WitrynaHigh FIRRE levels are closely associated with poor OS. 37 Another lncRNA, nuclear paraspeckle assembly transcript 1_1 (NEAT1_1), which usually functions as an oncogene in human malignancies, is highly expressed in DLBCL patients and might serve as a predictive marker of poor prognosis. 38 Tang et al found that increased … WitrynaThus, one explanation of the Paraspeckle's function is that it provides ordered localisation of its component proteins and to thereby help direct their activity. In turn, this is believed to give the Paraspeckle a regulatory function over transcription. [10] punch atriocThe role of the Paraspeckle is as of yet not fully understood. It has been suggested that the activity of NONO (a.k.a. p54nrb), a protein component, is dependent on its localisation within the nucleus. Thus, one explanation of the Paraspeckle's function is that it provides ordered localisation of its component proteins and to thereby help direct their activity. In turn, this is believed to give the Paraspeckle a regulatory function over transcription. Also, a meta-analysis b… punch at party
