The protein levels of α-SMA, COL1A1, Smad2, p-Smad2, PED7A, PED4A, PKA, p-PKA, total Ras-proximate-1 (Rap1), Guanosine-5′-triphosphate (GTP)-Rap1, and exchange protein directly activated by cAMP 1 (Epac1), cAMP-response element-binding protein (CREB) and p-CREB were examined by immunoblotting following the methods described before (Liu et al., 2018 (link)) using the antibodies listed below: anti-α-SMA (ab5694, Abcam), anti-COL1A1 (ab34710, Abcam), anti-Smad2 (ab40855, Abcam), anti-p-Smad2 (ab53100, Abcam), anti-PDE4A (ab14607, Abcam), anti-PDE4B (ab170939, Abcam), anti-PDE4C (ab170939, Abcam), anti-PDE4D (ab171750, Abcam), anti-PKA (BS-0520R, Woburn, MA, United States), p-PKA (ab75991, Abcam), anti-GTP-Rap1 (ab32373, Abcam), anti-Rap1 (ab14404, Abcam), anti-Epac1 (ab109415, Abcam), anti-CREB (ab31387, Abcam), anti-p-CREB (ab32096, Abcam), and anti-Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) (ab8245, Abcam) and then with HRP-conjugated secondary antibody. Enhanced chemilumescent (ECL) substrates (Millipore, MA, United States) were used for signals visualization using GAPDH as an endogenous protein for normalization.

Western Blot Analysis of Cell Signaling Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
Briefly speaking, Western immunoblotting was performed according to the protocol presented previously17 (link). The primary antibodies were rabbit polyclonal to PDE4a (Catalog No.: ab14607, Abcam, USA), mouse monoclonal to E-cadherin (Catalog No.: ab1416, Abcam, USA), rabbit polyclonal to N-cadherin (Catalog No.: ab18203, Abcam, USA), mouse monoclonal to Vimentin (Catalog No.: ab18203, Abcam, USA), and mouse monoclonal to β-actin (Catalog No.: ab8226, Abcam, USA). After incubated with the primary antibodies, the blots were then incubated respectively with secondary antibodies conjugated with HRP (Abcam, USA). Protein levels were detected using the HyGLO HRP detection kit from Denville (Metuchen, NJ, USA). β-actin was used as the internal 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.
