Abstract
Inflammation is a complex biological process which alters the normal physiological function of the immune system resulting in an abnormal microenvironment that leads to several clinical complications. The process of inflammation is mediated through various intracellular signaling factors inside the cells. Apoptosis signal-regulating kinase 1 (ASK1) is an inflammation-derived kinase that controls the activation of other family of kinases such as p38 mitogen-activated protein kinases (p38 MAPKs), which mediates various the inflammatory processes. In this study, we cultured THP-1 macrophage cells to undergo inflammatory proliferation with LPS (1 μg/ml) and TNFα (10 ng/ml) stimulation. Initial in silico analysis was utilized to predict novel microRNAs (miRNAs) that target ASK1 signaling and its expression levels in LPS and TNFα stimulated THP-1 cells were estimated. Among the miRNAs, miR-532-3p showcased the highest binding affinity towards ASK1 kinase. We witnessed that transient transfection of miR-532-3p diminished the levels of ASK1 and downstream phosphorylation/translocation of p38 MAPK. Furthermore, direct targeting of ASK1 resulted in regulation of uncontrolled release of cytokines (TNFα, IL-6, and IL-23) and chemokines (GM-CSF and MIP-2α). Overall, we suggest that miR-532-3p attenuates the pro-inflammatory nature of macrophages by targeting ASK1/p38 MAPK signaling pathway and can be used as a molecular intervention for treating inflammatory diseases.

Abstract
This study is to determine the role and mechanism of cryptotanshinone (CTS) in allergic airway inflammation. Asthma induced by OVA was established in BALB/c mice. We found increased airway hyperresponsiveness (AHR), increased inflammatory cell infiltration, elevated levels of TNF-α, interleukin-1β (IL-1β), IL-4, IL-5, IL-6 and IL-13, decreased interferon gamma (IFN-γ) in lung tissue, increased content of total immunoglobulin E (IgE), OVA specific IgE, Eotaxin, ICAM-1, VCAM-1, nuclear factor-kappaB (NF-κB) and phosphorylation of p38 MAPK in lung tissue. However, the administration of CTS significantly decreased AHR in asthmatic mice, reduced inflammation around the bronchioles and inflammatory cells around airway, regulated cytokine production, reduced the total IgE and OVA-specific IgE levels, and inhibited NF-κB activation and p38 MAPK phosphorylation. In vitro experiments in 16 HBE cells revealed that CTS attenuated CAM-1 and IL-6 expression. These results indicate that CTS alleviates allergic airway inflammation by modulating p38 MAPK phosphorylation and NF-κB activation.

Abstract
Parkinson's disease (PD) is a neurodegenerative disorder caused by insufficient dopamine production due to the loss of 50% to 70% of dopaminergic neurons. A shortage of dopamine, which is predominantly produced by the dopaminergic neurons within the substantia nigra, causes clinical symptoms such as reduction of muscle mass, impaired body balance, akinesia, bradykinesia, tremors, postural instability, etc. Lastly, this can lead to a total loss of physical movement and death. Since no cure for PD has been developed up to now, researchers using cell cultures and animal models focus their work on searching for potential therapeutic targets in order to develop effective treatments. In recent years, genetic studies have prominently advocated for the role of improper protein phosphorylation caused by a dysfunction in kinases and/or phosphatases as an important player in progression and pathogenesis of PD. Thus, in this review, we focus on the role of selected MAP kinases such as JNKs, ERK1/2, and p38 MAP kinases in PD pathology.

Abstract
P38 mitogen-activated protein kinases (MAPKs) are one of the most important central regulatory proteins response to extra environmental stresses. In this study, two novel p38 MAPKs, Ec-P38γ and Ec-P38δ, were identified from Epinephelus coioides, an economically important cultured fish in China and Southeast Asian counties. Both of Ec-p38γ and Ec-p38δ sequences contain a serine/threonine protein kinase (S_TKc) domain and a highly conserved Thr-Gly-Tyr (TGY) motif. Analysis of phylogenetic relationships illustrated that p38 amino acid sequences were conserved between different species indicating that the functions may be similar. The four subtypes of p38 (α, β, γ, and δ) mRNA can be detected in all thirteen tissues examined, but the expression level is different in these tissues. The expression patterns of the four Ec-p38 subtypes in E. coioides were also detected response to Cryptocaryon irritans infection, one of the most important protozoan pathogens of marine fish. The expression of four p38 subtypes was up-regulated in the tissues examined, with the highest expressions of Ec-p38α (5.2 times) and Ec-p38δ (4.2 times) occurring in the skin, while Ec-p38β (24.8 times) and γ (16.6 times) occurred in the spleen. There was no significantly correlation between the expression of Ec-p38γ/Ec-p38δ and the expression of nuclear factor kappaB (NF-kB). The results indicated the sequences and the characters of Ec-p38γ and Ec-p38δ were conserved, the p38 subtypes showed tissue-specific expression patterns in healthy grouper, and their expressions were significantly up-regulated post C. irritans infection, suggesting these p38 MAPKs may play important roles in these tissues during pathogen-caused inflammation.

