Abstract
OBJECTIVE To evaluate the expression level of melatonin and its effects on immune function in aplastic anemia (AA) patients. METHODS The enzyme-linked immunosorbent assay (ELISA) was used to detect the plasma levels of melatonin in AA patients, and the correlation between melatonin levels and laboratory indexs was analyzed. The activation, proliferation, and apoptosis of T cells from AA patients were analyzed by flow cytometry with or without melatonin in vitro. RESULTS The plasma levels of melatonin in AA patients were significantly lower compared with healthy controls (HC) (12.23 pg/ml vs 20.04 pg/ml, P < 0.01), while the plasma melatonin levels of AA patients in remission group after immunosuppressive therapy (IST) were significantly higher than those in non-remission group (29.16 pg/ml vs 11.73 pg/ml, P =0.04). Moreover, the melatonin levels were positively correlated with platelets (r =0.49), the absolute reticulocyte count (r =0.45), and the percentage of neutrophils (r =0.43). Meanwhile, there was a negative correlation between melatonin levels and the percentages of lymphocytes (r =-0.45). The expressions of CD25 and CD69 in both CD4+ and CD8+ T cells from AA patients were remarkably inhibited by melatonin in vitro (all P < 0.05). When cultured with melatonin, the proliferation rates of both CD4+ and CD8+ T cells from AA patients were markedly suppressed (P =0.01 andP < 0.01). CONCLUSION The plasma levels of melatonin were decreased in AA patients, which might play an important role in the mechanism of immunological abnormalities. The hyperimmune status of AA patients could be partially ameliorated by melatonin in vitro.

Abstract
OBJECTIVE To explore the difference of lymphocyte subsets in peripheral blood (PB) between aplastic anemia (AA) and hypoplastic myelodysplastic syndrome (hypo-MDS) patients, meanwhile to compare the clinical parameters obtained from PB and bone marrow (BM). METHODS The lymphocyte subsets in hypo-MDS (n=25) and AA (n=33) patients were investigated by flow cytometry. Meanwhile, the differences in PB cell counts, biochemical indicators, BM cell counts and abnormal chromosomes between the two groups were analyzed. RESULTS The percentage of CD8+T cells in AA group was significantly higher than that in hypo-MDS group (P=0.001), while the percentage of CD4+ T cells and the CD4+/CD8+ ratio in AA group were obviously lower than those in hypo-MDS group (P=0.015 and 0.001, respectively). Furthermore, the proportion of CD4+ and CD8+ activated T (TA) cells, and memory Tregs in AA group was distinctly lower than those in hypo-MDS group (P=0.043, 0.015 and 0.024, respectively). Nevertheless, the percentage of CD8+ naive T (TN) cells in AA patients was remarkably higher (P=0.044). And hypo-MDS patients had declined lymphocyte counts (P=0.025), increased levels of total bilirubin (TBil), lactate dehydrogenase (LDH), vitamin B12 and proportion of BM blasts than AA patients (P=0.019, 0.023, 0.027 and 0.045, respectively). CONCLUSION In this study it was confirmed that the percentages of CD4+ and CD8+ TA cells, memory Tregs and CD8+ TN cells were significantly different between AA and hypo-MDS patients, which provide an essential basis for the identification of these two diseases.

Abstract
Melatonin confers protection against myocardial injury by reducing inflammation and inhibiting apoptosis. In the present study, we investigated whether melatonin regulates cardiomyocyte proliferation and improves cardiac function in rats with myocardial infarction (MI). Two MI models were established in vitro (H9c2 cells were cultured under hypoxia) and in vivo (the left anterior descending coronary artery of rats was surgically ligated). miR-200b-3p and high mobility group box 1 (HMGB1) levels were detected. Cell proliferation and apoptosis were analyzed in vitro, and cardiac function, inflammatory cytokines, and myocardial injury markers in vivo were tested. The experimental results reported that melatonin promoted proliferation and impaired apoptosis of H9c2 cells cultured in hypoxia. In vivo, melatonin improved cardiac function and inhibited the inflammation and myocardial injury of rats with MI. miR-200b-3p was downregulated and HMGB1 was upregulated in MI, while melatonin could upregulate miR-200b-3p and downregulate HMGB1. The HMGB1 was targeted by miR-200b-3p. Upregulating miR-200b-3p or downregulating HMGB1 could further promote the therapeutic effect of melatonin, and downregulating miR-200b-3p or upregulating HMGB1 could abolish the therapeutic effect of melatonin. In conclusion, melatonin alleviates inflammation and cardiac dysfunction after MI by regulating the miR-200b-3p/HMGB1 axis, offering a new therapeutic strategy for MI.

