REVIEW
Ming-Chuan Hsu, Wen-Chun Hung
Originally identified as a metabolic enzyme that catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to ADP in the glycolytic pathway, pyruvate kinase M2-type (PKM2) has been shown to exhibit novel biological activities in the nucleus and outside the cells. Although cell-based studies reveal new non-canonical functions of PKM2 in gene transcription, epigenetic modulation and cell cycle progression, the importance of these non-canonical functions in PKM2-mediated tumorigenesis is still under debate because studies in genetically modified mice do not consistently echo the findings observed in cultured cancer cells...

In recent years, using genetic engineering and bioengineering techniques, Bifidobacterium as a carrier to express specific functions of the protein or polypeptide, has become a new treatment for disease. Ulcerative colitis (UC) is a type of inflammatory bowel diseases (IBD). Although the cause of this inflammatory disorder is still unknown, a large amount of evidence suggests that ulcerative colitis is associated with increased activity of reactive oxygen species (ROS), manganese superoxide dismutase (MnSOD) is a kind of superoxide dismutase (SOD) has been demonstrated to play a key role in the pathophysiology of colitis...

Individuals higher in dispositional mindfulness, a quality of non-judgmental attention to the present moment, fare better than their less mindful counterparts on a wide range of psychological and interpersonal outcomes. However, remarkably little is known about the potential influence of dispositional mindfulness on sexual outcomes. Here we investigated whether dispositional mindfulness was associated with a range of sexual outcomes, including sexual satisfaction, sexual hyperactivation (heightened sexual desire and worry), sexual deactivation (suppression of sexual desire and behavior), and problematic pornography use...

The efficacy of stem cell-based bone tissue engineering has been hampered by cell death and limited fate control. A smart cell culture system with the capability of sequentially delivering multiple factors in specific growth stages, like the mechanism of the natural extracellular matrix modulating tissue formation, is attractive for enhancing cell activity and controlling cell fate. Here, a bone forming peptide-1 (BFP-1)-laden mesoporous silica nanoparticles (pep@MSNs) incorporated adhesion peptide, containing the arginine-glycine-aspartic acid (RGD) domain, modified alginate hydrogel (RA) system (pep@MSNs-RA) was developed to promote the activity and stimulate osteo-differentiation of human mesenchymal stem cells (hMSCs) in sequence...

Density Functional Theory (DFT) is a successful and well-established theory for the study of the structure of simple and complex fluids at equilibrium. The theory has been generalized to dynamical situations when the underlying dynamics is diffusive as in, for example, colloidal systems. However, there is no such a clear foundation for Dynamic DFT (DDFT) for the case of simple fluids in contact with solid walls. In this work, we derive DDFT for simple fluids by including not only the mass density field but also the momentum density field of the fluid...

Terror management theory outlines how humans seek self-esteem and worldview validation to manage death-related anxiety. Accumulating evidence reveals that close relationships serve a similar role. However, to date, there has been no synthesis of the literature that delineates when close relationships buffer mortality concerns, under what conditions, on which specific outcomes, and for whom. This systematic review presents over two decades of research to address these questions. Findings from 73 reviewed studies revealed that close relationships serve an important role in buffering death-related anxiety...

We compared hepatic and serum lipid changes in hepatocellular carcinoma (HCC) patients to have a better understanding of the molecular pathogenesis of this disease and discovery novel lipid biomarkers. Hepatic and serum lipid profiling was conducted in paired liver and serum samples from 50 HCC patients and 24 healthy controls. A total of 20 hepatic and 40 serum lipid signatures were identified, yet there was hardly any significant correlation between them. The results indicated that triglycerides and phosphatidylcholines contributed significantly to altered hepatic lipids, whereas triglycerides and phosphatidylethanolamine-based plasmalogens (PEp) contributed most to altered serum lipids...

BACKGROUND: Previous pancreatitis is a definite patient-related risk factor for pancreatitis after endoscopic retrograde cholangiopancreatography (post-ERCP pancreatitis: PEP). However, the effects of differences in the history of PEP and acute pancreatitis on the occurrence of PEP have not been fully investigated. We examined the relationship between previous PEP or previous acute pancreatitis and procedural factors associated with PEP. METHODS: Clinical data on 1,334 consecutive patients undergoing ERCP between April 2006 and June 2010 were collected...