Abstract
Our understanding of the genetic and non-genetic molecular alterations associated with colorectal cancer (CRC) progression and therapy resistance has markedly expanded in the recent years. In addition to their effects on tumor biology, targeted therapies can have effects on host immune responses. However, the mechanisms by which immune cells organize tumor microenvironments to regulate T-cell activity need to be comprehensively defined. There is good evidence in the literature that alterations in different members of the MAPK superfamily (mainly ERKs and p38 MAPKs) modify the inflammatory response and antitumor immunity, enhancing metastatic features of the tumors. In addition, a plethora of alterations that emerge at relapse often converge on the activation of MAPKs, particularly, ERKs, which act in concert with other oncogenic signals to modulate cellular homeostasis and clonal evolution during targeted therapies. Herein, we discuss how this knowledge can be translated into drug development strategies aimed at increasing tumor antigenicity and antitumor immune responses. Insights from these studies could provide a framework for considering additional combinations of targeted therapies and immunotherapies for the treatment of CRC.

Abstract
Formation of skeletal muscle fibers (myogenesis) during development and after tissue injury in the adult constitutes an excellent paradigm to investigate the mechanisms whereby environmental cues control gene expression programs in muscle stem cells (satellite cells) by acting on transcriptional and epigenetic effectors. Here we will review the molecular mechanisms implicated in the transition of satellite cells throughout the distinct myogenic stages (i.e., activation from quiescence, proliferation, differentiation, and self-renewal). We will also discuss recent findings on the causes underlying satellite cell functional decline with aging. In particular, our review will focus on the epigenetic changes underlying fate decisions and on how the p38 MAPK signaling pathway integrates the environmental signals at the chromatin to build up satellite cell adaptive responses during the process of muscle regeneration, and how these responses are altered in aging. A better comprehension of the signaling pathways connecting external and intrinsic factors will illuminate the path for improving muscle regeneration in the aged.

Abstract
AIM: To investigate the possible mechanism underlying the preventive effect of exogenous carbon monoxide (CO) on multiple organ injury induced by intestinal ischemia-reperfusion (IIR) in rats.
METHODS: Sixty-four male Wistar rats were randomly and equally allocated into eight groups. IIR was induced in rats by clamping the superior mesenteric artery (SMA) for 60 min and reperfusing for 120 min. Group A and sham operation did not undergo SMA clamping. Group B underwent SMA clamping for 60 min and reperfusing for 120 min. Groups C1/C2, D1/D2, and E1/E2 inhaled 100 and 250 µL/L CO 10, 60 min before SMA clamping and 60 min after reperfusion, respectively. The expression of p38 mitogen-activated protein kinases (MAPKs) in different tissues was detected by Western blot.
RESULTS: Compared to Group A, the expression of p38 MAPKs in the intestine, lung and liver increased in Group B, but the differences were not significant (0.468 ± 0.213 vs 0.474 ± 0.151; 0.439 ± 0.111 vs 0.482 ± 0.103; 0.622 ± 0.112 vs 0.654 ± 0.016, all P > 0.05). Compared to Group B, a marked increase in p38 MAPKs expression in the intestine, lung and liver was detected in Groups C1/C2, D1/D2, and E1/E2 (1.540 ± 0.346, 1.626 ± 0.277, 1.36 5± 0.233, 1.483 ± 0.265, 1.353 ± 0.234, 1.372 ± 0.2731 vs 0.474 ± 0.151; 1.654 ± 0.211, 1.701 ± 0.101, 1.398 ± 0.245, 1.444 ± 0.272, 1.288 ± 0.218, 1.366 ± 0.244 vs 0.482 ± 0.103; 1.695 ± 0.234, 1.723 ± 0.213, 1.423 ± 0.221, 1.586 ± 0.254, 1.322 ± 0.261, 1.411 ± 0.296 vs 0.654 ± 0.016, all P < 0.05).
CONCLUSION: Exogenous CO provides protection against IIR-induced multiple organ injury possibly by modulating the expression of p38 MAPKs in rats.
