New mutations at the imprinted Gnas cluster show gene dosage effects of Gsα in postnatal growth and implicate XLαs in bone and fat metabolism, but not in suckling [PDF]

open access: yes, 2012
The imprinted Gnas cluster is involved in obesity, energy metabolism, feeding behavior, and viability. Relative contribution of paternally expressed proteins XLαs, XLN1, and ALEX or a double dose of maternally expressed Gsα to phenotype has not been ...

A comparison of the innate flexibilities of six chains in F$_1$-ATPase with identical secondary and tertiary folds; 3 active enzymes and 3 structural proteins [PDF]

open access: yesAIP Structural Dynamics, 4, 044001, 2017, 2016
The $\alpha$ and $\beta$ subunits comprising the hexameric assembly of F1-ATPase share a high degree of structural identity, though low primary identity. Each subunit binds nucleotide in similar pockets, yet only $\beta$ subunits are catalytically active. Why? We re-examine their internal symmetry axes and observe interesting differences. Dividing each

Gi- and Gs-coupled GPCRs show different modes of G-protein binding. [PDF]

open access: yes, 2018
More than two decades ago, the activation mechanism for the membrane-bound photoreceptor and prototypical G protein-coupled receptor (GPCR) rhodopsin was uncovered.

Lipocalin‐2 activates hepatic stellate cells and promotes nonalcoholic steatohepatitis in high‐fat diet–fed Ob/Ob mice

open access: yesHepatology, EarlyView., 2022
Graphical summary of obesity‐induced NASH progression by LCN2 targeted to HSC activation. Abstract Background and Aims In obesity and type 2 diabetes mellitus, leptin promotes insulin resistance and contributes to the progression of NASH via activation of hepatic stellate cells (HSCs).

Mechanisms underlying synergism between circularized tumor necrosis factor‐related apoptosis inducing ligand and bortezomib in bortezomib‐sensitive or ‐resistant myeloma cells

open access: yesHematological Oncology, Volume 40, Issue 5, Page 999-1008, December 2022., 2022
Abstract Mechanisms underlying interactions between a novel, clinically relevant circularized tumor necrosis factor‐related apoptosis inducing ligand (TRAIL) agonist, circularly permuted TRAIL (CPT) have been examined in multiple myeloma (MM) cells sensitive or resistant to bortezomib (BTZ).

Regulation of P450-mediated permethrin resistance in Culex quinquefasciatus by the GPCR/Gαs/AC/cAMP/PKA signaling cascade

open access: yesBiochemistry and Biophysics Reports, 2017
This study explores the role of G-protein-coupled receptor-intracellular signaling in the development of P450-mediated insecticide resistance in mosquitoes, Culex quinquefasciatus, focusing on the essential function of the GPCRs and their downstream ...

ER/K linked GPCR-G protein fusions systematically modulate second messenger response in cells. [PDF]

open access: yes, 2017
FRET and BRET approaches are well established for detecting ligand induced GPCR-G protein interactions in cells. Currently, FRET/BRET assays rely on co-expression of GPCR and G protein, and hence depend on the stoichiometry and expression levels of the ...

Structure of $^{10}_Λ$Be and $^{10}_Λ$B hypernuclei studied with the four-body cluster model [PDF]

open access: yesProg. Theor. Phys. 128 (2012), 105-124, 2012
The structure of the isodoublet hypernuclei, $^{10}_{\Lambda}$B and $^{10}_{\Lambda}$Be within the framework of an $\alpha +\alpha +\Lambda +N$ four-body cluster model is studied. Interactions between the constituent subunits are determined so as to reproduce reasonably well the observed low-energy properties of the $\alpha \alpha$, $\alpha N$, $\alpha

Proteomic profiling of impaired excitation–contraction coupling and abnormal calcium handling in muscular dystrophy

open access: yesPROTEOMICS, Volume 22, Issue 23-24, December 2022., 2022
Abstract The X‐linked inherited neuromuscular disorder Duchenne muscular dystrophy is characterised by primary abnormalities in the membrane cytoskeletal component dystrophin. The almost complete absence of the Dp427‐M isoform of dystrophin in skeletal muscles renders contractile fibres more susceptible to progressive degeneration and a leaky ...
