    Abnormal messenger ribonucleic acid (mRNA) transcribed from a mutant insulin receptor gene in a patient with type A insulin resistance (1992)

    Notes: Summary In a previous report on a 16-year-old Japanese girl with type A insulin resistance, we found that one allele of the insulin receptor gene was inherited from her mother and contained a 1.2 kilobase pair deletion which removed the 14th exon in the β subunit. We extended investigation of the proband and found the deletion between two Alu sequences. To determine the effect of the deletion on the level of transcription and the splicing pattern of messenger ribonucleic acid (mRNA), we synthesized the complimentary DNA and used the polymerase chain reaction to amplify the region which included the deleted area. The deletion shifted the reading frame, resulting in a termination codon after amino acid 867 (Glu), thereby producing a truncated insulin receptor without a transmembrane region and cytoplasmic domain. We also sequenced each of 22 exons of the insulin receptor gene but found no mutation in exons of the insulin receptor gene, except for deletion of exon 14 of the maternal allele. Thus, the proband is a heterozygote for a single mutant allele. Abnormal mRNA transcribed from the mutant allele resulted in a decrease in insulin binding.

    Defects in insulin binding and receptor kinase in cells from a woman with type A insulin resistance and from her family (1991)

    Notes: Summary Defects in insulin receptor function lead to impairment of the insulin response. We treated a patient with the typical phenotype of type A syndrome of insulin resistance whose insulin receptor seemed to lack the transmembrane region and cytoplasmic domain. Hyperinsulinaemia and resistance to exogenous insulin were evident, and insulin binding to cells and uptake of 2-deoxyglucose into fibroblasts were greatly decreased. Molecular weight of the α-subunit of the insulin receptor was normal, but autophosphorylation and kinase activity were impaired. In the pedigree analysis, defects in insulin binding were also observed in the mother, maternal grandfather and two maternal aunts, corresponding with the abnormality of the insulin receptor gene and mild insulin resistance. In the mother, much the same kinase defects as were seen in the patient became evident. However, no relatives had clinical symptoms similar to those seen in the patient. In the father there was a mild insulin resistance in the glucose clamp study and a borderline impaired glucose tolerance. Although insulin binding to cells was normal in the father, both autophosphorylation and kinase activity were reduced. Our findings suggest that insulin resistance in the patient may be caused by the defects in insulin receptor kinase activity as well as by a reduction in insulin binding activity.

    Surface chlorination of polypropylene film by CHCI3 plasma (1994)

    Notes: Polypropylene films were treated with the CHCI3 plasma, and their chemical composition was analyzed with XPS and ART IR spectroscopy. The CHCI3 plasma irradiation made polypropylene films hydrophilic. The advancing contact angle decreases from 95° for the untreated to about 73° for the CHCI3 plasma-treated films. In the CHCI3 plasma irradiation, the chlorination occurs, and C—Cl, C—Cl2, and C—Cl3 units are formed in the polypropylene films. Simultaneously with the chlorination, unsaturated units (C=C and conjugated C=C units) are formed from dehydrogen chlorination of the chlorinated products, but the oxygen incorporation into the films is low. The CHCI3 plasma is preferred in chlorination of polypropylene films to the CCl4 plasma. © 1994 John Wiley & Sons, Inc.

    Notes: X-ray photoelectron spectroscopy (XPS) of Ne ion-bombarded polymer has been carried out in order to examine the cause of HeLa cell adhesion control on polymers. Substrates used were polystyrene (PS) and oxygen plasma-treated polystyrene (PS-O). Neon bombardments into the patterned region of PS and PS-O were performed at an energy of 150 keV with fluences of 1×1014 and 1×1015 ions cm-2. The surface chemical bonding states were investigated by XPS. In HeLa cell adhesion measurements, the Ne-bombarded region of PS with a fluence of 1×1015 ions cm-2 exhibits higher adhesion and spreading of HeLa cells than the unbombarded region. On the contrary, it is found that the Ne-bombarded region of PS-O inhibits HeLa cell adhesion. The XPS results show that Ne bombardment to PS or PS-O destroys the original chemical bonds and consequently produces new functional groups. It is considered that the drastic change of surface chemical bonding states from the pristine states induced by Ne bombardment leads to a clear distinction between increasing and inhibiting HeLa cell adhesion.

    Quantitative analysis by XPS using the multiline approach (1994)

    Notes: An efficient method for quantitative XPS analysis is the so-called multiline approach. This method does not require standards, it takes into account the instrumental and matrix effects and it derives quantitative information from statistical analysis of all photoelectron intensities visible in the spectra. One can expect the reliability of this approach to be better than the reliability of methods involving uncorrected relative sensitivity factors. This paper summarizes recent improvements in the multiline approach. In particular, a new expression for the universal energy dependence of the inelastic mean free path is currently used. Furthermore, the statistical analysis has been modified in order to account properly for the error in the countrates. Finally, a database with physical constants has been added (photoionization cross-sections, asymmetry parameters, binding energies, etc.) to avoid errors of polynomial approximations. The modified algorithm of the multiline approach was applied to photoelectron intensities measured for AuCu alloys in four laboratories. Surfaces of these alloys were sputtered with 2 keV Ar+ ions, because at this energy the selective sputtering effects are expected to be negliible. Very consistent results were obtained. The average deviation from the bulk surface composition was found to be equal to ±3.2 at.%. Extensive software implementing the described version of the multiline approach is presently being developed.
