Dear Readers:
Although I checked our manuscript many times before publication, a minor error is still present in Fig. 1 in our article. The names of recombinant plasmids should be pIRES2-EGFP-LTR-gag (not pBR322-HBV) in Fig. 1-G1, 1-H2 and m-pIRES2-EGFP-LTR-gag (not m-pBR322-HBV) in Fig. 1-G2, 1-H3. The description on these plasmids in the text and legends of the article are right.
Beside HIV-1, my group is also investigating the relationship between DNA methylation and gene expression of HBV. Thus, my assistant confused names of plasmids of both viruses in preparing the figures.
I sincerely apologize for my carelessness and mistake to bring you the inconvenience.
Best wishes.
Tianhua Huang,
