Western blot and coimmunoprecipitation analyses were conducted as described in our previous research.9 (link) Antibodies against the following proteins were used: gankyrin (ab182576, Abcam), HMGB1 (ab18256, Abcam), STAT3 (ab32500, Abcam), p-STAT3 (ab76315, Abcam), NONO (11058, Proteintech), AR (ab74272, Abcam), and GAPDH (#2118S, CST). To analyze gankyrin, HMGB1 and NONO protein interactions, co-immunoprecipitation assays were used with antibodies against the following: gankyrin (ab182576, Abcam), HMGB1 (ab18256, Abcam), and NONO (11058, Proteintech). The GAPDH was utilized as an internal reference.

Paraffin-embedded sections of prostate cancer samples were deparaffinized, rehydrated, and microwaved for 20 min in Tris/EDTA buffer or citric acid buffer to retrieve antigens. Staining was carried out using primary antibodies against the following proteins: Gankyrin (ab182576, Abcam), HMGB1 (ab18256, Abcam), CD68 (M0876, Dako), STAT3 (ab32500, Abcam), p-STAT3 (ab76315, Abcam), and NONO (11058, Proteintech). Samples were scored semiquantitatively according to the percentage of staining intensity and positive cells using the H score (range 0–300), as described previously.20 (link) All the immunohistochemistry assays were repeated three times.

The western blot analysis was performed as described in our previous study20 (link). The primary antibodies used in the this study were listed as follows: rabbit anti-gankyrin (ab182576), rabbit anti-STAT3 (ab32500), and rabbit anti-STAT3 (Phospho 727) (ab30647), rabbit anti-eotaxin-2 (CCL24) (ab203586), rabbit anti-CCR3 (ab32512) from Abcam (Cambridge, MA, USA) and rabbit anti-GAPDH (#2118S), rabbit anti-p44/42 MAPK (Erk1/2) (#4695), rabbit anti-p44/42 MAPK (Erk1/2) (Phospho Thr202/Tyr204) (#4370), rabbit anti-Akt (#9272), and rabbit anti-Akt (Phospho Ser473) (#9271) from Cell Signaling Technology (Danvers, MA, USA). The secondary antibody used in the assay was anti-rabbit IgG-HRP-linked antibody (#7074S) from Cell Signaling Technology. Coimmunoprecipitation analysis was performed according to previously published protocols20 (link) using the above-mentioned antibodies.

Cells were lysed by RIPA buffer (Beyond) containing protease inhibitor. Then, protein concentration was evaluated using the BCA method. Protein (25 μg) was separated by 10% SDS-PAGE gel and was transferred to PVDF membrane. Afterward, the membrane was blocked with 5% skim milk and incubated overnight with PSMD10 (ab182576, Abcam), α-tubulin (CST, 3873 s, 1:2000) at 37 °C. Secondary antibody (SA0004–1, Porteintech) was added to the membrane and incubated for 2 h at 25 °C. ECL plus (PE0010, Solarbio) and Tanon-5200 CE (Biotanon, Shanghai, China) were used to observe the protein bands. α-tubulin served as the loading control.

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.
