patients

The data presented in this article are related to the research article entitled “A critical role of transcription factor YY1 in rheumatoid arthritis by regulation of interleukin-6” (J. Lin, Y. He, J. Chen, Z. Zeng, B. Yang, Q. Ou, 2016) [1]. The article describes YY1 overexpression is specific for RA, but not for SLE, SS, DM or MCTD. In early RA, YY1 expression is also increased. In asymptomatic subjects with RF or ACPA positive who have high risk for developing RA, the YY1 expression is not increased obviously. Moreover, YY1 expression is positively correlated with serum CRP or ESR. In RA patients treated with anti-IL-6R monoclonal Ab tocilizumab, there is no significant difference in YY1 expression after IL-6 blocking therapy

Identification of Neuronal RNA Targets of TDP-43-containing Ribonucleoprotein Complexes*♦

TAR DNA-binding protein 43 (TDP-43) is associated with a spectrum of neurodegenerative diseases. Although TDP-43 resembles heterogeneous nuclear ribonucleoproteins, its RNA targets and physiological protein partners remain unknown. Here we identify RNA targets of TDP-43 from cortical neurons by RNA immunoprecipitation followed by deep sequencing (RIP-seq). The canonical TDP-43 binding site (TG)n is 55.1-fold enriched, and moreover, a variant with adenine in the middle, (TG)nTA(TG)m, is highly abundant among reads in our TDP-43 RIP-seq library. TDP-43 RNA targets can be divided into three different groups: those primarily binding in introns, in exons, and across both introns and exons. TDP-43 RNA targets are particularly enriched for Gene Ontology terms related to synaptic function, RNA metabolism, and neuronal development. Furthermore, TDP-43 binds to a number of RNAs encoding for proteins implicated in neurodegeneration, including TDP-43 itself, FUS/TLS, progranulin, Tau, and ataxin 1 and -2. We also identify 25 proteins that co-purify with TDP-43 from rodent brain nuclear extracts. Prominent among them are nuclear proteins involved in pre-mRNA splicing and RNA stability and transport. Also notable are two neuron-enriched proteins, methyl CpG-binding protein 2 and polypyrimidine tract-binding protein 2 (PTBP2). A PTBP2 consensus RNA binding motif is enriched in the TDP-43 RIP-seq library, suggesting that PTBP2 may co-regulate TDP-43 RNA targets. This work thus reveals the protein and RNA components of the TDP-43-containing ribonucleoprotein complexes and provides a framework for understanding how dysregulation of TDP-43 in RNA metabolism contributes to neurodegeneration
