Teresa F Pais et al.
Journal of neuroinflammation, 5, 43-43 (2008-10-11)
Microglia are macrophage-like cells that constantly sense the microenvironment within the central nervous system (CNS). In the event of neuronal stress or injury, microglial cells rapidly react and change their phenotype. This response may lead to a deleterious type of

A panel of retinoids and carotenoids was screened as potential inducers of CYP3A4 through the RXR/VDR-mediated signaling pathway. Transient transfection assays revealed that 3 out of 12 retinoids screened transactivated RXRalpha/VDR and induced CYP3A4 reporter activity. These three retinoids are

Lipids in health and disease, 10, 37-37 (2011-03-01)
It is well known that high fat diets (HFDs) induce obesity and an increase in proinflammatory adipokines. Interleukin-6 (IL-6) is considered the major inflammatory mediator in obesity. Obesity is associated with a vitamin deficiency, especially of vitamins E and D3.
Sandeep Dayal et al.
PloS one, 6(9), e24571-e24571 (2011-09-29)
Antibodies are assembled by a highly orchestrated series of recombination events during B cell development. One of these events, class switch recombination, is required to produce the IgG, IgE and IgA antibody isotypes characteristic of a secondary immune response. The
Muslima Chowdhury et al.
Proceedings of the National Academy of Sciences of the United States of America, 105(41), 15872-15877 (2008-10-07)
Ig class switch recombination (CSR) is initiated by activation-induced cytidine deaminase (AID) mediated deamination of the switch (S) regions; the resultant mismatch is processed to yield the DNA breaks required for recombination. Whereas many of the pathways involved in the

Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) is a dual-function phosphatase with tumor suppressor function compromised in a wide spectrum of cancers. Because tissue polarity and architecture are crucial modulators of normal and malignant behavior, we postulated that

Although Akt is known to play a role in human cancer, the relative contribution of its three isoforms to oncogenesis remains to be determined. We expressed each isoform individually in an Akt1(-/-)/Akt2(-/-)/Akt3(-/-) cell line. MicroRNA profiling of growth factor-stimulated cells
Valerie L R M Verstraeten et al.
Histochemistry and cell biology, 135(3), 251-261 (2011-02-26)
A thorough understanding of fat cell biology is necessary to counter the epidemic of obesity. Although molecular pathways governing adipogenesis are well delineated, the structure of the nuclear lamina and nuclear-cytoskeleton junction in this process are not. The identification of
Shanmugam Sivabalan et al.
International archives of medicine, 1(1), 7-7 (2008-05-27)
The role of cortisol and its increased action/availability is implicated in the pathogenesis of insulin resistance associated with obesity and metabolic syndrome but the mechanism of increased action/availability is not known. Availability of several other lipophilic hormones, drugs and pollutants
Jun Zhang et al.
EMBO reports, 21(9), e49898-e49898 (2020-07-11)
Nutrient sensing by the mTOR complex 1 (mTORC1) requires its translocation to the lysosomal membrane. Upon amino acids removal, mTORC1 becomes cytosolic and inactive, yet its precise subcellular localization and the mechanism of inhibition remain elusive. Here, we identified Aster-C
Chen Yanting et al.
Journal of dairy science, 101(2), 1601-1615 (2017-11-21)
Differentiation and lipid metabolism of adipocytes have a great influence on milk performance, health, and feed efficiency of dairy cows. The effects of dietary long-chain fatty acids (FA) on adipogenesis and lipogenesis of dairy cows are often confounded by other
Huili Li et al.
Molecular cancer, 10, 100-100 (2011-08-23)
The transcription factor, CCAAT enhancer binding protein-β (C/EBPβ), is expressed as several distinct protein isoforms (LAP1, LAP2 and LIP) that have opposing actions in cellular proliferation and differentiation. Increases in the ratio of LIP/LAP are associated with aggressive, metastatic breast
Ming Wu et al.
PloS one, 4(12), e8040-e8040 (2009-12-04)
A major challenge in systems biology is to develop a detailed dynamic understanding of the functions and behaviors in a particular cellular system, which depends on the elements and their inter-relationships in a specific network. Computational modeling plays an integral
Per Magnus Haram et al.
Cardiovascular research, 81(4), 723-732 (2008-12-03)
The recent development of a rat model that closely resembles the metabolic syndrome allows to study the mechanisms of amelioration of the syndrome by exercise training. Here, we compared the effectiveness for reducing cardiovascular risk factors by exercise training programmes
Delong Meng et al.
The Journal of biological chemistry, 295(10), 2890-2899 (2020-02-06)
Nutrient sensing by cells is crucial, and when this sensing mechanism is disturbed, human disease can occur. mTOR complex 1 (mTORC1) senses amino acids to control cell growth, metabolism, and autophagy. Leucine, arginine, and methionine signal to mTORC1 through the

PloS one, 6(4), e18872-e18872 (2011-04-29)
Epithelial ovarian cancer is an aggressive and deadly disease and understanding its invasion mechanisms is critical for its treatment. We sought to study the penetration/invasion of ovarian tumor cells into extracellular matrices (ECMs) using a fibroblast-derived three-dimensional (3D) culture model
Jason Aoto et al.

Browning of subcutaneous white fat (iWAT) involves several reprograming events, but the underlying mechanisms are incompletely understood. Here we show that the transcription factor Hlx is selectively expressed in brown adipose tissue (BAT) and iWAT, and is translationally upregulated by

The mammalian target of rapamycin complex 1 (mTORC1) integrates nutrients, growth factors, stress, and energy status to regulate cell growth and metabolism. Amino acids promote mTORC1 lysosomal localization and subsequent activation. However, the subcellular location or interacting proteins of mTORC1
Sungsoo Na et al.

It is widely postulated that mechanotransduction is initiated at the local force-membrane interface by inducing local conformational changes of proteins, similar to soluble ligand-induced signal transduction. However, all published reports are limited in time scale to address this fundamental issue.
