A stand-alone BLAST server is available that provides a convenient and amenable platform for the analysis of molluscan sequence information especially the EST sequences generated by traditional sequencing methods. However, it is found that the server has limitations in the annotation of molluscan sequences generated using next-generation sequencing (NGS) platforms due to inconsistencies in molluscan sequence available at NCBI. We constructed a web-based interface for a new stand-alone BLAST, called PANM-DB (Protostome DB) for the analysis of molluscan NGS data. The PANM-DB includes the amino acid sequences from the protostome groups-Arthropoda, Nematoda, and Mollusca downloaded from GenBank with the NCBI taxonomy Browser. The sequences were translated into multi-FASTA format and stored in the database by using the formatdb program at NCBI. PANM-DB contains 6% of NCBInr database sequences (as of 24-06-2015), and for an input of 10,000 RNA-seq sequences the processing speed was 15 times faster by using PANM-DB when compared with NCBInr DB. It was also noted that PANM-DB show two times more significant hits with diverse annotation profiles as compared with Mollusks DB. Hence, the construction of PANM-DB is a significant step in the annotation of molluscan sequence information obtained from NGS platforms. The PANM-DB is freely downloadable from the web-based interface (Malacological Society of Korea, http://malacol.or/kr/blast) as compressed file system and can run on any compatible operating system.

This study was to evaluate the protein profile of seminal plasma using 2-DE in Hanwoo. Seminal plasma was harvested from five mature Hanwoo, and seminal plasma protein was extracted by M-PER Mammalian Protein Extraction Reagent. Proteins were refined by clean-up kit and quantified by Bradford method until total protein was $300\;{\mu}l$. Immobilized pH gradient (IPG) strip was used 18 cm and 3~11 NL. SDS-PAGE was used 12% acrylamide gel. Each gels were visualized by comassie brilliant blue and silver staining. These spots were analyzed by MALDI-TOF MS and searched on NCBInr. The result, 20 proteins of 36 protein spots were searched through peptide sequencing on the NCBInr. 8 proteins profiled by 2-DE were proved through previous bovine studies and the name of each protein was albumin, nucleobindin, clusterin, TIMP-2, spermadhesin Z13, spermadhesin-1 and BSP proteins (BSP 30 kDa and BSP A1/A2). 12 new proteins were ATP synthase, protein MAK16 homolog, Transmembrane protein 214, E3 ubiquitin-protein ligase BRE1A, dual serine/threonine and tyrosine protein kinase, tissue factor pathway inhibitor 2, alpha-actinin-4, RUN domain-containing protein 3B, catenin alpha-1, protein-glutamine gamma-glutamyltransferase 2, plakophilin-1 and inter-alpha-trypsin inhibitor heavy chain H1 has not been previously described in the bovine seminal plasma study. These proteins may be contribute to define the type of proteins affecting fertility of male and improve the fertilizing ability of semen in Hanwoo.

Although action modes of equol and genistein have been extensively studied, their precise roles in tumor cells remain elusive. To address possible effects of these compounds on protein expression in mammary tumor cells, proteins modulated in MCF-7 mammary tumor cells when incubated in absence and presence of 10 uM equol or genistein were identified through 2-dimensional gel electrophoresis, MALDI-TOF MS/MS, and NCBInr database search using Mascot software. Most proteins differentially expressed in MCF-7 cells after treatment with 10 uM genistein or equol were identified as being the same. Exposure to both compounds caused decreased cellular expression of RNA-binding protein regulatory subunit and oncogene DJ1 tubulin beta-1 chain, and increased expression of heterogeneous ribonucleoproteins F and L, KH-type splicing regulatory protein, and translation elongation factor EF-Tu precursor. Genistein and equol at dose used in this study showed common action mechanism.

When fully grown oocytes are removed from their follicles, they can resume meiosis and mature spontaneously under in vitro conditions. However, nuclear maturation under in vitro condition is not accompanied by complete cytoplasmic maturation, which is essential for successful fertilization and the initiation of zygotic development. This study analyzed change of proteins in follicular fluids during the porcine follicular development. Follicular fluids were collected from follicles of diameter 1~2 mm, 2~6 mm and 6~10 mm in ovary of slaughtered pigs. Total proteins were extracted from follicular fluids by M-PER Mammalian Protein Extraction Reagent. We confirmed totally 27 same spots, 1 spot from follicle fluid of 2~6 mm follicle and 5 spots from follicle fluid of 6~10 mm in diameter were analyzed by MALDI mass spectrometry and searched on NCBInr. In results, spot No. 28 from 2~6 mm follicle was Ig lambda chain C region, and spot No.32 and 33 from 6~10 mm was Apolipoprotein A-(APOA4). Spot No.29 and 31 were failed to analyze. These results indicate that the porcine oocyte during in vitro maturation depend on specific different expressed proteins may play an important roles in the sequence of molecular events in porcine oocyte maturation and follicular development.

