RESUMEN
BACKGROUND: Mammalian or mechanistic target of rapamycin complex 1 (mTORC1) is an effective therapeutic target for diseases such as cancer, diabetes, aging, and neurodegeneration. However, an efficient tool for monitoring mTORC1 inhibition in living cells or tissues is lacking. RESULTS: We developed a genetically encoded mTORC1 sensor called TORSEL. This sensor changes its fluorescence pattern from diffuse to punctate when 4EBP1 dephosphorylation occurs and interacts with eIF4E. TORSEL can specifically sense the physiological, pharmacological, and genetic inhibition of mTORC1 signaling in living cells and tissues. Importantly, TORSEL is a valuable tool for imaging-based visual screening of mTORC1 inhibitors. Using TORSEL, we identified histone deacetylase inhibitors that selectively block nutrient-sensing signaling to inhibit mTORC1. CONCLUSIONS: TORSEL is a unique living cell sensor that efficiently detects the inhibition of mTORC1 activity, and histone deacetylase inhibitors such as panobinostat target mTORC1 signaling through amino acid sensing.
RESUMEN
OBJECTIVE: To probe into the role of electroacupuncture in treatment of peripheral facial paralysis. METHODS: Eighty-six cases were divided into a treatment group (n=45) treated with electroacupuncture plus Chinese medicine, and a control group (n=41) treated with acupuncture plus Chinese medicine. Taiyang (EX-HN 5), Yangbai (GB 14) and other points on the affected side were selected and Chinese medicine modified Qianzheng powder was administrated. Their clinical therapeutic effects were analyzed and evaluated. RESULTS: The effective rate was 97. 8% in the treatment group and 82.9% in the control group with a significant difference between the two groups (P < 0.05). the treatment group being higher than the control group. CONCLUSION: Chinese medicine plus acupuncture combined with electroacupuncture has a better therapeutic effect on peripheral facial paralysis.
