Homeodomain-interacting protein kinase 2 (HIPK2) is a serine/threonine kinase involved in transcriptional regulation and apoptosis. Here we demonstrate that HIPK2 regulates transforming growth factor (TGF) beta-induced c-Jun NH(2)-terminal kinase (JNK) activation and apoptosis. HIPK2 colocalizes with Daxx, a protein acting in TGF-beta-induced JNK activation and apoptosis, in promyelocytic leuke...
Signaling pathways control cell fate decisions that ultimately determine the behavior of cancer cells. Therefore, the dynamics of pathway activity may contain prognostically relevant information different from that contained in the static nature of other types of biomarkers. To investigate this hypothesis, we characterized the network that regulated stress signaling by the c-Jun N-terminal kina...
Researches have revealed several stressors, which could activate unfolded protein response (UPR) in cells. However, the survival or death pathway was determined by the duration of UPR exposure. Based on the UPR mediated death pathway, our study was aimed to investigate role of UPR on c-Jun N-terminal kinase (JNK)/activator protein-1 (Ap-1) signal transduction in diindolylmethane (DIM) treated o...
Multidrug resistance-associated protein 1 (MRP1) plays a protective role in the etiology and progression of chronic obstructive pulmonary disease (COPD) which results from oxidative stress and inflammation of lung injury. The lower functional MRP1 activity is related to COPD development. Our previous study showed that Allyl isothiocyanate (AITC) induced the expression and activity of MRP1 in a ...
The non-canonical Wnt/planar cell polarity (Wnt/PCP) pathway plays a crucial role in embryonic development. Recent work has linked defects of this pathway to breast cancer aggressiveness and proposed Wnt/PCP signalling as a therapeutic target. Here we show that the archetypal Wnt/PCP protein VANGL2 is overexpressed in basal breast cancers, associated with poor prognosis and implicated in tumour...
Mechanical forces affect all the tissues of our bodies. Experiments conducted mainly on cultured cells have established that altering these forces influences cell behaviors, including migration, differentiation, apoptosis, and proliferation [1, 2]. The transcriptional coactivator YAP has been identified as a nuclear relay of mechanical signals, but the molecular mechanisms that lead to YAP acti...
We previously reported that hypotonic stress stimulated transepithelial Na(+) transport via a pathway dependent on protein tyrosine kinase (PTK; Niisato N, Van Driessche W, Liu M, Marunaka Y. J Membr Biol 175: 63-77, 2000). However, it is still unknown what type of PTK mediates this stimulation. In the present study, we investigated the role of receptor tyrosine kinase (RTK) in the hypotonic st...
BACKGROUND Endothelial outgrowth cells (EOCs) are terminal endothelial progenitor cells (EPCs). Asymmetric dimethylarginine (ADMA) has been identified as a novel risk factor for cardiovascular diseases. Our aim in the present study was to investigate the effect of regulation of asymmetric dimethylarginine (ADMA) on EOCs apoptosis and to explore the underlining mechanisms of c-Jun N-terminal pro...
The dynamic behavior of the nucleolus plays a role in the detection of and response to DNA damage of cells. Two nucleolar proteins, p14(ARF)/p19(ARF) and B23, were shown to translocate out of the nucleolus after exposure of cells to DNA-damaging agents. This translocation affects multiple cellular functions, such as DNA repair, proliferation, and survival. In this study, we identify a pathway a...
This study aimed to investigate the expression of signaling molecules, such as c‑Jun N‑terminal kinase 1 (JNK1) and insulin receptor substrate 1 (IRS1), in the myocardium of diabetic rats following intervention in the diacylglycerol‑protein kinase C (DAG‑PKC) signal transduction pathway. The rats were divided into three groups, the diabetic model, control and breviscapine‑treated diabetes (inte...
