LEPR and obesity due to melanocortin 4 receptor deficiency: For some obesity rodent models, we found no example of acupuncture studies: this is the case for SHRSP/IDmcr-fas rats [71], db/db mice (loss of function mutation in the gene encoding leptin receptor) [78, 116], KK/HlJ mice [76], high-fat diet induced obesity Swiss mice [64], and C57BL/6NCrl mice [65].
