An Criminalized Truth Related To Etoposide Showcased By An Old Professional
We measured the levels PGC-1�� coregulated genes that play important roles in mitochondrial function and oxidant metabolism including nuclear respiratory factor-1 (NRF-1), copper/zinc superoxide dismutase (SOD1), manganese SOD (SOD2), glutathione peroxidase (GPx1), catalase (CAT), mitochondrial uncoupling proteins (UCP2 and UCP3), mitochondrial transcription factor A (Tfam) and the oxidative phosphorylation regulators, ATP5b, cytochrome C (CytC) and cytochrome C oxidase (COX II and IV) (Figure?6A and Figure?S5A). In addition, the levels of other Etoposide cost genes containing IRS/PLM in their promoter including PEPCK, G6Pase, insulin-like-growth-factor-binding protein 1 (IGFBP-1), tyrosine aminotransferase (TAT), and apolipoprotein Autophagy C III (APOC3) were monitored along with PGC-1�� to assess whether PGC-1�� is selectively affected in PD (Figure?6A and Figure?S5A). The levels of PARIS and parkin were also assessed as controls. We find that PGC-1�� and NRF-1 mRNA are downregulated in PD SN and striatum compared to control SN and striatum (Figure?6A and Figure?S5A). In PD SN ATP5B is also significantly downregulated and CAT is significantly upregulated (Figure?6A). All other PGC-1�� dependent genes are not significantly altered (Figure?6A and Figure?S5A). In addition there is no significant change in the levels of the IRS/PLM responsive transcripts PEPCK, G6Pase and IGFBP-1 (Figure?6A and Figure?S5A). TAT and APOC3 are not detectable. No significant alteration in the mRNA level of PARIS and parkin is observed between PD and control SN and striatum (Figure?6A and Figure?S5A) indicating that the upregulation in PARIS protein levels (see Figures?4C and 4D) are most likely due to impairment of parkin E3 ubiquitin ligase activity. Moreover, the absence of an alteration in the mRNA levels of PARIS and parkin suggest that the changes in the mRNA levels of PGC-1�� and NRF-1 are specific and not due to the degenerative process that occurs in PD. As shown above (see Figures?4C and 4D) PARIS protein is upregulated almost 3-fold in PD SN (Figures 6B and MEK inhibition 6C) and greater than two-fold in PD striatum (Figure?S5B and S5C) compared to control SN and striatum respectively. Accompanying the upregulation of PARIS is the downregulation of PGC-1�� and NRF-1 in SN (Figures?6B and 6C) and striatum (Figures S5B and S5C). There is a trend toward redistribution of parkin from the soluble to insoluble fraction in SN (Figures?6B and 6C) and parkin shifts from the soluble to insoluble fraction in PD striatum (Figures S5B and S5C). There is a strong negative correlation between the protein levels of PARIS and PGC-1�� (R2?= 0.5195, p?
