Correction to: Loss of LKB1 disrupts breast epithelial cell polarity and promotes breast cancer metastasis and invasion (Journal of Experimental & Clinical Cancer Research, (2014), 33, 1, (70), 10.1186/s13046-014-0070-0)

Following the publication of the original article [1], the authors identified errors in Figure 5c. The GAPDH protein band in Figure 4A and Figure 5C were obtained from two separate replicate experiments. However, the LKB1 protein band in both figures originated from the same experimental set. Therefore, the LKB1 band in Figure 5C requires replacement. Fig. 5c: LKB1 band needs replacement. The corrected figures are provided below: The corrections do not affect the overall results, discussion, or conclusion of the article. LKB1 was localized at adheren junctions and regulated the expressions of EMT markers. (A) MCF-10 A was stained for LKB1 (green), E-cadherin (red) and DAPI (blue). (B) Expressions of EMT markers in control and LKB1 overexpressing MDA-MB-435 s. (C) MCF-7 cells were transfected with non-targeting siRNA (NT) or siLKB1(1342/1972). The protein levels of E-cadherin, N-cadherin and α-SMA were determined by western blot LKB1 was localized at adheren junctions and regulated the expressions of EMT markers.
