Retraction: Gambogic Acid Inhibits STAT3 Phosphorylation through Activation of Protein Tyrosine Phosphatase SHP-1: Potential Role in Proliferation and Apoptosis

This article (1) has been retracted at the request of the editors. An internal journal investigation determined that the pSTAT3 immunoblot in Fig. 5C appears to have been inappropriately digitally manipulated. In addition, an image of the same field of cells was used to represent the effects of SHP-1 siRNA under two experimental conditions (control and gambogic acid treatments) in Fig. 5D. The original research records related to Fig. 5D were not available during an institutional investigation.

A copy of this Retraction Notice was sent to the last known email addresses for all four authors. Two authors (S. Prasad and B.B. Aggarwal) did not agree to the retraction; the two remaining authors (M.K. Pandey and V.R. Yadav) did not respond.
