Streptococcus pneumoniae induced c-Jun-N-terminal kinase- and AP-1 -dependent IL-8 release by lung epithelial BEAS-2B cells

open access: yesRespiratory Research, 2006
Background Although pneumococcal pneumonia is one of the most common causes of death due to infectious diseases, little is known about pneumococci-lung cell interaction. Herein we tested the hypothesis that pneumococci activated pulmonary epithelial cell

Hepatocyte CBX2 Safeguards Hepatic Lipid Homeostasis by Elevating Ca2+‐CaMKK2‐AMPK Signaling to Counter MASLD

open access: yesAdvanced Science, EarlyView.
In hepatocytes, CBX2 promotes H3K4me3 enrichment at the Orai1 promoter to enhance Orai1 transcriptional activation, thereby increasing intracellular Ca2+ levels. The elevated Ca2+ activates the CaMKK2‐AMPK signaling cascade, resulting in ACC phosphorylation and downstream metabolic regulation. This cascade suppresses de novo lipogenesis (Fasn, Acc, Scd‐

磷酸化JNK在小鼠腹水型肝癌高、低淋巴道转移株中表达的研究

open access: yesZhongguo shiyan zhenduanxue, 2008
目的观察磷酸化JNK(p-JNK)在小鼠腹水型肝癌高、低淋巴道转移株(Hca-F、Hca-P)中的表达水平,分析其在这两个细胞株中表达的关系及意义,以进一步探讨JNK基因在肝癌淋巴道转移过程中的作用。方法以小鼠腹水型肝癌淋巴道高转移株(Hca-F)和低转移株(Hca-P)为研究对象,采用Western Blot检测p-JNK在Hca-F和Hca-P两细胞株的表达。结果p-JNK在Hca-F细胞株中的表达显著高于Hca-P,二者间差异有显著性 ...

P38 and JNK Mitogen-Activated Protein Kinases Interact With Chikungunya Virus Non-structural Protein-2 and Regulate TNF Induction During Viral Infection in Macrophages

open access: yesFrontiers in Immunology, 2019
Chikungunya virus (CHIKV), a mosquito-borne Alphavirus, is endemic in different parts of the globe. The host macrophages are identified as the major cellular reservoirs of CHIKV during infection and this virus triggers robust TNF production in the host ...

Effect of JNK inhibitor on release of KC, JNK activity and intramacrophagic parasite growth.

open access: yes, 2014
(A) Resident macrophages were infected or not with L. major in the presence of solvent or the indicated MAPK inhibitors. The levels of KC were determined by ELISA after 20 h of infection. (B) Macrophages were infected or not in the presence of solvent or

A UBE3A‐UTX Proteostasis‐Epigenetic Axis Governs Hypothalamic Energy Homeostasis

open access: yesAdvanced Science, EarlyView.
Ubiquitin protein ligase E3A (UBE3A) regulates hypothalamic energy homeostasis and promotes degradation of the histone demethylase UTX (KDM6A). Neuronal UBE3A loss increases susceptibility to diet‐induced obesity and is accompanied by UTX accumulation, reduced histone H3 lysine 27 trimethylation, and altered endoplasmic reticulum stress‐responsive gene

Cucurbitacin-I (JSI-124) activates the JNK/c-Jun signaling pathway independent of apoptosis and cell cycle arrest in B Leukemic Cells

open access: yesBMC Cancer, 2011
Background Cucurbitacin-I (JSI-124) is potent inhibitor of JAK/STAT3 signaling pathway and has anti-tumor activity in a variety of cancer including B cell leukemia.

Knockdown of S1PR2 attenuated S1PR2, p-PI3K, p-ERK, p-JNK, p-p38, and p-NF-kBp65 protein expressions in BMMs.

open access: yes, 2016
Murine BMMs were uninfected, infected with a S1PR2 shRNA lentivirus, or infected with a control shRNA lentivirus (moi 50) for 72 h. Then the cells were either unstimulated or stimulated with Aa (1.5 CFU/cell) for 1 to 4 h. (A) S1PR2, p-PI3K, p-ERK, p-JNK,

Poly(I:C)‐Activated Nasal Fibroblasts Promote Eosinophil Recruitment in CRSwNP

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by persistent mucosal inflammation and eosinophilic infiltration. Although epithelial and immune cells have been widely studied, the role of nasal fibroblasts in innate immune activation and eosinophil recruitment remains unclear.
