RESUMO
As a member of the sirtuins family, also called Class III histone deacetylases (HDACs), SIRT6 has many catalytic enzyme activities and plays a pivotal role in biological processes including anti-aging, chromatin regulation, transcriptional control, glucose and lipid metabolism, and DNA damage repair. Recently, increasing evidences indicated that SIRT6 was related to initiation and development of tumors, such as hepatic cancer, lung cancer, breast cancer and genital system tumors. However, SIRT6 might play a dual role in tumorigenesis and progression. SIRT6 often acted as a tumor suppressor, but might play an oncogenic role. Based on our current study, we depicted the essential roles of SIRT6 in the initiation and progression of various tumors, and summarized its mode of actions, which might provide clues for cancer therapy.

Objective To investigate the effect of decoction of Fructus Gardeniae in decreasing blood sugar level in normal mice and diabetes mellitus mice (DM). Methods DM mice models were induced by glucose, adrenalin, desamethasone and alloxan respectively. After treatment, the influence of Fructus Gardeniae on blood sugar level in normal mice and DM mice was observed. Results Fructus Gardeniae decreased the blood sugar level significantly in DM mice and slightly in normal mice. Conclusion Fructus Gardeniae is effective in decreasing blood sugar level in both normal mice and several DM mice.
