A novel hydroxyproline-rich glycoprotein (SbHRGP3) that consists of two different domains is encoded by an extensin gene from soybean. The first domain (domain 1) located at the N terminus is composed of 11 repeats of Ser-Pro4-Lys-His-Ser-Pro4-Tyr3-His, whereas the second domain (domain 2) at the C terminus contains five repeats of Ser-Pro4-Val-Tyr-Lys-Tyr-Lys-Ser-Pro4-Tyr-Lys-Tyr-Pro-Ser-Pro5-Tyr-Lys-T yr- Pro-Ser-Pro4-Val-Tyr-Lys-Tyr-Lys. These two repeat motifs are organized in an extremely well-ordered pattern in each domain, which suggests that SbHRGP3 belongs to a new group of proteins having the repeat motifs of two distinct groups of dicot extensins. The expression of the SbHRGP3 gene increased with seedling maturation, and its expression was relatively high in the mature regions of the hypocotyl and in the root of soybean seedlings. An SbHRGP3-beta-glucuronidase (SbHRGP3-GUS) chimeric gene was constructed and expressed in transgenic tobacco plants. The expression of the SbHRGP3-GUS gene was not induced by wounding alone in transgenic tobacco plants; sucrose was also required. Expression was specific to phloem tissues and cambium cells of leaves and stems. In transgenic tobacco seedlings, SbHRGP3-GUS gene expression was activated by the maturation of the primary root and then inactivated; however, reactivation was specifically at the epidermis of the zone from which the lateral root was to be initiated. Its reactivation occurred just before the lateral root initiation. These results indicate that the SbHRGP3 gene in different tissues responds to different signals.

The Association between Impaired FastingGlucose and Noise-induced Hearing Loss: Tae-Won Jang, et al. Department of Occupational and Environmental Medicine, Hangang Sacred Heart Hospital, Hallym University College of Medicine, Korea-Objectives: This study was performed to determine whether there is an association between impaired fasting glucose and noise-induced hearing loss. Methods: The study subjects were workers in one automobile manufacturing company. The data were obtained from results of health examinations during 2005 and 2009. The factors analyzed were age, smoking and alcohol history, work duration, environmental noise level, hearing thresholds, blood pressure, serum creatinine, initial hearing threshold and fasting glucose. Results:The hearing thresholds at 4,000 Hz frequencies for both ears were significantly higher in 2009 than those in 2005. The changes in the hearing thresholds of the subjects with an impaired fasting glucose (100-125 mg/dl) and diabetes (≥126 mg/dl) were greater than those of the normal (<100 mg/dl) group. After adjusting for variables such as age, smoking and alcohol history, environmental noise, hypertension and serum creatinine, fasting glucose was found to be a significant variable. Impaired fasting glucose (100-125 mg/dl) was significant (β=1.339, p=0.002) for the right ear, whereas it was not significant (β=0.639, p=0.121) for the left ear. Conclusions: Impaired fasting glucose, as well as diabetes, might be risk factors for hearing loss in individuals with exposure to certain noise levels. The results of this study suggest that impaired fasting glucose should be considered a risk factor for hearing loss. (J Occup Health 2011; 53: 274-279)
