Diffuse myofiber necrosis in the context of inflammatory myopathy is the hallmark of immune‐mediated necrotizing myopathy (IMNM). We have previously shown that skeletal muscle fibers of IMNM patients may display nonrimmed vacuoles and sarcoplasmic irregularities. The …

Human umbilical endothelial cells (HUVECs) have a sex: characterisation of the phenotype of male and female cells.

Biol Sex Differ. 2014 Dec 14;5(1):18. doi: 10.1186/s13293-014-0018-2. eCollection 2014.

BACKGROUND: Human umbilical endothelial cells (HUVECs) are widely used to study the endothelial physiology and pathology that might be involved in sex and gender differences detected at the cardiovascular level. This study evaluated whether HUVECs are sexually dimorphic in...

RNA-Seq Study of Microbially Induced Hemocyte Transcripts from Larval Heliothis virescens (Lepidoptera: Noctuidae).

PMID: 26466627
Insects. 2012 Aug 14;3(3):743-62. doi: 10.3390/insects3030743.

Larvae of the tobacco budworm are major polyphagous pests throughout the Americas. Development of effective microbial biopesticides for this and related noctuid pests has been stymied by the natural resistance mediated innate immune response. Hemocytes play an early and...

Intracellular Ca(2+) signaling: A novel player in the canonical mTOR-controlled autophagy pathway.

Communicative & integrative biology

Decuypere JP, Paudel RC, Parys J, Bultynck G.
PMID: 24265855
Commun Integr Biol. 2013 Sep 01;6(5):e25429. doi: 10.4161/cib.25429. Epub 2013 Jun 25.

Functional intracellular Ca(2+) signaling is essential for the upregulation of the canonical mTOR-controlled autophagy pathway triggered by rapamycin or by nutrient deprivation. Moreover, modifications in the Ca(2+)-signaling machinery coincide with autophagy stimulation. This results in enhanced intracellular Ca(2+) signaling...

Cell Death in the Developing Brain after Hypoxia-Ischemia.

Perinatal insults such as hypoxia-ischemia induces secondary brain injury. In order to develop the next generation of neuroprotective therapies, we urgently need to understand the underlying molecular mechanisms leading to cell death. The cell death mechanisms have been shown...

Reversal of intramyocellular lipid accumulation by lipophagy and a p62-mediated pathway.

Cell death discovery

We have previously observed the reversal of lipid droplet deposition in skeletal muscle of morbidly obese patients following bariatric surgery. We now investigated whether activation of autophagy is the mechanism underlying this observation. For this purpose, we incubated rat...

Targeting LAMP2 in human cerebrospinal fluid with a combination of immunopurification and high resolution parallel reaction monitoring mass spectrometry.

BACKGROUND: Alzheimer's disease is the most common form of dementia. An increasing body of evidence suggests that endo-lysosomal dysfunction is a pathogenic mechanism of Alzheimer's disease. Thus there is a potential for proteins involved in the normal function of...

Autophagy promotes degradation of internalized collagen and regulates distribution of focal adhesions to suppress cell adhesion.

Adhesion of cells to the extracellular matrix (ECM) via focal adhesions (FAs) is crucial for cell survival, migration, and differentiation. Although the regulation of FAs, including by integrins and the ECM, is important to cell behavior, how FAs are...

No-flow ischemia occurs during cardiac arrest, hemorrhagic shock, liver resection and transplantation. Recovery of blood flow and normal physiological pH, however, irreversibly injures the liver and other tissues. Although the liver has the powerful machinery for mitochondrial quality control,...

Autophagy is a self-protection process against reactive oxygen species (ROS). The intracellular level of ROS increased when cells were cultured under nutrient starvation. Antioxidants such as glutathione and ascorbic acid play an important role in ROS removal. However, the...
