Compared with numerous studies of somatic mutations using sporadic lung cancer, the research into germline mutations using familial lung cancer (FLC) is limited. In the present study, we used FLC samples obtained from the Chinese population in highly air-polluted regions to screen for novel germline mutations in lung cancer. Through a whole genome sequencing (WGS) analysis of the nine subjects (four...
Taxus spp. are ancient gymnosperms that produce a unique secondary metabolite, namely, taxol, an anticancer drug. JAZ proteins are key regulators of the JA signaling pathway, which control taxol biosynthesis. However, the JAZ proteins of Taxus spp. are poorly studied. In this work, nine JAZ genes from Taxus chinensis were identified using our previous transcriptome data and named as TcJAZ1–TcJAZ9...
Epidermal growth factor (EGF) induces proliferation of epidermal and epithelial tissues in mammals. However, the effect of EGF on the single-celled eukaryotes is not well characterized, especially in the protists. Ciliates, an important group of protists, are well characterized as both pollution indicators and model organisms for research. Stylonychia lemnae, is one of the most common free-living...
Dysfunction of the monoaminergic system is critical in stress and anxiety disorders, but the role of each family member in the development of stress-related psychopathologies is not sufficiently understood. Eapp has been reported to be a transcriptional repressor of monoamine oxidase B (Maob) and down-regulates Maob via the Maob core promoter. In the present study, we more specifically examine the...
To determine the origin and evolution of goose parvovirus (GPV) and Muscovy duck parvovirus (MDPV) in the Mainland of China, phylogenetic and recombination analyses in the present study were performed on 32 complete VP1 gene sequences from China and other countries. Based on the phylogenetic analysis of the VP1 gene, GPV strains studied here from Mainland China (PRC) could be divided into three genotypes,...
In order to study whether Tnfaip3 is related to stress response and further to find it's genetic regulation, we use C57BL/6J (B6) and DBA/2 (D2) mice to built the model of chronic unpredictable mild stress. RT-PCR, Western blotting and immunohistochemistry were used for studying the expression variation of Tnfaip3 in hippocampus tissue of B6 and D2 mice after being stressed. We found that the expression...
This study aims to determine the relationship between Duffy antigen receptor for chemokines (DARC) and keloid pathogenesis. DARC expression was determined by immunohistochemistry, real-time PCR, and Western blot analysis. Cell proliferation was assessed by CCK-8 assay. Cell migration and invasion abilities were measured by the shift assay. Levels of CC chemokine ligand 2 (CCL2), CXC chemokine ligand...
Germ cells are specified by the inheritance of maternal germline determinants (preformation mode) or inductive signals from somatic cells (epigenesis mode) during embryogenesis. However, the germline specification in decapod crustaceans is unclear so far. Using vasa homolog (MnVasa) as a germ cell marker, here we probed the early events of germline specification in the oriental river prawn Macrobrachium...
The biosynthetic gene cluster for laspartomycins, a family of 11 amino acid peptide antibiotics, has been cloned and sequenced from Streptomyces viridochromogenes ATCC 29814. Annotation of a segment of 88912bp of S. viridochromogenes genomic sequence revealed the putative lpm cluster and its flanking regions which harbor 43 open reading frames. The lpm cluster, which spans approximately 60kb, consists...
