Correction: Overexpression of cathepsin f, matrix metalloproteinases 11 and 12 in cervical cancer

After the publication of our work in BMC Cancer [1], we became aware of an omission. In the Methods section, under the subtitles "Cell lines and tissue samples for cDNA arrays" and "cDNA probe preparation" we failed to quote the original description of how the cDNA library was generated, published in the Journal Archives of Medical Research as quoted below [2]. Since this initial analysis, further data mining has been performed, and the obtained results answer very different biological questions [1].
