2025-02-28
Introduction The first use of the term “autophagy” by a French physiologist, M. Anselmier, in a short article describing the effects of fasting in mice published in 1859, took place almost a century before Christian De Duve described it from a mechanistic point of view in a symposium on lysosomes i

While the yeasts and (see Glossary) each contain only one Aurora homolog, Ipl1p (increase in ploidy 1) and Ark1 (Aurora-related kinase 1), respectively 5, 6, , and Xenopus laevis contain two Aurora kinases: Aurora A and Aurora B [4]. Mammals have three Aurora kinases, A, B, and C (Figure 1). In anim

2025-02-28
The relative stereochemistry of both the major and minor diastereoisomer of (±)-2-(hydroxymethyl)blebbistatin (±)- (and thus (±)-2-(allyloxymethyl)blebbistatin (±)-) was determined with 1D-NOESY experiments (), as crystallization efforts failed. These experiments revealed an interaction between H an

We wanted to investigate the influence of substituents on the pyrazole ring on the activity, but only a few substituted pyrazole-3-carboxylic acids/esters were commercially available in useful amounts at a reasonable price, for example, 4- and 5-nitro-pyrazole-3-carboxylic acid. The preparation of 4

2025-02-28
Because ASK1 signaling in microglia and astrocytes is important during EAE, we hypothesized that a combination therapy that targets T cells along with microglia and astrocytes would further ameliorate the severity of EAE. We tested this hypothesis by applying valproic GSK461364 (VPA)—a short-chain

2025-02-28
There is a delicate balance between ROS generation and scavenging by the protective antioxidant defenses in the cell. Antioxidant systems present in the microcystin lr include enzymes like superoxide dismutase (SOD), catalases, glutathione peroxidases (GPxs) and peroxiredoxins (PRxs) (Fig. 3) [38].

Whereas allostery in the β cell is relatively understudied, significant progress has been made in understanding the physiology and mechanistic biology of how AMPK and its upstream kinases govern β cell function. LKB1 phosphorylates AMPKα at Thr172 [21], and loss of LKB1 in β cells abolishes phosphor

We recently identified a G9A-dependent epigenetic mechanism for transcriptional activation of the serine pathway in cancer cells (Ding et al., 2013). G9A, also known as EHMT2 and KMT1C, is a H3K9 methyltransferase that has a primary role in catalyzing H3K9me1 and H3K9me2 in euchromatin (Shinkai and

In 2008, a working group exposed 12-month-old transgenic mice (mutation for human amyloid precursor protein expression) and their non-transgenic littermates to isoflurane and halothane for 120min per day for five days. It was concluded that in the transgenic mouse there was overload of amyloid prote

While the mechanisms by which ALDH2 regulates cardiac responses to pathological stress remain unclear, the capillary rarefaction found in pressure-overloaded ALDH2 Tg hearts provides potential clues. Loss of capillary density and diminished endothelial function occur in pathological hypertrophy [46]

Adiponectin also suppresses inflammatory stimuli-induced NF-kappaB activation, which may significantly contribute to the anti-diabetic and anti-atherogenic effects of adiponectin (Ouchi et al., 2000). The downstream mediators of AdipoR1 and AdipoR2, RPPAR and AMPK increase inflammatory responses by

Numerous studies have shown that ω-3 PUFA incorporation into the lipid raft can affect the distribution and function of protein in the lipid raft by altering raft composition [25], [26], [27]. For example, DHA treatment excluded phospholipase D (PLD) from lipid raft toward non-lipid raft, resulting

We further analyzed selected hit compounds for their ability to inhibit human AdK in intact cells. Human 1321N1 astrocytoma monohydrochloride were utilized which were found to express AdK. The whole cell assay was performed using a 96-well format. The standard AdK inhibitor 5-iodotubercidin was emp

Results Discussion Utilizing a proteomic approach, we identified HSP90β as a protein that becomes associated with surface AChR in agrin-stimulated muscle cells. We demonstrate that HSP90β does not interact with the AChR directly; instead, via direct interaction with rapsyn, HSP90β becomes asso
