Cyrtosia septentrionalis is an achlorophyllous mycoheterotrophic orchid in the subfamily Vanilloideae (Orchidaceae). This paper reports C. septentrionalis' complete plastome sequence and compare it to other orchid plastomes with a same mycoheterotrophic nutritional mode. The C. septentrionalis plastome has decreased to 96,859 bp in length, but it still maintains a quadripartite structure. The C. septentrionalis plastome contains 38 protein-coding genes, 25 tRNA genes, and four ribosomal RNA genes. Most genes related to photosynthesis have been lost, whereas the majority of housekeeping genes remain; this pattern corresponds to the end of stage 3 gene degradation...

Plant plastomes play crucial roles in species evolution and phylogenetic reconstruction studies due to being maternally inherited and due to the moderate evolutionary rate of genomes. However, patterns of sequence divergence and molecular evolution of the plastid genomes in the horticulturally- and economically-important Lonicera L. species are poorly understood. In this study, we collected the complete plastomes of seven Lonicera species and determined the various repeat sequence variations and protein sequence evolution by comparative genomic analysis...

We provide here the first full chloroplast genome sequence, i.e., the plastome, for a species belonging to the fern order Hymenophyllales. The phylogenetic position of this order within leptosporangiate ferns, together with the general scarcity of information about fern plastomes, places this research as a valuable study on the analysis of the diversity of plastomes throughout fern evolution. Gene content of V. speciosa plastome was similar to that in most ferns, although there were some characteristic gene losses and lineage-specific differences...

Barasertib is a highly selective Aurora kinase B (AURKB) inhibitor and has been widely applied in a variety of cancer cells to investigate the regulatory function of AURKB. However, the effect of barasertib on glucose metabolism in gastric cancer (GC) remains illustrated. Here, barasertib was identified to effectively reduce glucose uptake and lactate production in GC cells in a dose-dependent and time-dependent manner. The expression levels of GLUT1, LDHA and HK2 were decreased by barasertib treatment of GC cells...

Ribosomal stress is known to increase cancer risk, however, the molecular mechanism underlying its various effects on cancer remains unclear. To decipher this puzzle, we investigated the upstream signaling pathway that might be involved in promoting ribosomal stress that leads to tumor progression. Our results suggested that inhibition of kinase PIM1 attenuated PC3 cell growth and motility following the condensed cellular body and decreased protein translation in PIM1-inhibited cells. In addition, PIM1 was found to be a component of the small 40S ribosomal subunit, and could regulate the expression of RPS7...

The relationships among the genera of the early-diverging eudicot family Berberidaceae have long been controversial. To resolve these relationships and to better understand plastome evolution within the family, we sequenced the complete plastome sequences of ten Berberidaceae genera, combined these with six existing plastomes for the family, and conducted a series of phylogenomic analyses on the resulting data set. Five of the newly sequenced plastomes were found to possess the typical angiosperm plastome complement of 79 protein-coding genes, 4 rRNA genes, and 30 tRNA genes...

DESI2 is a novel pro-apoptotic gene. We previously reported that DESI2 overexpression induces S phase arrest and apoptosis by activating checkpoint kinases. This work was to test whether the combination of endostatin, an endogenous antiangiogenic inhibitor, with DESI2 could improve the therapy efficacy in vitro and in vivo. The recombinant plasmid co-expressing DESI2 and endostatin was encapsulated with DOTAP/Cholesterol cationic liposome. Mice bearing CT26 colon carcinoma and LL2 lung cancer were treated with the DNA-liposome complex...

The NS1protein, a nonstructural protein of Tembusu virus, plays a key role in the pathogenesis of TMUV. To research host proteins that interact with NS1 protein, the cDNA library of duck embryo fibroblasts (DEF) was successfully constructed. The recombinant plasmid, pGBKT7-NS1, was transformed into the yeast Y2H to be cloned and tested for autoactivation and toxicity. The autoactivation and toxicity test of bait showed that the yeast two hybrid test could be carried out normally. A total of 7 clones from the library were got by Yeast Two-Hybrid System, and 4 proteins, including RPS7, MORC3, GABARAPL1 and MTSS1, may be interacted with DTMUV NS1 after sequencing and blast...

In general, the chloroplast genomes of angiosperms are considered to be highly conserved and affected little by adaptive evolution. In this study, we tested this hypothesis based on sequence differentiation and adaptive variation in the plastid genomes in the order Dipsacales. We sequenced the plastid genomes of one Adoxaceae species and six Caprifoliaceae species, and together with seven previously released Dipsacales chloroplasts, we determined the sequence variations, evolutionary divergence of the plastid genomes, and phylogeny of Dipsacales species...

Chondrocyte hypertrophy makes important contributions to bone development and growth. We have investigated a number of novel cartilage genes identified in a recent transcriptomic study to determine whether they are differentially expressed between different zones of equine foetal growth cartilage. Twelve genes ( ATP6V0D2 , BAK1 , DDX5 , GNB1 , PIP4K2A , RAP1B , RPS7 , SRSF3 , SUB1 , TMSB4 , TPI1 and WSB2 ) were found to be more highly expressed in the zone of hypertrophic chondrocytes than in the reserve or proliferative zones, whereas FOXA3 and SERPINA1 were expressed at lower levels in the hypertrophic zone than in the reserve zone...

PURPOSE: Anti-Müllerian hormone (AMH) and forkhead box L2 (FOXL2) are two pivotal genes expressed in human granulosa cells (hGCs) where both genes share similar inhibitory functions on activation and follicular growth in order to preserve the ovarian follicle reserve. Furthermore, AMH and FOXL2 contribute to inhibit steroidogenesis, decreasing or preventing the activation of gonadotrophin-dependent aromatase CYP19A1 cytochrome P450 family 19 subfamily A member 1 (CYP19A1). The purpose of this study is to evaluate the role of AMH in regulating the expression of FOXL2...

Ubiquitinlation of proteins is prevalent and important in both normal and pathological cellular processes. Deubiquitinating enzymes (DUBs) can remove the ubiquitin tags on substrate proteins and dynamically regulate the ubiquitination process. The PPPDE family proteins were predicted to be a novel class of deubiquitinating peptidase, but this has not yet been experimentally proved. Here we validated the deubiquitinating activity of PPPDE1 and revealed its isopeptidase activity against ubiquitin conjugated through Lys 48 and Lys 63...

Cyrtomium falcatum is a popular ornamental fern cultivated worldwide. Native to the Korean Peninsula, Japan, and Dokdo Island in the Sea of Japan, it is the only fern present on Dokdo Island. We isolated and characterized the chloroplast (cp) genome of C. falcatum, and compared it with those of closely related species. The genes trnV-GAC and trnV-GAU were found to be present within the cp genome of C. falcatum, whereas trnP-GGG and rpl21 were lacking. Moreover, cp genomes of Cyrtomium devexiscapulae and Adiantum capillus-veneris lack trnP-GGG and rpl21, suggesting these are not conserved among angiosperm cp genomes...
