Synaptic Changes in Mice Lacking Alpha- and Gamma-Synucleins
Background: Alpha-synuclein is a key protein involved in the pathogenesis of Parkinson disease (PD). Its intermediate aggregated forms disturb the normal function of dopaminergic (DA) neurons.

Parkinson's disease (PD) is the most common neurodegenerative disease
Metabolic impairment of alpha-synuclein protein is considered to be the central event in PDpathogenesis. Recent studies explored usage of alpha-synuclein in peripheral fluids as a biomarker of PD, however alpha-synuclein level in the CSF and plasma is ...

Expansion of the Parkinson disease-associated SNCA-Rep1 allele upregulates human alpha-synuclein in transgenic mouse brain. [PDF]
Alpha-synuclein (SNCA) gene has been implicated in the development of rare forms of familial Parkinson disease (PD). Recently, it was shown that an increase in SNCA copy numbers leads to elevated levels of wild-type SNCA-mRNA and protein and is ...

Associations of sleep characteristics with alpha‐synuclein in cerebrospinal fluid in older adults
Objective Sleep disorders as a preclinical symptom of synucleinopathies become more prevalent in older adults. Synucleinopathies might be caused by the abnormal aggregation of alpha‐synuclein in the brain, which was indicated by alpha‐synuclein levels in

Activation of the DNA damage response in vivo in synucleinopathy models of Parkinson\xe2\x80\x99s disease [PDF]
The involvement of DNA damage and repair in aging processes is well established. Aging is an unequivocal risk factor for chronic neurodegenerative diseases, underscoring the relevance of investigations into the role that DNA alterations may have in the ...

Intercellular transmission of alpha-synuclein [PDF]
An emerging theme in Parkinson’s disease (PD) is the propagation of α-synuclein pathology as the disease progresses. Research involving the injection of preformed α-synuclein fibrils (PFFs) in animal models has recapitulated the pathological spread observed in PD patients.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