Nonsteroidal anti-inflammatory drugs such as indomethacin (IN) can exert anti-colorectal cancer (CRC) activity through cyclooxygenase independent mechanism, but the exactly biological mechanism is not completely known. Here we use proteomic tools to investigate the molecular mechanism of this action. First, nude mice bearing tumors derived from subcutaneous injection with human CRC cell line HCT116 were randomly allocated to groups treated with or without indomethacin. Later, tumor lumps were incised and then total proteins extracted. After separated with two-dimensional electrophoresis, thirty-one differently expressed spots were found between IN-treated and non-IN-treated groups, of which 25 spots decreased and 6 spots increased in abundance in IN-treated group. Through matrix-assisted laser desorption ionization time of flight mass spectrometry and then NCBInr and SWISS-PROT databases searching, 12 protein spots were finally identified including galectin-1, annexin A1, annexin IV, trancription factor BTF3A, calreticulin. Most of the identified proteins are correlated with tumor's biological prosperities of proliferation, invasion, apoptosis and immunity, or take part in cell's signal transduction. From above we thought that indomethacin can exert its effect on colorectal cancer through regulating several proteins' expression directly or indirectly. Further study of these proteins may be helpful in founding new targets of drugs for cancer chemotherapy.

This study analyzed change of proteins in granulosa cells during the porcine follicuar development by proteomics techniques. Granulosa cells of the follicles, of which the diameter is $2{\sim}4\;mm$ and $6{\sim}10\;mm$, were collected from ovary of slaughtered pig that each follicle of diameter $1{\sim}4\;mm$ and $6{\sim}10\;mm$. We extracted glanulosa cell proteins by M-PER Mammalian Protein Extraction Reagent. Proteins were refined by clean-up kit and quantified by Bradford method until total protein was $200{\mu}l$. Immobilized pH gradient(IPG) strip used 18 cm, $3{\sim}10\;NL$. SDS-PAGE used 10% acrylamide gel. After silver staining, Melanie 7 and naked eye test were used for spot analyzation. Increasing proteins in glanulosa cell of $6{\sim}10\;mm$ follicle were 7 spots. This spots were analyzed by MALDI-TOF MS and searched on NCBInr. In results, 7 spots were similar to zinc/ling finger protein 3 precursor (RING finger protein 203), angiomotin, heat shock 60 kDa protein 1 (chaperonin) isoform 1 (HSP60), similar to transducin-like enhancer protein 1 (TLE 1), SH3 and PX domains 2A (SH3PXD2A). Those proteins were related with transfer between cells. Increase of proteins has an effect on follicular development.

Wheat (Triticum aestivum L.) grain texture is an important determinant of milling properties and end product use. Two linked genes, puroindoline a (PINA) and puroindoline b (PINB), control most of the genetic variation in wheat grain texture. Wheat seed proteins were examined to identify PINA and PINB gene using two pre-harvest sprouting wheat cultivars; Jinpum (resistant) and Keumgang (susceptible).Wheat seed proteins were separated by two-dimensional electrophoresis with IEF gels over pH ranges: pH 3-10. A total of 73 spots were digested with trypsin resulting peptide fragmentation were analyzed by matrix assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF/MS). Mass spectra were automatically processed and searched through NCBInr, SWISS-PORT and MSDB database with mono isotopic masses and complete gene sequence were found by UniProt database. Puroindoline a and puroindoline b that is responsible for grain texture related with baking performance and roughness. Two spots were found Pin b (16.7 kDa) and Pin a (16.3 kDa) in Jinpum compare to seven spots were identified Pin a (16.1 kDa, 16.3 kDa) and Pin b (16.7 kDa, 9.5 kDa and 14.4 kDa) in Keumgang. Some selected spots were identified puroindoline like grain softness protein (16.9 kDa, 17 kDa and 18.1 kDa) in Keumgang. Moreover, to gain a better inferring the identification of puroindoline related proteins using proteomics, we accomplished a complete gene sequence of PINA and PINB gene in pre-harvesting sprouting wheat seeds between resistant (Jinpum) and susceptible (Keumgang).

It was conducted the experiment, divided into three groups as normal, poor and polycystic ovary syndrome, to detect the change of protein patterns in follicular fluid on ovarian response following controlled ovarian hyperstimulation for human IVF outcome. In the normal group, it was confirmed reproducible 57 spots in the detected total 81 spots. Then 1 spot was not found in the other groups. In the poor responder group, it was found reproducible 53 spots in the detected total 98 spots. 6 spots were down-regulation and 7 spots were up-regulation comparable with normal group. There were not 5 spots in poor responder group comparable with other groups. In the polycystic ovary syndrome group, it was expressed reproducible 53 spots in the detected total 80 spots and 3 spots were just expressed in this group. However, 4 spots were not found in polycystic ovary syndrome. 9 spots were up-regulation comparable with normal group. Significant up and down-regulation spots among the each groups were identified. The results were a cytosolic carboxypeptidase, a signal-induced proliferation-associated protein 1, a ceruloplasmin, a keratin(type II cytoskeletal 1), a polypeptide N-acetylgalactosantinyltransferase 2, a serine/threonine-protein phosphatase 4 regulatory subunit 4. It was identified that 8 spots, 6 kinds of protein are corresponded with NCBInr database research, but 10 spots were failed in the identification. In conclusion, it has been confirmed change and expression of protein on the ovarian response following COH of human.
