Amino acid intakes are associated with bone mineral density and prevalence of low bone mass in women: evidence from discordant monozygotic twins [PDF]

, 2015
Although a higher protein intake, particularly from vegetable sources, has been shown to be associated with higher bone mineral density (BMD) the relative impact of specific amino acids (AA) on BMD and risk of osteoporosis remains to be determined ...

Markerless Mutagenesis inMethanococcus maripaludisDemonstrates Roles for Alanine Dehydrogenase, Alanine Racemase, and Alanine Permease [PDF]

Journal of Bacteriology, 2005
ABSTRACTAmong the archaea,Methanococcus maripaludishas the unusual ability to usel- ord-alanine as a nitrogen source. To understand how this occurs, we tested the roles of three adjacent genes encoding homologs of alanine dehydrogenase, alanine racemase, and alanine permease.

Ion channel function of polycystin‐2/polycystin‐1 heteromer revealed by structure‐guided mutagenesis

FEBS Letters, EarlyView.
Mutations in polycystin‐1 (PC1) or polycystin‐2 (PC2) cause autosomal‐dominant polycystic kidney disease (ADPKD). We generated a novel gain‐of‐function PC2/PC1 heteromeric ion channel by mutating pore‐blocking residues. Moreover, we demonstrated that PC2 will preferentially assemble with PC1 to form heteromeric complexes when PC1 is co‐expressed ...

Changes in alanine aminotransfearase, aspartate aminotransfearase in blasma, kidney and liver in rabbits treated with cadmium chloride [PDF]

Iraqi Journal of Veterinary Sciences, 2006
The study was designed to investigate the subchronic toxic effect of cadmium chloride administered orally on alanine aminotransfearase (ALT), aspartate aminotransfearase (AST) activity and certain tissues in adult male rabbits.

Binding of small interfering RNA molecules is crucial for RNA interference suppressor activity of rice hoja blanca virus NS3 in plants [PDF]

, 2009
The NS3 protein of rice hoja blanca tenuivirus represents a viral suppressor of RNAi that sequesters small interfering (si)RNAs in vitro. To determine whether this siRNA binding property is the critical determinant for the suppressor activity of NS3, an ...

Interaction Entropy for Computational Alanine Scanning

Journal of Chemical Information and Modeling, 2017
The theoretical calculation of protein-protein binding free energy is a grand challenge in computational biology. Accurate prediction of critical residues along with their specific and quantitative contributions to protein-protein binding free energy is ...

Decoding the dual role of autophagy in cancer through transcriptional and epigenetic regulation

FEBS Letters, EarlyView.
Transcriptional and epigenetic regulation controls autophagy, which exerts context‐dependent effects on cancer: Autophagy suppresses tumorigenesis by maintaining cellular homeostasis or promotes tumor progression by supporting survival under stress. In this “In a Nutshell” article, we explore the intricate mechanisms of the dual function of autophagy ...

Study of the chemical evolution and spectral signatures of some interstellar precursor molecules of adenine, glycine alanine [PDF]

2013NewA...20...15M, 2012
We carry out a quantum chemical calculation to obtain the infrared and electronic absorption spectra of several complex molecules of the interstellar medium (ISM). These molecules are the precursors of adenine, glycine & alanine. They could be produced in the gas phase as well as in the ice phase.
