The combination of genetics and genomics in Parkinsons disease has recently begun to unveil molecular mechanisms possibly underlying disease onset and progression In particular catabolic processes such as autophagy have been increasingly gaining relevance as post-mortem evidence and experimental models suggested a participation in neurodegeneration and alpha-synuclein Lewy body pathology
Copper is a trace element that plays many important roles in the brain one of the most copper-rich organs of the body It is an essential structural component and cofactor for many proteins and enzymes including various effectors of synaptic plasticity suggesting that it has an important role in regulating the cellular processes underlying learning and memory [1 2]
Regulatory small RNAs which range in size from 20 to 24 nucleotides are ubiquitous components of endogenous plant transcriptomes as well as common responses to exogenous viral infections and introduced double-stranded RNA (dsRNA) Endogenous small RNAs derive from the processing of helical RNA precursors and can be categorized into several groups based on differences in biogenesis and

The mechanism of drug-induced iron-dependent cell death in RAS-driven cancers relies on cystine/glutamate antiport and the accumulation of hydroxylated lipids This type of death is similar to glutamate-induced excitotoxicity in neurons and both types of cell death can be blocked with a specific small-molecule inhibitor called ferrostatin-1
