Abstract
Pancreatic cancer is a kind of aggressive tumor famous for its lethality and intractability, and pancreatic ductal adenocarcinoma is the most common type. Patients with pancreatic cancer often suffer a rapid loss of weight and abdominal neuropathic pain in their early stages and then go through cachexia in the advanced stage. These features of patients are considered to be related to metabolic reprogramming of pancreatic cancer and abundant nerve innervation responsible for the pain. With increasing literature certifying the relationship between nerves and pancreatic ductal adenocarcinoma (PDAC), more evidence point out that innervation's role is not limited to neuropathic pain but explore its anti/pro-tumor functions in PDAC, especially the neural-metabolic crosstalks. This review aims to unite pancreatic cancer's innervation and metabolic rearrangements with terminated published articles. Hopefully, this article could explore the pathogenesis of PDAC and further promote promising detecting or therapeutic measurements for PDAC according to the lavish innervation in PDAC.

Abstract
Wogonin (5,7-dihydroxy-8-methoxyflavone) is an active flavonoid compound originally isolated from Scutellaria radix, which has been used to treat lung inflammation in Korea, China, and Japan. Wogonin has been known to inhibit inducible nitric oxide synthase and have the anti-tumor properties. However, the effects of wogonin on virus-induced macrophages are not fully reported. In this study, the anti-inflammatory effect of wogonin on double-stranded RNA (dsRNA)-induced macrophages was examined. Wogonin restored the cell viability in dsRNA [polyinosinic-polycytidylic acid]-induced RAW 264.7 mouse macrophages at concentrations of up to 50 μM. Wogonin significantly inhibited the production of nitric oxide, IL-1α, IL-1β, IL-6, IL-10, IP-10, G-CSF, GM-CSF, LIF (IL-6 class cytokine), LIX/CXCL5, MCP-1, M-CSF, MIP-1α, MIP-1β, MIP-2, RANTES/CCL5, TNF-α, and VEGF as well as calcium release and mRNA expression of signal transducer and activated transcription 1 (STAT1) and STAT3 in dsRNA-induced RAW 264.7 cells (P < 0.05). In conclusion, wogonin has anti-inflammatory properties related with its inhibition of nitric oxide, cytokines, chemokines, and growth factors in dsRNA-induced macrophages via the calcium-STAT pathway.

Abstract
The tachykinins, exemplified by substance P, are one of the most intensively studied neuropeptide families. They comprise a series of structurally related peptides that derive from alternate processing of three Tac genes and are expressed throughout the nervous and immune systems. Tachykinins interact with three neurokinin G protein-coupled receptors. The signaling, trafficking, and regulation of neurokinin receptors have also been topics of intense study. Tachykinins participate in important physiological processes in the nervous, immune, gastrointestinal, respiratory, urogenital, and dermal systems, including inflammation, nociception, smooth muscle contractility, epithelial secretion, and proliferation. They contribute to multiple diseases processes, including acute and chronic inflammation and pain, fibrosis, affective and addictive disorders, functional disorders of the intestine and urinary bladder, infection, and cancer. Neurokinin receptor antagonists are selective, potent, and show efficacy in models of disease. In clinical trials there is a singular success: neurokinin 1 receptor antagonists to treat nausea and vomiting. New information about the involvement of tachykinins in infection, fibrosis, and pruritus justifies further trials. A deeper understanding of disease mechanisms is required for the development of more predictive experimental models, and for the design and interpretation of clinical trials. Knowledge of neurokinin receptor structure, and the development of targeting strategies to disrupt disease-relevant subcellular signaling of neurokinin receptors, may refine the next generation of neurokinin receptor antagonists.

