Former studies demonstrated that the cembranoid type diterpenes in tobacco has a good antimicrobial, antitumor and neuroprotective activity. Hepatocellular carcinoma has been the world's second largest malignant tumor in recent years. In this study, we isolated cembranoid type diterpenes from tobancco and detected its antitumor activity on hepatoma cell lines, a-2, 7, 11-cyprotermine-4, 6-diol (a-CBD) was used to investigate its antitumor activity on HepG2 cells in vitro.

View SamplesAlteration in gene expression accompanying initial stages of allopolyploidy is a prominent feature in plants, but its spectrum and model are highly idiosyncratic. We used multi-colour GISH to identify individuals from two nascent allohexaploid wheat lines between Triticum turgidum and Aegilops tauschii, which had a transgenerationally stable chromosomal constitution mimicking that of common wheat. We performed genomewide analysis of gene expression for these plants along with their parental species using the Affymetrix GeneChip Wheat Genome-Array. Comparison with parental species coupled with inclusion of empirical mid-parent values (MPVs) revealed two patterns of alteration in gene expression in the allohexaploid lines: parental dominance expression and nonadditive expression. Genes involved in each altered pattern could be classified into three distinct groups, stochastic, heritable and persistent, based on their transgenerational heritability and inter-line conservation. Whereas both altered patterns of gene expression showed a propensity of inheritance, identity of the involved genes is stochastic, consistent with the involvement of diverse Gene Ontology (GO) terms. Nonetheless, those genes showing nonadditive expression exhibited a significant enrichment for vesicle-function. Our results suggest global alteration in gene expression conditioned by nascent allopolyploidy likely play functional roles in stabilization and establishment of the newly formed plants, and consequential to evolution.

View SamplesHaploid pluripotent stem cells, such as haploid embryonic stem cells (haESCs), facilitate the genetic study of recessive traits. In vitro, fish haESCs maintain haploidy in both undifferentiated and differentiated states, but whether mammalian haESCs can preserve pluripotency in the haploid state has not been tested. Here, we report that mouse haESCs can differentiate in vitro into haploid epiblast stem cells (haEpiSCs), which maintain an intact haploid genome, unlimited self-renewal potential, and durable pluripotency to differentiate into various tissues in vitro and in vivo. Mechanistically, the maintenance of self-renewal potential depends on the Activin/bFGF pathway. We further show that haEpiSCs can differentiate in vitro into haploid progenitor-like cells.

View SamplesIn plants, CCCH zinc finger proteins involved in secondary wall formation and anther development are poorly understood. We have functionally identified two homologous genes C3H14 and C3H15 and found that the two genes differentially regulate secondary wall formation and anther development. C3H14 contributes more to secondary wall thickening, whereas, C3H15 is more important for anther development.
Arabidopsis C3H14 and C3H15 have overlapping roles in the regulation of secondary wall thickening and anther development.
