ZNF322A encoding a classical Cys2His2 zinc finger transcription factor was previously revealed as a potential oncogene in lung cancer patients. However, the oncogenic role of ZNF322A and its underlying mechanism in lung tumorigenesis remain elusive. Here we show ZNF322A protein overexpression in 123 Asian and 74 Caucasian lung cancer patients. Multivariate Cox regression analysis indicated that ZNF322A was an independent risk factor for a poor outcome in lung cancer, corroborating the Kaplan–Meier results that patients with ZNF322A protein overexpression had significantly poorer overall survival than other patients. Overexpression of ZNF322A promoted cell proliferation and soft agar growth by prolonging cell cycle in S phase in multiple lung cell lines, including the immortalized lung cell BEAS-2B. In addition, ZNF322A overexpression enhanced cell migration and invasion, whereas knockdown of ZNF322A reduced cell growth, invasion and metastasis abilities in vitro and in vivo. Quantitative proteomic analysis revealed potential ZNF322A-regulated downstream targets, including alpha-adducin (ADD1), cyclin D1 (CCND1), and p53. Using luciferase promoter activity assay combined with site-directed mutagenesis and sequential chromatin immunoprecipitation-PCR assay, we found that ZNF322A could form a complex with c-Jun and cooperatively activate ADD1 and CCND1 but repress p53 gene transcription by recruiting differential chromatin modifiers, such as histone deacetylase 3, in an AP-1 element dependent manner. Reconstitution experiments indicated that CCND1 and p53 were important to ZNF322A-mediated promotion of cell proliferation, whereas ADD1 was necessary for ZNF322A-mediated cell migration and invasion. Our results provide compelling evidence that ZNF322A overexpression transcriptionally dysregulates genes involved in cell growth and motility therefore contributes to lung tumorigenesis and poor prognosis.

Purpose To determine the prevalence of selfreported myopia nationwide in Taiwan and its association with degrees of urbanization and education levels. Methods Data were obtained from the 2005 Taiwan National Health Interview Survey, a nationwide survey using multistage stratified systematic sampling. The presence of myopia, current residential areas, and education levels were ascertained by a structured questionnaire in participants Z12 years of age. Results A total of 20 609 eligible persons were included in this study. The overall weighted prevalence of myopia in Taiwan was 46.7% (95% confidence interval: 45.9, 47.5%). The prevalence of myopia for persons aged 12-19, 20-39, 40-64, and Z65 years was 70.3%, 65.4%, 30.4%, and 5.6%, respectively. Women had significantly higher rates of myopia than men for persons younger than 40 years of age (Po0.001). Myopia was significantly associated with both higher degrees of urbanization of current residential areas and higher education levels (both Po0.001). In young adult and adult groups, the effect of education levels on myopia was stronger than that of degrees of urbanization. Conclusion The study provides a nationwide prevalence data on myopia in Taiwan. Both degrees of urbanization and education levels are risk factors for myopia.

A new species, Macromotettixoides lativertex Deng et al n. sp. is described with detailed illustrations of external morphology. Comparison between the species M. lativertex n. sp. and allied species is compiled into a table for identification. The distribution and an updated identification key to all known species of the genus is given.

Abstract. From 2 senior‐high and 2 vocational schools in Taipei, 3251 children with age 16–19 were randomly selected to study the relationship between ocular refraction and its main optical components, corneal curvature and axial length. While the corneal curvature was found to play only a minor role in the determination of ocular refraction, the measurements of axial length parallelled the degree of myopia (r = 0.74). A two‐years' longitudinal study of additional 411 children from one junior‐high school (age 13 through 15) further pointed to the importance of axial length in the production and progression of myopia.