Abstract
Leukaemia inhibitory factor (LIF) is one of the cytokines that is indispensable for embryo implantation. The aim of the present study was to investigate the role of activation of extracellular signal-regulated kinase (ERK) 1/2 in LIF-mediated proliferation of HTR-8/SVneo cells. Stimulation of HTR-8/SVneo cells with LIF (50 ng mL(-1)) resulted in an increase in cell proliferation (P < 0.05) via increased transition of cells to the G(2)/M phase of cell cycle. Stimulation with LIF resulted in the activation of both signal transducer and activator of transcription (STAT) 3 Tyr(705) and ERK1/2, but inhibition of ERK1/2 signalling by pretreatment of cells with U0126 (10 µM) for 2h resulted in abrogation of LIF-mediated increases in G(2)/M transition, with a significant decrease (P < 0.05) in absolute cell numbers compared with control. Although STAT3 silencing had no effect on LIF-dependent proliferation of HTR-8/SVneo cells, it did result in an increase in cell apoptosis, which increased further upon inhibition of ERK1/2 activation irrespective of LIF stimulation. Stimulation of cells with LIF increased the Bcl-2/Bax ratio, whereas ERK1/2 inhibition decreased the Bcl-2/Bax ratio, even after LIF stimulation. Hence, it can be inferred that ERK1/2 activation is essential for LIF-mediated increases in proliferation and that both STAT3 and ERK1/2 activation are important for the survival of HTR-8/SVneo cells.

Abstract
BACKGROUND Asthma, one major respiratory consequence, might be caused by a complex interaction between multiple candidate genes and environmental factors. Herein, we aimed to investigate whether Janus kinase (JAK)-1 gene polymorphisms are associated with asthma susceptibility. MATERIALS AND METHODS Patients were divided into two groups: (1) asthma (n=117) and (2) nonasthma (n=60). The JAK-1 polymorphisms (rs2780895, rs10789166, rs4916008, rs2780885, rs17127114, and rs3806277) were amplified by polymerase chain reaction and detected by electrophoresis after restriction enzyme (HpyCH4IV, Tsp45I, HpaII, XmnI, MspI, and HpaII) digestions. Genotypes, allelic frequencies, and association of haplotypes in both groups were compared. RESULTS JAK-1 rs2780895 gene polymorphism is associated with susceptibility to asthma. Distributions of JAK-1 rs2780895*CC/CT/TT and C/T allele in both groups are: (1) 80/4/16% and 82/18%; (2) 48/45/7% and 71/29%. Other 5 JAK-1 SNPs (rs10789166, rs4916008, rs2780885, rs17127114, and rs3806277) are not associated with asthma susceptibilities. Distributions of JAK-1 rs10789166*AA/AG/GG, rs4916008*CC/CT/TT, rs2780885*CC/CT/TT, rs17127114*AA/AG/GG, rs3806277*AA/AG/GG in both groups are: (1) 50/40/10%, 42/49/9%, 50/40/10%, 9/37/54%, 8/35/57%; (2) 43/50/7%, 40/50/10%, 50/43/7%, 7/48/45%, 6/42/52%. Haplotype analyses for JAK-1 gene polymorphisms (rs2780895-rs10789166-rs4916008-rs2780885-rs17127114-rs3806277) revealed that JAK-1 haplotypes are not associated with asthma susceptibilities. CONCLUSIONS JAK-1 rs2780895 C-related genotype and allele are associated with higher susceptibility to asthma. JAK-1 rs10789166, rs4916008, rs2780885, rs17127114, and rs3806277 single-nucleotide polymorphisms are not associated with asthma development. Some JAK-related genetic variations might be associated with asthma pathogenesis, which deserve further surveys.

