ABSTRACT
Through several years of exploration in Shanghai Chongming region, the team from Chongming Branch of Xinhua Hospital has established the initial multidisciplinary diagnosis and treatment model of cancer pain, which includes the department of oncology, anesthesiology, pain, rehabilitation, psychology and so forth. By means of medical informationization, they take cancer pain management as the starting point and have initially real-ized a new model of the real-time assessment and treatment of cancer pain, which has helped patients effectively reduce the physical and psychological suffering, improved the quality of life, developed a healthy self-manage-ment of patients, and has reference significance to palliative care.
ABSTRACT
Oncogenic activation of the NF-κB signaling pathway is common in hepatocellular carcinoma (HCC). However, the molecular mechanisms remain largely unexplored. Previous studies have demonstrated that menin, a tumor suppressor protein, could interact with NF-κB protein and repress p65-mediated transcriptional activation. In the present study, we found that expression of menin was frequently down-regulated in HCC tissues and cells. Furthermore, menin could repress p65 acetylation through recruitment of Sirt1, an enzyme that deacetylases p65 in lysine 310 (K310). Indeed, Sirt1 inhibitor or its specific small interfering RNA abolished the inhibitory roles of menin. Together, these observations suggest that the interaction between menin and Sirt1 is required for the tumor suppressor function of menin in HCC.
