<p>(<b>A</b>) Protein expression of p-STAT3 pathway in triple negative breast cancer cell lines, SUM159 and MDA-MB-231, after treatment with AuNPs, non-targeting siRNA in siPORT, STAT3 targeting siRNA in siPORT, non-targeting SNVs, and STAT3 targeting siRNA in SNVs. (<b>B</b>) Primary mammosphere forming efficiency from breast cancer cells after 3 days treatment with AuNPs, STAT3 siRNA in siPORT, in PLL and STAT3 targeting siRNA in SNVs. (<b>C</b>) Forming efficiency of secondary mammospheres was plotted after primary mammospheres were collected, disassociated, and re-seeded in fresh mammosphere media for 3 days. (* = statistical significance, n = 6, p<0.05).)
