Overexpressed full-length (FL) CREBRF protein was stabilized by MG132; however, the intrinsic CREBRF expression in Neuro2a cells was negligible under all conditions. On the other hand, N- or C-terminal deletion of CREBRF influenced its stability. Cotransfection of CREBRF together with GAL4-tagged FL CREB3 increased luciferase reporter activity, and only the N-terminal region of CREBRF was sufficient to potentiate luciferase activity. Furthermore, this positive effect of CREBRF was also observed in cells expressing GAL4-tagged cleaved CREB3, although CREBRF hardly influenced the protein stability of NanoLuc-tagged cleaved CREB3 or intracellular localization of EGFP-tagged one. In conclusion, this study suggests that CREBRF, a quite unstable proteasome substrate, positively regulates the CREB3 pathway, which is distinct from the canonical ER stress pathway in Neuro2a cells. Quality of life (QoL) has been the subject of increasing interest in oncology. Most examinations of QoL have focused on health-related QoL, while other factors often remain unconsidered. Moreover, QoL questionnaires implicitly assume that the subjective importance of the various QoL domains is identical from one patient to the next. The aim of this study was to analyze QoL in a broader sense, considering the subjective importance of the QoL components. A sample of 173 male urologic patients was surveyed twice once while hospitalized (t1) and once again 3 months later (t2). Patients completed the Questions on Life Satisfaction questionnaire (FLZ-M), which includes satisfaction and importance ratings for eight dimensions of QoL. A control group was taken from the general population (n = 477). Health was the most important QoL dimension for both the patient and the general population groups. While satisf
