ABSTRACT
Childhood acute lymphoblastic leukemia (C-ALL) is the most common pediatric cancer. Although its etiology remains poorly understood, the hypothesis of ALL correlated with a genetic basis was examined through association studies based on candidate genes. Recently, two independent large-scale genome-wide association studies reported that the five single nucleotide polymorphisms (rs7073837; rs10821936; rs10994982; rs7089424; rs10740055) in the gene AT rich interactive domain 5B (ARID5B) at 10q21.2, were associated with the high incidence risk of C-ALL, especially with hyperdiploid lymphoblastic leukemia. Variations in these single nucleotide polymorphisms influence the risk of specific disease subtypes, and also possess race- and sex-differences in leukemia incidence. Further elucidation of the mechanisms through which ARID5B variants are involved in C-ALL not only has a great diagnostic value, but also a guidance for the clinical therapy, ultimately improving the prognosis of disease. Therefore, the related studies of ARID5B with C-ALL were summarized briefly in this review.

Qualitative and quantitative differences in proteins expressed in the middle silkglands of male and female silkworm larvae that differ in silk colour were investigated by high resolution two-dimensional polyacrylamide gel electrophoresis (2-D PAGE), followed by computer assisted image analysis. About 1000 protein spots were resolved in both the sexes and most proteins were shown to be distributed in the area from 15 kDa to 70 kDa and pH 4-8. It was found that some proteins displayed higher expression in yellow cocoon, while two proteins were only expressed in female silkworm silkgland tissue through the comparison and analysis by two-D software. These proteins especially existed in female silkworm middle silkgland tissue of yellow cocoon. Furthermore, these proteins might be involved in the expression of cocoon colour phenotype
