Plastid intramembrane proteolysis

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2015
Progress in the field of regulated intramembrane proteolysis (RIP) in recent years has not surpassed plant biology. Nevertheless, reports on RIP in plants, and especially in chloroplasts, are still scarce. Of the four different families of intramembrane proteases, only two have been linked to chloroplasts so far, rhomboids and site-2 proteases (S2Ps ...

The MMP‐9/TIMP‐1 Ratio and Concentrations of Osteopontin Are Elevated in Cerebrospinal Fluid of People With Multiple Sclerosis and Decrease After Autologous Hematopoietic Stem Cell Transplantation

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives To evaluate the utility of cerebrospinal fluid (CSF) biomarkers—matrix metalloproteinase‐9 (MMP‐9), tissue inhibitor of metalloproteinases‐1 (TIMP‐1), the MMP‐9/TIMP‐1 ratio, and osteopontin (OPN)—as indicators of blood–brain barrier (BBB) integrity and disease activity in people with relapsing–remitting multiple sclerosis (pwMS ...

Proteolisis status in the oral mucosa of rats after “mild” stress

Journal of Education, Health and Sport
Background. Stress is one of the main causes of the development of most diseases. The role of proteolysis in the pathogenesis of post-stress reactions is not sufficiently elucidated. Aim.

Non-canonical proteolytic activation of human prothrombin by subtilisin from Bacillus subtilis may shift the procoagulant\ue2\u80\u93anticoagulant equilibrium toward thrombosis [PDF]

, 2017
Blood coagulation is a finely regulated physiological process culminating with the factor Xa (FXa)-mediated conversion of the prothrombin (ProT) zymogen to active -thrombin (T).

Persistent Leukoencephalopathy Following H1N1 Infection Associated With a Novel MYRF Variant (p.Gly735Asp)

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Mutations in myelin regulatory factor (MYRF) are linked to demyelinating disorders. We report a 38‐year‐old male who developed acute symmetric leukoencephalopathy mimicking a stroke following an influenza A virus infection. While clinical symptoms markedly improved with corticosteroids, MRI revealed persistent white matter lesions, contrasting

Variably Protease‐Sensitive Prionopathy: Two New Cases With Motor Neuron‐Dementia Syndrome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT We describe two patients with variably protease‐sensitive prionopathy (VPSPr) who developed progressive upper motor neuron symptoms, insomnia, behavioral and cognitive decline, compatible with primary lateral sclerosis associated with frontotemporal dementia (FTD).

Broad activation of the ubiquitin-proteasome system by Parkin is critical for mitophagy [PDF]

, 2011
Parkin, an E3 ubiquitin ligase implicated in Parkinson's disease, promotes degradation of dysfunctional mitochondria by autophagy. Using proteomic and cellular approaches, we show that upon translocation to mitochondria, Parkin activates the ubiquitin ...

Serum Soluble Mediator Signatures of Lupus Nephritis: Histologic Features and Response to Treatment

Arthritis Care &Research, EarlyView.
Objective Lupus nephritis (LN) management remains challenging, and novel noninvasive biomarkers are needed. This study quantified serum soluble mediators in the Accelerating Medicines Partnership (AMP) LN cohort to identify biomarkers of histologic features and treatment response.
