Description
We studied whether the accumulation of lipids in the fasted kidney are derived from lipoproteins or (non-esterified fatty acids) NEFAs. With overnight fasting, kidneys accumulated triglyceride, but had reduced levels of ceramide and glycosphingolipid species. Fasting led to a nearly 5-fold increase in kidney uptake of plasma [14C]oleic acid. Increasing circulating NEFAs using a ß adrenergic receptor agonist caused a 15-fold greater accumulation of lipid in the kidney, while mice with reduced NEFAs due to adipose tissue deficiency of adipose triglyceride lipase had reduced triglycerides. Cluster of differentiation (Cd)36 mRNA increased 2-fold, and angiopoietin-like 4 (Angptl4), an LPL inhibitor, increased 10-fold. Fasting-induced kidney lipid accumulation was not affected by inhibition of LPL with poloxamer 407 or by use of mice with induced genetic LPL deletion. Despite the increase in CD36 expression with fasting, genetic loss of CD36 did not alter fatty acid uptake or triglyceride accumulation. Our data demonstrate that fasting-induced triglyceride accumulation in the kidney correlates with the plasma concentrations of NEFAs, but is not due to uptake of lipoprotein lipids and does not involve the fatty acid transporter, CD36. Overall design: Mice (n=4-5/group) were either fasted for 16 hours or fed ad libitum. Kidneys were removed and snap frozen. RNA was extracted for sequencing.

Description
Bearing in mind the prevalent occurrence of sulfur deficiency in soils, it is highly essential to comprehend the molecular processes of plant response to the changing conditions of sulfur nutrition. As there is an increasing understanding of ubiquitin-proteasomal protein degradation system participation in nutrient deficiency response, we could predict its input to the sulfur metabolism as well. Therefore, we decided to investigate the consequences of proteasome malfunction in Arabidopsis in sulfur deficient conditions.

Proteasomal Degradation of Proteins Is Important for the Proper Transcriptional Response to Sulfur Deficiency Conditions in Plants.

Description
Objective Telmisartan, an angiotensin II type 1 (AT1) receptor blocker, and amlodipine, a calcium channel blocker, are antihypertensive agents clinically used as monotherapy or in combination. They exert beneficial cardiovascular effects independently of blood pressure lowering and classic mechanisms of action. In this study, we investigate molecular mechanisms responsible for the off-target effects of telmisartan and telmisartan-amlodipine in endothelial cells (EC), using an unbiased approach.
Publication Title
Telmisartan exerts pleiotropic effects in endothelial cells and promotes endothelial cell quiescence and survival.

Description
The goal of this experiment was to examine the innate immune response to helminth infection in the lung. Hookworms (like many other helminths) use an obligate migration pathway through the lung. Their infection has been characterized in the gut in detail, but early immune responses in the lung have not been fully characterized.
Publication Title
Innate immune responses to lung-stage helminth infection induce alternatively activated alveolar macrophages.