Abstract
Inbred pigs are promising animal models for biomedical research and xenotransplantation. Established in 1980, the Banna minipig inbred (BMI) line originated from a sow and its own male offspring. It was selected from a small backcountry minority Lahu village, where records show that no other pig breed has ever been introduced. During the inbreeding process, we perfomed extreme inbreeding over 23 consecutive generations using full-sibling or parent-offspring mating. In order to investigate the inbreeding effects in BMI pigs across generations over the past 40 years, in this study we conducted a genome-wide SNP genotyping of the last 10 generations, representing generations 14-23. In total, we genotyped 57,746 SNPs, corresponding to an average decrease in heterozygosity rate of 0.0078 per generation. Furthermore, we were only able to identify 18,216 polymorphic loci with a MAF larger than 0.05, which is substantially lower than the values in previous reports on other pig breeds. In addition, we sequenced the genome of the first pig in the twenty-third generation (inbreeding coefficient 99.28%) to an average coverage of 12.4× to evaluate at the genome level the impact of advanced inbreeding. ROH analysis indicates that BMI pigs have longer ROHs than Wuzhishan and Duroc pigs. Those long ROH regions in BMI pigs are enriched for distinct functions compared with the highly polymorphic regions. Our study reveals a genome-wide allele diversity loss during the progress of inbreeding in BMI pigs and characterizes ROH and polymorphic regions as a result of inbreeding. Overall, our results indicate the successful establishment of the BMI line, which paves the way for further in-depth studies.

Abstract
Parathyroid hormone-related protein (PTHrP) is involved in the deposition of milk calcium in mammal lactation, but its role in buffalo is unclear. In this study, the full-length coding sequence of the water buffalo PTHrP gene was first isolated using reverse transcription-polymerase chain reaction. The protein was then subjected to molecular characterization using bioinformatic methods, and the tissue expression pattern was further assayed by semi-quantitative reverse-transcription polymerase chain reaction. The water buffalo PTHrP gene contains an open reading frame of 534 base pairs encoding a polypeptide of 177 amino acid residues, a theoretical molecular weight of 20.32 kDa, and an isoelectric point of 10.00. In addition, water buffalo PTHrP was predicted to contain a signal peptide, a typical hydrophobic region with no hydrophobic transmembrane regions, and to exert its function in the cell nucleus. A conserved domain of parathyroid superfamily from amino acids 34-114 was observed in the polypeptide. Sequence comparison and the phylogenetic analysis showed that the sequence of the water buffalo PTHrP protein shared high homology with that of other mammals, particularly cattle and goat. Among the 16 tissues examined, the PTHrP gene was only expressed in adipose tissue, placenta, uterine wall, hypophysis, and mammary gland tissue, but gene expression levels were higher in the uterus wall and adipose tissue. The results of this study suggest that the PTHrP gene plays an important role in the deposition of milk calcium of water buffalo.

Abstract
The lymphotoxin beta receptor (LTβR) is a member of the tumor necrosis factor family of receptors (TNFR). It plays a role in regulating lymphoid organogenesis and homeostasis of the immune system. In the present study, the full coding region of a putative LTβR gene of Sus scrofa was amplified by reverse transcription-polymerase chain reaction (RT-PCR) and cloned for the first time (accession Nos. JX457347 and AFU74012). In addition, analysis of the tissue expression profile was carried out via RT-PCR. The full-length coding region of porcine LTβR had 1266 nucleotides (molecular weight, 45.61 kDa; pI, 5.71) and encoded 421 amino acids. Bioinformatic prediction indicates that LTβR belongs to the TNFR superfamily and contains a TNFR domain. The sequence homology analysis revealed that the amino acid sequences of S. scrofa LTβR had 82.9, 82.4, 81.3, 80.5, 78.7, 74.6, and 73.0% identity with those of Equus caballus, Canis lupus, Ailuropoda melanoleuca, Oryctolagus cuniculus, Bos taurus, Mus musculus, and Homo sapiens, respectively. The phylogenetic tree based on the amino acid sequences of LTβR from 8 species revealed that S. scrofa was more closely related to E. caballus, C. lupus, and A. melanoleuca. RT-PCR analysis showed that the porcine LTβR gene was differentially expressed (e.g., high, moderate, low, or nonexistent) in various tissues (e.g., prostate, pituitary, brainstem, and esophagus, respectively). This may be related to differences in the regulation of LTβR in the different tissues.

