Progress in molecular biology of a semi-mangrove, Millettia pinnata / 生物工程学报

Millettia pinnata L. is a leguminous tree with great potential in biodiesel applications and also a typical semi-mangrove. In this review, we presented several aspects about the recent research progress in molecular biology of M. pinnata. We descrived several types of molecular markers used to assess the genetic diversity and phylogeny of this species, genome and transcriptome analyses based on high-throughput sequencing platform accomplished for this species, and several gene and genomic sequences of this species isolated for further research. Finally, based on the current research progress, we proposed some orientations for future molecular biology research on M. pinnata.

Functions of late embryogenesis abundant proteins in desiccation-tolerance of organisms: a review / 生物工程学报

Late embryogenesis abundant (LEA) proteins are well associated with the desiccation tolerance in organisms. LEA proteins are categorized into at least seven groups by virtue of similarities in their deduced amino acid sequences. Most of the LEA proteins have the characteristics of high hydrophilicity and thermo-stability. The LEA proteins are in unstructured conformation in aqueous solution. However, they adopted amphiphilic alpha-helix structure during desiccation condition. LEA proteins are localized to the different organelles in the cells, i.e. cytoplasm, endoplasmic reticulum, mitochondria and nucleus. The multi-functional capacity of LEA proteins are suggested, as protein stabilization, protection of enzyme activity, membrane association and stabilization, antioxidant function, metal-ion binding or DNA protection, etc. Here, we review the structural and functional characteristics of LEA proteins to provide a reference platform to understand their protective mechanisms during the adaptive response to desiccation in organisms.

Regulation of Recipe Xiaoban No.1 on expression of P53 in dystrophy of vulva / 中华中医药杂志

Objective:To explore the regulation of Recipe Xiaoban No.1 on the expression of p53 in dystrophy of vulva.Methods:Expression of p53 was determined by immunohistochemical technique in skin lesion of prior treatment and posttreatment from 30 cases with chronic vulvar dystrophy,and normal skin from 23 health adults were served as controls.Results: Expression of p53 in various of chronic dystrophy of vulva before treatment was obviously higher than control group(P0.05).Conclusion:Recipe Xiaoban No.1 can obviously improve the clinical symptoms and decrease the expression rate of P53.
