Disease Association and Druggability of WD40 Repeat Proteins.

WD40 repeat (WDR) domains are protein interaction scaffolds that represent one of the largest protein families in human, and a first WDR inhibitor-an allosteric antagonist of polycomb repressive complex 2-just entered the clinic. A systematic analysis of the CORUM database of protein complexes shows that WDR is the most represented domain in transcriptional regulation and one of the most prevalent in the ubiquitin proteasome system, two pathways of high relevance to drug discovery. Parsing the literature and the vulnerability of cancer cell lines to CRISPR knockout indicates that WDR proteins are targets of interest in oncology and other disease areas.

Significant genetic differentiation of Gobiopterus lacustris, a newly recorded transparent goby in China.

In our recent survey, the transparent small Lacustrine goby, Gobiopterus lacustris had reported as the endemic species of Luzon, Philippines, was identified as an abundant species in mangroves of Leizhou Peninsula, China. Here, high diversity and significant differentiation of five sites of samples representing the west and east populations were revealed by mitochondrial DNA sequences. Five haplotypes of 56 cytochrome oxidase subunit I (Cox1) with the lengths of 623 base pairs (bp) have the high pairwise identity (>98.

Morphological Characters and Transcriptome Profiles Associated with Black Skin and Red Skin in Crimson Snapper (Lutjanus erythropterus).

In this study, morphology observation and illumina sequencing were performed on two different coloration skins of crimson snapper (Lutjanus erythropterus), the black zone and the red zone. Three types of chromatophores, melanophores, iridophores and xanthophores, were organized in the skins. The main differences between the two colorations were in the amount and distribution of the three chromatophores.

DNA barcoding South China Sea fishes.

We have determined 222 DNA barcode sequences of 95 fish species in 86 genera of 69 families from 15 orders. Fish were captured by trawl from two important fisheries regions in South China Sea: Spratly Islands (Nansha Islands) and Beibu Gulf. The average genetic distances between intraspecies were about 60-fold less than those of interspecies within different taxonomic levels, as Kimura two-parameter genetic distances averaged 17.

DNA barcoding, phylogenetic relationships and speciation of snappers (genus Lutjanus).

The phylogenetic relationships of 13 snapper species from the South China Sea have been established using the combined DNA sequences of three full-length mitochondrial genes (COI, COII and CYTB) and two partial nuclear genes (RAG1, RAG2). The 13 species (genus Lutjanus) were selected after DNA barcoding 72 individuals, representing 20 species. Our study suggests that although DNA barcoding aims to develop species identification systems, it may also be useful in the construction of phylogenies by aiding the selection of taxa.

[Rapid isolation and characteristics analysis of microsatellites from Lutjanus russelli].

The (CA)n DNA sequences in Lutjanus russelli were isolated through PCR arrays, and the characteristics of the microsatellite were analyzed. DNA was extracted from a sample of Lutjanus russelli, and digested with Hae+Dra. The fragments were ligated to pUCm-T vector and transferred into DH5alpha to construct a genomic library.
