Cachectic effect of ciliary neurotrophic factor on innervated skeletal muscle

Abstract

Recombinant human ciliary neurotrophic factor (rh-CNTF) was reported to attenuate skeletal muscle wasting in rats after unilateral transection of the sciatic nerve (M. E. Helgren, S. P. Squinto, H. L. Davis, D. J. Parry, T. G. Bolton, C. S. Heck, Y. Zhu, G. D. Yancopoulos, R. M. Lindsay, and P. S. DiStefano. Cell 76: 493-504, 1994). Under the experimental conditions reported herein, the absolute masses of the denervated gastrocnemius and soleus muscles were not increased in mature or immature rats of either sex by treatment with rhCNTF. At the highest doses of rhCNTF (1 and 0.1 mg/kg), increases in the ratio of the masses of the denervated to the contralateral innervated gastrocnemius and soleus muscles could be attributed entirely to a muscle-wasting effect on the contralateral innervated muscle rather than any muscle-sparing effect on the denervated muscle. The muscle-wasting effects of rhCNTF were associated with reductions in body weight gain and reduced food intake. Pair-fed rats lost less body weight and skeletal muscle mass than rhCNTF-injected freely fed rats but experienced significantly greater loss of visceral mass. Male rats displayed greater loss of body weight and skeletal muscle mass than female rats. Recombinant...Continue Reading

Cachexia & Brown Fat

Cachexia is a condition associated with progressive weight loss due to severe illness. In cancer patients, it is proposed to occur as a result of tumor-induced energy wasting. Several proteins have been implicated in browning and depletion of white adipose tissue. Here is the latest research on cachexia and brown fat.

Anorexia Nervosa

Anorexia nervosa (AN) is a psychiatric condition characterized by severe weight loss and secondary problems associated with malnutrition. Here is the latest research on AN.

Cardiac Cachexia

Cardiac cachexia is a syndrome associated with the progressive loss of muscle and fat mass. It most commonly affects patients with heart failure and can significantly decrease the quality of life and survival in these patients. Here is the latest research on cardiac cachexia.
