Sugammadex affects GH/GHR’s signaling transduction on muscle cells by regulating the membrane-localized GHR level

Abstract

Objectives Sugammadex (also known as bridion) is a modified γ-cyclodextrin, which is a reversal agent for the neuromuscular block. Growth hormone (GH) has an important biological effect on muscle, regulating muscle growth and development. In the current work, we explored the effect of Sugammadex on GH’s bioactivities. Methods Confocal laser scanning microscope (CLSM), flow cytometry, indirect immunofluorescence, Western-blot, and IP-WB were used to explore the effect of Sugammadex on GH’s bioactivities. Results We found that Sugammadex reduced the activity of GH on muscle cells, which down-regulated GH/GHR-mediated intracellular signaling pathway, such as Janus kinase 2 (JAK2) and signal transducers and activators of transcription 5 (STAT5). We further study the potential biological mechanism by which Sugammadex down-regulated GH/GHR-mediated signaling pathway, a series of related experiments were conducted, and found that Sugammadex may inhibit the proliferation of C2C12 cell via regulating the membrane-localized GHR, which may be the underlying mechanism by which Sugammadex suppressed GHR-induced signaling transduction. This work has laid the theoretical and experimental basis for further exploring the relationship between Sugammadex and GH’s activity. Conclusions In conclusion, this study laid a foundation for further study on the relationship between Sugammadex and GH’s activity.

Personalized Medicine for Classical Anesthesia Drugs and Cancer Progression

“…Sugammadex is considered to enhance recovery after surgery in cancer patients, and a link between its effect on chemotherapy is only documented for breast cancer patients. Sugammadex is related to growth hormone activities [56], also binding to steroid-structure molecules [57], such as estrogen and tamoxifen. Therefore, different agents should be given to patients on tamoxifen to reverse NMB.…”
