Vegetable soybeans [Glycine max (L.) Merrill] are susceptible to salt stress and, thus, soil salinity can severely affect their growth and productivity. To enhance the salt tolerance of vegetable soybeans, a novel Solanum torvum Swartz Δ1-pyrroline-5-carboxylate synthetase gene (StP5CS, GenBank accession number: JN606861) that encodes a critical regulatory enzyme in proline biosynthesis was transformed into the cultivar NY-1001 using an Agrobacteriummediated transformation method. PCR and Southern blot analyses indicated that two independent T0 fertile transgenic plants were generated. The transgenic plants transmitted the transgenes into their T1 progeny in a 3:1 ratio. The T2 and T3 homozygous transgenic lines (HTLs) were examined for salt tolerance in pot and hydroponic cultures, respectively. The StP5CS overexpression conferred salt tolerance in T2 and T3 HTLs. Under NaCl stress conditions, the leaf scorch scores of T2 and T3 HTLs were significantly lower than those of wild-type (WT) plants. The plant height, leaf area, relative chlorophyll content, and number of fresh pods of T2 and T3 HTLs were significantly higher than those of WT plants. Compared with WT plants, T2 and T3 HTLs had significantly higher levels of proline and significantly lower levels of membrane lipid peroxidation. These results indicate that StP5CS overexpression in HTLs results in enhanced salt tolerance associated with higher levels of proline accumulation under salinity stress and that StP5CS can be utilized to improve salinity tolerance in vegetable crop genetic engineering.

Backgrounds: Polymorphisms of OPRM1 A118G and ABCB1 C3435T have been suggested to contribute to inter-individual variability regarding pain sensitivity, opioid usage, tolerance and dependence and incidence of adverse effects in patients with chronic pain. This study aimed to investigate the association of both two polymorphisms with opioid requirements in Chinese patients with cancer pain. Methods: The genotypes of rs1799971 (OPRM1) and rs1045642 (ABCB1) were determined by PCR-RFLP and direct sequencing methods respectively in 112 patients with cancer-related pain. Comparisons between the different genotype or allele groups were performed with t-tests or one-way ANOVA tests, as appropriate. The potential relationship of allele number with opioid response was performed with a trend Jonckheere-Terpstra test. Results: In the 112 subjects, the frequencies of variant 118 G and 3435T allele were 38.4% and 37.9%, respectively. Significant higher 24h-opioid doses were observed in patients with GG (P=0.0004) and AG + GG (P=0.005) genotypes than the AA carriers. The dominant mutant 118G allele tended to be associated with progressively increasing 24h-opioiddoses (P=0.001). Compared with CC/CT, patients with ABCB1 TT genotype received higher 24h- and weight-surface area-adjusted-24h- opioids doses (P=0.057 and 0.028, respectively). Conclusions: The OPRM1 A118G single nucleotide polymorphism (SNP) is a key contributor for the inter-individual variability in opioidrequirements in Chinese cancer pain patients. This may possibly extend to the ABCB1 C3435T SNP.

Objective: To determine the expression of E-cadherin, ${\beta}$-catenin, and transcription factor 4 (TCF4) proteins in gastric diseases with relation to Helicobacter pylori infection. Methods: A total of 309 patients including 60 with superficial gastritis (SG), 57 with atrophic gastritis (AG) and 192 with gastric cancer (GC), were enrolled. The expression of E-cadherin, ${\beta}$-catenin, TCF4 proteins in the gastric mucosa was detected by immunohistochemistry and H. pylori infection by immunohistochemistry and PCR. Results: The expression rates of E-cadherin were significantly higher in SG and AG than in GC (P<0.01), while those of ${\beta}$-catenin in the nucleus were significantly lower in SG and AG than in GC (P<0.05). In GC cases, the expression rates of E-cadherin, ${\beta}$-catenin and TCF4 were significantly higher in the intestinal type than in the diffuse type (P<0.05). In GC patients, the expression rate of E-cadherin was significantly higher in the presence of H. pylori than in the absence of infection (P=0.011). Moreover, the expression level of TCF4 and ${\beta}$-catenin protein was significantly higher in the nucleus and cytoplasm in H. pylori positive than in H. pylori negative GC patients, especially in those with the intestinal type (all P < 0.05). Conclusion: The expression of E-cadherin and ${\beta}$-catenin progressively decreases during the process of GC tumorigenesis, while overexpression of TCF4 occurs. H. pylori infection is associated with a significant increase in the expression of E-cadherin and ${\beta}$-catenin in the cytoplasm and nucleus in GC patients, especially those with the intestinal type.

MicroRNA-223-3p (miR-223-3p) is one of the potential microRNAs that have been shown to alleviate inflammatory responses in pre-clinical investigations and is highly encased in exosomes derived from bone mesenchymal stem cells (MSC-exosomes). MSC-exosomes are able to function as carriers to deliver microRNAs into cells. Autoimmune hepatitis is one of the challenging liver diseases with no effective treatment other than steroid hormones. Here, we examined whether MSC-exosomes can transfer miR-223-3p to treat autoimmune hepatitis in an experimental model. We found that MSC-exosomes were successfully incorporated with miR-223-3p and delivered miR-223-3p into macrophages. Moreover, there was no toxic effect of exosomes on the macrophages. Furthermore, treatments of either exosomes or exosomes with miR-223-3p successfully attenuated inflammatory responses in the liver of autoimmune hepatitis and inflammatory cytokine release in both the liver and macrophages. The mechanism may be related to the regulation of miR-223-3p level and STAT3 expression in the liver and macrophages. These results suggest that MSC-exosomes can be used to deliver miR-223-3p for the treatment of autoimmune hepatitis.
