Subcutaneous and visceral adipose tissues show a different risk effect on metabolic disorders because they have distinct cellular properties. We isolated stem cells from the separate human adipose tissues to investigate that subcutaneous and visceral fat depots have metabolic differences. Adipose-derived stem cells (ASCs) were characterized by immunophenotype and differentiation potentials into adipogenic, osteogenic, and chondrogenic lineages. Although subcutaneous and visceral ASCs (S-ASC and V-ASC) express same surface markers (CD31(-) , CD34(-) , CD45(-) , CD73(+) , CD90(+) , and CD105(+) ) and have differentiation potentials, S-ASCs had higher capacity to proliferate and to differentiate into adipogenic lineage than V-ASCs...

Follistatin-like protein 1 (FSTL1) is a newly characterized protein that can regulate the immune response in various ways. Dendritic cells (DCs) are central to immune regulation. In this study, we explored the impact of FSTL1 on DC activity in nasopharyngeal carcinoma (NPC) patients. The surface expression of CD40, CD86, and HLA-DR on DCs was analyzed and showed significantly elevated expression levels, indicating DC maturity. After FSTL1 was added to DCs collected from NPC patients (n = 50), controls (n = 47), and healthy donors (n = 10), interferon γ secretion and T-cell receptor expression in cytotoxic T lymphocytes were also investigated...

ZAK (sterile alpha motif and leucine zipper containing kinase AZK), a serine/threonine kinase with multiple biochemical functions, has been associated with various cell processes, including cell proliferation, cell differentiation, and cardiac hypertrophy. In our previous reports, we found that the activation of ZAKα signaling was critical for cardiac hypertrophy. In this study, we show that the expression of ZAKα activated apoptosis through both a FAS-dependent pathway and a mitochondria-dependent pathway by subsequently inducing caspase-3...

Hypoxia-inducible factors (HIFs) have been shown to be upregulated in tumor tissues and linked with tumor progression and metastasis in breast cancer. Among regulatory mechanisms for HIF expression is a natural occurring antisense named aHIF, which has been shown to be overexpressed in breast cancer and influence the level of the HIF-1α transcript. In the present study, we analyzed the expression of HIF-1α and aHIF in breast cancer tissues versus adjacent noncancer tissues (ANCTs) in relation with the clinical and biological behavior of the tumors...

: The goal of the study was to estimate the effect of a selective V-type H(+) -ATPase inhibitor bafilomycin A1 and nicotinic acid adenine dinucleotide phosphate (NAADP) on energetic processes in NK/Ly cell by directly measuring the respiration of isolated mitochondria and ATPase activities. NAADP (7 μM) increased the activity of Na(+) /K(+) -ATPase in the postmitochondrial fraction of NK/Ly cells, but lower concentration of NAADP decreased it (0.1 and 1 μM). The increase the activity of plasma membrane Ca(2)(+) ATPase (PMCA) under NAADP application (1 and 7 μM) was observed...

Ischemia-reperfusion (I/R) injury often occurs during skin flap transplantation and results in tissue damage. Although estrogen treatment significantly alleviates this I/R injury-induced damage, the detailed molecular mechanism is not clear. In this study, a superficial epigastric artery flap I/R injury model was created in adult Wistar rats. Severe necrosis was observed in skin tissue after I/R injury. Histological examination of skin tissue revealed that I/R injury damages skin structure and results in neutrophil infiltration...

In the present study, we applied a highly sensitive NanoLuc-based technology to understand the status of superoxide dismutase 1 (SOD1) within mammalian cells. Two fragments of NanoLuc (NanoBit), large N-terminal and small C-terminal regions, were fused with wild-type (wt) and mutant human SOD1 (hSOD1) genes and transfected into cells. Luciferase activity through NanoBit assembly was only detected in NanoBit-tagged wtSOD1-expressing cells. Furthermore, the developed NanoLuc system was used to investigate the role of protein-protein interactions in the pathogenesis of amyotrophic lateral sclerosis (ALS)...

CYLD is a deubiquitinating enzyme that exerts a tumor suppressive function. Its downregulation or inactivation has been associated with the development of several types of malignancies including hepatocellular carcinoma (HCC). HCC cells display significantly lower Cyld expression compared to primary human hepatocytes, and Cyld downregulation can contribute to apoptotic resistance of HCC cells. Little is known about the mechanism of Cyld downregulation in human HCC cells. In the present study we explored the possible regulation of Cyld expression by histone deacetylases (HDACs) in human HCC cell lines...

High glucose consumption and lactate synthesis in aerobic glycolysis are a hallmark of cancer cells. They can form lactate also in glutaminolysis, but it is not clear how oxygen availability affects this process. We studied lactate synthesis at various oxygen levels in human primary (SW480) and metastatic (SW620) colon cancer cells cultured with L-Ser and/or L-Asp. Glucose and lactate levels were determined colorimetrically, amino acids by HPLC, expression of AST1-mRNA and AST2-mRNA by RT-PCR. In both lines glucose consumption and lactate synthesis were higher at 10% than at 1% oxygen, and lactate/glucose ratio was increased above 2...

: Myosin light chain kinase (MLCK) phosphorylates S19 of the myosin regulatory light chain (RLC), which is required to activate myosin's ATPase activity and contraction. Smooth muscles are known to display plasticity in response to factors such as inflammation, developmental stage, or stress, which lead to differential expression of nonmuscle and smooth muscle isoforms. Here, we compare steady-state kinetics parameters for phosphorylation of different MLCK substrates: (1) nonmuscle RLC, (2) smooth muscle RLC, and heavy meromyosin subfragments of (3) nonmuscle myosin IIB, and (4) smooth muscle myosin II...

OBJECTIVE: Studies indicate that bupivacaine-induced neurotoxicity results from apoptosis. Gangliosides have been shown to promote neuronal repair and recovery of neurological function after spinal cord injury. Previously, we confirmed that in vivo administration of the ganglioside GM-1 attenuated bupivacaine-induced neurotoxicity in various animal models; however, the underlying mechanism remains unclear. METHODS: Cells of the neuroblastoma line N2a (Neuro2a cells) were divided into three experimental groups: control, bupivacaine-treated, and bupivacaine-treated with GM-1 pretreatment...
