Laea, a regulator of secondary metabolism in aspergillus spp.
Secondary metabolites, or biochemical indicators of fungal development, are of intense interest to humankind due to their pharmaceutical and/or toxic properties. We present here a novel Aspergillus nuclear protein, LaeA, as a global regulator of secondary metabolism in this genus. Deletion of laeA (laeA) blocks the expression of metabolic gene clusters, including the sterigmatocystin ...

A novel heme-regulatory motif mediates heme-dependent degradation of the circadian factor period 2
Although efforts have been made to identify circadian-controlled genes regulating cell cycle progression and cell death, little is known about the metabolic signals modulating circadian regulation of gene expression. We identify heme, an iron-containing prosthetic group, as a regulatory ligand controlling human Period-2 (hPer2) stability. Furthermore, we define a novel heme-regulatory motif ...

Molecular and physiological responses to titanium dioxide and cerium oxide nanoparticles in arabidopsis
Changes in tissue transcriptomes and productivity of Arabidopsis thaliana were investigated during exposure of plants to two widely used engineered metal oxide nanoparticles, titanium dioxide (nano‐titanium) and cerium dioxide (nano‐cerium). Microarray analyses confirmed that exposure to either nanoparticle altered the transcriptomes of rosette leaves and roots, with comparatively larger ...

Big data analytics identifies metabolic inhibitors and promoters for productivity improvement and optimization of monoclonal antibody (mAb) production process
The bioreactor’s environment and media contents affect the metabolism and productivity of a cell line. Traditional analytics like pH, temperature, dissolved gas levels, and titer reveals useful but incomplete information about the cells’ metabolism. Extracellular metabolites and nutrients in the cell media can be monitored to provide some information about the health of the cells. ...

Magnesium ions improving the growth and organics reduction of
Rhodospirillum rubrum cultivated in sewage through regulating energy metabolism pathwaysRhodospirillum rubrum has the potential for biomass resource recycling combined with sewage purification. However, low biomass production and yield restricts the potential for sewage purification. This research investigated the improvement of biomass production, yield and organics reduction by Mg2+ in R. rubrum wastewater treatment. Results showed that with optimal dosage (120 mg/L), ...

In Silico Development of Combinatorial Therapeutic Approaches Targeting Key Signaling Pathways in Metabolic Syndrome
Purpose Dysregulations of key signaling pathways in metabolic syndrome are multifactorial, eventually leading to cardiovascular events. Hyperglycemia in conjunction with dyslipidemia induces insulin resistance and provokes release of proinflammatory cytokines resulting in chronic inflammation, accelerated lipid peroxidation with further development of atherosclerotic alterations and diabetes. We ...

Development of mRNA-Directed Delivery - LNP Delivery System
During the COVID-19 pandemic, the success of mRNA vaccines has greatly propelled the development of mRNA therapeutics. mRNA is a negatively charged nucleic acid that serves as a template for protein synthesis in ribosomes. Despite its utility, the instability of mRNA necessitates appropriate carriers for in vivo delivery. Currently, lipid nanoparticles (LNPs) are the most mature approach for ...

Organic Acids Analysis
The organism undergoes thousands of biochemical reactions every moment to maintain our growth, development and energy metabolism. Under normal circumstances, these biochemical reactions proceed smoothly step by step through various cycles or certain steps. The process by which the body changes carbohydrates, amino acids, and fats from nutrients to absorbable substances and wastes is called the ...

Novel Mechanism of Glycosylation Regulating Pancreatic Cancer Reveled
Pancreatic cancer is a highly malignant digestive system tumor, and the five-year survival rate of patients after diagnosis is only about 10%. Changes in metabolism are one of the important features of tumor cells. Tumor cells undergo metabolic reprogramming to generate the substances, energy, and redox forces required for their rapid proliferation. The proliferation of pancreatic ductal ...

The Importance of Water for the Body - Puroxi
Common Contaminants in Your Tap Water. Antibiotic Use Increased In 2010 Food Animal Production Sales of antibiotics intended for domestic food animals increased from 2009 to 2010, according to new data released by the U.S. Food and Drug Administration. The Pew Health Group analyzed the numbers in the report, the second-ever issued by FDA, which showed a boost of 6.7 percent, from 28.8 million ...

Regulation of cancer by therapeutic vaccination and dietary bio-modulation involving organ-specific mitochondria
Cancer therapy should aim to prevent recurrent disease. Surgery and toxic treatments remove only symptoms associated with cancer without trying to intervene in the aetiology, therefore the disease may recur. The autologous cancer vaccine supplemented with bio-modulation might fulfil requirements for effective tumour therapy. The autologous tumour vaccine is formed in the same way as our bodily ...

AMPK Signaling Pathway and Function
AMPK (Adenosine 5'-monophosphate (AMP)-activated protein kinase), as an important kinase regulating energy homeostasis, is one of the central regulators of eukaryotic cell and organism metabolism. It is responsible for regulating cellular capacity input and output and maintaining the smooth functioning of cellular physiological activities. AMPK is also a key protein involved in various signaling ...

Abstract 15053: New Insights into the Development of the Protease Proprotein Convertase Subtilisin-Like Kexin Type 9 Antagonists
Abstract Protease proprotein convertase subtilisin-like kexin type 9 (PCSK9) is an important target for the treatment of hypercholesterolemia. PCSK9 is synthesized as a zymogen that undergoes autocatalytic processing and secretion. Secreted PCSK9 binds to the LDL-receptor (LDLR) and chaperones it to the degradation pathway. Several pharmaceutical companies have developed injectable mAb PCSK9 ...

Detailed Introduction to Steroids Analysis
Steroid hormone is a class of compounds that contain cyclopentane polyhydrophenanthrene structure formed by cholesterol and catalyzed by cytochrome P450 enzymes. Steroid hormones mainly include adrenocorticotropic hormones secreted by the adrenal cortex and sex hormones secreted by the gonads, which are mainly divided into four categories: progesterone, corticosteroid, estrogen and androgen. ...

Mitochondrial Proteomics
Mitochondria are important organelles of eukaryotic cells and play a key role in the regulation of cellular energy metabolism, biosynthesis and cell death (including apoptosis and programmed cell necrosis). In addition, mitochondria are involved in important physiological processes such as tricarboxylic acid cycle, fatty acid and amino acid oxidation, and regulation of calcium ion homeostasis. ...

Introduction to Glucosidase
Glucosidase is a large class of enzymes in glycoside hydrolase (EC 3.2.1). It is named because it can hydrolyze the glucoside bond and release a molecule of glucose. Glucosidase has a wide range of sources, and it exists in almost all organisms with cellular structure that use carbohydrates as energy sources. According to the classification of the Carbohydrate-Active enZYmes Database (CAZy) ...

Food Nutrition Enhancers
Food nutrition enhancer, also called food nutritional fortifier, refers to natural or synthetic nutrients added to food in order to increase its nutritional content. It can not only supplements people's daily nutritional intake, but also has a positive effect on disease prevention and control. The food nutrition enhancers can be divided into four main categories as following. Vitamins Vitamins ...
