Prostaglandin $E_2$(PG$E_2$) is an abundant eicosanoid in bone that has been implicated in a number of pathological states associated with bone loss, and is also known to stimulate matric metalloproteinase-1 systhesis and secretion in rat and human osteoblast cells, although the intracellular reaction remain unclear. Interleukin-1$\beta$ (IL-1$\beta$) is a cytokine that plays a critical role in bone remodelling and appears to act as a downstream effector of most bone-resorbing agents. However, it is still interesting to examine whether PG$E_2$ regulates IL-1$\beta$ expression by mouse osteoblasts or not. Here we demonstrate that PG$E_2$is a potent inducer of IL-1$\beta$ production by fetal osteoblasts.

The purpose of this research was to investigate the effects of 50% ethylalcohol extracts of Lespedeza cuneata G. Don (LE) on the activity of murine immune cells. LE was administered orally once a day for 7 days at the dose of 250 mg/kg. LE increased the cell viability of thymocytes, splenocytes and peritoneal macrophages in vitro and in vivo system, but decreased the cell viability of thymocytes and splenocytes in the presence of concanavalin A in vivo system. Also, the administration of LE was increased the production of ${\gamma}$-interferone, but did not affect the production of interleukin-2 and interleukin-4. Furthermore, LE decreased the phagocytic activity of peritoneal macrophages in vitro and in vivo system, but enhanced the production of nitric oxide. These results suggest that LE has a immuno-regulative action via stimulation of immune cells proliferation.

Arginine deiminase (ADI, E.C. 3.5.3.6), one of the arginine deprivation enzymes, exhibits anticarcinogenic activities. The present study investigated the anti-inflammatory activities of the purified recombinant ADI originating from Lactococcus lactis ssp. lactis ATCC7962 (LADI). LADI dose-dependently inhibited lipopolysaccharide (LPS)-induced upregulation of inducible nitric oxide synthase and the production of nitric oxide in RAW 264.7 murine macrophages. The induction of cyclooxygenase-2 expression and subsequent production of prostaglandin $E_2$ by LPS was also attenuated by LADI treatment. Moreover, LADI inhibited the production of interleukin-6 in LPS-stimulated RAW 264.7 macrophages. These results indicate that LADI exerts anti-inflammatory effects, which may in part explain its chemopreventive potential.

Purpose: Gastric cancer (GC) is the second most lethal cancer globally and is associated with poor prognosis. Fatty acid-binding proteins (FABPs) can regulate biological properties of carcinoma cells. FABP5 is overexpressed in many types of cancers; however, the role and mechanisms of action of FABP5 in GC remain unclear. In this study, we aimed to evaluate the clinical and biological functions of FABP5 in GC. Materials and Methods: We assessed FABP5 expression using immunohistochemical analysis in 79 patients with GC and evaluated its biological functions following in vitro and in vivo ectopic expression. FABP5 targets relevant to GC progression were determined using RNA sequencing (RNA-seq). Results: Elevated FABP5 expression was closely associated with poor outcomes, and ectopic expression of FABP5 promoted proliferation, invasion, migration, and carcinogenicity of GC cells, thus suggesting its potential tumor-promoting role in GC. Additionally, RNA-seq analysis indicated that FABP5 activates immune-related pathways, including cytokine-cytokine receptor interaction pathways, interleukin-17 signaling, and tumor necrosis factor signaling, suggesting an important rationale for the possible development of therapies that combine FABP5-targeted drugs with immunotherapeutics. Conclusions: These findings highlight the biological mechanisms and clinical implications of FABP5 in GC and suggest its potential as an adverse prognostic factor and/or therapeutic target.

