Racial difference in Acylation Stimulating Protein (ASP) correlates to triglyceride in non-obese and obese African American and Caucasian women
(East Carolina University, 2009-04-17)Background: Acylation Stimulating Protein (ASP) has been shown to influence adipose tissue triglyceride (TG) storage. The aim was to examine ethnic differences in ASP and leptin levels in relation to lipid profiles and ... -
Regulation of lipoprotein lipase mRNA content in 3T3-L1 cells by tumour necrosis factor.
(East Carolina University, 1988-02-01)Tumour necrosis factor (TNF) was previously shown to suppress lipoprotein lipase (LPL) synthesis and activity in 3T3-L1 adipocytes. The present study examined the effect ofTNF on amounts ofmRNA for LPL in 3T3-Ll cells. ... -
Resolving the Role of POU1F1 in Human Growth Hormone Locus Activation
(East Carolina University, 2012)The human growth hormone gene ( hGH-N) is regulated by a distal locus control region (LCR) composed of five deoxyribonuclease I hypersensitive sites (HSs). The region encompassing HSI and HSII contains the predominant ... -
The RXR-alpha C-terminus T462 is a NMR sensor for coactivator peptide binding
(East Carolina University, 2008-02-22)The C-terminal activation function-2 (AF-2) helix plays a crucial role in retinoid X receptor alpha (RXRα)-mediated gene expression. Here, we report a nuclear magnetic resonance (NMR) study of the RXRα ligand-binding domain ... -
Some Cardiomyopathy-Causing Troponin I Mutations Stabilize a Functional Intermediate Actin State
(East Carolina University, 2009-03-18)We examined four cardiomyopathy-causing mutations of troponin I that appear to disturb function by altering the distribution of thin filament states. The R193H (mouse) troponin I mutant had greater than normal actin-activated ... -
Tropomyosin Dynamics in Cardiac Thin Filaments: A Multisite Förster Resonance Energy Transfer and Anisotropy Study
(East Carolina University, 2008-06)Cryoelectron microscopy studies have identified distinct locations of tropomyosin (Tm) within the Ca21-free, Ca21-saturated, and myosin-S1-saturated states of the thin filament. On the other hand, steady-state Förster ... -
Troponin-tropomyosin: an allosteric switch or a steric blocker?
(East Carolina University, 2002-08)The interaction of myosin subfragment 1 (S1) with actin-tropomyosin-troponin (regulated actin) is highly nucleotide dependent. The binding of S1 or S1-ADP (but not S1-ATP nor N,N - -phenylenedimaleimide-modified S1-ATP) ... -
Tumour necrosis factor-alpha regulates expression of the CCAAT-enhancer-binding proteins (C/EBPs) alpha and beta and determines the occupation of the C/EBP site in the promoter of the insulin-responsive glucose-transporter gene in 3T3-L1 adipocytes.
(East Carolina University, 1999-03-15)We have demonstrated previously that treatment of 3T3-L1 adipocytes with tumour necrosis factor-alpha (TNF) results in a rapid (4 h) and significant (75–80%) reduction in the rate of transcription of the GLUT4 gene. Control ...