Abstract
Neurokinin 1 receptors (NK1Rs) in alveolar macrophages (AMs) are overexpressed by cigarette smoke (CS) in vivo and substance P (SP) in vitro. Because CS could stimulate pulmonary C-fibers (PCFs) to release SP, we asked whether this neurogenic SP was responsible for AMs' NK1R overexpression during CS. We compared pulmonary SP and AMs' NK1R gene and protein levels in intact and PCF-degenerated mice exposed to filtered air (FA) and CS. Pulmonary SP was increased by CS but almost eliminated by PCF degeneration, which closely correlated to the changes in AMs' NK1R expression. Moreover, SP was higher in the PCF-degenerated mice exposed to CS than FA. To evaluate the direct effects of CS and SP on the NK1R expression and the involvement of nuclear factor (NF)-kappaB, macrophages were exposed to CS condensate (CSC) and/or SP without or with blocking NK1R or inhibiting NF-kappaB activation in vitro. CSC itself induced a moderate secretion of SP from macrophages, and amplified NK1R responses to SP that were completely eliminated by blocking NK1R, and substantially reduced after inhibiting NF-kappaB. Our results suggest that CS produces AMs' NK1R overexpression primarily by both promoting neurogenic SP release and synergizing NK1R response to neurogenic SP largely via activating NF-kappaB pathway.

Abstract
Cytokines are upregulated in a variety of inflammatory conditions and cytokine/receptor interactions can activate JAK-STAT signaling. Previous studies demonstrated upregulation of numerous cytokines in the urinary bladder following cyclophosphamide (CYP)-induced cystitis. The role of JAK-STAT signaling in urinary bladder inflammation and referred somatic sensitivity has not been addressed. The contribution of JAK-STAT signaling pathways in CYP-induced bladder hyperreflexia and referred somatic hypersensitivity was determined in CYP-treated rats using a JAK2 inhibitor, AG490. Acute (4 h; 150 mg/kg ip), intermediate (48 h; 150 mg/kg ip), or chronic (75 mg/kg ip, once every 3 days for 10 days) cystitis was induced in adult, female Wistar rats with CYP treatment. Phosphorylation status of STAT-3 was increased in urinary bladder after CYP-induced cystitis (4 h, 48 h, chronic). Blockade of JAK2 with AG490 (5-15 mg/kg ip or intravesical) significantly (P < or = 0.05) reduced bladder hyperreflexia and hind paw sensitivity in CYP-treated rats. These studies demonstrate a potential role for JAK-STAT signaling pathways in bladder hyperreflexia and referred pain induced by CYP-induced bladder inflammation.

Abstract
BACKGROUND Secretory leukocyte proteinase inhibitor (SLPI) is an important antileukoprotease in airway. The aim of the present study was to explore the expression of SLPI in the bronchi and lung tissues of chronic obstructive pulmonary disease (COPD) models and the regulative mechanism by transforming growth factor (TGF)beta(1)/Smads signal pathway in bronchial epithelial cell. METHODS COPD rat model was established and was treated with or without TGFbeta1 monoclonal antibody. Spirometry was conducted, and expressions of TGFbeta(1), Smad4 and SLPI were examined by immunohistochemistry and reverse-transcription polymerase chain reaction (RT-PCR), respectively. The normal human bronchial epithelial cell (NHBE) was cultured, preincubated with or without siRNA (Smad4), and then stimulated with TGFbeta(1). Expressions of Smad4 and SLPI were detected by immunocytochemistry, Western blot and RT-PCR, respectively. RESULTS As compared with the model group, after treatment with TGFbeta(1) monoclonal antibody, peak expiratory flow (PEF), forced expiratory volume in 0.3 sec (FEV(0.3)) and FEV(0.3)/forced vital capacity (FVC) in the TGFbeta(1) monoclonal antibody intervention group were all significantly improved. Expression of SLPI was also improved, but expression of Smad4 was significantly decreased. Expression of SLPI in NHBE cells was inhibited by TGFbeta(1) both at the mRNA level and the protein level. Furthermore, effect of TGFbeta(1)-inhibited expression of SLPI in NHBE cells was disengaged by siRNA (Smad4) both at the mRNA level and the protein level. CONCLUSIONS Decreased expression of SLPI in the COPD rat model may be mainly caused by the increased expression of TGFbeta(1), and this process is probably related to the activation of Smads signal pathway.
