A 61-year-old man with a history of total gastrectomy for cancer with Roux-en-Y reconstruction showed severe postprandial hypoglycemia accompanied by endogenous hyperinsulinemia. Abdominal ultrasonography and contrast-enhanced computed tomography showed no abnormal findings in the pancreas. A selective arterial secretagogue...

Calorie restriction (CR) may exert an anti-aging effect through a metabolic adaptation to limited energy intake. The present study investigated the effect of CR on insulin signaling in response to glucose load in the epididymal adipose tissue of male...

Measurement of the nuclear concentration of α-ketoglutarate during adipocyte differentiation by using a fluorescence resonance energy transfer-based biosensor with nuclear localization signals.

α-Ketoglutarate (α-KG) also known as 2-oxoglutarate (2-OG) is an intermediate metabolite in the tricarboxylic acid (TCA) cycle and is also produced by the deamination of glutamate. It is an indispensable cofactor for a series of 2-oxoglutarate-dependent oxygenases including epigenetic...

The fossil record of terrestrialization documents notable shifts in the environmental and physiological tolerances of many animal and plant groups. However, for certain significant components of modern freshwater and terrestrial environments, the transition out of marine settings remains largely...

Opt Express. 2008 Feb 18;16(4):2614-20. doi: 10.1364/oe.16.002614.

We report the fabrication of nanoparticles that contain metal nanoclusters at the surface of the CaO-Bi(2)O(3)-B(2)O(3)-Al(2)O(3)-TiO2 glass using XeCl laser irradiation. We have demonstrated that the surface morphology such as that containing nanoparticles or a smooth flat surface can...

Acetylation of the influenza A virus polymerase subunit PA in the N-terminal domain positively regulates its endonuclease activity.

The post-translational acetylation of lysine residues is found in many nonhistone proteins and is involved in a wide range of biological processes. Recently, we showed that the nucleoprotein of the influenza A virus is acetylated by histone acetyltransferases (HATs),...

A genetically tractable jellyfish model for systems and evolutionary neuroscience.

Jellyfish are radially symmetric organisms without a brain that arose more than 500 million years ago. They achieve organismal behaviors through coordinated interactions between autonomously functioning body parts. Jellyfish neurons have been studied electrophysiologically, but not at the systems...

Sendai virus (SeV) accessory protein C limits the generation of double-stranded RNAs, defective interfering RNAs, or both during viral transcription and replication, thereby limiting interferon-β production. Our recent in vitro analyses on murine macrophage cell lines demonstrated that this...

To develop combination immunotherapies for gastric cancers, immunologically well-characterized preclinical models are crucial. Here, we leveraged two transplantable murine gastric cancer cell lines, YTN2 and YTN16, derived from the same parental line but differing in their susceptibility to immune...
