We examined whether Rhy promotes this regulation in bone marrow human mesenchymal stromal cells (BM-hMSCs). Results revealed (i) Rhy modulated biological activity by regulating the mitochondria, N-methyl-D-aspartate receptor subunit, and levels of FGFβ (basic fibroblast growth factor), BDNF (brain-derived neurotrophic factor), OXTR (oxytocin receptor) and ATP (Adenosine triphosphate); (ii) Rhy altered expression level of BM-MSC proliferation/differentiation-related transcription genes; and (iii) interestingly, Rhy amplified the glycolytic flow ratio and lactate dehydrogenase activity while reducing pyruvate dehydrogen...

Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disorder that causes muscle weakness, disability, and eventually death, with a median survival of 3-5 years and affecting all populations with a rise among Hispanics. ALS patients are mostly cared for by family caregivers (FCGs). FCGs often experience burden, high depression rates, psychological distress and impaired quality-of-life. Also, FCGs may not be able to leave their homes to access resources. Social media might be a way to accessing support, but little is known about quality and quantity of ALS FCGs ’ resources.

c Šket The hexanucleotide expansion GGGGCC located in C9orf72 gene represents the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar dementia (FTLD). Since the discovery one of the non-exclusive mechanisms of expanded hexanucleotide G4C2 repeats involved in ALS and FTLD is RNA toxicity, which involves accumulation of pathological sense and antisense RNA transcripts. Formed RNA foci sequester RNA-binding proteins, causing their mislocalization and, thus, diminishing their biological function. Therefore, structures adopted by pathological RNA transcripts could have a key r...

AbstractPrion diseases are fatal infectious neurodegenerative disorders in human and animals caused by misfolding of the cellular prion protein (PrPC) into the infectious isoform PrPSc. These diseases have the potential to transmit within or between species, and no cure is available to date. Targeting the unfolded protein response (UPR) as an anti-prion therapeutic approach has been widely reported for prion diseases. Here, we describe the anti-prion effect of the chemical compound Sephin1 which has been shown to protect in mouse models of protein misfolding diseases including amyotrophic lateral sclerosis (ALS) and multip...

AbstractAmyotrophic lateral sclerosis (ALS) is a devastating motoneuron (Mn) disease without effective cure currently available. Death of MNs in ALS is preceded by failure of neuromuscular junctions and axonal retraction. Neuregulin 1 (NRG1) is a neurotrophic factor highly expressed in MNs and neuromuscular junctions that support axonal and neuromuscular development and maintenance. NRG1 and its ErbB receptors are involved in ALS. Reduced NRG1 expression has been found in ALS patients and in the ALS SOD1G93A mouse model; however, the expression of the isoforms of NRG1 and its receptors is still controversial. Due to the re...

ConclusionWhile our sample size limits statistical confidence about the differences observed in this study, it was possible to measure and quantify inter-individual and cohort variability in a non-invasive manner. Our study also shows the potential for MRI based measurements of CSF geometry and flow to provide information about   the hydrodynamic environment of the spinal subarachnoid space. These dynamics may be studied further to understand the behavior of CSF solute transport in healthy and diseased states.

Abnormal accumulation of TAR DNA-binding protein 43 (TDP-43), a DNA/RNA binding protein, is a pathological signature of amyotrophic lateral sclerosis (ALS). Missense mutations in the TARDBP gene are also found in...

This study provides strong evidence that following a healthy lifestyle can substantially extend the years a person lives disease-free." Commentary on Recent Evidence for Cognitive Decline to Precede Amyloid Aggregation in Alzheimer's Disease https://www.fightaging.org/archives/2020/01/commentary-on-recent-evidence-for-cognitive-decline-to-precede-amyloid-aggregation-in-alzheimers-disease/ I can't say that I think the data presented in the research noted here merits quite the degree of the attention that it has been given in the popular science press. It is interesting, but not compelling if its role...
