Abstract

Objective: To investigate whether HBV genotype influences HBV DNA and RNA responses to tenofovir(TDF) and telbivudine(LDT) in pregnant women with HBeAg-positive in Guizhou. Methods: This was a retrospective analysis of 75 pregnant women hepatitis B with HBsAg and HBeAg double-positive(19-38 years old, median age 26 years old), who were enrolled in the Department of Infectious Diseases and Obstetrics Clinic of the Affiliated Hospital of Guizhou Medical University from May 2016 to July 2017.Blood samples were collected at 12-24, 28-32 and 36-40 weeks of pregnancy for analyses of genotype, including hepatitis B surface antigen(HBsAg), hepatitis B e antigen (HBeAg), HBV DNA, HBV RNA and liver function, alanine transaminase(ALT), aspartate transaminase(AST), total bilirubin(TBiL), total bile acids(TBA), cholinesterase(CHE), alkaline phosphatase (ALP). Continuous variable was adopted by means of mean+/-standard deviation, and categorical variables were used for statistical analysis. Results: The HBV genotype was B in 64.0%(48/75)and C in 36.0%(27/75). The TDF and LDT groups showed no differences in demographic and clinical characteristics, including liver function tests, HBsAg, HBeAg, log(10)HBV DNA and log(10)HBV RNA.TDF groups, pre-treatment: HBV DNA (4.8+/-2.0), HBV RNA (6.4+/-1.1); at 4 weeks of treatment: HBV DNA (4.0+/-0.8), HBV RNA (6.0+/-0.9); at the end of treatment: HBV DNA (3.1+/-0.7), HBV RNA (5.5+/-0.8). LDT groups, pre-treatment HBV DNA (5.1+/-2.0), HBV RNA(6.5+/-0.9); at 4 weeks of treatment: HBV DNA (4.4+/-1.2), HBV RNA(6.5+/-0.8); at the end of treatment: HBV DNA(3.5+/-1.2), HBV RNA (6.1+/-0.7). Compared with pre-treatment (12-24 weeks), the TDF and LDT group showed significant reductions in log(10)(HBV DNA) and log(10)(HBV RNA) at 36-40 weeks ( P<0.05). Under the influence of excluding other variables, the genotype had a certain influence on the HBV RNA load.That was, HBV RNA in patients with the C genome decreased by 0.54 units(log(10)) at the end of the treatment compared to patients with the B genome, and the P value was less than 0.05. Conclusion: B and C genotypes are predominant in pregnant women with hepatitis B in Guizhou Province. B-type viruses are more easily controlled when different genotypes are treated with nucleotide analogues.

Abstract

Polyhydroxyalkanoates are polyesters synthesized by numerous microorganisms. These polyesters are biodegradable and have similar properties to those of conventional plastics. Cupriavidus taiwanensis strain 184 is phylogenetically related to the well-known polyhydroxybutyrate (PHB) producer Ralstonia eutropha (Cupriavidus necator) and is also shown to be able to accumulate significant amounts of PHB. In this study, we cloned the PHB synthesis genes (phaCAB) from C. taiwanensis 184 into Escherichia coli for biosynthesis of PHB. The recombinant E. coli strains were able to synthesize significant amounts of PHB. The PHB amounted to about 66~70% of total cell material of these recombinant strains.

Abstract

The high degree of similarity between the mouse and human genomes is demonstrated through analysis of the sequence of mouse chromosome 16 (Mmu 16), which was obtained as part of a whole-genome shotgun assembly of the mouse genome. The mouse genome is about 10% smaller than the human genome, owing to a lower repetitive DNA content. Comparison of the structure and protein-coding potential of Mmu 16 with that of the homologous segments of the human genome identifies regions of conserved synteny with human chromosomes (Hsa) 3, 8, 12, 16, 21, and 22. Gene content and order are highly conserved between Mmu 16 and the syntenic blocks of the human genome. Of the 731 predicted genes on Mmu 16, 509 align with orthologs on the corresponding portions of the human genome, 44 are likely paralogous to these genes, and 164 genes have homologs elsewhere in the human genome; there are 14 genes for which we could find no human counterpart.

Abstract

A 2.91-billion base pair (bp) consensus sequence of the euchromatic portion of the human genome was generated by the whole-genome shotgun sequencing method. The 14.8-billion bp DNA sequence was generated over 9 months from 27,271,853 high-quality sequence reads (5.11-fold coverage of the genome) from both ends of plasmid clones made from the DNA of five individuals. Two assembly strategies-a whole-genome assembly and a regional chromosome assembly-were used, each combining sequence data from Celera and the publicly funded genome effort. The public data were shredded into 550-bp segments to create a 2.9-fold coverage of those genome regions that had been sequenced, without including biases inherent in the cloning and assembly procedure used by the publicly funded group. This brought the effective coverage in the assemblies to eightfold, reducing the number and size of gaps in the final assembly over what would be obtained with 5.11-fold coverage. The two assembly strategies yielded very similar results that largely agree with independent mapping data. The assemblies effectively cover the euchromatic regions of the human chromosomes. More than 90% of the genome is in scaffold assemblies of 100,000 bp or more, and 25% of the genome is in scaffolds of 10 million bp or larger. Analysis of the genome sequence revealed 26,588 protein-encoding transcripts for which there was strong corroborating evidence and an additional approximately 12,000 computationally derived genes with mouse matches or other weak supporting evidence. Although gene-dense clusters are obvious, almost half the genes are dispersed in low G+C sequence separated by large tracts of apparently noncoding sequence. Only 1.1% of the genome is spanned by exons, whereas 24% is in introns, with 75% of the genome being intergenic DNA. Duplications of segmental blocks, ranging in size up to chromosomal lengths, are abundant throughout the genome and reveal a complex evolutionary history. Comparative genomic analysis indicates vertebrate expansions of genes associated with neuronal function, with tissue-specific developmental regulation, and with the hemostasis and immune systems. DNA sequence comparisons between the consensus sequence and publicly funded genome data provided locations of 2.1 million single-nucleotide polymorphisms (SNPs). A random pair of human haploid genomes differed at a rate of 1 bp per 1250 on average, but there was marked heterogeneity in the level of polymorphism across the genome. Less than 1% of all SNPs resulted in variation in proteins, but the task of determining which SNPs have functional consequences remains an open challenge.