Abstract
The activity-regulated cytoskeletal associated protein (Arc/Arg3.1) has been implicated in experience-dependent synaptic plasticity and memory formation. However, information regarding its coding gene in buffalo remains scarce. In this study, the full-length of Arc/Arg3.1 was isolated and characterized (accession No. JX491649) and genetic variations of six river buffalo and eight swamp buffalo were investigated. A tissue expression profile was obtained using semi-quantitative reverse transcription-polymerase chain reaction. The coding region sequence of Arc/Arg3.1 contained 1191 nucleotides encoding a putative protein of 396 amino acids with a theoretical isoelectric point (pI) and molecular weight (Mw) of 5.4 and 45.2 kDa, respectively. Four polymorphisms (c.63T>C, c.228T>C, c.558G>A, and c.625G>C) were found in buffalo; however, only substitution c.625G>C was non-synonymous, leading to an amino acid change from Val to Leu at the 209th position of the Arc/Arg3.1 protein sequence. Bioinformatics analysis revealed that this substitution had no significant effect on Arc/Arg3.1 function (subPSEC = -1.4039, Pdeleterious = 0.1685), which indicated that Arc/Arg3.1 was highly conserved and functionally important in buffalo. Phylogenetic analysis revealed that the gene is closely related to that of Bos taurus and Bos grunniens. The gene was moderately expressed in the hypophysis and the placenta; it was weakly expressed in the kidney, milk, mammary gland, cerebrum, lung, heart, rumen, fat, and uterus; and it was almost silent in the muscle, liver, and skin. These findings will provide further insights into the structure and function of the immediate-early gene in buffalo.

Abstract
The complete coding sequences (CDSs) of "Yunnan Purple Pepper No.1" (Capsicum annuum L.) AN2 and UPA20 genes were amplified using the reverse transcriptase polymerase chain reaction on the basis of the conserved sequence information of some Solanaceae plants and known highly homologous pepper expressed sequence tags. The nucleotide sequence analysis of these 2 genes revealed that pepper AN2 gene encoded a protein of 263 amino acids that has high homology with the AN2-like protein of 4 species: tobacco, tomato, potato, and petunia. The UPA20 gene encoded a protein of 341 amino acids that has high homology with the proteins of 3 species: tobacco, petunia, and tomato. The tissue expression analysis indicated that the pepper AN2 gene was overexpressed in the pericarp and placenta; moderately in stems, flowers, and seeds; and weakly in the roots, leaves, and pericarp. The pepper UPA20 gene was overexpressed in the flowers and seeds; moderately expressed in the roots and stems; and weakly expressed in the leaves and placenta. Our findings might form the basis for further research on these 2 pepper genes.

Abstract
We isolated two TATA-binding protein-associated factor (TAF) genes, TAF10 and TAF13, from pepper (Capsicum annuum). The complete coding sequences were amplified using reverse transcriptase-PCR on the basis of conserved sequence information of eggplant and several other plant species. Nucleotide sequence analysis of these two genes revealed that the pepper TAF10 gene encodes a protein of 103 amino acids that belongs to the TAF10 superfamily. The pepper TAF10 gene was highly expressed in the pericarp and placenta, moderately expressed in the stems, flowers, seeds and leaves, and weakly expressed in roots. The TAF13 gene was found to encode a protein of 130 amino acids that belongs to the TAF13 superfamily. The TAF13 gene was highly expressed in the stems, flowers and pericarp, moderately expressed in the leaves, placenta and seeds, and weakly expressed in roots.

Abstract
The relative isotopic abundance (RIA) measurement errors of a quadrupole time-of-flight (Q-ToF) instrument incorporating analog-to-digital converter detectors were systemically evaluated by stochastically collecting about 200 data in positive ion mass spectrometry (MS) mode. Errors varied with peak intensities at definite spectral acquisition rates but were very close, even if peak intensities changed sharply at different spectral acquisition rates with the same concentration. Intensity thresholds were systematically defined at 1 Hz of spectral acquisition rates. RIA measurement errors were also evaluated using peak area. It seemed that peak area was better adapted for the high-intensity ions while peak intensity was suited for very low-intensity ions. Several known compounds were selected for RIA measurements for product ions in tandem mass spectropmetry (MS/MS) mode. An extract of a representative traditional Chinese medicinal, Paederia scandens was analyzed with high-performance liquid chromatography-electrospray ionization-QToF-MS/MS. The unique elemental compositions of some compounds could not be identified even with exact masses and MS/MS spectra of measured and reference compounds. RIA errors, especially of (M+2)M(-1), provided vital information for determining the elemental composition.
