Elevated urinary ADAM12 protein levels in lithium-treated bipolar patients.
ADAM (A Disintegrin And Metalloprotease)12 is a member of a family of integral membrane and secreted glycoproteins. ADAM12 has recently been detected in urine. In the present study we measured ADAM12 protein levels in urine from bipolar patients vs. healthy controls. Nineteen bipolar patients and 22 matched-control subjects were studied. Urine samples were concentrated and Western-blot analysis used to determine ADAM12 protein levels. The 92 kDa form of urine ADAM12 protein levels were highly elevated in Li-treated bipolar patients compared with normal controls. The 68 kDa form of urine ADAM12 protein levels did not differ. Future experiments are needed to explore a potential link between ADAM12 protein level elevation and lithium response.
