چکیده

Recently, the development of Parkinson’s disease (PD) has Background: been linked to a number of genetic risk factors, of which the most common is glucocerebrosidase (GBA) mutations. We investigated PD and Gaucher Disease (GD) patient derived skin Methods: fibroblasts using biochemistry assays. PD patient derived skin fibroblasts have normal glucocerebrosidase Results: (GCase) activity, whilst patients with PD and GBA mutations have a selective deficit in GCase enzyme activity and impaired autophagic flux. This data suggests that only PD patients with a GBA mutation Conclusions: have altered GCase activity and autophagy, which may explain their more rapid clinical progression. 1,2 3 2 4

Comparison of a Suggested Model of Fibrosis in Human Dermal Fibroblasts by Serum from Systemic Sclerosis Patients with Transforming Growth Factor β Induced in vitro Model

Systemic sclerosis (SSc) is a chronic autoimmune disease, featuring fibrosis in multiple organs. The serum from SSc patients contain inflammatory mediators, contributing to SSc pathogenesis and could be used to develop cell culture models. Here, we compared the fibrotic effects of serum samples from SSc patients with TGFβ1 on human dermal fibroblasts (HDFs). HDF cells were cultured in four diff...

Parkinson disease-linked GBA mutation effects reversed by molecular chaperones in human cell and fly models

GBA gene mutations are the greatest cause of Parkinson disease (PD). GBA encodes the lysosomal enzyme glucocerebrosidase (GCase) but the mechanisms by which loss of GCase contributes to PD remain unclear. Inhibition of autophagy and the generation of endoplasmic reticulum (ER) stress are both implicated. Mutant GCase can unfold in the ER and be degraded via the unfolded protein response, activa...

Cytotoxic and Anticancer Effects of ICD-85 (Venom Derived Peptides) in Human Breast Adenocarcinoma and Normal Human Dermal Fibroblasts

      ICD-85 (venom derived peptides) has anti-proliferative effect and anti-angiogenesis activity on cancer cells. This study was performed to test the effect of ICD-85, on Human breast adenocarcinoma (MCF-7) and normal Human Dermal Fibroblasts (HDF) cell lines. In this experimental study, Mitochondrial activity, Neutral red uptake, Lactate dehydrogenase (cell necrosis), and cell morphology we...
