Research has demonstrated that a wide variety of environmental conditions are capable of producing analgesia. In the present experiment, the analgesia produced by 24 hr of food deprivation was examined following adrenalectomy, hypophysectomy, naltrexone (7 mg/kg), dexamethasone (0.4 mg/kg), or saline treatment. Results revealed that 24 hr of starvation(More)
The gene encoding calcitonin gene-related peptide (CGRP) is inducible by nerve growth factor (NGF) in primary dorsal root ganglion neurons. By transfecting these primary neurons, we have defined a region of the CGRP promoter from -140 to -72 relative to the transcriptional start site which is essential for its inducibility by NGF as well as by cyclic AMP(More)
In order to study the age-related differences in analgesia produced by environmental stimuli, 3-month-old, 11-month-old, and 23-month-old rats were immersed in 6 degrees C water for 5 min. Prior to cold-water exposure, different groups of rats were injected (i.p.) with 7 mg/kg of naltrexone or saline or had adrenalectomies performed. Following cold-water(More)
The calcitonin/CGRP gene is transcribed in thyroid C cells and some neuronal cells but not in other cell types. Although the promoter sequences mediating gene activity in thyroid C cells have been extensively studied, the elements responsible for promoter activity in neuronal cells and its stimulation by nerve growth factor (NGF) have not previously been(More)
Collagen fibrils become resistant to cleavage over time. We hypothesized that resistance to type I collagen proteolysis not only marks biological aging but also drives it. To test this, we followed mice with a targeted mutation (Col1a1(r/r) ) that yields collagenase-resistant type I collagen. Compared with wild-type littermates, Col1a1(r/r) mice had a(More)
Intense, generalized pruritus associated with mycosis fungoides was relieved using subcutaneous naloxone but intensified when changed to the new oral opioid antagonist, naltrexone. Rechallenge again led to worsening in pruritus. This unexpected adverse effect is surprising as naltrexone and naloxone are currently thought to work via similar opioid receptor(More)
