Establishment of human neuroblastoma cell-line (SK-N-SH) as an in vitro model of morphine addiction
The usage of morphine for analgesia purposes is widely known, usually for the post-operation procedure and as chronic pain management. However, addiction and overdose liabilities before morphine usage are also common. Morphine addiction is observed and studied from various perspectives; tolerance,...

| Summary: | The usage of morphine for analgesia purposes is widely known, usually for the post-operation procedure and as chronic
pain management. However, addiction and overdose liabilities before morphine usage are also common. Morphine addiction
is observed and studied from various perspectives; tolerance, dependence, and withdrawal. With growing and expending
research field, researches on addiction were done using in vivo and in vitro model. However, the scientific evidence of
morphine addiction using human neuroblastoma cell lines is uncommon. Thus, the present study was designed and conducted
to observe the liability of SK-N-SH, as a model for morphine addiction. The cells were administrated with morphine for 24
hr before being treated with methadone. The cytosolic fraction of the cell was collected and used for determining the addiction
mechanism. Data showed the involvement of the μ-opioid receptor in expressing the addictive properties of morphine.
Exposure to 24 hr morphine had increased the protein level responsible for addiction and reduce the protein levels expressing
the endocytic machinery, desensitization of receptors, and cellular adaptation. The altered proteins level was normalized
by the treatment of methadone. The study proposed the use of SK-N-SH as an addiction model, as it showed morphine
addiction and methadone anti-addiction properties. |
