Salazar1, Christin Glorioso2 and Sergiy Libert1*AbstractParkinson’s disease is characterized by progressive death of dopaminergic neurons, top to motor and cognitive dysfunction. Epidemiological studies consistently show that the usage of tobacco reduces the danger of Parkinson’s. We report that nicotine reduces the abundance of SIRT6 in neuronal culture and brain tissue. We uncover that reduction of SIRT6 is partly accountable for neuroprotection afforded by nicotine. On top of that, SIRT6 abundance is higher in Parkinson’s patient brains, and decreased in the brains of tobacco customers. We also identify SNPs that promote SIRT6 expression and simultaneously associate with an enhanced risk of Parkinson’s. Moreover, brain-specific SIRT6 knockout mice are protected from MPTP-induced Parkinson’s, when SIRT6 overexpressing mice develop extra severe pathology. Our information suggest that SIRT6 plays a pathogenic and pro-inflammatory role in Parkinson’s and that nicotine can provide neuroprotection by accelerating its degradation. Inhibition of SIRT6 can be a promising strategy to ameliorate Parkinson’s and neurodegeneration.

No therapy exists to prevent neuronal death or halt advancement of PD [40]. Numerous genetic danger components have been identified in familial circumstances of Parkinson’s, for example mutations in -Synuclein, LRRK2, and Parkin [13], having said that, it is actually nevertheless not clear what causes the death of DA neurons at sophisticated age in the majority of sporadic circumstances, which constitute over 93 of PD [53]. Epidemiological studies have identified various things that improve prevalence of PD, for instance exposure to herbicides, specific dairy products [24], traumatic brain injury [3], or being overweight [12]. Surprisingly, in 1959 a U.S. Government-sponsored study of wellness among 200,000 veterans reported that smoking decreased PD deaths by 64 [15]. The unfavorable association* Correspondence: [email protected]; [email protected] 1 Department of Biomedical Sciences, Cornell University, Ithaca, NY 14853, USA Full list of author details is out there at the finish in the articlebetween tobacco use and PD and has been firmly established in more than seventy independent studies [10, 15, 33, 34, 39, 57, 66]. Mainly because tobacco smoke is usually a potent carcinogen, the “competing death risk” theory h.
