BACKGROUND INFORMATION STAT3 (signal transducer and activator of transcription 3) is an important transcription factor involved in many biological events, including apoptosis, tumorigenesis, angiogenesis and epithelial-to-mesenchymal transition. However, no direct evidence for a role of STAT3 in 3T3-L1 adipocyte differentiation has been reported. RESULTS(More)
The forkhead box transcription factor A2 (FOXA2) is an important regulator in animal development and body homeostasis. However, whether FOXA2 is involved in transforming growth factor β1 (TGF-β1)-mediated epithelial-to-mesenchymal transition (EMT) and tumor metastasis remains unknown. The present study showed that in human lung cancer cell lines, the(More)
BACKGROUND The electrophysiologic functions of the intrinsic cardiac autonomic nervous system (ANS) are not well understood. OBJECTIVES The purpose of this study was to investigate the functional interactions between ganglionated plexi within the intrinsic cardiac ANS. METHODS The hearts of 21 dogs were exposed via right and/or left thoracotomy to(More)
Apoptosis and epithelial-to-mesenchymal transdifferentiation or transition (EMT) are crucial for normal development and body homeostasis. The alterations of these events are closely related to some pathologic processes, such as tumor formation and metastasis, fibrotic diseases of liver and kidney, and abnormal development of embryos. The mechanism that(More)
Apoptosis is an important cell suicide program which involves the caspases activation and is implicated in physiological and pathological processes. Poly(ADP-ribose) polymerase (PARP) cleavage is often associated with apoptosis and has been served as one hallmark of apoptosis and caspase activation. In this study, we aimed to determine TGF-beta1-induced(More)
The proper function of the bone morphogenic protein (BMP) pathway during embryonic development and organ maintenance requires its communication with other signaling pathways. Unlike the well-documented regulation of the BMP pathway by FGF/MAPK and Wnt/GSK3 signals, cross-talk between BMP/Smad and retinoic acid (RA)/RA receptor (RAR) pathways is poorly(More)
UNLABELLED Epithelial-mesenchymal transition (EMT) has been implicated in embryonic development, fibrosis, and tumor metastasis. Histone deacetylases (HDACs) also play important roles in the control of various physiological and pathological events. However, whether HDACs are involved in the control of EMT in liver cells remains unidentified. Three(More)
Protein kinase C (PKC) is a member of serine/threonine protein kinase family that plays important roles in the control of vast variety of cellular functions. Nevertheless, the regulatory effect of PKC on adipogenesis remained not well understood. In this study, we investigated the effect of several PKC isoforms on the adipogenic conversion of 3T3-L1(More)
Adenosine 3',5'-cyclic monophosphate (cAMP) and transforming growth factor-beta are important regulators of many biological processes. In this study we investigated the effect and its potential mechanism of cAMP on transforming growth factor-beta1- and serum deprivation-induced apoptosis in Mv1Lu cells. Transforming growth factor-beta1 treatment or serum(More)
