The effects of calpain inhibitors on the total number of acetylcholine receptors (AChRs) on cultured rat myotubes and on the stability of AChR clusters in these myotubes were investigated. The degradation rate of total AChRs labeled with 125 I-␣-bungarotoxin was assessed from radioactivity remaining

✦ Synopsis
Interferon enhances alpha-bungarotoxin binding on 5-day-old rat myotubes. The increase is time- and dose-dependent. KD for alpha-bungarotoxin remains unchanged in the presence and in the absence of interferon, while the maximum number of binding sites is dramatically affected by interferon. Cycloheximide inhibits the effect of interferon, which suggests that the enhancement of alpha-bungarotoxin binding depends on protein synthesis.

Aldose reductase (AR) is known to be responsible for many side effects of diabetes. In the present work, we studied the effects of various extracellular signals on the regulation of the expression of AR in astrocytes in culture, by determining its enzymatic activity or its mRNA level. We found that
The properties of the Na-K pump and some of the factors controlling its amount and function were studied in rat myotubes in culture. The number of Na-K pump sites was quantified by measuring the amount of [3H]ouabain bound to whole-cell preparations. Activity of the pump was determined by measuremen
Somatostatin is one of the numerous peptides described in the Harderian gland of different animals. With the aim of trying to elucidate its physiological role, we investigated whether this peptide is expressed in OFA rat Harderian gland at different ages and seasons and, if so, studied the regulator
