The identification of host factors involved in virus replication is important to understand virus life cycles better. Accordingly, we sought host factors that interact with the influenza viral nonstructural protein 2 by using coimmunoprecipitation followed by mass spectrometry. Among proteins associating with nonstructural protein 2, we focused on the β subunit of the F1Fo-ATPase, which receive...

OBJECTIVE Gender and diet have an important effect in cardiovascular disease and other aging-associated disorders, whose initiation and/or worsening seem to be delayed in females from different species and in animals subjected to caloric restriction (CR). The aim of the present study was to investigate whether cardiac muscle bioenergetic mitochondrial features could be responsible for these ben...

Dexamethasone—a potent synthetic glucocorticoid—has multiple diagnostic and therapeutic applications in wide range of age groups. However, the side-effects of dexamethasone (Dex) treatment including those on development are becoming increasingly apparent. Since the developmental processes are energy-dependent, we examined the effects of chronic Dex treatment on kinetics properties of liver mito...

Eclipta alba can be found growing wild in fallow lands of Bangladesh where it is considered as a weed by farmers. Traditional medicinal systems of the Indian subcontinent countries as well as tribal practitioners consider the plant to have diverse medicinal values and use it commonly for treatment of gastrointestinal disorders, respiratory tract disorders (including asthma), fever, hair loss an...

The aim of this study was to investigate selected proteomic markers of the metabolic phenotype of breast carcinomas as prognostic markers of cancer progression. For this purpose, a series of 101 breast carcinomas and 13 uninvolved breast samples were examined for quantitative differences in protein expression of mitochondrial and glycolytic markers. The beta-subunit of the mitochondrial H(+)-AT...

Various phytoconstituents obtained from nature have wide biological activities in chronic diseases and have wide therapeutic efficacy. The main advantage of using phytoconstituents is it provides free from adverse effects treatment where none of the medication can do. However, the physiochemical properties such as poor solubility, poor permeation, and non-targeting at the active site will creat...

several plant extracts and phytoconstituents, despite having excellent bioactivity in vitro, demonstrate less or no in vivo actions due to their poor lipid solubility or improper molecular size or destruction in gut. drug delivery system for polyphenolic phytoconstituents (phytosomes) was prepared by complexing polyphenolic phytoconstituents with phospholipid mainly phosphatidylcholine which bi...

Experiments are reported on the uni-site catalysis and the transition from uni-site to multi-site catalysis with bovine heart mitochondrial F1-ATPase. The very slow uni-site ATP hydrolysis is shown to occur without tightly bound nucleotides present and with or without Pi in the buffer. Measurements of the transition to higher rates and the amount of bound ATP committed to hydrolysis as the ATP ...

The N-terminal region of the bovine mitochondrial F1-ATPase inhibitor protein is frayed. In three independently isolated samples about 62% of chains start at glycine-1. A further 22% of chains start at residue 2, serine, and the remainder at residue 3, glutamic acid. No evidence can be found for alpha-N-formylglycine reported previously. The fraying may be a consequence of proteolytic processin...
