Correction to: miR-762 modulates thyroxine-induced cardiomyocyte hypertrophy by inhibiting Beclin-1

Correction to: Endocrine

https://doi.org/10.1007/s12020-019-02048-y

The original version of this article unfortunately contained the below mistakes. This has been corrected with this erratum.

1. Table. 2 Sequences for primers

The sequences of β-MHC: Forward and Reverse, miR-762 mimic, and miR-762 inhibitor are incorrect. Below are the correct sequences.

β-MHC: Forward 5-TGCAGACATAGAGACCTACCTTC-3

Reverse 5-CAGCATGTCTAGAAGCTCAGG-3

miR-762 mimic: 5-GGGGCUGGGGCCGGGACAGAGC-3

miR-762 inhibitor: 5-GCUCUGUCCCGGCCCCAGCCCC-3

2. Figure 1

2 panels were marked as “f” in Fig. 1. The last “f” panel in the bottom should be “j”.

3. Figure 3.

The panel “l” in Fig. 3, the labels of “3’” and “5’” were inversed, and “WU-Beclin-1-3’UTR” should be “MU-Beclin-1-3’UTR”. Below is the correction.

Fig. 3: Autophagy plays a key role in thyroxine-induced cardiomyocyte hypertrophy.

a. Expression of LC3 and Beclin-1 protein in the heart. b. Transmission electron microscopy of the heart. Autophagic vacuoles are green, and autolysosomes are red, 10000×. c. Immunofluorescence staining of the heart, LAMP2 protein is red, LC3 protein is green, cell nuclei are blue, and autolysosomes are yellow, 200×. d. Semiquantitative analysis of miR-762 gene expression in the heart. e. Semiquantitative analysis of Beclin-1gene expression in the heart. f. Semiquantitative analysis of LC3 protein in the heart. g. Semiquantitative analysis of Beclin-1 protein in the heart. h. Semiquantitative analysis of autophagic vacuoles with transmission electron microscopy. i. Semiquantitative analysis of LAMP2 protein with immunofluorescence staining. j. Semiquantitative analysis of LC3 protein with immunofluorescence staining. k. Semiquantitative analysis of autolysosomes with immunofluorescence staining. l. The sequence of the Beclin-1 3’-UTR (http://www.Ensembl.org/) and binding site between miR-762 and Beclin-1 in mice (http://www.Targetscan.org/). m. Semiquantitative analysis of luciferase activity in 293A cells. (**P < 0.01 vs the control group; n ≥ 9 independent samples for each group)
