We studied the role of microsomal triglyceride transfer protein (MTP) in the synthesis, secretion, and cotranslational degradation of apolipoprotein (apo) B using nonhepatic COS-7 cells that expressed C-terminally truncated forms of apoB (from apoB15 to apoB94) with or without the large subunit of human MTP. With the exception of apoB15 and apoB18, secretion of all of the apoB forms was stimula...
Introduction Cheilectomy surgery has been shown to provide pain relief for patients with hallux rigidus [1], however limited data exists regarding the effectiveness of this surgery in reestablishing normal first metatarsophalangeal (1st MTP) joint kinematics. A recent dynamic gait study has reported only modest improvement in 1st MTP motion following surgery, thus implicating the persistence of...
ماهی سفید Rutilus frisii kutum یکی از گونه های ارزشمند تجاری و بومی دریای خزر است. هدف از پژوهش حاضر بررسی اثرات به کارگیری آنتاگونیست های نسل سوم سیستم دوپامینرژیک و آگونیست و آنتاگونیست سیستم آدرنرژیک به همراه هورمون های هیپوتالاموسی، آگونیست Buserelin) GnRH) و Ovaprim بر تغییرات سرمی هورمون های (17β-estradiol (E2 و (17α-hydroxyprogeterone (17α-OHP در گون...
Hepatocyte growth factor (HGF) has various effects especially on epithelial cells. However, the precise role of HGF on lipogenesis is still not fully understood. A high-fat diet was administered to HGF transgenic mice and wild-type control mice in vivo. Furthermore, recombinant human HGF (rhHGF) was administered to HepG2 cell line in vitro. We performed an analysis regarding the factors relatin...
Obesity causes lipid accumulation in the heart and may lead to lipotoxic heart disease. Traditionally, the size of the cardiac triglyceride pool is thought to reflect the balance between uptake and beta-oxidation of fatty acids. However, triglycerides can also be exported from cardiomyocytes via secretion of apolipoproteinB-containing (apoB) lipoproteins. Lipoprotein formation depends on expres...
Abetalipoproteinemia (ABL) is a rare Mendelian disorder of lipid metabolism due to genetic deficiency in microsomal triglyceride transfer protein (MTP). It is associated with defects in MTP-mediated lipid transfer onto apolipoprotein B (APOB) and impaired secretion of APOB-containing lipoproteins. Recently, MTP was shown to regulate the CD1 family of lipid antigen-presenting molecules, but litt...
BACKGROUND The use of microsomal triglyceride transfer protein (MTP) inhibitors is limited to severe hyperlipidemias because of associated hepatosteatosis and gastrointestinal adverse effects. Comprehensive knowledge about the structure-function of MTP might help design new molecules that avoid steatosis. Characterization of mutations in MTP causing abetalipoproteinemia has revealed that the ce...
The microsomal triglyceride transfer protein (MTP) is required for the assembly and secretion of apolipoprotein B (apoB)-containing lipoproteins from liver and intestine. We set out to study the phenotypic modulation of all common genetic variants in the MTP gene. In addition, we aimed at characterizing the association between the various polymorphisms. A total of 564 healthy men were genotyped...
The reduction of hepatic microsomal transfer protein (MTP) activity results in fatty liver, worsening hepatic steatosis and fibrosis in chronic hepatitis C (CHC). The G allele of the MTP gene promoter, -493G/T, has been associated with lower transcriptional activity than the T allele. We investigated this association with metabolic and histological variables in patients with CHC. A total of 174...
The high silica Mn-substituted MFI metallosilicate catalyst with Si/Al molar ratio of 220 and Si/Mn molar ratio of 50 was successfully synthesized by hydrothermal method. The catalyst sample was appropriately characterized by XRD, FE-SEM, EDX and BET techniques. The Mn-substituted MFI metallosilicate has not been reported as the potential catalyst for the methanol to propylene (MTP) reaction. T...
