Small body size of Sirt6tm2.2Cxd/Sirt6tm2.2Cxd mice

mortality/aging
• most mice die prior to 1 months of age with remaining mice dying within one year
• however, supplementing drinking water with glucose improves survival
• mice exhibit kyphosis, reduced bone density, and increased staining for cellular senescence (increased staining for acidic beta-galactosidase) compared with wild-type mice

reproductive system
• only 6 of 12 female mice produce litters when mated to wild-type males
• male mice cannot impregnate wild-type females unlike wild-type males
• however, sperm is capable of fertilizing eggs normally in vitro

homeostasis/metabolism
• insulin-stimulated glucose uptake in increased in the quadriceps, white adipose tissue, spleen, liver, thymus, and lung compared to in wild-type mice
• throughout nursing
• however, supplementing drinking water with glucose improves circulating glucose levels
• as early as P3

skeleton

growth/size/body
• at P15 and onward
• starting at P3

adipose tissue
• as animals live (visceral and subcutaneous)

vision/eye
• with discharge and not fully open eyes

immune system
• glucose uptake in the spleen is greater than in wild-type mice

behavior/neurological
• mice cannot nurse their young unlike wild-type mice

craniofacial

cellular
• mice exhibit increased staining for acidic beta-galactosidase compared with wild-type mice
