- Four superdeformed bands extending over five to twelve transitions have been identified in Sr-81 from a study With the Gammasphere array and the Microball charged-particle array, One of the bands shows an upbend in the dynamic moment of inertia at a rotational frequency of 1.2 MeV and all bands exhibit a nearly constant moment of inertia below that frequency.

- The insulin-like growth factor-I receptor (IGF-IR) is involved in tumorigenesis. The aim of the present study was to investigate whether the IGF-IR is a physiological target for p53 in osteosarcoma cells. The p53-induced regulation of IGF-IR levels was studied in a tetracycline-regulated expression system. When expressed in Saos-2, osteosarcoma cells that lack p53, wild-type p53 decreased, whereas mutated p53 increased IGF-IR expression, and IGF-I-induced tyrosine phosphorylation of the IGF-IR. Similarly, wild-type p53 decreased IGF-I-induced tyrosine phosphorylation of IRS-1. A functional and physical interaction between p53 and Sp1, in the regulation of the IGF-R, was studied in osteosarcoma cells. Expression of p53 decreased IGF-IR promoter activity, whereas no effect on promoter activity was seen by Sp1 expressed alone. However, Sp1 counteracted the inhibitory effect of p53 on IGF-IR promoter activity in a dose-dependent manner. Furthermore, wild-type and mutated p53 were coimmunoprecipitated with Sp1, indicating a physical interaction between p53 and Sp1. In conclusion, p53 regulates IGF-IR expression, as reflected by a reduction in IGF-IR protein and a parallel reduction in IGF-I-induced tyrosine phosphorylation of the IGF-IR and IRS-1 in an osteosarcoma cell line. These data indicate that the IGF-I receptor is a physiological target for p53 in osteosarcoma cells. Furthermore, data supporting an interaction between p53 and Sp1 in the regulation of the promoter activity of IGF-IR are presented.
