Retraction Note to: Circular RNA circ_0003204 inhibits proliferation, migration and tube formation of endothelial cell in atherosclerosis via miR-370-3p/TGFβR2/phosph-SMAD3 axis

Retraction to: J Biomed Sci (2020) 27:11 10.1186/s12929-019-0595-9

The Editor-in-Chief has retracted this article. Concerns were raised regarding a number of figures, specifically:

• Figure 2E: the CTL/NC panel appears to partially overlap with the oxLDL/SIS3 panel of Fig. 5G;

• Figure 2F: the 0 h si-circ_0003204 panel appears to be identical with the 0 h panel of Fig. 5C;

• Figure 2G: the CTL and ox-LLD panels for si-circ_0003204 appear to partially overlap;

• Figure 2G: the ox-LDL panels for si-NC and NC appear to partially overlap;

• Figure 5B: the inhibitor NC and miR-370 inhibitor panels for siRNA NC appear to be identical;

• Figure 5C: the last panel appears to be identical to the second panel of Fig. 5H.

The Editor-in-Chief therefore no longer has confidence in the reliability of the data reported in the article.