The present study was performed to assess the worth of using the by products for seaweed (Eucheuma spinosum) ethanol production process (SEPPB) as broiler feeds. For this purpose, 225 broiler chicks (white mini broilers) were used as experimental animals. The control (Control group) was fed with the broiler feeds. 5% mixture (5% SEPPB group) was fed with a 5% SEPPB mixture feeds, and the 10% mixture (10% SEPPB group) was fed with a 10% SEPPB group mixture feeds. The experiment was repeated for five times and 15 birds were assigned in each experiment and the experimental period was five weeks. There was no difference in the rate of weight gain until the second week of the 5% SEPPB group and 10% SEPPB group. However, the weight gain rate was increased to 6.2% for the 5% SEPPB group and 11.4% for the 10% SEPPB group as compared to the Control group at the third weeks of the experimental period. There was no statistical significant difference in terms of feed FCR and feed intake. Analyses of the quality of chicken breasts showed that pH was 2.5% higher in the 5% SEPPB group and 2.3% higher in the 10% SEPPB group. Shearing force was 31.3% lower in the 5% SEPPB group and 14.7% lower in the 10% SEPPB group, while heating loss was 14.4% lower for 5% SEPPB group and 10% SEPPB group when compared to the Control group. No significant differences were observed in terms of moisture, protein, and crude ash components in chicken breast analyses. However, crude fat was 36.8% higher in the 5% SEPPB group when compared to the Control group (P<0.05). Analyses of fatty acid in chicken breast meat showed that stearic acid was significantly higher in the 10% SEPPB group (P<0.05) and linolenic acid was significantly higher in 5% SEPPB group and 10% SEPPB group in comparison to the Control group (P<0.05). Interleukin-2 (IL-2) in blood serum was 44% higher in the 5% SEPPB group and 36% higher in the 10% SEPPB group (P<0.05). Interleukin-6 (IL-6) was similar in both the Control and the 5% SEPPB group, but it was 62% higher in the 10% SEPPB group in comparison to the Control group (P<0.05). Analyses of serum chemical values revealed that albumin was the highest in the 5% SEPPB group, followed by the Control group and then 10% SEPPB group.

The fibroblast in the periodontal ligaments received various stress. Among them, compression and tension are quite important and they are related to the remodeling of tooth and alveolar bone. We studied the change of expression of interleukin-6 (IL-6) and interleukin-8 (IL-8) in the fibroblasts of the periodontal ligaments by real-time RT-PCR and ELISA. In results, the relative activity of IL-6 mRNA in 2 hours after was 1.54${\pm}$0.08 and 1.00${\pm}$0.05 in control and test, respectively (P<0.05). Its 12 hours after was 1.23${\pm}$0.06 and 2.78${\pm}$0.14 in control and test, respectively (P<0.05). The relative activity of IL-8 mRNA in 2 hours after was 1.00${\pm}$0.05 and 0.24${\pm}$0.01 in control and test, respectively (P<0.05). Its 12 hours after was 1.23${\pm}$0.06 and 0.63${\pm}$0.03 in control and test, respectively (P<0.05). The concentration of IL-6 was 1.02${\pm}$0.16 ng/ml, 0.90${\pm}$0.14 ng/ml, and 1.32${\pm}$0.12 ng/ml (P<0.05) in control, 2, and 12 hours after, respectively. The concentration of IL-8 was 2.26${\pm}$0.17 ng/ml, 1.70${\pm}$0.26 ng/ml (P<0.05), and 0.84${\pm}$0.47 ng/ml (P<0.05) in control, 2, and 12 hours after, respectively. In conclusion, the expression of IL-6 was significantly increased after the application of the static compressive force, but IL-8 was significantly decreased. Considering their known function, their expression is quite important in tooth and bone resorption.

Objective: The purpose of this study was to evaluate on the antimicrobial effect on the periodontal pathogens and anti-inflammatory effect of Eriobotryae folium. Eriobotryae folium are constituent herbs of Gagamgamroum, which has been used for a long time in oriental medicine as a herbal medicine for treating halitosis and toothache. Method: Eriobotryae folium was prepared by extracting medicinal herb with water. We investigated antimicrobial activity by the minimum inhibitory concentration (MIC) test. We also investigated inhibition of $IL-1{\beta}-induced$ collagenase (mmp-1), stromelysin-1 (mmp-3), interleukin-6 gene expression in human gingival fibroblasts using RTPCR analysis. Result: The antimicrobial effects of Eriobotryae folium was evaluated with MIC against periodontopathogens; Porphyromonas gingivalis 2561, W50, A7A1-28, 9-14K-1, Prevotella intermedia 28, and Actinobacillus actinomycetemcomitans Y4. MICs of Eriobotryae folium were 1.25 mg/ml, 2.5 mg/ml, 0.625 mg/ml, 1.25 mg/ml, 10 mg/ml and 10 mg/ml. The anti-inflammatory effect of Eriobotryae folium was evaluated with influence of herbs on the $IL-1{\beta}-induced$ expression of mmp-1, mmp-3, and interleukin-6. $IL-1{\beta}$ increased mmp-1, mmp-3, and interleukin-6 mRNA levels. Eriobotryae folium significantly inhibited $IL-1{\beta}-induced$ mmp-1, mmp-3, and interleukin-6 gene expressions in a dose-dependent manner. Conclusion: These results suggested that Eriobotryae folium might reduce the excessive proteolytic capacity of the gingival fibroblast during inflammation and could be developed as a new drug for periodontitis.
