Skeletal muscle NIK levels decrease after weight loss after gastric bypass surgery in patients with metabolic syndrome. A, Western blottings of six subjects showing overall decline in NIK protein levels after weight loss. Tubulin used as loading control. B, Quantification of NIK pre and post weight loss. *, P < 0.01, pre vs. post weight loss. Pre, presurgery; post, postsurgery. Numerical numbers in the top panel blot indicate different subjects before surgery; a, same patient after surgery.
