Wnt pathway activator TWS119 enhances the proliferation and cytolytic activity of human γδT cells against colon cancer.

γδT cells are a distinct T-cell subset that display unique characteristics regarding T-cell receptor gene usage, tissue tropism and antigen recognition. Adoptive γδT cell transfer therapy has recently been gaining importance as an efficient approach in cancer immunotherapy. However, exploiting γδT cell response for tumour immunotherapy is a challenge due to cell numbers, activities and differentiation states that minimize the clinical therapeutic effects.

Shikonin inhibits prostate cancer cells metastasis by reducing matrix metalloproteinase-2/-9 expression via AKT/mTOR and ROS/ERK1/2 pathways.

Metastasis is one of the most important factors related to prostate cancer therapeutic efficacy. In previous studies, shikonin, an active naphthoquinone isolated from the Chinese medicine Zi Cao, has various anticancer activities both in vivo and in vitro. However, the mechanisms underlying shikonin's anticancer activity are not fully elucidated on prostate cancer cells.