Aspergillus flavus is among the most devastating opportunistic pathogens of several food crops including rice, due to its high production of carcinogenic aflatoxins. The presence of these organisms in economically important rice strip farming is a serious food safety concern. Several polymerase chain reaction (PCR) primers have been designed to detect this species; however, a comparative assessment of their accuracy has not been conducted. This study aims to identify the optimal diagnostic PCR primers for the identification of A...

Public awareness of domestic waste characteristics and management (PADWCM) is a prerequisite for a domestic waste management (DWM) plan. In this study, we considered China as a typical example of developing countries to investigate the public perception of environmental pollution (PEP), PADWCM, and its socioeconomic factors using questionnaires and statistical methods. The results indicated that the public PEP was mainly due to obvious environmental contamination in local villages and the PADWCM is still inadequate in rural areas...

For nearly 30 years, coenzyme M (CoM) was assumed to be present solely in methanogenic archaea. In the late 1990s, CoM was reported to play a role in bacterial propene metabolism, but no biosynthetic pathway for CoM has yet been identified in bacteria. Here, using bioinformatics and proteomic approaches in the metabolically versatile bacterium Xanthobacter autotrophicus Py2, we identified four putative CoM biosynthetic enzymes encoded by xcbB1, C1, D1, and E1 genes. Only XcbB1 was homologous to a known CoM biosynthetic enzyme (ComA), indicating that CoM biosynthesis in bacteria involves enzymes different from those in archaea...

Pleurotus eryngii polysaccharides have been shown to exert significant biological activities to the host. However, few studies have been conducted on its effects on gastrointestinal tract (GIT) health alteration. In the present study, small intestinal and colonic proteome alterations generated by dietary supplementation with a novel homogeneous P. eryngii polysaccharide (PEP) in C57BL/6 mice, based on the isobaric tag for relative and absolute quantification (iTRAQ) proteomics were investigated. Compared to the control group, PEP supplementation resulted in a total of 113 and 194 significant differential proteins (DPs) in the small intestine and colon, respectively...

The Gram-positive bacterial cell wall is a large supramolecular structure and its assembly requires coordination of complex biosynthetic pathways. In the step that merges the two major biosynthetic pathways in Staphylococcus aureus cell wall as-sembly, conserved protein ligases attach wall teichoic acids to peptidoglycan, but the order of biosynthetic events is a longstanding question. Here, we use a chemical approach to define which of the possible peptidoglycan intermediates are substrates for wall-teichoic acid ligases, thereby establishing the order of cell wall assembly...

The emergence and ongoing spread of multidrug-resistant bacteria puts humans and other species at risk for potentially lethal infections. Thus, novel antibiotics or alternative approaches are needed to target drug-resistant bacteria, and metabolic modulation has been documented to improve antibiotic efficacy, but the relevant metabolic mechanisms require more studies. Here, we show that glutamate potentiates aminoglycoside antibiotics, resulting in improved elimination of antibiotic-resistant pathogens. When exploring the metabolic flux of glutamate, it was found that the enzymes that link the phosphoenolpyruvate (PEP)-pyruvate-AcCoA pathway to the TCA cycle were key players in this increased efficacy...

BACKGROUND: L-phenylalanine (L-Phe) is an essential amino acid for mammals and applications expand into human health and nutritional products. In this study, a system level engineering was conducted to enhance L-Phe biosynthesis in Escherichia coli. RESULTS: We inactivated the PTS system and recruited glucose uptake via combinatorial modulation of galP and glk to increase PEP supply in the Xllp01 strain. In addition, the HTH domain of the transcription factor TyrR was engineered to decrease the repression on the transcriptional levels of L-Phe pathway enzymes...

Glutaredoxin-1 (GRX-1), belonging to the oxidoreductase family, is a component of the endogenous antioxidant defense system. In this study, we evaluated the effects of PEP-1-GRX-1 in rabbit articular chondrocytes. We found that PEP-1-GRX-1 causes a loss of the differentiated chondrocyte phenotype. PEP-1-GRX-1-treated cells exhibited decreases in type II collagen expression and sulfated-proteoglycan synthesis in a dose- and time-dependent manner. PEP-1-GRX-1 causes endoplasmic reticulum (ER)-stress, as evidenced by increases in ER stress marker proteins, i...
