Atorvastatin action involves diminished recovery of hepatic HMG-CoA reductase activity

Journal of Lipid Research, 1998
The effects of atorvastatin on the expression of the hepatic HMG-CoA reductase and LDL receptor genes were investigated in rats. Like the other statins, atorvastatin increased the rate of degradation and presumably cycling of the hepatic LDL receptor. In

Evaluation of the Stress Effect on Expression of BEST-5 Gene in Gultured Rat Hepatocytes and Cloning of This Gene [PDF]

Journal of Kerman University of Medical Sciences, 2006
Introduction:Liver has important roles in body metabolic regulation and for this reason hepatocytes are used worldwide.Investigations showed that isolation of hepatocytes causes activation of stress related genes.The aim of this study was to study the ...

Cell type-specific over-expression of chromosome 21 genes in fibroblasts and fetal hearts with trisomy 21

BMC Medical Genetics, 2006
Background Down syndrome (DS) is caused by trisomy 21 (+21), but the aberrations in gene expression resulting from this chromosomal aneuploidy are not yet completely understood.

Optimized RNA Extraction and Northern Hybridization in Streptomycetes

Biological Procedures Online, 2010
Northern blot hybridization is a useful tool for analyzing transcript patterns. To get a picture of what really occurs in vivo, it is necessary to use a protocol allowing full protection of the RNA integrity and recovery and unbiased transfer of the ...

Identification and characteristics of microRNAs from Bombyx mori

BMC Genomics, 2008
Background MicroRNAs (miRNAs) are small RNA molecules that regulate gene expression by targeting messenger RNAs (mRNAs) and causing mRNA cleavage or translation blockage. Of the 355 Arthropod miRNAs that have been identified, only 21 are B.

Polysome Profiling Analysis

Bio-Protocol, 2013
Polysome profiling is a method that allows monitoring of translation activity of mRNAs in cells and tissues. Once each polysome fractions are collected, the translation activity of each mRNA is analyzed using various molecular biology techniques such as ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

FEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells

FEBS Open Bio, EarlyView.
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Yeast Gcn2 retains activity following humanization of its auto‐phosphorylation region

FEBS Open Bio, EarlyView.
Using Saccharomyces cerevisiae as a model to study Gcn2 activation and regulation is limited by the lack of antibodies detecting phosphorylated Gcn2. To overcome this, we engineered Gcn2‐HsC, a yeast Gcn2 variant recognizable by commercial anti‐human phospho‐GCN2 antibodies.
