An average sized and weighted Rhesus macaque monkey NOT used in a recent study for a new drug developed by Houston scientists that caused obese monkeys to lose 10 percent of their body weight in a month, sits in its cage at the MD Anderson Cancer Center Keeling Center for Comparative Medicine and Research, Wednesday, Nov. 9, 2011, in Bastrop. Several Rhesus macaque monkeys were selected from the colony of 950 due to their naturally obese bodies and lifestyles, helping provide a perfect test model for human obesity and Type 2 diabetes treatment.
