Abstract
Aberrant Signal transducers and activators of transcription-3 (STAT3) signaling pathway is a major cause of tumor invasion and metastasis; the underlying mechanisms, however, are not well understood. Epithelial-mesenchymal transition (EMT) is an early event that occurs during invasion of cancers of an epithelial origin. It remains elusive whether STAT3signaling pathway is involved in EMT. The objective of this study was to evaluate the effect of blockage of STAT3 signaling pathway on IL-6 inducing EMT in human pancreatic cancer cells. We used SW1990 cells and induced them to undergo EMT by exposing these cells to soluble factor interleukin-6 (IL-6). The expression of Snail, E-cadherin, and Twist was detected by reverse transcription-PCR, real-time PCR, and Western blotting. Cell morphology was observed under invert phase-contrast microscope.The invasion ability was determined by cell invasion assay in vitro. Our results demonstrated that STAT3 signaling pathway was involved in pancreatic cancer cell invasion and EMT, and that EMT induced by IL-6 was associated with the activation of STAT3 signaling pathway. Inhibition of STAT3 signaling pathway by silencing of the STAT3 gene with RNAi blocked STAT3 signaling pathway activation and suppressed EMT in pancreatic cancer cells. Collectively, the STAT3 signaling pathway plays an important role in the process of EMT of pancreatic cancer by regulating Snail gene expression. Better understanding of STAT3 signaling pathways in EMT may contribute to development of novel therapeutic strategies in invasion and metastasis of pancreatic cancer.

Abstract
Muscle injuries are common musculoskeletal problems encountered in sports medicine clinics. In this study, we examined the effect of lentivirus-mediated small interfering RNA (siRNA) targeting Smad4 on the suppression of the fibrosis in injured skeletal muscles. We found that Smad4-siRNA could efficiently knock down the expression of Smad4 in the C2C12 myoblast cells and in the contunded mice gastrocnemius muscle. The expression of mRNA level of Smad4 decreased to 11% and 49% compared to the control group, respectively, and the expression of protein level decreased to 13% and 57% respectively. Moreover, the lentivirus-mediated siRNA was stably transfected only into the skeletal muscle and not into the liver of the animals. In contunded mice gastrocnemius, the collagenous and vimentin-positive area in the Smad4 siRNA group reduced to 36% and 37% compared to the control group, respectively. Furthermore, compared to the scrambled Smad4 siRNA-injected mice and PBS control-injected mice, the muscle function of the mice injected with lentivirus-mediated Smad4 siRNA improved in terms of both fast-twitch and tetanic strength (P<0.05). The results suggest that the gene therapy of inhibiting Smad4 by lentivirus-mediated siRNA could be a useful approach to prevent scar tissue formation and improve the function of injured skeletal muscle.

Abstract
Cardiac fibroblast-myofibroblast transformation (CMT) is a critical event in the initiation of myocardial fibrosis. Notch signaling has been shown to regulate myofibroblast transformation from other kinds of cells. However, whether Notch signaling is also involved in CMT remains unclear. In the present study, expressions of Notch receptors in cardiac fibroblasts (CFs) were examined, effects of Notch signaling inhibitor N-[N-(3,5-difluorophenacetyl)-l-alanyl]-S-phenylglycine t-butyl ester (DAPT) and transforming growth factor-beta1 (TGF-beta1) on CMT were determined by increasing alpha-smooth muscle actin (alpha-SMA) expression and collagen synthesis, and Notch signaling was examined by analyzing expressions of Notch receptors. The results showed that: (1) Notch receptor 1, 2, 3 and 4 were all expressed in CFs; (2) DAPT promoted CMT in a time-dependent manner; (3) During the period of CMT induced by TGF-beta1, expressions of Notch receptor 1, 3 and 4 in CFs were down-regulated, whereas there was no change for Notch receptor 2. Moreover, the downtrends of Notch 1, 3 and 4 were corresponding to the trend growth of alpha-SMA expression and collagen synthesis. These results suggested that inhibiting of Notch signaling might promote CMT. The down-regulations of Notch receptor 1, 3 and 4 induced by TGF-beta1 may facilitate CMT. In conclusion, inhibition of Notch signaling might be a novel mechanism of CMT in myocardial fibrosis.

Abstract
A multi-objective optimization problem can be solved by decomposing it into one or more single objective subproblems in some multi-objective metaheuristic algorithms. Each subproblem corresponds to one weighted aggregation function. For example, MOEA/D is an evolutionary multi-objective optimization (EMO) algorithm that attempts to optimize multiple subproblems simultaneously by evolving a population of solutions. However, the performance of MOEA/D highly depends on the initial setting and diversity of the weight vectors. In this paper, we present an improved version of MOEA/D, called EMOSA, which incorporates an advanced local search technique (simulated annealing) and adapts the search directions (weight vectors) corresponding to various subproblems. In EMOSA, the weight vector of each subproblem is adaptively modified at the lowest temperature in order to diversify the search toward the unexplored parts of the Pareto-optimal front. Our computational results show that EMOSA outperforms six other well established multi-objective metaheuristic algorithms on both the (constrained) multi-objective knapsack problem and the (unconstrained) multi-objective traveling salesman problem. Moreover, the effects of the main algorithmic components and parameter sensitivities on the search performance of EMOSA are experimentally investigated.

Abstract
The expression of the types of tachykinin receptors in the dorsal root ganglion (DRG) neurons by means ofXenopus oocyte expressing system was studied. Poly(A)(+) RNAs were extracted from cat cervical and lumbar DRG. Two days after injection of Poly (A)(+) RNAs, the oocytes were recorded with the two-electrode voltage clamp technique. In the oocytes injected with DRG poly(A)(+) RNA, [Sar(9), Met(O(2))(11)]-substance P(Sar -SP, 1 mumol/L), neurokinin A (NKA, 1 mumol/L) or [beta-Ala(8)]-neurokinin A((4-10)) (Ala-NKA, 1 mumol/L) produced an inward current comprising a rapid spike and a long sustained oscillatory component for several minutes. Sar-SP induced response was blocked by NK-1 antagonist L-668, 169 (1 mumol/L), but not by NK-2 antagonist L-659, 877(1mumol/L). In contrast, Ala-NKA and NKA responses were only blocked by L-659, 877. The oocytes injected with DH Poly(A)(+)RNA also responded to Sar-SP and NKA with similar inward currents, which were selectively blocked by L-668, 169 and L-659, 877, respectively. These tachykinins-induced responses had a potent desensitization. The present data indicate expression of NK-1 and NK-2 receptors in DRG neurons, suggesting that there may be tachykinin autoreceptors on the nociceptive primary afferent terminals.
