Samples were homogenized in RIPA buffer (50 mM Tris-HCl pH 7.4, 1% TX, 150 mM NaCl, 2 mM EDTA and protease/phosphatase inhibitor cocktail). Then, 20 µg of homogenate were analysed by western blot (WB) using standard procedures. Membranes were incubated overnight at 4 °C with primary antibodies: TH (1:1000, AB152, Millipore), D1R (1:500, sc-14001, Santa Cruz), D2R (1:500, AB5084P, Millipore), DARPP-32 (1:1000, AB10518, Millipore), P-DARPP-32-Thr34 (1:1000, AB9206, Millipore), LAMP-1 (1:500, sc-19992, Santa Cruz), p62 (1:500, H00008878-M01, Tebu-bio), LC3B (1:1000, NB100-2220, Novus-Bio) and GAD65 (1:1000, BK3988S, Cell Signaling). β-actin (1:5000, MAB1501, Millipore) was used as housekeeping. Immunoreactivity was detected by chemiluminescence and bands quantified by densitometry using ImageJ software. We reported normalized data to the WT group because we calculated the percentage relative to the control for each blot, to correct for any type of differences relative to different gels (for example, recycling of primary antibody or time to ECL exposure). HPLC was performed as previously described64 . Tissue levels of DA (pg/mg wet weight) were used for statistical analysis.

Western Blot Analysis of Dopamine Signaling

Muscle and NAc samples were pulverized and homogenized as described previously [39] (link), and protein concentrations were determined via the Bradford protein assay. Proteins (50 μg) were resolved by SDS-PAGE for Western blot analysis [40] (link). Antibody-bound proteins were visualized on film using chemiluminescence detection reagents (Perkin–Elmer Life Sciences). Protein bands were scanned, and quantitated by densitometry (ImageJ, National Institute of Health). Commercially available primary antibodies were against DARPP32 (AB-10518); pThr34-DARPP32 (AB-9206); D1R (ABN20; all Millipore, Temecula, CA); TH (2792), pThr75-DARPP32 (2301), ΔFosB (9890; all Cell Signaling Technology, Danvers, MA); D2-type dopamine receptor (D2R; ab85367; Abcam, Cambridge, MA); and glucose transporter 4 (GLUT4; sc-7938), hexokinase 2 (HXK2; sc-6521; all Santa Cruz Biotechnology, Dallas, TX). Loading was controlled using glyceraldehyde 3-phosphate dehydrogenase (GAPDH; sc-25337; Santa Cruz Biotechnology) or β-tubulin (05–661; Millipore, Temecula, CA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
