Enhancing glycolysis attenuates Parkinson’s disease progression in models and clinical databases

Parkinson’s disease (PD) is a common neurodegenerative disease that lacks therapies to prevent progressive neurodegeneration. Impaired energy metabolism and reduced ATP levels are common features of PD. Previous studies revealed that terazosin (TZ) enhances the activity of phosphoglycerate kinase 1 (PGK1), thereby stimulating glycolysis and increasing cellular ATP levels. Therefore, we asked whether enhancement of PGK1 activity would change the course of PD. In toxin-induced and genetic PD models in mice, rats, flies, and induced pluripotent stem cells, TZ increased brain ATP levels and slowed or prevented neuron loss. The drug increased dopamine levels and partially restored motor function. Because TZ is prescribed clinically, we also interrogated 2 distinct human databases. We found slower disease progression, decreased PD-related complications, and a reduced frequency of PD diagnoses in individuals taking TZ and related drugs. These findings suggest that enhancing PGK1 activity and increasing glycolysis may slow neurodegeneration in PD.

We previously established CGRP-modified BMSCs that express the CGRP gene and demonstrated that this elevated CGRP expression promotes osteogenic differentiation of BMSCs. The current study investigated the therapeutic effects of CGRP-modified BMSCs combi...

B cells are important to the coordination of the immune response. Dysfunctional B cells emerge with age, however, leading to autoimmunity and contributing to immunosenescence, the name given to the general age-related decline in effectiveness of the immune system. Animal studies have shown that selective destruction of the entire B cell population is beneficial in older individuals, improving the immune response: the cells are quickly replaced, but the harmful portion will take much longer to reemerge. Setting all of this to one side, the open access review here is largely focused on more subtle changes in the B cell popul...

In vitro treatment with 4 μM CHIR during the late 2 days of a 4-day suspension culture period was most effective at promoting mesodermal differentiation. The resulting EBs showed a significant increas...

The synergistic crosstalk between osteodifferentiating stem cells and endothelial cells (ECs) gained the deserved consideration, shedding light on the role of angiogenesis for bone formation and healing. A deep understanding of the molecular basis underlying the mutual influence of mesenchymal stem cells (MSCs) and ECs in the osteogenic process may help improve greatly bone regeneration. Here, the authors demonstrated that osteodifferentiating MSCs co-cultured with ECs promote angiogenesis and ECs recruitment. Moreover, through the use of 3D co-culture systems, we showed that ECs are in turn able to further stimulate the o...

Authors: Freeman FE, Browe DC, Nulty J, Von Euw S, Grayson WL, Kelly DJ Abstract Interconnected porosity is critical to the design of regenerative scaffolds, as it permits cell migration, vascularisation and diffusion of nutrients and regulatory molecules inside the scaffold. 3D printing is a promising strategy to achieve this as it allows the control over scaffold pore size, porosity and interconnectivity. Thus, the aim of the present study was to integrate distinct biofabrication strategies to develop a multiscale porous scaffold that was not only mechanically functional at the time of implantation, but also faci...

We have previously shown in the Drosophila Genetic Reference Panel (DGRP) that resistance to infection is highly heritable, but our understanding of how the effects of genetic variants are channeled through distinct molecular layers is still limited. To address this, we employed a systems genetics approach on the gut transcriptomes from 38 control and orally...
