Why some people do not respond well to acupuncture-induced analgesia?

A gene called 5’-AMP-activated protein kinase (AMPK), in the hypothalamus of brain is found to determine your responsiveness to acupuncture analgesia, according to a study published in the journal BMC Complementary and Alternative Medicine.

Although acupuncture is now widely used to treat a range of pain conditions, there are some subjects, in many acupuncture analgesia experimental and clinical studies did not respond well, which is difficult to explain.

Researchers in Korea conducted an experimental study to find the factors in the brain determining the sensitivity to acupuncture analgesia in a pain model. Using molecular biotechnologies such as cDNA microarray analysis and reverse transcription polymerase chain reaction, they looked the expression levels of different genes in the hypothalamus, a pain responder region in brain of the subjects. It was found that the levels of gene AMPK was significantly higher in the pain responder subjects than those of non-responder subjects. Further studies showed that inhibition of AMPK expression in the brain attenuated acupuncture-induced analgesic effect in responder subjects.

The studies demonstrated that the levels of AMPK gene expression in the hypothalamus region of brain may determine the individual differences in the sensitivity to acupuncture-induced analgesia.
