Muscle Signaling and Estrogen:
The MUSE Study

The MUSE study will examine the effects of the female sex hormone estrogen on changes in muscle due to lack of use. The goal of this research study is to find out if estrogen helps protect against muscle loss when the muscle is used very little.

Women in the MUSE study will be asked to wear a knee brace on the left leg for 9 days to immobilize the leg. Women will also receive daily injections of a hormone-suppressing drug for 13 days. This drug will cause blood sex hormone levels to decrease to postmenopausal levels. At the same time, participants will be randomly assigned to wear either an estrogen or a placebo (inactive substance) skin patch for 13 days. Neither the women in the study nor the study team will know if the patch is estrogen or placebo. Three muscle biopsies will be performed; one prior to immobilization, one directly following immobilization, and one 4 days after the immobilization period. This will allow us to determine the effect that estrogen has on muscle tissue following a period of disuse.

Qualifications to volunteer:

  • Healthy women between the age of 21-40 years
  • Regular menstrual cycles
  • No current use of hormonal contraceptives
  • Physically active but not a competitive athlete
  • Willing to wear a knee brace and use crutches for 9 days

Benefits for study volunteers include:

  • Measurement of body composition and bone density
  • Fitness testing
  • Compensation will be provided for your time

The Principal Investigator for the MUSE study is Catherine Jankowski, PhD. For more information please contact Ellie Gibbons at 720-848-6408 or Ellie.Gibbons@ucdenver.edu. This study is funded by the UCD Department of Medicine and has been approved by the Colorado Multiple Institutional Review Board. (COMIRB #07-0379)

A Familiar IMAGE Face

Many of you will remember the winning smile and quick wit of Angie Moquin, the very first IMAGE professional research assistant. Angie was deeply involved with the AFTER and BONE studies and supervised exercise as recently as a year ago while working on her doctorate of physical therapy degree. We are proud to announce that Angie graduated from the University of Colorado Physical Therapy Program in May, 2009, and is now Dr. Angie (Angela) Moquin, MS, PT, DPT. She will begin working as a physical therapist in Nevada later this summer. Angie has a special interest in helping people with artificial limbs to not only rehabilitate but also to accomplish personal performance goals. Kudos to Angie!

Ever wonder why women gain abdominal fat after menopause? Is your body changing without your consent? If so, then keep reading to learn more about the SCALE study!


Abdominal fat is associated with increased risk for heart disease and adult onset diabetes. Cortisol, a stress hormone, is known to increase abdominal fat. The rate of fat gain in women, especially in the abdominal area, increases after menopause. Why this occurs is not known. One possibility is that the loss of estrogen at menopause may increase abdominal fat by changing cortisol metabolism.

SCALE is a research study that will determine the separate effects of estrogen and weight loss on the stress hormone cortisol. The findings from this study may lead to the development of ways to help decrease abdominal fat gain after menopause.

Eligible participants are healthy, nonsmoking, sedentary, postmenopausal women aged 40-59 who do not currently take hormone therapy, are willing to wear an estrogen or placebo patch for 1 month, and are able to take part in a 4 month supervised aerobic exercise program designed to reduce body weight by at least 5%.

Wendolyn S. Gozansky, MD, MPH is the Principal Investigator for SCALE (COMIRB #07-0278). For more information about this study funded by the National Institutes of Health, please contact Kathryn Cardwell at 720-848-6418 or .







Our type of research would not be possible without the dedication of our research volunteers. We sincerely thank you for giving us your commitment, time, and energy.

DOES THE IMAGE GROUP HAVE A STUDY FOR YOU?

Studies for Women & Men:

  • The MOXI Study is examining how the use of ibuprofen in older, exercising women and men affects muscle and bone health. Eligible participants are 60-75 years of age who are not currently in a weight lifting program, have no history of peptic ulcers or stomach bleeding, and do not typically use acetaminophen, ibuprofen, or similar drugs more than 3 days per month. (COMIRB #06-0769)
  • The POEM Study is examining whether 6 months of cardiovascular exercise training or a study drug (Pioglitazone) can improve memory function. Eligible participants are healthy adults over the age of 55 years who are experiencing mild memory problems, are slightly overweight and considered pre-diabetic, non-smokers, and not regularly exercising. (COMIRB # 07-1215)
  • The Lose-It Study will investigate the amount of exercise that health care providers should prescribe in order for patients to maintain weight loss. Eligible participants are healthy men and women between 18-45 years of age. Participants must be willing to engage in lifestyle changes including diet modifications and up to 100 minutes of daily physical activity. (COMIRB # 06-0369)
  • The Minimally Invasive Total Knee Replacement Study looks at different surgical approaches for total knee replacement and combines these with a progressive rehabilitation program. Eligible adults are 50 to 85 years of age and are candidates for knee replacement surgery with Dr. Michael Dayton at the University of Colorado Hospital. (COMIRB #06-0183)
  • The Rehabilitation for Total Knee Replacement Study is investigating 2 rehabilitation programs designed to restore muscle strength more effectively to improve function with daily activities. Eligible adults are 50 to 85 years of age and are candidates for knee replacement surgery. (COMIRB #06-0074)
Studies for Women:

  • The HRTEX Study is examining the effects of various types of hormone replacement therapies along with a walking exercise program on women’s health.  Eligible participants are postmenopausal healthy, sedentary women between the ages of 45-65 years of age and are not currently taking hormone replacement therapy. (COMIRB #05-0606)
  • The POWER Study is examining the role of the female sex hormone estrogen in preventing excess fat gain in women. Eligible participants are healthy women aged 20-40, who have regular menstrual cycles, and are not currently using hormonal contraceptives. (COMIRB #06-0512)
